Abstract:
1. A method for soldering a semiconductor optical device comprising a resin-made optical lens comprising: providing an object comprising a printed circuit board; applying a lead-free solder by plating to said object, or laminating a lead-free solder paste, a lead-free solder wire, a lead-free solder foil or a melted lead-free solder on said object; mounting leads of the semiconductor optical device on the solder area; and reflowing said lead-free solder by heating said object as whole or the solder area, wherein said lead-free solder has a melting temperature of not less than 250° C., said resin-made optical lens comprises a silicone resin-made optical lens and is integrally joined with said semiconductor optical device, and said silicone resin-made optical lens has a Shore D hardness of 20 to 90 measured by a method according to JIS K 7215.
