Abstract:
A method of manufacturing an optical module having a housing of synthetic resin incorporating a lens therein and a semiconductor device of a metal-cap package structure which is held in optical axis alignment with the lens, comprising the steps of:applying a first thermosetting resin as a plurality of spaced dots to surfaces, to be joined, of a stem of the semiconductor device and an end of the housing;holding the lens and the semiconductor device in optical axis alignment with each other;supplying a high-frequency current to a coil extending around said stem to heat the stem to thermoset said first thermosetting resin by high-frequency induction heating;depositing a second thermosetting resin in a circumferential pattern on an outer circumferential surface of said stem along the end of said housing; andthermosetting said second thermosetting resin by heating.
