Wire Bonds and Connections

Full wire bond diagrams for the hybrid (HCC and ABC chip) are included in HybridLH_Wirebond_Detail_V6.pdf

All of the connections on the LH board seem to work fine, the HV filter (region on the board where C1,C2,R4-R8 are located has all the correct components).

Mini-Sensor

Mini sensor is wire bonded to ABC chip and glued to the HV pad beneath it. Mini-sensor was not correctly cut and is larger than it is supposed to be (shown below)

Sensor should have a bond connecting it to the HVret pad (the outer metal pad). Instead the HV and HVret are shorted together, causing us to measure much larger than expected currents.
