Analysis of some phenomenon in PCB fabrication:
Issue: virtual welding, continuous welding, leakage welding
Result analysis:
(1) The amount of flux coating is too small or uneven;
(2) Some of the pads or solder fillets are heavily oxidized;
(3) The PCB design is unreasonable;
(4) The clogged foaming tube and the uneven foaming cause the uneven flux coating .
(5) The operation method is improper when hand immerse tin;
(6) The inclination of the chain is unreasonable;
