All PCBs are 100% electrical tested. Electrical test mainly has flying probe test and E-fixture test. Flying probe test is used for sample or small quantities orders due to flexibility, but comparatively less efficient. E-fixture test is applied for large quantity orders or repeat orders. There are automatic picking and placing machines here. They can pick and send PCBs to E-fixture test machines automatically, and place the PCBs at appointed places after testing, according to the test result.

All PCBs are 100% visual inspected. Inspected items including shape, appearance, hole, track, solder mask, silk screen, and so on. Each batch of PCBs has microsection and thermal shock test. From microsection, it is able to check the copper thickness inside holes, copper thickness of tracks. The thermal shock test is able to know the solderability and high temperature resistance. All test and inspect results are recorded in inspection report, and shipped together with the PCBs.
