Abstract
An apparatus to retain an assembled component on one side of a double-sided printed circuit board during reflow of other components subsequently positioned on an opposite side of the double-sided printed circuit board and methods for manufacturing and using the same. The retainer includes a heat-expandable member and a retainer member. Being formed from a heat-expandable material, the heat-expandable member is coupled with the retainer member and is disposed about a periphery thereof. The retainer member is configured to be coupled with a component and, when the component is assembled onto a double-sided printed circuit board, to be received by an opening formed in the double-sided printed circuit board. The heat-expandable member is configured to expand during assembly of the component, engaging an inner surface that defines the opening. Thereby, the component is retained and supported when the double-sided printed circuit board is subsequently inverted, populated, and reflowed.
