It is recommended that some PCBs be repainted using conformal layers in SMT processing plants. Its primary function is to protect the non-connector port of PCBAs from dampness, dust and conduction. When some printed circuit board elements need to be protected they don't have to be painted. If the order is small, they will be repainted by hand and dried using natural wind.

If the above requirements cannot be met or if large quantities of components are required to be protected, it is necessary to create a unique conformal coating part that accepts Conformal Finish Production Tools for high quality PCBs, for spraying and UV healing.

SMT patches that call for a particular component are based on the dimensions of the PCBA, double-sided boards, elements to be avoided, and overall orders. This allows a comprehensive review of the required fixtures and their number. It is important that the design of the fixtures be reviewed by engineers who are experts before production.
