1.D1, D2 The first 3 pieces must be seen according to X-RAY. The infrared tube has no welding phenomenon. Every 1 hour or so in production, it is necessary to take more than one shot. X-RAY see D1, D2 welding condition, good welding. normal production;

2 Note that 1A1090A0 and 1A1090A1 are distinguished. The two PCBs are different. The BOM differs by one LK6 bit (1A1090A0 has no LK6 bit).

Solder paste requirements: Ag0.3/Cu0.7/20-38uM

Packing and transportation: White pearl cotton should be used for protection around the carton, which should be shockproof, anti-collision and anti-fall.
