1020 Yesterday performed electrical check of all the striplines sent from Berkeley in second batch with the following results:
Stripline # Issues
11 Broken connection between FEB Pin 44 and DPin 26. DPin 45 does not connect to any FEB Pins (it should connect to FEB Pin 42). Instead DPin 46 connects to both FEB Pins 42 (which it shouldn't) & 29 (which it should).
L1 (or 17) No GND to GND connection due to plastic shielding on warm end.
L4 (or h7) No GND to GND connection due to plastic shielding on warm end.
28 FEB Pin 1 is missing, which means DPin 33 does not connect. Broken connection between FEB Pin 12 and DPin 19.
Will keep the two working striplines and send back the two new broken striplines along with the two broken striplines received earlier from Berkeley.
1530 Finished rerouting boards for both cold and warm sides for stripline 19.
