Right Handed DAQload

Wire Bonding

Wire Bonding diagram for LH hybrid (HCC and ABC) included in HybridRH_Wirebond_Detail_V6.pdf

HV and HVret are not correctly bonded from the board to the hybrid. HV pad and HVret pad on the board (the two red connections shown towards the bottom of the image below) have another pair of pads between them and the board


The initial wire bonding on the RH Daqload has the hybrid connected to these incorrect pads. The image below shows these connections, the two lower wire bonds are connected to the pads closest to the hybrid, when they should be connected to the pads beyond those (one pad right above John's finger, the other is behind his hand, not visible in the image).


This is a difference between the Left hand and right handed hybrids, the left hand is wire bonded to the closer pads for HV and HVret. The right handed wire bond goes over a pair of pads.


Same problem with minisensor from Left Handed DAQload.
