Abstract
Disclosed is a method of removing silicone rubber encapsulating material from micro-electronic circuits. The encapsulant is broken down molecularly and removed by a solution of tetramethyl-ammonium hydroxide which is diluted with an alcohol such as 2-propanol. It was found that this stripping solution causes minimal swelling of the encapsulant and leaves no significant residue which cannot be removed by standard rinsing.
