D. Repeated several adjustments;
E. During adjustment process, the heated of galvanic probe is strictly
prohibited from contacting with any objects, so as not to affect the
accuracy of measuring temperature;
F. After temperature adjustment, you should fix the probe, to avoid the
probe vibration measurement of the temperature of the equipment
G. The method of the adjustment applies only to the two parallel curves in
a smooth uniform deviation, and it is invalid to the temperature which is
from top to bottom jitters free-laws regulating!
H. The upper part of the internal galvanic Duct location: Remove the upper
heater nozzle, at a distance of 2-3cm at the edge wind-cone.
8. There is no booster thermocouple temperature curve on the bottom of
the computer screen, so you have to adjust the process of the lower
part of the heaters by visual.
9. Fixed the galvanic line with foil stickers on the bottom of PCB board (as
opposed to the upper heater set back on the PCB board), so that the
probe of the booster thermocouple is located just 2mm above the
mouth of the bottom hot-air nozzle, and adjust the mechanical parts,
make the upper hot-air nozzle deviate from the heated parts to avoid
cold air affect the temperature of the heated parts.
10. The caution is same as the top heater.
11. The methods of adjustment:
A If the outer temperature is lower than the bottom, you should adjust the
lower internal galvanic probe downward.
B If the outer temperature is higher than the bottom; you should adjust the
lower internal galvanic probe upward.
8. Reballing process
1. Fix the BGA chip on the base of universal reballing station ; adjust the
four slipper blocks to fix the chip to make it on the center of the
reballing kit.
