Abstract:
1. A method for manufacturing electronic and/or optical components, comprising applying, on a surface of a substrate, a water removable hot melt composition comprising an alkane based wax and an amorphous material as a masking material, the hot melt composition having a melting point of between 40° C. and 85° C. and a viscosity of between 5 and 20 mPa·s at not less than one temperature within the range of between 50° C. and 140° C.; and removing the hot melt composition from the substrate with the aid of a water-based stripping fluid having a temperature of at least 10° C. above the melting temperature of the hot melt composition and below the boiling point of the water-based stripping fluid, wherein said water-based stripping fluid consists essentially of water.
