The display window which
shows in digital form the
temperatures of the air, T.C.
and preheater at the time
measurement point
The graphics display window illustrates the temperature, time settings and actual values for the profile. The vertical bars represent
temperature and the horizontal bars represent the process time. The bars can be moved vertically or horizontally to change the
temperature or time settings of the profile by simply clicking on the vertical or horizontal bars and dragging them.
The horizontal dotted lines (Red & Blue) in the graphics display window are reference temperature markers and may be moved
anywhere in the profile.
The BGA unit has three temperature probes. One is located inside the micro oven and one is located inside the preheater. The third
one is known as thermocouple (T.C.) and is connected to the front panel of the BGA module. Each curve illustrates the temperature
of a given probe at a specific time. The T.C. probe is typically placed in between the chip and the PCB by the first balls when trying to
establish a removal process for BGA for the first time. It can be placed in any other desired location. The vertical, dotted lines are
designed to help read the temperature curves easily. The temperature and time measurement window is displayed at the bottom left
hand corner of the graphics display window. Curves and time measurement bars can be added, (maximum of 6), or removed and the ir
attributes changed. Please refer to MENU section.
