The product feature of hot air touch screen BGA soldering station
Machine’s emergency button, any urgent condition, it can be pressed, then BGA rework machine immediately stop working, and cross-flow fan start to cool for PCB/chip and infrared preheating area.
Tempe sensor can monitor the real-time temperature on chip, USB 2.0 for software uploading or downloading the screenshot etc.
Air switch, which will stop when currency is not normal(more or less), such as, leakage of electricity, short circuit, the power voltage exceeds the normal scope(+/- 10%).
“GND” for connecting the ground wire to provide safer technology using machine.

Tidy and simple operation interface, one temp sensor port, USB 2.0 port, switch of light and an emergency button. The industrial computer with a touch screen(7 inches), it can keep at least 5000 groups of profiles, so that, every successful profile can be kept for your reference next time.

The product qualification of hot air touch screen BGA soldering station
The picture as above is a Simulated automobile transportation machine, all of our machines will be running for constant 3 days, then will be vibrated for at least constant 24 hours, after than, let it be working for durative 24 hours, too, in order to find any possible problem out, and prevent possible problem from happening at customers. So far, we are the only one who dose like this in this industry in China.

Delivery, shipping and service of the hot air touch screen BGA soldering station
All of machines packed in plywood box (no need fumigated), stuffed by foam, wood bars to fix, to make sure machine will not be shaken during transportation.
The heaters are the only consumable on these machine, but we provide 3 years warranty, 1 year for whole machine, if distributor, offering 2 years for whole machine.

The FAQ of hot air touch screen BGA soldering station
1. Q: What is a PCB ?
A: Printed Circuit Boards,simply put, which made from layers of fibreglass and copper, glued together.
2. Q: Can I use 110V for this machine?
A: Yes, it can, but please tell us in advance, as some components will be changed.

3. Q: Can I use the desoldered chip to solder on PCB again?
A: As the base point are still existing, after reballed, it can be used again.

4. Q: How can I know which chip has a problem?
A: Usually, you need a X-RAY machine to diagnose.

A few tips of repairing :
Conductor Repair, Welding Method
Prior to using any welding equipment, certain precautions should be taken. The equipment should have electrodes cleaned, aligned and set for the proper board thickness.

Test samples that have similar circuit widths, spacing, thickness, surface finish, contour, etc. Observe and test the weld quality, alignment, discoloration, fusion and the appearance of the base material in the area of the weld. Readjust the weld equipment settings and repeat until acceptable results have been achieved.

The alignment of the welded ribbon to the circuit pattern should be within 0.050 mm (.002"). The weld bond strength should exceed the circuit/base material bond strength.
PROCEDURE
1.Clean the area.
2.Select a section of Kovar ribbon of the same width as the conductor pattern being repaired ± .050 mm (0.002").
3.Cut the ribbon approximately 3.0 mm (.120") longer than the section being repaired.
4.Clean the ribbon conductor and base material surrounding the repair area.
5.Place and center the ribbon over the section to be repaired leaving equal ribbon end lengths on each side and parallel to the circuit pattern.
6.Place the PC board under the weld electrodes so that the electrodes are depressed to the area of the weld.
7.Hold the ribbon in place with the Precision Tweezers until the weld is completed. Weld in place using settings based on the accepted test samples.
8.Clean the area.
9.Carefully inspect the joint for weld quality and alignment.
10.If required, apply a small amount of flux and tin the entire area with solder.
11.Clean the area.
Coat the repaired area with epoxy if needed.China Touch Screen Bga Soldering Station manufacturers
