What is E-TEST?

How does PCB manufacturer ensure the bare PCB is within standard before delivery?

Once of tests it will be conducted is “E-test” which is also known as electricity test. The main purpose of E-test is to make sure there’s no open circuit and short circuit.

When it’s sample production, most of time the manufacturer will use “Flying Probe test” for E-TEST. Even though flying probe test is comparatively time consuming in terms of production efficiency but it makes sense especially the project is still on pilot phase.

Once the project enters Mass Production, usually the PCB manufacturer will produce specialized tooling for each project. No matter it’s “Flying probe test” or “tooling test”, the main target is to detect NG circuit during “E-TEST STAGE” and ensure the quality is within client’s standard.
