Abstract
A method of removing cured silicone polymer deposits from electronic components. The components are immersed in a preheated solution of a quaternary ammonium fluoride in a hydrophobic non-hydroxylic aprotic solvent with agitation. The components are then immersed in a preheated solvent consisting essentially of a hydrophobic aprotic solvent with agitation. This is followed by a rinse and spray of the components with a hydrophilic, essentially water soluble solvent, with agitation. The components are then immersed in a water bath and then rinsed with a pressurized spray of water and then dried with a N blow dry.
