Abstract: An electronics housing includes a first enclosure portion defining an internal cavity, a second enclosure portion sealing the internal cavity, at least one vent positioned in one of the first enclosure portion and the second enclosure portion, the vent comprising a through hole protruding from an exterior edge of the vent to an interior edge of the vent, a malleable sealing member disposed in the vent, and a rigid retaining member disposed in the vent.

Abstract: A fastener is provided for fastening a printed circuit and an electronics housing. The fastener has a lead-in feature extending from the fastener and at least one pin extending the fastener. An intermediate standoff portion may be disposed between the lead-in feature and the pin. An electronics housing may be provided that includes the fastener, an electronics housing structure, and a printed circuit board (PCB) disposed adjacent to the electronics housing structure. The lead-in feature may be press fit into an aperture in the housing structure aperture, and the pin may be press fit into an aperture in the PCB. A method of forming an engine control unit is also provided. The method includes providing a PCB, press fitting a fastener to the PCB, dispensing thermal interface material onto a housing structure, pressing the PCB onto the thermal interface material, and press fitting the fastener into the housing structure.

Abstract: An electronics module includes a module housing having a base structure and a plurality of side walls. A module cover contacts the side walls and is connected to the module housing via at least one fastener. The module housing includes at least one fastener boss for receiving the at least one fastener. Each of the fastener bosses includes a fastener hole protruding partially into the fastener boss and a vent hole connecting the fastener hole to an opening on a surface of the fastener boss exterior to the module housing, and a sealant disposed in the fastener boss, thereby preventing external air from entering the electronics module through a fastener connection.
