METHOD OF MANUFACTURING HIGH SPEED LIGHT RECEIVING MODULE

摘要

The method is for fabricating a high speed light receiving module for a laser welding in light telecommunication. The method includes the steps of: attaching a pre-amplifier substrate(12) within a metal case(11) and simultaneously die-bonding and wire-bonding a photo diode(14) on a ceramic submount(13); wire-bonding the submount(13) to the pre-amplifier substrate(12) within the metal case(11); inserting an optical fiber ferrule housing(17) into an assembly housing(16) to be aligned with the metal case(11); firstly welding the optical fiber ferrule housing(17) with the assembly housing(16) after fine alignment; secondly welding the assembly housing(16) with the metal case(11) after fine alignment.
