What Is a Cell Phone PCB?
This is a type of printed circuit board used in the construction of a functioning cell phone motherboard assembly.
The cell phone PCB offers a mounting platform for components necessary in the working of a cell phone.
The engraved conductive pathways in cell phone PCB connects the electronic components.
Cell Phone PCB
Is The Schematic Essential In The Development And Fabrication Of Cell Phone PCB?
Essentially, the schematic design is the blueprint used during the process of development and manufacturing of cell phone PCB.
It determines the circuit board function, design characteristics, and placement of parts.
Moreover, the schematic also lists the PCB hardware.
It includes the cell phone PCB material, components entailed, and any extra materials that will be necessary during the fabrication process.
The cell phone PCB schematic contains all this information in the initial design phase.
After completing the first schematic, you will do a preliminary examination, inspecting potential issues and performing the necessary editing.
Subsequently, you upload the schematic to a PCB design software that performs simulations to confirm operation.
The simulations enable you to detect any design errors that may have been missed in the first schematic examination.
After that, you convert the cell phone PCB electronic design into a “netlist” that details information about components connectivity.
What Are Some Of The Key Considerations When Developing Cell Phone PCB Schematic?
Mobile Phone PCB Parts
While working on the schematic design, you need to consider a few critical basics on cell phone PCB design from the beginning.
Some of the considerations to execute in the schematic creation phase consist of the following:
Choose The Right PCB Panel Size
Choosing the size of PCB most feasible with the cell phone is a basic, though commonly overlooked, best practice.
Through this, there is no space wastage, you maintain traces to a minimal length, and general material costs modestly low.
Nevertheless, it is essential to ensure optimization of the specifications of cell phone PCB design for mass production.
Opting for extremely small board design might not be compatible with large-scale fabrication procedures that create adequate variation between units.
Choose The Right Grid
Grid spacing is normally determined and applied to fit most components. Adhering to the set grid is among the most useful things you can do to prevent spacing problems.
Therefore, it is essential to choose the best grid for the task. In case certain components are not feasible with the grid, you should try finding alternatives, or employ self-designed products.
Perform Design Rule Checks As Much As Attainable
Most manufacturers make the blunder of running DRC software solely at the close of the process of designing cell phone PCB.
This allows small errors and contentious design choices accumulate, leading to more corrective work at the close of the design operation.
Rather, you need to perform DRC on your work as frequent as practicable. This enables you to solve issues picked out by the design rule check as speedily as possible.
Furthermore, it reduces the amount of immense alterations at the close of the design operation.
On this account, you save a lot of time and smoothen the editing operation.
How Many Layers Are Ideal For Cell Phone PCB?
Based on purpose and development tendency of future smartphones, greatly multi-layered cell phone PCBs should be employed as motherboard.
Similarly, low multilayer printed circuit boards as complementing daughter board.
Normally, 10-layer build-up multilayer cellphone PCBs are chosen for the manufacturing of motherboards.
However, this type of PCB can have up to 12 layers since it is extremely complex.
Having more layers within the cell phone PCB permits more wiring and circuitry for more sophisticated applications.
Nonetheless, due to function consolidation because of semiconductor packaging (SiP), there is high probability that layer number will stay intact or even decreased.
Multilayer Cell Phone PCB
Why Should You Use Multilayer Cell Phone PCB?
With respect to design and technicality, multilayer PCB offers a number of advantages. Here are some of the primary benefits of multilayer cell phone PCB:
Enhances Functionality And Abilities
Laminating several layers of circuit board together, you can effectively enhance the performance and potential of cellphone PCB.
You can put more wiring and circuit in the circuit board with more layers.
Can Be Flexible Or Rigid
Multilayer cell phone PCBs can come as either flexible or rigid circuit boards, based on the requirements.
Nevertheless, adding more layers to the board makes it less flexible.
As you are bonding one layer over the other, this produces a compact board that saves space.
Multiple layers enable fabrication of high capacity, yet smaller footprint cell phone PCB, which is useful for smaller gadgets.
Owing to the layered structure of this type of cell phone PCB, there is no need of using connectors for independent PCBs.
This facilitates simplified fabrication process that besides saving on space, also lowers the general weight of the PCB.
Generally, multilayer cell phone PCBs are usually of better quality in comparison to conventional PCBs.
This is on the ground that more planning, designing and financing is placed into the creation of these circuit boards.
Despite the high cost of multilayer cell phone PCB, you compensate for this in terms of capability and performance.
The boards are typically engineered to be a single unit making mounting them onto the mobile phone much easier.
How does Laminate Multilayer Vs. Build-Up Multilayer (BUM) Fabrication Technology of Cell Phone PCB Compare?
Laminate Multilayer Technology
This is a kind of multilayer cell phone PCB fabrication technique that is presently being used widely.
It employs a substractive procedure to produce the layers of the printed circuit board.
You achieve connection between layers through steps of lamination, mechanical boring, copper and electroless copper plating.
Eventually, you do solder masking, solder coating and silkscreening to finalize on the multilayer cellphone PCB manufacturing.
Here, you apply coated insulating dielectric to the PCB substrate to create through holes and leads.
The application is performed through copper electroplating and chemical copper plating.
Also, the process goes on repeatedly until you produce the multilayer cell phone PCB with desired layer count.
The common properties of BUM cell phone PCB include:
- Thin substrate layer
- Narrow trace spacing and width
- Small via diameter that makes it high density.
Therefore, BUM PCB technology is ideal for IC-grade high-density packaging.
Are There Flexible Cell Phone PCB?
Yes, there are flexible cell phone PCBs that can endure bending about close curvature radii to put everything in a restricted footprint.
They are fabricated with soft insulating materials like laminated plastics that make them lighter compared to rigid mobile phone PCBs.
Flexible cell phone printed circuit boards place different manufacturing limitations on designers compared to rigids types.
FPCBs employ mechanically rolled copper foil because they can endure bending stresses better than electrodeposited copper applied in rigid cell phone PCBs.
Though manufacturing of flexible cell phone PCB is comparatively expensive, they can decrease the general cost of production of the gadget.
This is because they eliminate the necessity for other components like wire harnesses.
Similar to rigid cell phone PCBs, you can produce flexible cell phone PCBs into single-, double- or multi-layer configurations.
What Are the Key Components of Cell Phone PCB?
The cell phone PCB is presumed to be the brain section of the mobile phone. It operates the whole system.
There are various parts of the cell phone PCB that function together to facilitate the proper working of the phone.
Parts of cell phone PCB
Cell phone circuit boards comprise of a number of computer chips. You will find both analog-to-digital and digital-to-analog conversion ICs in the PCB.
The ICs transform the outgoing analog audio signals to digital, similarly transform the incoming digital audio signals to analog.
Also, the digital signal processor of the circuit board helps in signal manipulation calculations in a very quick way. It is useful in both decompression and compression of signals.
Here are some of the common ICs found in cell phone PCB:
- Logic IC
- Power IC
- Network IC
- Audio IC
- Charging IC
ROM And Flash Memory Chips

The microprocessor is responsible for all the tasks to be carried out by the keyboard and display section of the cell phone.
It also concentrates on the control signals and command options of the phone, and assists in linking all key functions of the keyboard.
Parts of cell phone PCB
How Should You Place And Route The Components Of Cell Phone PCB?
You need to place the cell phone PCB components in this order to achieve the best performance:
- Power circuitries
- Precision and sensitive circuitries
- Vital circuit modules
Here are some of the guidelines for components placement during cell phone PCB assembly:
Categorize Parts By Function
Make sure that you categorize the components based on their operational block. Case in point, you should not place power management parts together with analog modules.
Standardize Components Orientation
You should align components like ICs in one direction. This ensures an efficient cell phone PCB assembly process and minimizes probability of making placement errors.
Furthermore, components alignment in similar direction minimizes soldering blunders, which are popular causes of failure in cell phone PCB.
Mount Components Far From Heat Dissipating Sections
Make sure you do not mount near voltage regulator, op-amp, or additional heat emitting elements.
Give Room For Copper Traces
During placement of cell phone PCB components, make sure to leave adequate space for copper tracks to pass through. This allows you to perform routing successfully.
- You should desist from mounting components directly adjacent to plated thru-hole modules on the soldered PCB side.
Install Board-to-Wire Connectors Close to PCB boarder
Apart from making the cell phone PCB appear organized, doing this also hinders unnecessary interaction with other board parts.
Why Should You Be Keen On Technological Design Of Cell Phone PCB?
Technological design of cell phone PCB is very critical since it serves a key purpose in fabricating PCBs efficiently at low expense.
The modern surface mount technology requires you factor in the fabrication issues right from the start.
This is because of the SMT complexity, because any design file modification will definitely result in delayed fabrication time and raised development cost.
Even an alteration in pad position needs rerouting and remanufacturing of solder paste stencil.
It gets more challenging for analog cell phone circuitries that require redesigning and retesting.
However, if you leave the issues unresolved, you will incur more losses during mass production. For that matter, you must be very keen on technological issues from the start.
One basic principle: the earlier you resolve the technological problems the better.
Which Are The Key Factors To Consider With Regard To Technological Design Of Cell Phone PCB?
Here are the primary factors that you should take into consideration with respect to technological design of cell phone printed circuit board:
- Fiducial marks, positioning hole and transmission line feasible with automatic fabrication and assembly.
- Panels related to production efficiency.
- PCB material, PCB Assembly technique, packaging type and component distribution, pad and soldermask design associated with pass percentage.
- Component spacing and design of test pad related to inspection, redesign and testing.
- Silkscreen or corrosion features related to assembly, debugging and cabling.
How Should You Place Fiducial Marks In Cell Phone PCB?
Android mobile phone PCB
Also referred to as circuitry pattern recognition marks, fiducial marks enable SMT placement machine to precisely position and mount cell phone PCB components.
The equipment locates the circuitry pattern by giving common measurable spots.
Fiducial marks are made by removing the soldermask coating in a circular portion of the PCB to expose the copper plating underneath.
You can treat, gold-plate or solder-coat the center metallic disc, though it is usually left as bare copper when not a current-conducting contact.
Alternatively, you can cover the fiducials using clear soldermask lacquer.
To reduce rounding mistakes, it was preferred to place the fiducial marks in the same grid used to mount the components.
Nonetheless, this is not often possible with high-density cell phone PCBs nor is it a necessity anymore with advanced high-precision equipment.
As a general rule, every face of daughter board in cell phone need to have a minimum of two fiducial marks.
If space is very limited, you can flexibly arrange them.
The fiducial marks should be in the form of a circular graphic with a diameter of 40mil (1mm).
With distinction between material color and surrounding, soldermask area should be 40mil (1mm) greater than the fiducial and no character is permitted.
If the cell phone PCB real estate is very small, you can make the soldermask area size to be 0.5mm broader.
However, you should not design solder pads having similar color within a 3mm range.
Furthermore, fiducial marks on one cell phone PCB need to have similar internal background. Simply, they should be feasible in copper coating.
An independent fiducial mark having no routing about needs to be engineered to be a shielding circle. It should have a 1mm circular width and 3mm internal diameter.
Additionally, the fiducial marks should feature coordinate figures that should not be considered as symbols after cell phone PCB design.
Which Is The Recommended Panel Design For Cell Phone PCB?
There are two main panel designs ideal for cell phone circuit board:
Double-Side V-Groove Panel
This technique works best for square cell phone PCBs with features of neat edges after separation and reduced production cost.
Due to these reasons, it is the first recommendation.
Typically, you apply a 30-degrees angle with the thickness being ¼ or 1/3 of the PCB thickness.
Nevertheless, this technique is not suitable for cell phone circuit boards having ICs with QFN or BGA packages.
Long-Slot Hole Plus Round Hole
You should apply this panel design in mother boards having layers exceeding four. Other daughter boards like SIM card, LCD, TF card and button board should choose panel technique depending on the shape of PCB.
It is recommended that you apply long-slot hole plus round hole to irregular or arc shapes.
Why Should You Consider Cell Phone PCB Panelization?
You must consider panelization to ensure efficient manufacturing of cell phone circuit board. It contributes to improvement in fabrication efficiency, thus reducing the lead time.
Moreover, panelization is the most efficient fabrication technique for miniature cell phone PCBs having irregular shape.
Also, panelization is essential for cell phone PCB assembly as it reduces labour cost and convenient for controlling product quality.
Cell Phone PCB Panelization
Nonetheless, there are some limitations to the PCB panelization.
The size of the entire cell phone PCB panel must be compatible with fabrication abilities of the automation equipment like SMT machines.
Typically, the maximal size of general PCB layout is 450x330mm whilst the minimum size is 50x50mm.
You cannot panelize some irregular cellphone PCBs with small sizes, and you will need secondary equipment to aid in fabrication.
What Are The Combination Methods Used In Cell Phone PCB Panelization?
Here are the popular combination techniques applied during panelization of cell phone PCB:
As a common technique, order panelization is the most used method of PCB panelization. There are several advantages that make it the most preferred method.
This panelization method is feasible with all situations, with no regards to SMT assembly and manufacturing conditions.
Additionally, order panelization is not affected by production quantity, allowing the maximal number of panels efficiently depending on maximal number of SMT machines.
Owing to that, it results in the highest production amongst all the combination methods of Panelization.
Order panelization will also not lower the printing quality because of the impact of pad configuration of special components when printing stencil design.
Lastly, there will not be operating challenges because of the different panel orientations in every run of the entire operation.
Order Panelization of PCB
Rotation Angle Panelization
Rotation angle implementation executes the panelization procedure by rotating the panels by 90/180 degrees angle.
This ensures optimal use of the cell phone PCB material and reduce materials wastage.
This panel combination method solves the disadvantages of order panelization by creating adequate space through special components.
After angle rotation, this method improves the mounting efficiency, with the mounted component remaining stable. Further, rotation angle panelization also enhances the effectiveness of fabricators with respect to visual inspection.
Rotation Angle Panelization of Cell Phone PCB
In this combination method, you panelize both sides of the cell phone PCB on a single side of the panel.
It is suitable for circuit boards with no high volume on both sides and does not have components with poor heat resistivity.
Otherwise, parts on the back of weighty and high-volume PCB will probably fall off. Also, poor heat resistivity components will get burned.
One of the advantages of double-side panelization method is that it increases the general efficiency of SMT and reduces fabrication cost.
You can complete the fabrication through one-time operation.
Saving time consumed in product switching and printed stencil, and substantially enhancing SMT machine efficiency.
Moreover, this combination method of panelization does not produce excessive waste. Therefore, the technique is appropriate for mass production of cell phone PCB.
Nevertheless, double-side panelization is not ideal for cell phone circuit boards with BGA because it will result in rework difficulties.
Additionally, the amount of produced boards is limited since you must arrange the panels in even numbers.
Failure to do so will lead to generation of wastes.
This panelization method will also impact DIP utilization rate and plug-in efficiency since you cannot perform DIP and AI until you finish cutting.
Moreover, the technique presents challenges in controlling the quality of cell phone PCB substrate.
Double-side Panelization of PCB
Also referred to as characteristic panelization, combination panelization involves combining different types of cell phone PCB based on combination principle.
This combination method is advantageous in improving fabrication efficiency and cost cutting.
Therefore, it can greatly increase the product turnover, helping in reducing the run time.
Nevertheless, there are also disadvantages of combination panelization.
For instance, it is challenging to manage product differentiation during the assembly line operation, resulting in product chaos.
Furthermore, if a single cell phone PCB amongst the combination experiences a scratch or poor quality, the whole panelization will be scrapped.
The right panel combination technique is dictated by fabrication cost, difficulty, efficiency and depanelizing method.
Snap hole and V-groove are the often-applied methods of depanelization.
Snap holes are commonly employed for cell phone PCBs with thickness lower than 1.0mm and feature external force-sensitive parts like BGA.
This decreases reflow deformation probability, enhancing fabrication efficiency distribute external force and ensure quality.
You must factor pressure during depanelization to prevent deformation because of reflow and guarantee efficient process.
How Do You Reduce Operational Temperatures Of Cell Phone PCB?
Thermal management is a common concern in cell phone PCB design.
Circuit boards having the best thermal design are capable of keeping the whole PCB at steady and even temperature, avowing heat spots.
You can detect potential issues in cell phone PCB thermal management by performing simple design check.
Besides, majority of PCB DRC software are also capable of detecting the problems.
Some of the techniques of thermal management in cell phone PCB design include:
- Connect solid power or ground planes having more layers straight to the PCB heat source.
These planes are generally more capable of dissipating heat because thy incline to consist of more copper.
- Determine efficient high-current and heat paths to aid in directing and dissipating heat. This may assist in optimizing heat transfer.
- Optimize the area utilized for heat transfer, since this can assist in sustaining a reduced temperature throughout the cell phone PCB.
You must consider this early during the design operation, since it can influence the circuit board size.
What Are The Ways Of Improving Pad Off During Maintenance of Cell Phone PCB?
You can avoid neither soldering nor disassembly during cell phone PCB maintenance.
Aging boards or those with very small pads usually experience pod off and solder layer off on the wall of plated hole.
This happens when you disassemble components from the PCB.
- For pin pad off, you can connect it using a short line to the close pad on similar route. Selection of the short line depends on the distance and current amount it can carry.
For short distance, you can use the trimmed scrapped pin header or pins for soldering.
In the case of long distance, use copper wires with external insulating layer for connection.
This helps prevent short circuit due to interconnection between pins and lines of other cell phone PCB components.
- The cause of soldering layer off is the tiny size of plated hole. Thus, the soldering layer of the wall of plated hole come out with the components during disassembly.
Therefore, it is recommended that the pad hole size needs to be 0.3-0.5mm larger in comparison to that of pins.
How Do You Check The Cell Phone PCB Design For Potential Issues?
Inspecting the cell phone PCB design is probably the most crucial stage of the fabrication process.
This phase of the operation evaluates everything concerning the design, searching for potential issues that may jeopardize the PCB design.
In most cases, PCB DRC software helps in carrying out the analysis. Most DRC software can sense nearly all the potential issues in a cell phone circuit board.
DRC software captures all the information about the cell phone PCB design and establishes whether the layout fulfills a checklist of preset variables.
These are referred to as PCB design rules.
Basically, you should apply the DRC throughout the design operation to spot areas with issues early enough.
However, the process of checking cell phone PCB for likely problems does not only comprise of DRC.
It includes various other physical verification procedures such as:
- Electrical Rule Check (ERC)
- XOR Check
- Antenna Check
- Layout-versus-schematic Check (LVS)
More advanced cell phone PCB manufacturers might apply extra rules and checks to enhance yield, though these are the fundamental checks typically employed.
Additionally, it is good practice to confirm fabrication parameters before you submit your PCB design.
Before submission of the final board design for manufacturing, you should generate and confirm the production parameters.
Although most manufacturers will verify the design files on your behalf, it is prudent to double-check the PCB design before sending.
This could aid in avoiding any misunderstanding or confusion and may prevent losses as a result of fabrication with incorrect specifications.
This verification procedure can as well fasten the cell phone PCB manufacturing process.
It does this by reducing amount of time required to resolve and recheck the board design before production begins.
What Are The Benefits Of Using FPC Connectors In Cell Phone PCB Assembly?
Usually, you employ FPC connectors in instances where it is impossible to utilize bigger wire-to-board connectors due to narrow centerline spacing.
This type of connector is beneficial for use in slim cell phone.
The FPC aids you in achieving smaller pitch or centerline spacing, lower profile heights and light interconnect solutions.
Cell Phone PCB FPC Connector
How Do You Solve The Electromagnetic Interference Problem Due To Regular Operation Of Cell Phone PCB Relays?
There will be electromagnetic interference in cell phone PCB caused by relay performance. The EMI will be due to production of arc discharge as the relays cut high current.
These interference affects the normal functioning of the CPU, resulting in regular reset. Moreover, it also makes drivers and decoders to generate incorrect instructions and signals that leads to component implementation error as well.
All these effects will result in defective cell phone PCB.
Therefore, you can apply the following techniques to resolve this issue:
Increase Anti-Interference Ability Of CPU
There is need to install a CPU having high anti-interference ability. You need to perform experiments and tests before choosing the CPU.
The ideal CPUs should have anti-fast pulse, anti-static and electromagnetic capabilities.
Reduce The Source Of Interference
- Relay-driven amplifiers have capacity to effectively reduce the interference produced due to back electromotive force if coil experiences outage.
- Connect RC absorption circuitry parallel in the middle of relay contacts. This ensures rapid quick absorption of noise interference.
- Cell phone PCB are copper clad. The copper cladding is greatly essential in minimizing the electromagnetic interference caused by relays.
- You must carefully select the relays, since those with similar specification usually have options of varying coil power.
The basic concept is that the greater the coil power, the faster the on-off actions of the relay contact.
Thus, shorter arc discharge time between the contacts, leading to shorter electromagnetic interference duration.
Why Should You Use High Frequency Rogers PCB Material In 5G Network Systems?
Rogers PCB material offers many benefits over standard cell phone PCB materials.
Rogers materials not only give high quality circuit boards, they also ensure high performance in challenging applications.
Here are some of the advantages of using high frequency PCB materials in 5G network systems such as cell phones:
- The materials have high impedance stability. This is due to the fact that Rogers PCB laminates have broad dielectric constant range (2.55- 10).
- Rogers PCB substrates also have low dielectric losses.
- In terms of thermal management, high frequency Rogers PCB laminates have great thermal management ability.
- Due to the low dissipation factor, Rogers PCB materials have low signal losses.
- The low moisture absorption feature of Rogers PCB material makes them appropriate for use in 5G network systems in harsh and unstable surroundings. Lower moisture absorption of a material implies greater thermal integrity and electrical characteristcs.
