After the plate, PC boards, plate firmly affixed with adhesive tape, to clinch designated place with a fixed needle. 2. Try to avoid using deformation of PC board. 3. Try to use thick aluminum plate or a synthetic resin sheet 0.15 ~ 0.2mm of 0.3 ~ 0.4mm based. The pad is not hard to take, ring up and down machine, but need to pursue a uniform thickness. After the plate, PC boards, plate firmly affixed with adhesive tape, to clinch designated place with a fixed needle. 2. Try to avoid using deformation of PC board. 3. Try to use thick aluminum plate or a synthetic resin sheet 0.15 ~ 0.2mm of 0.3 ~ 0.4mm based. The pad is not hard to take, automatic machine parts up and down the ring, but the need to pursue a uniform thickness. Circuit board manufacturing capacity currently use the largest AOI inspection technology, pneumatic ring machine up and down to PCB exterior inspection line conditions up to, up and down manually ring machine, kind of technology has been developed for more than two decades in the industry. Despite the size of the circuit board line characteristic shrinkage of more than ten times, but the optical system and the mix of hardware and software systems have made great progress. Most of the circuit board products still can rely on the existing line AOI technology to check, but does have a high-end configuration of the loading plate part of the product difficult problems facing the test.
