Abstract:Package singulation process is where the whole strip was sheared to produce individual units. Existing singulation program for 1-map strip have only six (6) pattern recognition system (PRS) points along the whole strip with 240 mm length. Considering the length of the strip, it is prone with misalignment especially when the unit pitching is small. Due to a big gap of PRS points, the compensation of unit pitch has a significant variable value due to strip expansion that results to misalignment when not monitore… Show more
