PCBA coating should be transparent and cover PCB and components evenly. Whether the coating is uniform or not is related to the coating method to a certain extent, which will affect the appearance of printed circuit board surface and the coating condition of corners. In SMT SMT chip processing, there will be a "deposition line" of coating accumulation or a small amount of bubbles at the edge of the board, which will not affect the function and reliability of the coating.
