Parameter
：
1. Embedded industrial PC, high definition touch screen, make the operation humanity,
CPU control, and instant curve analysis function. Real-time display settings and actual
temperature curve, which can also be used to analyze and correct the curve if
necessary.
2. It uses high precise k-type thermocouple closed-loop control and automatic
temperature compensation system, with CPU and temperature module to enable
precise temperature deviation to add and subtract 2 degrees. Meanwhile, external
temperature measurement connector enables temperature diction and accurate
analysis of real time temperature curve.
3. V-groove PCB works for rapid, convenient and accurate positioning, which can meet all
kinds of PCB board of positioning.
4. Flexible and convenient removable fixture on the PCB board can protect the PCB fringe
devices from damaging and transmuting. It can also adapt to various BGA ‘s reworking.
5. Various sizes of BGA alloy nozzles, which can be adjusted 360 degree for easily
installation and replacement.
6. Three temperature areas can independently heat and they are multiple temperature
control, which can ensure best integration of different temperature areas. Heating
temperature, time, slope, cooling and vacuum can all be set in the human-machine
interface.
7. There are 8 stage temperature controls up and down. Massive storage of temperature
curves which are accessible at any time according to different BGA. Curve analysis,
setting and adjustment are also accessible via touch screen. Three heating areas adopt
independent PID calculation to control heating process to enable more accurate
temperature.
8. It uses high power cross-flow fan to enable fast cooling of PCB board and prevent PCB
from deformation. There are also internal vacuum pump and external vacuum chuck,
