Is lubricant like WD-40 a good contact cleaner?
Generally, contact cleaners contain 100% solvent, which dissolves grease, carbon deposits, and other contamination, and allows it to run off. The solvent then evaporates, leaving a clean, conductive surface behind. Aerosol lubricants, like WD-40,...

How Thick Should I Apply Conformal Coating?
Conformal coatings are generally very thinly applied, which provides the best protection possible, but minimizes heat entrapment, excess weight, and other issues. Typically, conformal coating is applied between 1 to 5 mils (25 to 127 microns)....
