BGA Chip Reballing And Rework

                                                             Automatic BGA Chip Reballing And Rework

Automatic BGA Chip Reballing and Rework is a process that uses a machine to remove and replace faulty or damaged

 ball grid array (BGA) chips on printed circuit boards (PCBs). The machine is equipped with a heating element, a soldering

 tool, and a vacuum system that are used in conjunction to remove and replace the chips.

1.Application Of laser positioning BGA Chip Reballing And Rework

Work with all kinds of motherboards or PCBA.

Solder, reball, desoldering different kind of chips: BGA,PGA,POP,BQFP,QFN,SOT223,PLCC,TQFP,TDFN,TSOP, 

PBGA,CPGA,LED chip.

DH-G620 is totally same as DH-A2, automatically desoldering, pick-up, puting back and soldering for a chip, with optical alignment for mounting,no matter whether you have experience or not, you can master it in one hour.

What is the temperature resistance of a PCB circuit board? How do you test the heat resistance of a PCB circuit board?

These are common questions from customers. The following information will provide a detailed answer.

First: What is the maximum temperature resistance of a PCB circuit board, and what is the duration of that temperature resistance?

The maximum temperature resistance of a PCB board is 300 degrees Celsius for 5-10 seconds. For lead-free wave soldering, the temperature is about 260 degrees Celsius, while for lead solder, it is 240 degrees Celsius.

Second: Heat Resistance Test

Preparation: Circuit board production board

1.Sample five 10x10 cm substrates (or plywood, finished boards); ensure they have copper substrates without blistering or delamination:

• Substrate: 10 cycles or more
• Plywood: Low CTE, 150, 10 cycles or more
• HTg material: 10 cycles or more
• Normal material: 5 cycles or more
• Finished board:

    Low CTE, 150: 5 cycles or more

    HTg material: 5 cycles or more

    Normal material: 3 cycles or more

2.Set the temperature of the tin furnace to 288 ± 5 degrees Celsius and use contact temperature measurement for calibration.

3.First, use a soft brush to apply flux to the surface of the board. Then, use tongs to place the test board into the tin furnace. After 10 seconds, remove it and cool it to room temperature. Visually check for any bubble bursts; this counts as one cycle.

4.If foaming or bursting is observed during the visual inspection, stop the immersion tin analysis and immediately begin the explosion point failure mode (F/M) analysis. If no issues are detected, continue the cycles until the bursting occurs, with 20 cycles as the endpoint.

5.Any bubbles need to be sliced for analysis to identify the source of initiation points, and photographs should be taken.
