Research on Process to Increasing Wave-Soldering First Pass Yield
Wave soldering refers to the process of spouting the molten soldering material into the soldering wave as per the design requirement by motor pump or electromagnetic pump,or by injecting nitrogen into the soldering pool,so that the printed board pre-loaded with components can pass through the soldering wave to realize the soldering of mechanical and electrical connection between the solder end or pin of the component and the soldering pad of the printed board.The first pass yield is a key indicator to measure the quality stability of the related processes.This paper introduces the process and method to increase the first pass yield of wave soldering through the analysis on common wave soldering defects and the formulation of relevant optimization measures.
