Conformal Coating application is AS important, if not MORE important than selecting the right material for the application. Even the best conformal coating, if it is applied poorly will provide inadequate levels of protection.
This is due to a number of factors;
- The thickness the coating is applied,
- the level of coverage achieved and
- how well the coating sticks to the board and it’s components.
There are five methods used to apply conformal coatings:
- hand coating via Brush, Aerosol, or atomised spray gun,
- or automated Dip coating and Selective Coating Machine.
To avoid outside contaminates, in any application method, we would usually advise cleaning the PCB before coating and ensuring your workspace is clean and well ventilated.
We are happy to advise you and recommend you the best product for each step.
