Previous Day

Status: IVC open, tower removed. Main bath vacuum jacket is evacuated. 1K Pot needle valve closed. LN2 traps clean. Mixture is in dump, fridge evacuated.
1125 Remove S101 from purge cabinet and bag it for transport to wirebonder lab
1140 Remove S101 from bag in wirebonder lab
1150 Rebond DIB4 Side2 Pin4. Electrical check looks good, with and without lid on.
1155 Put S101 back in bag
1205 Return S101 to purge cabinet
1246 Remove S101 from purge cabinet
1315 Assemble stack, with DIB1 aligned with Tower Face 15, and the LED hole on the opposite side from DIB1. At first electrical checks showed a slight short, a few kOhm, from some pins to chassis. We removed the source holder and pushed down some wires, then replaced it, and all channels are still continuous with no obvious shorts to chassis.
DIBs 1/3/4 → Faces 5/3/1
