Circuit board, Circuit board, PCB board, PCB welding technology in recent years, the development of electronic industry technology, you can notice a very obvious trend is reflow welding technology. In principle, traditional inserts can also be used reflow welding process, which is commonly referred to as through-hole reflow welding. The advantage is that it is possible to complete all the solder joints at the same time, so that the production cost is minimized. Temperature-sensitive components, however, limit the use of reflow welding, whether it is an insert or an SMD. Then people turn their eyes to the choice of welding. In most applications, selective welding can be used after reflow welding.
This will become an economical and efficient way to complete the welding of the remaining inserts and is fully compatible with future lead-free soldering.
