PROCESS AND APPARATUS FOR SOLDERING A PREFLUXED ELEMENT, SUCH AS, WAVE SOLDERING SURFACE MOUNTED DEVICES TO A PREFLUXED PRINTED WIRING BOARD

摘要

Wave soldering process and apparatus for the soldering of elements such as, for example, printed circuit assemblies with surface mounted components and the like which yield improved soldering results by promoting the penetration of solder into narrow spaces between components, the filling of small holes in a board, filling crevices, filling corners adjacent to solder masks and all other areas where solder wetting is difficult to achieve with conventional machines. The process provides the steps of moving an element in a predetermined path, forming a solder wave beneath the path so that at least a portion of the element passes through the solder wave, and producing an oscillation in the solder wave during the passage of the element therethrough.
