What are the Advantages of Blue PCB vs. Green PCB?

The main benefits of blue PCB are:

  • The contrast between the screen print and solder mask is high in blue PCB. Therefore, it is a suitable choice if the color PCB contains many part numbers.
  • It is easier to see the dirt on a blue PCB than on a green PCB. This is because the blue color is not as clear as the green PCB.
  • Also, a blue PCB is more appealing than a green PCB.

Which are the Key Blue PCB Material Properties to look for?

The primary properties of Blue PCB to consider include:

Mechanical Properties

  • Bending Strength

This is the capability of the PCB to resist breakage or deformation when it is under stress.

  • Density

This is the amount of mass for every volume for a dielectric.

  • Peel Strength

It is the ability of the copper layers and the dielectrics to remain bonded when under chemical and thermal stress.

  • Time to Delamination

This is the measure of the duration the blue PCB layers will remain together when you expose them to temperature and moisture.

Electrical Properties

  • Dielectric Constant

It will influence the integrity and impedance of the blue PCB material. Also, it should have a constant value over broad frequencies, especially in high-speed applications.

  • Surface Resistivity

This is the measure of the resistance of the dielectric material’s surface to electricity flow. Since it is prone to temperature and moisture, it should be high to ensure the integrity of a good signal.

  • Volume Resistivity

This is how you will measure the dielectric’s volume resistance. It needs to be high to maintain the isolation that is between the layers.

  • Dissipation Factor

This is how you will measure the power loss of the blue PCB material. It is vital for analog frequencies that are above 1GH since the dissipation factor will increase when the frequency increases.

  • Electrical Strength

This is how the blue PCB will resist electrical breakdown specifically in the z-direction.

Thermal Properties

  • Glass Transition Temperature

This is the temperature where the substrate of the blue PCB reversibly changes from hard to soft. Also, it has to be lower than the temperature of the solder.

  • Decomposition Temperature

This is the temperature at which the substrate of the blue PCB permanently decomposes. Besides, it should be lower than the temperature of the solder.

  • Coefficient of Thermal Expansion

This is how the blue PCB expands when you expose it to heat and it should be as low as can be.

  • Thermal Conductivity

This is the rate at which heat will move within the blue PCB material. It should be low for insulators and high for conductors.

Chemical Properties

  • Methylene Chloride Resistance

It highlights the percentage of the volatile toxic solvent, methylene chloride, that you will use in the production of blue PCB. Typically, it should be less or equal to 0.2% for dielectrics.

  • Water Absorption

It highlights the amount of moisture that the blue PCB material will absorb when you submerge it. The value for most materials is under 0.2%.

It may affect the thermal and electrical properties of the dielectric.

  • Combustibility

This is how long the PCB material may burn when under combustion. The time for blue PCB material should be at 10 seconds for every specimen.

Also, this is a standard under the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances.

What are the Steps of Designing Blue PCB?

Here are the designing steps for Blue PCB:

  • An electronic design automation equipment will capture the schematics.
  • The circuitry and the case of the blue PCB will determine the size and template.
  • Next, you determine the position of the heat sinks and the parts of the blue PCB.
  • After that, you decides the layer stacks of the blue PCB depending on its complexity.
  • Next, determine the line impedance by use of trace-width, the thickness of dielectric layers, and routing copper thickness.
  • Place the components together while taking into account thermal properties and geometry.
  • Then, mark the lands and vias.
  • Route the signal traces then generate the files for manufacturing.

Is Panelization of Blue PCB Possible?

Yes, this is possible. You can combine many small blue PCBs for processing as a panel.

For instance, when you duplicate a design 5 times, it is known as a 5-panel. A multi-panel will combine many different designs to form one panel.

What is the Function of Blue PCB Transmission Line?

These are interconnections whose function is to move signals from blue PCB transmitters to receivers. Every transmission line has a minimum of two conductors.

One conductor is a signal trace and every transmission line should have at least a single return path. A majority of the return paths are usually ground planes.

The blue PCB material will make up a large chunk of the conductors. Also, dielectric layers separate signal trace from ground planes together with other conductors.

Which are the Types of Blue PCB Transmission Lines?

The two transmission lines for Blue PCB include:


Blue PCBs with striplines have uniform trace for signals on the inner layers of the circuit board. The trace and the conducting planes have a parallel blue PSC dielectric layer that separates them.

Also, the conducting planes will act as return paths. Besides, the other ground plane will allow for thin and controlled impedance traces.

A small trace width will increase the density thus stripline transmission lines work well with tight and compact designs. The internal layers of the striplines will offer a reduction of electromagnetic interference [EMI] and protection against hazards.

Microstrip Line

Here, you will find the single uniform trace on the outer layer of the blue PCB. Also, the return path of ground plane conductors is parallel to the trace.

A PCB dielectric will separate the ground planes from the trace. Besides, the layer stricture of microstrip lines is simple thus lowering the production costs.

Differential microstrip lines are pairs of microstrip lines that carry balanced signals and can carry high-speed signals.

Which are the Blue PCB Transmission Lines that Need Controlled Impedance?

Other distinctions exist between transmission lines besides the distinction between stripline and microstrip line. An embedded microstrip is built, for instance, by implanting the visible trace of a microstrip line within the dielectric layer.

Another typical modification is the separation of PCB transmission lines into differential pairs.

A differential pair, like transmission lines, is a stable pair of conductors. These pairs exchange energy and are affected by impedance.

The following blue PCB transmission lines will need a controlled impedance:

  • Single-Ended Microstrip
  • Differential Pairs of The Microstrip
  • Embedded Microstrip
  • Single-Ended Stripline
  • Differential Pairs of The Stripline
  • Single-Ended Co-Planar Waveguides
  • Differential Pairs of the Coplanar Waveguides

How do you Determine the Blue PCB Impedance?

Impedance will assess the opposition when you apply an alternating current to an electric circuit. It is a combination of the induction of electric circuits and capacitance at high frequencies.

Here are some factors that will determine impedance on blue PCB:

  • The thickness and width of the copper trace.
  • How the signals pass through the vias.
  • The thickness of the core or the thickness of the prepreg substance on either side of the trace.
  • Dielectric constant of the prepreg material and the core.
  • The distance from the copper plane source.
  • Also, the availability or unavailability of the solder resist.

Why Should you Control Impedance of Blue PCB?

Impedance control entails calculating the impedance of specific traces during color PCB manufacturing and ensuring that it is within the designer’s limits.

Where a signal needs a certain impedance to function correctly, you should use controlled impedance.

Maintaining constant impedance around the entire electronic board is critical.

This is especially vital in high-frequency applications to secure the transmission of data and ensure signal visibility.

The broader the trace or the greater the frequency, the higher the need for adaptation.

Any laxity at this point will lengthen the switching time of an electronic system or circuit and lead to accidental errors.

After the installation of the parts on the circuit, uncontrolled impedance is challenging to analyze. Depending on the batch, components have varying resistance capacities.

Moreover, temperature fluctuations have an effect on their parameters, which leads to system failures. In such situations, replacing the part may appear to be the remedy at first.

However, it is the unsuitable trace impedance that is causing the issue.

As a result, trace impedances and tolerance levels must be evaluated earlier in the PCB development process.

Designers and manufacturers must collaborate to ensure that component principle are consistent.

When is Blue PCB Impedance Most Important?

This is evident when you need quicker processing and the use of less energy.

It is vital when you require the blue PCB to perform the best over time, improve the value, and control reliability.

Controlled impedance is necessary when transitioning from a low Ohm to a high Ohm condition where the impedance is available.

Energy reflection in the form of strong pulses capable of disrupting energy flow may result from these types of transitions.

This is an issue for those who manufacture high-powered digital systems and radio frequency (RF) applications.

What are the Copper Patterning Techniques Applied During Blue PCB Manufacturing?

The methods of Copper Pattern in Blue PCB include:

Silkscreen Printing

This process makes use of etch-resistant ink to form a protective mask.


This technique will use photomasks and developers to eliminate a UV-sensitive photoresist coating selectively. It does this to protect the copper below by creating a photoresist mask.

For high-resolution needs, you can use direct imaging methods.

PCB Milling

This system applies two or three-milling systems to remove copper foil away from the substrate mechanically. It gets commands from the software which controls the milling head position on all axis.

Laser Resist Ablation

It begins by spraying black paint on the copper laminate clad then place it inside the CNC laser plotter. The laser will raster-scan the blue PCB and vaporize the paint in areas that need no resist.

Laser Etching

You can directly remove the copper using a CNC laser. Also, laser etching is applicable for prototyping.

How do you Drill Blue PCB Vias?

The following steps will guide you on how to drill vias/holes in blue PCB:

  1. Using clamps, secure the PCB to the drill machine surface.
  2. Be certain that it is securely fastened.
  • Insert a drill bit into the drill machine and place it on top of the first via on the blue PCB.
  1. Position the drill bit on top of the via and in the center of its pad.
  2. Put on your protective glasses and earmuffs.
  3. Switch on the drill machine and lower it slowly using the lever until the drill bit emerges from the opposite side of the board.
  • As the drill spins, slowly retract it upwards and turn it off once it reaches its nominal location.
  • Drill all via holes in the very same manner and remove the board when done.

Blue PCB with Blind Vias

 Blue PCB with Blind Vias

What Are the Uses of Vias in Blue PCB Design?

The common application of blue PCB vias are:

Signal Routing

Most blue PCB uses thru-hole vias to route signals on grids. Dense boards may need buried or blind vias with microvias for very dense boards.

Escape Routing

You can use an escape routing that has a thru-hole via for large surface mounts.

Also, you may consider microvias or blind vias on dense packages.

Power Routing

Vias for power and ground nets conduct more current thus use larger thru-hole vias or even a blind via.

Stitching Vias

They offer several connections to a plane and therefore are either a thru-hole or blind vias. For instance, you may surround a sensitive area with metal strips with stitched vias to connect ground planes.

This provides EMI protection.

Thermal Vias

This functions by conducting heat away from out of a component via the internal plane layers which connect it. They require large thru-holes or blind via.

Besides, these vias are in the pads of the devices.

Why are Microvias the Best for High-Density Interconnection (HDI) Blue PCB?

This is because they have a smaller diameter and their depth can go up to two layers deep. Also, the smaller diameter achieves a higher throw power of the plating bath thus enabling an electroless copper plating.

Which are the Different Types of Microvias you can Apply in Blue PCB?

Some of the most common options you can consider during PCB fabrication include:

Staggered Vias

These scatter in different layers and are also expensive.

Stacked Vias

These will pile one on top of the other in various layers.

Skip Vias

They skip one layer thus pass through a layer without making any electrical contact with it. Besides, they will not form an electric connection using that via.

What are some of the Tips to Consider when Drilling Via in Blue PCB Design?

Whenever you’re drilling blue PCB, you should consider the following:

  • Keeping the aspect ratio to a minimum for better signal integrity and electrical performance.
  • Fill via-in-pads unless they are within thermal pads.
  • Select maximum micro via in the design structure.
  • Choose staggered vias since stacked vias need fillings and planarization.
  • Confirm minimum trace clearance and vias from routed edges.
  • Use vias in thermal pads under QFNs to assist the solder flow to the conductive planes.

Which are the Important PCB Design Guidelines to Consider During Blue PCB Component Placement?

At times components placement on blue PCBs can be a challenging process.

But as you handle the process, it is important to take note of the following:

  • Fine-tuning the placement of the component.
  • Placement of power, signal, and ground traces.
  • Keeping things separate.
  • Solving heating issues.
  • Confirming the layout against the blue PCB design parameters.

Which are the Available and Useful Blue PCB Routing Tools?

When it comes to blue PCB routing, you can consider any of the following tools:

  • Manual interactive routing
  • Slide routing
  • Fanout routing
  • Differential pair routing
  • Bus routing
  • Auto-routing
  • Trace tuning
  • Cleanup routing

How do you Control Signal Interference in Blue PCB?

You can eliminate such interference through:

  • Placing solid reference plane next to signal traces to monitor crosstalk.
  • Controlling ringing by use of terminations.
  • Creating a constant trace impedance by controlling the spacing of trace width to reference planes.
  • Reducing crosstalk by increasing spacing between traces.

What are some of the Challenges during Blue PCB Routing?

Some of the most common challenges during routing are:

  • Short design times
  • Several design constraints
  • Analysis expectations
  • Complex routing requirements

How do you Perform Bare-board Testing of Blue PCB?

You can use one of the following methods to perform this test:

Pinned Fixture Test

Here, a spring-loaded pogo will test all the connective surfaces at one go. Upper and lower plates will apply pressure to a pin fixture to ensure there is a connection across the entire PCB.

You can use this method to test several points concurrently thus it is more efficient than flying probe testing. Besides, it takes almost five seconds to complete the test.

Flying Probe Test

This test involves the use of two robotic arms that have poles that verify the connections of a blue PCB.

They fly across the connection using commands from software.

Besides, this test will achieve better affordability and flexibility when you compare it to pinned fixture test. It is suitable for small productions in which slow testing will not interfere with design processes.

What are the Ways of Testing Blue PCB Assembly?

You can test the board in several ways:

  • Visual inspection
  • Automated optical inspection
  • Analog signature analysis
  • Power-off testing
  • In-circuit testing
  • Functional testing
