What Are The Different Types Of Battery Charger PCBs Available?

Battery charger PCBs can be made in various forms to suit various applications. The type of PCB to build will require you to determine the use for which it is intended, desired dimensions, and power requirements.

The following are the most common types of PCBs available and an appropriate build is picked depending on the user requirements:

Single-sided PCBs

Here, the battery charger PCB is built out of a single layer of a substrate and a thin layer of a metal. All the components of the circuit are mounted on one side of the board.

Double-sided PCBs

A layer of conductive material is applied on both sides of the substrate material in this type of PCB. A hole may be drilled at the center of the board to allow connections to both sides.

Multilayer PCBs

These are made of three or more double layered PCBs glued together using specialized adhesives.

Flexible PCBs

These are PCBs made up of flexible substrates to enable customization into shapes that are suitable for the intended purpose. The technology is applicable in single, double, and multilayered PCB types.

Rigid PCBs

Used in battery charger applications that keep their shape throughout their lifetime. They are made from rugged substrates that cannot be twisted.

Rigid-flex PCBs

This type integrates both rigid and flexible technologies. It helps in conserving space as flexible and rigid connection methods can be employed on the same board.

Aluminum Backed PCBs

Aluminum is used as a substrate instead of fiberglass in these types of PCBs. They are normally preferred for high-power PCB electronics.

How Do You Choose The Best Battery Charger PCB?

To get value for your money, it is advisable to do due diligence to choose the best manufacturer. Choosing the right company for your battery charger PCBs can sometimes be very challenging.

The following six factors will guide you in settling on the right manufacturer for your battery charger PCB needs:

Product Quality

Just like in buying any item, quality is a very important aspect to think about when looking for the best battery charger PCB. Quality can be assured by monitoring every stage and aspect of development of the PCBs.

You can ensure quality by seeking reviews on suppliers, work in progress (WIP) inspection, outgoing inspection, and customer service.

PCB Price

The right battery charger PCB to go for may also be determined by price. PCB prices vary with quality and design.

Factors such as the kind of substrate used or the solder material used will definitely influence a PCB’s price. Therefore, you have to weigh your budget against product quality as you make decisions on the right PCBs to settle for.

PCB Manufacturing Speed

Projects have deadlines and your manufacturer must be able to produce and deliver your battery charger PCBs within stipulated timelines.  It’s is therefore important to consider turnaround and delivery schedules while choosing your manufacturer.

It is easy to get lured by competitive prices at the expense of delivery schedules. For that matter, it is imperative to watch out on that.

Minimum Order Quantity (MOQ)

Different suppliers operate at different order benchmarks. It is of essence that you choose the manufacture who is able to deliver your minimum order requirements.

Customization Options

There is no one PCB product that can serve all imaginable user requirements. Various specifications are designed to serve various purposes.

It will serve you better engaging a vendor who can customize your battery charger PCBs to suit your needs. A supplier with experience in the battery charger industry would be the best bet.

Customer Support

A good vendor should have a comprehensive customer support system from assembly to use of the PCBs. Choose a manufacturer with a professional customer service team that is constantly in touch with you and promptly attends to your feedback.

What Are The Components Of A Battery Charger PCB And What Are Their Functions?

A battery charge circuit board is made up of the electrical components such as transistors, diodes, capacitors, resistors, and sensors.

These components are vital to the functionality of the charger.

Each of the components serves a particular purpose and the charger will fail to work if one of the components fails to work. The components include:

Battery Charger PCB Components

Battery Charger PCB Components


Are vital components that allow current to flow through them as it produces voltage and dissipates power in form of heat.

Resistors can be made from different materials and have color codes to indicate resistance value.


Transistors are basically amplifiers that function as switches in a circuit board to control signals.

There are a variety of transistors but the most common ones are the bipolar transistors.

The bipolar transistor is made up of three pins that are the collector, emitter, and the base.


Capacitors are common in battery charger printed circuit boards just like resistors.  Their function is to store electric charge and release it whenever it is needed in the board.

Capacitors store by trapping opposite charges in between two conductive layers that are separated by an insulating material in between them.


They also store energy like capacitors though in the form of magnetic field as electric current flows through them.

Their purpose in the circuit board is to block signals such as interference coming from other devices.


Transformers are used to step up or down voltage as electrical energy is transferred from one circuit to another in the board.


A diode is an electrical component that allows current to flow only in one direction in a circuit. It is used to prevent current from flowing in the wrong direction that could cause damages to the battery charger PCB.


These are devices that detect environmental changes then generate signals corresponding to those changes.

The generated signal is then relayed to the other components of the circuit for action.

How Does A Battery Charger PCB Work?

The battery charger PCB holds electrical components such as resistors, capacitors, and diodes in place.

Electrical pathways are etched either on a fiberglass or on a laminate material.

Copper lines provide the path for charges to move while powering the various components.  The copper lines can be viewed as electric cables that provide the path for current to flow in a particular direction to power a device.

Which Are Different Battery Charger PCB Material?

The four main parts of a PCB unit are substrate, laminates, solder mask, and silkscreen.

The substrate is the frame on which all the components of the PCB are mounted.

The laminate is the material that glues together the layers of the PCB while the solder mask protects connections from environmental effects.

The silkscreen fastens to the solder thus enabling labeling of components.

The materials listed below are some of the most common materials used in manufacturing of battery charger PCBs:


FR-4 material is commonly referred to as fiberglass and it is water and fire resistant. It is preferred in the manufacturing of boards because it offers high tensile strength in lightweight packages.


These are Teflon laminates that are suitable for high speed circuitry.

PTFEs are flexible, strong, and adaptable to both cold and hot conditions making them suitable for constructing high frequency PCBs.


It is a good conductor of electricity thus is good for current flow in a circuit board. Other metals that are also used are aluminum and iron.

Are Battery Charger PCB Materials Flame Retardant?

Flammability is one of the factors considered when selecting battery charger PCB materials. FR-4 is mostly used as the base material in the manufacture of PCBs.

Battery charger PCBs base materials are made using flame retardant chemicals so as to ensure fire safety.

The FR in FR-4 is an acronym for Flame Retardant which means the material is self-extinguishing in case of fire.

FR-4 is internationally accepted for fiberglass reinforced epoxy laminates. It is composed of bromine and that’s what makes it flame retardant.

What Is The Voltage Output of Battery Charge PCB?

The output voltage of a battery charger PCB varies depending on the design specifications. The output could be 5V, 12V, 24V, or even 48V.

How Does Hole-Mounting And Surface-Mounting Of Battery Charger PCB Components Compare?

In a through-hole mounting configuration, leads run from both sides of a PCB through drilled holes. Fastening the leads through the holes results in a mechanically strong battery charger PCBs.

In surface mounting, on the other hand, all electrical components are mounted on the surface of a PCB.

The surface mounting technology is less expensive in comparison to the through-hole mounting because no drilling is needed.

The surface mounted PCBs are also smaller in size and operate at higher electrical capacities.

What Are The Battery Charger PCB Sizing Options Available?

There is no limit to the sizing options of battery charger PCBs. There is no single PCB that can provide all the battery charging solutions one might require.

Power requirements, the thickness, and shape of battery charger determine the shape of a PCB that is assembled for a particular solution.

There is no existing industry standard for the thickness of a battery charger PCB but most of them are around 0.062 inches thick.

How Does USB-A And USB-C Components Of Battery Charger PCB Compare?

USBs can be categorized into USB- A or USB-C depending on the physical design of their ports and connectors.

Type A is the most common type of USB standard. They are mostly found in host devices such as computers and game consoles.

Type C, on the other hand, are the industry standard connectors that are used to transmit both power and data on a single cable.

Which Are The Acceptable Files Formats For Battery Charger PCB Design?

  • ODB++ (.tgz)
  • Adobe Acrobat (.pdf)
  • AutoCAD (.dwg or .dxf)
  • HPGL (.hpg, .gif, .tif etc)
  • Graphic file
  • Readme files (.doc, .txt)

Can You Repair A Battery Charger PCB?

Just like other items, battery charger PCBs also deteriorate over time as they are used and might need to be repaired.

Physical Damage

Physical damage can be corrected through a re-manufacturing process.

Re-manufacturing can be achieved by melting down the damaged parts of the board or simply through disassembly and reassembly.

The nature of physical damage makes it quite difficult to fix as a DIY project by those not skilled at repairing PCBs.

The repair should be done by an expert.

Repair physical damage mostly involves remodeling the board, soldering its components afresh, and redoing conductive traces.

Component Failure

Component failure should also be best left to professionals to fix.

Voltage tools and other measuring devices can be used to test the conductivity of various circuits of the board.

The tools can be used to find out if electricity is flowing through a component or if it has failed completely. A component that has died has to be replaced.

Trace Damage

Traces are the conductive pathways made of copper or silver. Repairing a damaged pathway is done by simply reo-soldering with the right material.

Poor Design

Poorly designed boards fail frequently.  The best solution to a poorly designed board is to just replace it.

Power Failure

The repair here should also be best left for professionals but it generally involves replacing or resetting power supply components.

How Do You Troubleshoot A Battery Charger PCB?

Some of the ways of troubleshooting common problems in battery charger PCB include:

Physical Damage

Physical damage on battery charger PCB can easily be noticed just by inspecting the board to note any kind of deformation in it.

Component Failure

Component failure can be diagnosed with the help of measuring devices like multi-meters to establish if current flows through the components or not.

The components that don’t conduct are faulty.

It’s also possible to note the failed components upon opening the battery charger PCB module. They will be, in most, cases burnt, cracked, or loosely attached to the board.

Trace Damage

Damages on the trace can simply be identified by scanning the pathway so long as the trace is not too thin to see with naked eyes.

Copper or silver are shinny and it is possible to establish if there’s a break on the path.

Poor Design

A poorly designed battery charger PCB will continue to fail even after repair.

Power Failure

Just like other non-visible damages, power or voltage meters are used to diagnose power related failures in battery charger PCBs.

What Are The Factors Affecting The Battery Charger PCB Cost?

The cost of a battery charger PCB is dependent on the cost of assembly. A high cost of assembly translates to a high cost of the PCB and vice versa.

The factors determining the cost of assembly are:

Circuit Board Size And Number Of Layers

A large circuit board will need more materials to assemble a battery charge PCB resulting in higher cost. The reverse is true.

Mounting Technology

Through-hole technology is more expensive than surface mounting because more labor and time is required to drill holes.

Order Lead Times

Orders that take long to deliver directly impact on cost. You can cut on cost by initiating your PCB assembly process in advance so that you have them ready when you need them.

It is also advisable to go for a manufacturer with good reviews on delivering in time.

Order Quantity

Buying in bulk is always cost effective. It is advisable to plan your battery charger PCB needs and buy all at once instead of buying in batches throughout the year.

Is It Possible To Update Old Battery Charger PCBs?

Updating an old PCB is a cost-effective way of making changes to an already installed battery charging system.

Engage an expert to make the changes to guarantee safety and desired results.

An example where an update would be necessary is when you want to acquire a new equipment with different power requirements.

What Is The Maximum Input And Output Current Of Battery Charger PCB?

Just like with voltage, there’s no fixed maximum output current for a battery charger PCB. The maximum output current of a particular battery charger PCB is dependent on its design capabilities.

Can Battery Charger PCBs Be Recycled?

Battery charger PCBs that are no longer in use can be stripped of parts for use in other applications.

It is not advisable to trash outdated PCBs so that they end up in landfills.

Components such as resistors, capacitors, inductors, and the rest can be extracted for use in future projects thus cutting cost.

The components should be carefully extracted using specialized tools to avoid damaging them.

The copper elements of the board can also be put to other uses.  Certain organizations can recast recyclable parts of a battery charger PCB to make something new.

What Is The Average Lifetime Of A Battery Charger PCB Assembly?

It is not quite possible to tell how long a battery charger PCB will take before it wears out.

The modern PCB designs have, however, taken into account thermal and mechanical reliability of the PCBs to make them as long-lasting as possible.

Battery Charger PCB Assembly

Battery Charger PCB Assembly

Battery charger PCB can be usable for around 50-70 years.

This applies so long as the environmental conditions remain favorable and the manufacturerer’s conditions of use are observed.

The lifespan of the board is of course different from other components such as transistors. Factors determining the lifetime of a battery charger PCB are the size the PCB, their type, and the conditions in which they operate.

Transistors in the PCBs are quite a miracle – they don’t easily burn out.

They may wear out eventually, though, after long-term exposure to environmental elements that make them die gradually.

How Long Does It Take To Assemble A Battery Charger PCB?

The lead-time for a charger PCB ranges between 3 – 14 business days (exclusive of delays) depending on the customer order requirements.

Lead-time means the time taken to deliver a client’s PCBs right from when they place orders to the time when they are dispatched.

It takes shorter time to assemble a battery charger PCB if all the components are found in one place.

The assembly quantity may also determine the lead-time.

It is advisable that one places their orders in advance of their deadlines.

This is particularly important just in case there might be unforeseen delays that may lead to more waiting time.

What Are The Applications Of Battery Charger PCB?

Battery charger PCBs can be used anywhere there is battery charging system to protect batteries from overcharging, over-discharging, or over-draining.

Some of the areas where battery charger PCBs find use include:

  • Automotive industries: flexible battery charger PCBs are integrated into car system to note changes in temperature and also to check car battery charging system.
  • medical facilities
  • power generation plants, industries, and
  • Any other place with battery banks being used as primary or secondary sources of power.

Can You Manufacture Automatic Battery Charger PCB?

It is possible to make an automatic battery charger PCB. For instance, an auto cut-off charger can be made on a zero PCB for charging a 6V or 12V battery.

Charging automatically stops when voltage crosses the pre-set cut off voltage.

Basically, the steps for making an automatic charger PCB can be broken into the steps below:

  1. Mark the automatic charger layout on the board
  2. Drill holes for all the circuit components as shown on the layout
  3. Mount the components as they appear on the layout
  4. Go ahead and solder the components on the board
  5. The automatic battery charger PCB is now ready. You can proceed and set the cut-off voltage

How Do You Set The Cut-Off Voltage In Automatic Battery Charger PCB?

To set cut-off voltage for an automatic battery charger PCB, a variable DC power supply is connected at DC input of circuit board.

A multi-meter is also connected on the battery side at the same time.

If, for instance, you would like to set a cut-off of 12V then you have to apply 12V voltage at the DC input.
