Wave soldering workflow

Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave. Wave soldering process: insert the component into the corresponding component hole → pre-apply flux → preheating (temperature 90-100℃, length 1-1.2m) → wave soldering (220-240℃) cooling → cut off excess plug-in pins → check .
