Effective test methods for printed circuit board assembly

When you consider ordering printed circuit board components, be aware of the expensive consequences associated with PCB failure. The last thing you want to check is that PCBs are dropped without warning-or their lifespan is shortened due to design or QA issues. The PCB board assembly test method is an integral part of the manufacturing process.

Bare board test

Bare board testing refers to a PCB manufacturing company testing the continuity and isolation of electrical connections on an empty PCB before connecting important components such as ICs. Continuity PCB testing involves verification to ensure that there are no open points in the circuit. On the other hand, perform an isolation test to ensure that you meet the required resistance between the two separate electrical connections. The idea behind bare board testing is to ensure that the PCB circuit is partially correct. Bare board testing is particularly important because it can save the manufacturing company money and time, thereby avoiding repairs, field testing and maintenance costs.

Assembly level test

For PCB board assembly, assembly level testing is crucial. After the meeting, assembly-level testing is essential to check the function of the printed circuit board. These tests can be done manually or using automatic test equipment. The important thing to note is that this equipment is a bit expensive because assembly-level testing requires the use of multiple test equipment, such as automatic X-ray inspection and automatic optical inspection equipment, to name a few.
