To protect a printed circuit board (PCB) from the elements, including moisture, dust and extreme temperatures, conformal coatings are often applied.
If the assembly is to have a conformal coating, then all residues (including flux residues) must be removed before application, so the PCBA will have to go through a cleaning process. Residues can inhibit proper adhesion of conformal coatings. Especially no clean residues. Since they are formulated not to be cleaned, the residues from no clean products can be left on the board in unwanted areas with detrimental effects on the PCB. They’re not necessarily designed to come off. That creates a cleaning challenge if you need to clean off a residue that was not designed to be removed.Our customer based, technical approach to all cleaning and conformal coating projects ensures you get the right solution!
