Puhui Electric Technology Co. Ltd

Model Number: BGA IRDA Welder T-870A-55 Brand Name: Puhui Key Specifications/Special Features: First step:According to PCB big and small, reconciliation PCB plate space between the unsolder BGA have to face top red light, let facula cover CMOS chipReconciliation light and sensor high in order to keep from CMOS chip to light about 20mmThe sensor's warm just touch CMOS chip or side so that keep warm exactlyWill be used syringes to inject liquid flux demolition welding at the bottom of the chipWelding can also help prevent loss padSecond step:

• The warm-up plate's warm up sensing head, put on the PCB's weld plate hole or sheet copper, not on the board which is below the top Al stint, because affect warm

The third step:

• Enactment warm-up warm, generally the plumbum enactment 100°C, no plumbum enactment 120°C
• Turning on warm-up on-off, 3 to 5 minutes
• Don't rise temperate too quickly, which results in components falling at the bottom

The fourth step:

• Using 936 iron and suck tin line clean weld plate after, smear a little liquid flux in order to spare wheel
