The role of wave soldering machine
Wave welding machine is a common machine and equipment in electronic device manufacturing enterprises, popular speaking, it is mainly to plug the electronic components of the plug-in into the electronic pcb board after soldering. In surface layer mounting technology (SMT), the wave welding machine of liquid filler metal is used in the double wave soldering of printed plate and the single wave soldering of surface component (SMC) circuit board. The welding of the wave welding machine specifically refers to the molten soft brazing material (lead-tin alloy), which is jetted into the solder crest specified in the design scheme by an electric pump or an electromagnetic pump, and can also be generated according to the injection of nitrogen into the solder pool, so that the printed board equipped with electronic devices in advance passes the solder crest. Flexible fiber welding that maintains mechanical and electrical connections between electronic device welding ends or pins and printed board pads. Wave crests of different geometric shapes depending on the device used
Wave soldering (wave soldering machine) is specifically used as a traditional through hole insert printed circuit board electrical assembly processing technology, and its surface assembly and through hole insert electronic devices mixed processing technology. Surface assembled electronics for the wave soldering process include rectangular frame and cylindrical chip components, SOTs, and smaller SOP devices. At this stage, the common key in China are these types: cabinet wave welding machine, double wave welding machine, small wave welding machine and lead-free wave welding machine. Its production process is: insert the component into the opposite component hole → pre-coating the flux → pre-drying (temperature 90-1000C, length 1-1.2m) → wave soldering (220-2400C) → remove the excess pin → inspection.
