Some PCBs in SMT manufacturing handling plants have to be repainted with conformal covering. Its main function is to avoid wetness, dirt, and transmission to shield the non-connector ports of PCBAs. If some elements in the circuit card require to be shielded, they do not require to be repainted, and when the order amount is small, they are normally repainted manually and dried out by natural wind.

In SMT handling, if the above demands are not met or some components require to be shielded in large quantities, it is essential to customize a special conformal covering component, which cooperates with Conformal Coating production devices of High-Quality PCB for totally automatic splashing, UV treating, and so on.

The part of the SMT spot that calls for a component will certainly involve the size of the double-sided board, PCBA board, the variety of components to be prevented, and the overall number of orders to review the number and design of the called for components thoroughly. For that reason, it requires to be reviewed by expert designers prior to manufacturing.
