Optical Module Component Features that Aid Adhesive Attachment

Abstract:

A cap for an optical module includes features that aid in adhesive attachment. In some examples, the cap includes a standoff configured to initiate capillary action upon contacting adhesive on a substrate to move the cap toward the substrate and an alignment feature configured to control lateral movement of the cap with respect to the substrate as the capillary action moves the cap toward the substrate. In other examples, the cap includes a standoff configured to initiate movement of an adhesive away from a substrate via surface tension and wetting upon contacting the adhesive and an alignment feature is configured to control lateral movement of the cap with respect to the substrate as the adhesive moves away from the substrate.
