Background

SMT is a surface assembly technique, and is the most popular technique and process in the electronic assembly industry at present. The surface-mounted component without pins or short leads is mounted on the surface of a printed circuit board or other substrates and is soldered and assembled by methods such as reflow soldering or wave soldering. Wave soldering is a process technology which forms solder waves with specific shapes on the surface of molten liquid solder by means of the action of pumping pressure, and forms solder points in a pin soldering area when an assembly component inserted with components passes through the solder waves at a certain angle. The components are preheated in a preheating zone of the welding machine during the transport by the chain conveyor (the preheating of the components and the temperature to be achieved are still controlled by a predetermined temperature profile). In actual welding, the preheating temperature of the component surface is also controlled, so that corresponding temperature detection devices (such as infrared detectors) are added to many devices. After preheating, the assembly enters a tin bath for welding. Molten liquid solder is contained in the tin bath, and the wave of fixed shape is ordered out to the molten solder to steel bath bottom nozzle, like this, just is heated by the solder wave when the subassembly welding face passes through the wave, and the solder wave just also wets the soldering zone and carries out the extension filling simultaneously, realizes welding process finally.
