The function of the wave soldering machine is to solder electronic components with active pins to the electronic soldering production equipment on the circuit board. Its working principle is to flow the molten solder (lead-tin alloy) into the solder wave required by the design through the electric pump or electromagnetic pump, so that the printed board pre-installed with components passes through the solder wave to realize the components. Soldering of the mechanical and electrical connections between solder terminations or pins and printed board pads.
The wave soldering machine is a commonly used equipment in electronic production enterprises. Generally speaking, it mainly solders the electronic components of the plug-in after being inserted into the electronic circuit board. In the double wave soldering of printed boards in surface mount technology (SMT) and the single wave soldering of surface element (SMC) circuit boards, wave soldering machines with liquid solder are required. The welding of the wave soldering machine mainly refers to the molten solder (lead-tin alloy), which is sprayed by an electric pump or an electromagnetic pump into the solder wave required by the design. It can also be formed by injecting nitrogen into the solder pool, so that the pre-installed The printed board with components realizes the soft soldering of the mechanical and electrical connection between the soldering ends of the components or the pins and the pads of the printed board through the solder wave. Waves of different geometries used by the machine.
The wave soldering machine is mainly used for the traditional through-hole assembly printed circuit board electrical assembly process, as well as the mixed assembly process of surface assembly and through-hole assembly components. Surface mount components suitable for the wave soldering process include rectangular and cylindrical chip components, SOTs, and smaller SOPs. At present, there are mainly these types: desktop wave soldering machine, double wave soldering machine, small wave soldering machine and lead wave soldering machine. Its production process is: inserting components into the corresponding component holes → pre-coating flux → pre-baking (temperature 90-1000C, length 1-1.2m) → wave soldering (220-2400C) → cutting off excess plug-in feet → inspection .
