Abstract

Disclosed is a two-part pin system used during a stacking operation when fabricating Thermal Ink Jet (TU) arrays. By using die to substrate equipment pin 12 and 14 shown in the accompanying figure insert from the bottom of substrate 2 prior to placement of die 4. This establishes datum 20 during the primary die bonding process. Thereafter, substrate 2 reroutes to the die to substrate equipment where substrate 2 is staged on the previously installed pins 12 and 14. Pin 16 and 18 now insert from the top of substrate 2 to establish datum 22.
