Features :
1. Choose imported high-precision materials (temperature sensor, PLC, heater) to control
BGA desoldering & soldering procedures precisely.
2. Top & bottom temperature areas heat independently, And it can set up 8 rising
temperature segments and 8 constant temperature segments to control. It can save 10
groups of temperature curves at the same time.
3. Choose imported high-precision thermocouple to detect the top/bottom temperature
precisely.
4. Top & bottom heating can be controlled independently by the temperature graphs. A
cross-flow fan cools rapidly to protect the PCB from deformation when welding.
5. This machine can be connected to a computer to be controlled more conveniently with
a built-in PC serial port and a proprietary software attached to it.
6. After finishing desoldering & soldering, there is an alarming. The machine is equipped
with a vacuum suction pen to facilitate the removing of BGA after desoldering.
7. For large thermal capacity of PCB or other high-temperature and lead-free welding
requirements, all can be handled easily.
E. Operation Steps
1. Preheating
Preheat the BGA and PCB before repairing. The temperature in thermostat is usually
set at 80
℃
-100
℃
,time 12-24 hours, to remove the moisture in PCB and BGA, and
prevent burst when heating.
