Abstract

Serial Reading Quasi Test Method by Single HGA Picking Up Positioning Serial Reading Quasi Test Method by Single HGA Picking Up Positioning 1. Method of Single HGA Picking Up Positioning HGAs to be tested are carried just under the pick up unit. HGAs are raised by the pick up unit to separate from the HGA tray. In this state, the serial number reading and the quasi test are performed.··(Fig.1) By separating from the HGA tray and performing the two measurements to the datum on space, mechanial tolerances that might be generated from the tray can be eliminated.
