Inverter pcb product process description:
Production process: lead-free process
Process of production process: smt, dip, burning, testing, packaging
Solder paste requirements: Ag3.0/Cu0.5/20-38uM
IC48 face first, pay attention to check the X30 number patch memory slot, if there is a virtual soldering phenomenon, please add adhesive tape on the steel net to increase the amount of solder to prevent the memory slot from soldering. The first 3 pieces were inspected by X-ray for BGA, and the IC had no solder joints. The 50-chip test was performed with x-ray sampling inspection, and the IC had no solder joints. Some materials are not the same. When you are producing, you must separate and separate the whole process. Do not confuse.
Reflow soldering temperature setting: welding maximum temperature is 250-253 °C, super 230 °C welding time control 40-60S.
