3 Methods to Prevent Circuit Board Cobwebbing
Coating
23/1/2025
Just as a quick summary, cobwebbing is one of the most common processing issues that PCB manufacturers face when conformal coating. It is caused in general by premature drying of the coating as it is atomized and sprayed. It can be solved using a number of approaches designed to slow down the drying process. While challenging, methods to eliminate cobwebbing are fairly straightforward and have been tested and proven to last.
