die is mounted on top of the substrate, and is Encapsulation Substrate enclosed
in a plastic mould (Figure 2.95). Ball pitches are decreasing from 1.27 mm to 1.0
mm and as low as 0.5 mm for new chip scale Balls packaging. For high reliability
Water Rinse: After each process step, the substrate is rinsed to ensure that none
of the chemicals is transferred to the next bath. Each step relies upon the
chemical reaction within itself and can contaminate the reaction of another bath.
The calibration for the drift compensation takes about one minute and can be
done while a work process is executed. Any variation in the substrate itself, such
as inaccuracies in the positioning caused by deviation of the fiducials, is detected
