How to Ensure Quality in Automotive PCB Assembly

November 30, 2022

Did you know that the global PCB market will hit over $80 billion by 2026? There have been some concerns recently about the supply chain in circuit boards, but the market is bouncing back, largely due to streamlining PCB assembly quality control.

In automotive PCB assembly, quality assurance is of paramount importance. This is because a single defective component can malfunction an entire system and potentially cause a safety issue.

For this reason, PCB assemblers must take great care to ensure that all components are correctly placed and soldered and that all electrical connections are sound. 

The Importance of Quality Assurance in Automotive PCB Assembly

Quality assurance is a process that helps to ensure that products meet or exceed customer expectations. In the automotive industry, quality assurance is essential for ensuring that vehicles are safe and reliable.

Automotive PCB assembly is a complex process that involves combining hundreds of different parts into a single board. Quality assurance helps to ensure that each board meets the highest standards of quality and performance.

To achieve this, manufacturers must conduct extensive tests at every stage of the assembly process. These tests help to identify any issues that could cause problems down the road.

By catching these problems early, quality assurance helps to prevent them from becoming serious defects. As a result, quality assurance plays a vital role in ensuring the safety and reliability of automotive PCB assemblies.

Checks Performed on Finished Products

In any automotive PCB assembly process, several checks should be performed on the finished products to ensure quality and compliance with standards. These checks can be divided into two broad categories: functional testing and visual inspection.

Functional testing is carried out to ensure that the PCB assembly can perform its intended function. This may involve tests, such as:

  • Power-on testing
  • Electrical continuity testing
  • Signal integrity testing

Visual inspection, on the other hand, is performed to check for physical defects, such as:

  • Missing components
  • Misaligned components
  • Damaged solder joints

Both functional testing and visual inspection are important in ensuring the quality of the final product. However, in some cases, one may be more important than the other.

For example, if the PCB assembly is part of a critical system, functional testing will take priority over visual inspection.

Likewise, if there are concerns about aesthetics or component shortages, the visual inspection will be given greater emphasis. Ultimately, it is up to the assembler to decide which checks are most important for each particular product.

However, at Geospace, we go above and beyond and perform X-ray inspections on all our automotive PCB assemblies. This helps us detect any hidden defects that may not be visible to the naked eye.

Common Problems that Can Occur During PCB Assembly

PCB assembly is a complex process that requires care and precision at every stage. Unfortunately, several common problems can occur, which can lead to faulty or damaged boards.

One of the most frequent issues is component misalignment, which can happen when components are not correctly placed on the board or when the solder paste is not properly applied.

Another common problem is bridging, which occurs when the solder connects two adjacent conductors, creating a short circuit.

Bridging can be caused by:

  • Poor stencil design
  • Incorrect component placement
  • Excessive solder paste

Excessively large or small solder joints can also be an issue, as can cold or hot solders. These problems can all be avoided with careful planning and attention to detail during the PCB assembly process.

How to Reduce Costs and Risks with PCB-A

Assembling a printed circuit board (PCB) is a complex and delicate task that requires a high degree of accuracy and precision. The slightest mistake can result in a defective board, which can be costly and time-consuming to fix.

One way to reduce the risk of errors is to use an automated assembly process. This technology uses robotic arms to place components on the PCB, eliminating the need for human intervention.

In addition, automated assembly lines are typically faster than manual assembly, meaning that turnaround time can be reduced.

Finally, using automation can also help to lower costs as it reduces the number of workers required and minimizes the chances of defects. Overall, automating the PCB assembly process effectively reduces costs, risks, and turnaround time.
