Abstract
An optoelectronic module includes a spacer with an optical component mounting surface, a fluid permeable channel, and a module mounting surface. The fluid permeable channel and module mounting surface allow the channels to be sealed to foreign matter during certain manufacturing steps and to remain free from blockages, such as solidified flux, during certain manufacturing steps. Further, the channels can permit heat to escape from the optoelectronic module during operation.
Claims9
A method of manufacturing an optoelectronic module from a plurality of optoelectronic modules, the method comprising the steps of:
- electrically mounting a plurality of active optoelectronic components to an active optoelectronic component substrate, the active optoelectronic component substrate being laterally surrounded by a spacer forming a chamber, the spacer including
- an optical component mounting surface,
- a fluid permeable channel formed within the spacer which comprises a fluid-permeable membrane and is operable to permit the outflow of fluids from the chamber, and
- module mounting surface, and wherein an adhesive channel partially surrounds the chamber from a top view facing the optical component mounting surface, wherein the fluid-permeable channel extends into the module mounting surface;
- applying an adhesive to the optical component mounting surface comprising filling the adhesive channel with the adhesive;
- mounting an optical component to the optical component mounting surface;
- curing the adhesive;
- mounting the optoelectronic module via the module mounting surface to an adhesive substrate;
- and
- separating the plurality of optoelectronic modules into singulated optoelectronic modules.
