PURPOSE:To improve the electrical insulating properties by allowing the surface of gold to absorb the molecules of a trialkyl thiophosphite, a trialkyl thioantimonite, etc., dissolved in an organic solvent. CONSTITUTION:A base plate metallized with gold is immersed in a solution of a trialkyl thiophosphite, a trialkyl thio-antimonite or a trialkyl thioarsenite in an organic solvent so that the molecules of the ester are absorbed on the surface of the gold, which is then washed with an organic solvent and dried if necessary.
