• PIXEL_CARRIER_A (ppt)

This version is the first prototype of the PIXEL_CARRIER (6 layers Cu). The ladders are glued on the bus.

Pixel_carrier glued on interface card with protection and fans (the chips are glued on the bus)

   The pixel carrier is glued on an interface card. 10 pixel chips are glued and bonded on this carrier.
