BQC believes that the SMT processing factory assembles the finished product after SMT processing and delivers the finished product. After passing the inspection, the PCBA manufacturer should sort out the inspection and test data and materials, issue a certificate of qualification, and prepare the attached test board and packaging materials for the test. Delivery shall include accepted printed boards, certificates of conformity, necessary (or specified in the contract) test data and attached test boards (for multilayer boards of Class 3 products, at least circuit continuity test data, plating Metallographic micrograph of the hole).
The attached test board can add the appropriate test pattern outside the frame of the required printed board (close to the outside of the edge) as a part of the board (panel), and process it at the same time as the required printed board, and finally complete the smt process The shape is separated to represent the finished circuit board for some destructive tests such as withstand voltage, thermal stress, simulated rework, and microsection.
