Abstract: A mechanism and method are provided for assembling a printed circuit board having a first surface, a second surface and an edge. The printed circuit board may include at least one female member to receive a corresponding male member. The mechanism may include an extension board having an edge to couple to the edge of the printed circuit board. The extension board may include a male member to extend from the edge of the extension board and to couple to the at least one male member so as to couple the extension board to the printed circuit board.

Abstract: A retainer for a circuit board and method for using the same are provided. In one embodiment, a circuit board assembly includes a circuit board, an electronic component, a plurality of electric contacts between the circuit board and the electronic component, and a retainer. The retainer has a first component secured to the circuit board and a second component secured to the electronic component. The retainer allows for movement of the electronic component in a first direction towards the circuit board while simultaneously preventing movement of the circuit board and the electronic component in a second direction away from one another when the electric contacts melt.

Abstract: A method of wave soldering a circuit board while avoiding reflow of a solder joint on the topside of the board from heat conducted from the solder wave through at least one via in the board in heat conducting relation with the topside solder joint, comprises subjecting the circuit board to a solder wave and absorbing heat being conducted from the solder wave through the at least one via with an endothermic material in the via hole which undergoes a heat absorbing reaction. The heat absorbing reaction of the endothermic material is preferably a phase change, such as melting. The melted endothermic material is retained in the via hole during wave soldering by capillary forces and a cap on the lower end of the via hole. A disclosed method of making the circuit board includes locating the endothermic material in the via hole by inserting a preform of the endothermic material into the via hole or hot dispensing the endothermic material into the via hole.
