VAL K3-165 Module
Setup
- KaptonIII Forward Hybrid (K3-165) populated with 12 ABCD3T.
- SEQUENCER - DRAFT readout.
- Fwdlvds Support Card.
No optical readout is used, we use the electrical lines.
Parameters
- Vdd = 4.00 V (on hybrid).
- Vcc = 3.50 V (on hybrid).
- Edge detection circuitry disabled.
- Compression mode Level (X1X).
- Bias Current = 220uA.
- Shaper Current = 31.2uA.
- Strobe Delay Setting:
| Input Charge(fC) | 0.25 | 0.50 | 0.75 | 1.00 | 2.00 | 3.00 | 4.00
|
| Setting* | 20. | 26. | 34. | 36. | 38. | 38. | 38.
|
* Setting in 0 - 50 range.
Trimming
No trimming was done because lack of time. We used the same trimming we got
for the hybrid.
Noisy Channels
After module construction a lot of noisy channels appeared. A cross-check
showed that the channels were shorted at the fanins (picture). The bond footprint was too big due to a
misbehavior of the bonding machine.
Stability
The module is stable.
