. The wire is wound, snapped, and dropped on its contact before the welding process, so we can usually see soldering The solder joint is generally a reflow solder joint surrounded by tin-lead solder. 2

. 5. The soldering surface does not move during the reflow soldering process. If the welding end moves during the soldering process, it depends on the movement and time, which will not only affect the shape of the solder joint, but also cause false soldering and inner hole conditions

. The bottom component of the large board is easily dropped during the second reflow process, or the bottom solder joint is partially melted, causing solder joint reliability problems

The reflow soldering oven equipment is the key equipment in the SMT assembly process. The solder joint quality of PCBA soldering depends entirely on the performance of the reflow soldering oven equipment and the setting of the temperature curve

. When the board goes through the oven, the solder melts and the component body slightly falls on the solder and pushes it toward the component lead to form a greater Heel Joint
