Coating defect examples
Missing coat, overflow, bubbles, particles and edge drift on PCB and PCBA.
Coating cases cover bubbles in glue, clear adhesive and chips; white glue on PCB and missing chip adhesive; conformal-coat thickness on UV film, components and automotive parts; plus splash, excess, foreign matter, bubbles, through-hole parts and thin coat.
