How Do You Manufacture Car PCBs?

 Below Are The Steps To Consider During Manufacture Of Car PCB

Below Are The Steps To Consider During Manufacture Of Car PCB

Below are the steps that you will follow when manufacturing car PCBs:


The first phase is designing the car PCB blueprint using software to ensure it has no errors or flaws.

Manufacturers receive the prototype and conduct Design for Manufacture checks to ensure everything is in order.

Printing The Design

Here, the manufacturer will print the car PCB design using plotter printers that develop the car PCB film.

Besides, each film represents a layer of the car PCB then you will punch registration holes in them as a guide.

Print Copper Layers

The manufacturer will pre-bond copper on laminate material to assist with the car PCB structure.

Copper is imprinted out to show the former blueprint design.

Afterward, you will cover the laminate with a resist, a photo-sensitive film, which hardens once you expose them to UV light.

Then you will pressure-wash the board to eliminate surplus photo resist sing alkaline solutions.

Remove Unwanted Copper

The manufacturer removes surplus copper using chemicals that eliminate copper that has no photoresist cover.


Here, you will align the holes of the car PCB using an optical punch system.

Afterward, another system conducts an optical inspection to ensure there are no flaws on the car PCB.

For instance, you can use an automated optical inspection to compare the car PCB to the Gerber file design.


The manufacturer will fuse different layers once they pass the inspection phase.

Besides, the lamination process can happen through lay-up and laminating steps.


An X-ray system locates the locations where you will conduct the drilling process.

Also, you will drill registration holes to protect car PCB stacks before conducting precision drilling.


This entails using chemicals to bind all the car PCB layers together.

Then you will dip the PCB through chemicals to coat it with a micro-thick copper layer.


Here, you will apply another photoresist layer on the external layer of the car PCB, then conduct imaging.

Besides, you will use tin to plate the external layer to protect the copper layer.


A tin guard protects the copper layer when you are etching the external layers.

Solder Mask Application

This entails applying epoxy with a solder mask then exposing it to UV light.

Afterward, you will eliminate the surplus solder mask then place the car PCB in an oven to cure the solder mask.

Surface Finish

This entails plating the car PCB with gold, silver, etc. to protect the copper, then conducting silk screening.

During silk screening, you will imprint information on the car PCB.

The information includes warning marks, company identification, manufacturer labels, etc.

Electrical Test

Technicians conduct a series of electrical tests to ensure the car PCB is operational.


Here, you will cut and score the car PCB from the main panel.

Besides, you can cut the car PCB using V-grooves or CNC or router equipment.

They will relay the ignition effect to the engine hence power on the car.

Battery Control System PCB

Car PCBs will relay information regarding the battery and its charge status, which is useful in avoiding the car not turning on.

Transmission Sensors PCB

With automatic cars, the gear system automatically shifts with the angle of terrain and the speed of the car.

Car PCBs assist in transmitting this information to the transmission sensors that will upshift or downshift the gear.

Electronic Mirrors PCB

Unlike traditional mirrors where you had to manually adjust the mirror angle, modern cars allow you to automatically adjust them using buttons.

Car PCBs assist in transmitting the information between the mirrors and control knobs for easy adjustment even when driving.

Antilock Braking System PCB

This feature prevents the car from skidding when you hit on the brakes too hard, hence keeping you and others safe.

Car Sensor System PCB

This feature in car PCBs allows you to detect if you are too close to other cars when driving or parking, hence, increasing safety.

Also, the car PCB manufacturers have to comply with ISO/TS 16949 which finds its establishment from ISO 9001 automotive quality.

How Does Surface Mounting And Thru-Hole Mounting In Car PCBs Compare?

Here is how these two compare:

Thru-hole Mounting

In this process, you will place the component leads directly into pre-drilled holes within the bare car PCB.

This process forms a strong connection than its surface mount counterpart making them suitable in applications requiring more reliability.

The lead will run through the board and does not attach to the surface like in surface mounting.

Besides, thru-hole mounting is suitable for prototyping and testing usages that need you to manually adjust the parts.

Surface Mounting

In this process, you will directly mount the components directly on the surface of the car PCB.

Besides, it uses small parts known as vias to connect several layers within the car PCB.

Also, you can attach components on both sides of the car PCB, enabling you to fit more parts on the board.

This feature will lower costs enabling you to manufacture compact electronic systems.

Surface mounting is also faster than thru-hole mounting, hence, reducing the cost further.

 How Will Electric Cars Affect Car PCB Industry?

As the world moves towards electric-powered cars, car PCBs will be vital in producing and operating these cars, buses, or other automobiles.

For instance, we anticipate the rise of chargers.

Also, with the technological advancement in driverless cars, anticipate seeing more car PCBs finding their application in the automotive industry.

This entails both designing and manufacturing cars.

According to the law of economics, an increase in demand for car PCBs will lower the cost of printed circuit boards and components.

This is because the increase in demand will increase the opportunity for different companies to use the economy of scale to their advantage.

Also, there will be an increase in demand for copper due to the increase in electric cars.

Also, place routing in a straight and short track.

Order And Separate Parts

Begin by placing larger parts, then smaller electronic components.

Also, place analog or mixed parts in dedicated locations away from digital parts.

Besides, take into consideration the height of the components by not placing tall parts near short parts to maintain viewing angle.

Thermal Management

This entails identifying parts that release a lot of heat and checking the thermal resistance rating on the datasheets.

Suitable thermal management occurs when the whole car PCB has a similar temperature level.

Besides, you can use copper traces and thermal vias to enhance thermal conductivity.

Also, ensure you distribute heat evenly to avoid hot spots that may impact the performance of the car PCB.

DRC Regulations

This stands for Design Rule Check.

Its main purpose is to:

  1. Identify flaws that fail to match the main manufacturing parameters
  2. Locate high-speed electrical parameters
  3. Identify other parameters for your application

It is important to conduct DRC in the entire design process and not just at the final stage.

This assists in identifying mistakes and rectifying them early.

Also, you will connect the wire filling terminals using a thru-hole to the ground.

Finally, you will connect lines of coated copper to the ground.

All these will ensure you have a functional car PCB.

Lead Coupling

Placing leads closer together will affect coupling and cause mutual inductance.

It is therefore important to place return current paths closer to main current paths in a small field of radiation.

This will lower the current loop area.

Besides, you can integrate grounding below the leads to enhance the performance of car PCBs.

Thru-hole Grounding

This entails having inductance modules in sensitive regions for thru-hole and the matching network should rely on independent thru-holes.
