PCBA functional testing refers to the quality verification step performed after the parts have been assembled on the PCB and after other testing have been done already. It provides assessment by subjecting the PCB to a simulation test of the environment of the final PCB product through application of input signals and measuring how the PCB behaves. This step helps to check if the PCB passes the reliability requirements.
The PCBA test engineer provides the test plan and Design for Test (DFT) to determine the right sets of test methods and parameters to apply. He or she works closely with Hardware engineers to develop the test fixtures and deploy the test systems.
The types of PCBA test equipment used in functional testing can be grouped according to the type of fixtures, instrumentation and software categories and test scope. The test equipment can be made of a fixture or bed-of-nails or of a more customized solution such as contact or flying probes.
Yes, we do. As we know that requirements are highly varied, we develop customized PCBA test solutions that follow a structured validation approach to ensure that the PCBA are tested according to specifications. We collaborate with our customers to discuss the test strategy and review the data to optimize quality and productivity.
The PCBA functional test software is the central control system of the PCBA that enables automation and data collection. The test software dictates the test sequence, input stimuli and measurements. Most software programs used in functional testers include LabVIEW which utilizes C++ or Python programming languages.
The functional tester in PCBA testing is an integrated system consisting of test fixture, instrumentations and software system. These parts work together to mimic the final operating environment by contacting the PCBA test points, applying input signals and collecting and measuring the response. It is required to confirm the system-level functionality and reliability before shipping to the customer.
PCBA testing is different from PCB testing as PCBA testing is done after all components have been assembled already while PCB testing is done after bare circuit board fabrication. The main goal in PCBA testing is to verify the final circuit function and check any assembly issues.
