One of the most frequently asked question is: how to do alignment for a used shrink COF?
In some cases, we can not get a new COF for replacement. In this situation, we need used COF.

The answer is we can make a balance on left and right side when doing alignment. During bonding the heating head will make the COF expand and match a good alignment.
