How to Ensure Reliability in Prototype Assembly

Ensure Reliability in Prototype Assembly

Prototype PCB assembly transforms circuit designs into the first incarnation of an electronic product and is a critical phase in new product development. Getting it right can provide invaluable functional verification and concept validation capabilities. Conversely, a flawed prototype assembly can lead to costly delays in the overall development cycle and project timelines. In fact, the quality of prototyping directly impacts everything from design optimizations to securing financing for production runs. As such, selecting PCB prototype assembly partners that have the technical expertise, on-time delivery records and pricing clarity needed to deliver high-quality yet cost-effective prototyping is essential.

A key aspect of ensuring reliability in prototype assembly is evaluating and deploying a wide array of tools available to the reliability engineer. These range from basic engineering judgment and expert opinion to Physics of Failure (PoF) analysis, simulation models and prior warranty or test data from similar products/components (using Standards Based Reliability Prediction methods).

Another aspect of ensuring reliability in prototype assembly is selecting components that are easily sourced and incorporating the appropriate PCB mounting technologies such as through-hole or surface mount technology. This helps to reduce sourcing and supply chain risks, mitigate component obsolescence concerns and enable quick replacement of any defective components during testing. Moreover, applying good Design for Manufacturability (DfM) principles during the initial PCB layout stages helps to ensure that the circuit board is a good candidate for assembly.

In addition, a thorough review of the bill of materials is crucial to identify any potential issues that can be addressed in early build phases. This is often done in parallel with PoF analysis, which can help to uncover potential problems and prioritize areas for more extensive testing.

When the test results for a particular build come back, the reliability engineer must analyze them and then make any necessary changes in the design. These changes can be in the form of new components, different circuitry or even different placement on the circuit board. This process is typically iterative until the final prototype passes all of the required tests and meets the desired performance parameters.

Once a prototype has passed all the necessary tests, it is ready for mass production. However, in the meantime, it is vital that the team continues to monitor the performance of each unit and take corrective action when necessary. This includes keeping the assembly processes and component suppliers consistent with the original design specification, and performing regular checks for any changes to the component specifications that could affect the reliability of future builds.
