  SMT reflow welding introduction

  Reflow refers to the soldering of mechanical and electrical connections between the solder ends or pins of surface-assembled components and the printed board solder pad by remelting the paste solder preallocated to the printed board pad. It provides a heating environment to melt the solder paste so that the surface mount components and PCB solder pad can be reliably combined together through the solder paste alloy. According to the technical characteristics of reflow welding, it is divided into gas phase reflow, infrared reflow and hot air reflow. The current mainstream equipment adopts hot...

  Comparison of advantages and disadvantages of nitrogen reflow welding

  Many large SMT processing enterprises or large electronic product manufacturers not only use reflow welding machines but also use nitrogen reflow welding. So what are the advantages and disadvantages of nitrogen reflow welding compared with ordinary reflow welding? Guangsheng De here to share. Nitrogen reflow welding Advantages of nitrogen reflow welding: Reduce circuit board oxidation by reflow furnace. Improve reflow welding capability. Enhanced reflow soldering properties. Reduce the hole rate of the circuit board reflow, because the oxidation of the...
