This training is based on the document IPC-A-600 and in this document we find the inspection criteria for printed circuit boards, the so-called PCBs (Printed Circuit Boards). If a printed circuit board supplier has made a printed circuit board, it will be inspected before delivery to see if it meets the requirements and whether it shows no errors. That is what is broadly discussed in this document and in this training. A distinction is made in the IPC-A-600 between things that I can see from the outside on printed circuit boards that are delivered to the customer straight away. This is done with a visual inspection, possibly with a magnifying glass or microscope.
Furthermore, the connections and the printed circuit boards are also examined, e.g. a so-called microsection (sleeve) in which a part of the printed circuit board is generally a part of a test coupon, a specially made piece from the printed circuit board production, whereby internal checks are made as to whether the structure of that printed circuit board is as it should be and if there are no errors in the printed circuit board that should not be there. All this in the context of wanting to deliver a high-quality product and a product that meets the requirements and on which later the assembly can take place. Furthermore, a number of tests that can be carried out are discussed here, including tests for solderability, a purity test to see whether any contaminants are left on the printed circuit board that should not be present. This is broadly what is covered in this training.
