| Action Item | Who | When | Status | |
| 1 | Requalify a new machine shop for MCM machining. | David Rich | 2/18/04 | 25 boards were taken to a machine shop in Alameda 2/12/04. |
| 2 | Notify Teledyne when boards machined by the new vendor are shipped to Teledyne, so that they can watch out for differences that might affect them. | David Rich | ||
| 3 | Pitch-adapter flex circuit needs formal PCB approval. | Nick Virmani | 2/18/04 | |
| 4 | Add solder wire and SN62 solder paste to the approved materials list. | Nick Virmani | 2/18/04 | |
| 5 | Purge down-rev connectors and GTRC V6 chips from Teledyne following completion of the preproduction. | Ralph Martin | ||
| 6 | Reduce torque specification for jack screws of the connector savers. Revise LAT assembly drawings accordingly. | David Rich | 2/18/04 | |
| 7 | Reduce torque specification for jack screws of the connector savers. Revise Teledyne process instructions accordingly. | Brian Caplen | 2/18/04 | |

Done 2/20/04 |
| 9 | Perform source inspection on parts at SLAC before delivery to Teledyne. No more drop shipping. | Jeff Tice | ||
| 10 | Qualify automatic die attach before introducing it into the flight production. | Brian Caplen | ||
| 11 | Make longer, wider carriers to improve handling of MCMs with wire bonds. Flight production can begin with the present tooling. | Brian Caplen | ||
