Wednesday Stand-Up

Check-in vs. the week's plan

Where we are mid-week

Quick check against the four priorities we set Monday. Two big positives: order tracking now lives in one source of truth (the Procurement Tracker sheet), and #vendor-ops is catching vendor holds within minutes. Let's go priority by priority, then the open questions.

This week's priorities

  1. Finalize the fab request (was due Tue). Mostly out
  2. Prepare 1 MQC-01 for external testing. In progress
  3. Design & fab the 10 MHz adapter board — Curtis. Needs a check
  4. Finalize MQC-02 packaging plan / vacuum-packaging validation. At risk

Where each priority stands

Mid-week read
4 priorities
  • 1 · Fab request — mostly out. MQC-02 cards placed across TTM + backups (IEC, Sierra): compute/power PO booked at TTM, physics via-fix approved (rev A03), analog array re-approved, VC-blade invoice hold cleared (Lenore paid 7/27). Open: TTM PO 1011 (VC blade MQ2602-11103) sitting on a technical-query hold.
  • 2 · MQC-01 for test — real momentum. Heater temperature is now controlled from the STM32 (off manual) as of last night — a big step toward automated operation. Next: wire GUI packets to tune the PIDs. Gate: heater glitching / control-loop coupling; needs stability work + likely some on-site help.
  • 3 · 10 MHz adapter board — no movement. Nothing new this week; Curtis is fully loaded (VC-blade fab + assembly + clock). Connector was picked 7/17 (SAMTEC FTSH-107). Confirm an owner + start date today.
  • 4 · MQC-02 packaging — still exploratory. Bay Photonics (vacuum reflow vs. seam-seal — open), Master Bond epoxy ships Aug 11, Atomica cell on hold to Jul 31, FieldLine vapor cells slipped to ~Sept. Need a packaging-approach decision.
On track for the week?

Open questions & asks

What still needs an answer

Vendor + lab
who owns each
Did we answer Safra's flagged vendor questions? Partly. The photodetector / vapor-cell blade part-number mix-up is resolved — Wale corrected the labels with IEC (photodetector = MQ2602-10302, VC blade = MQ2602-11103). Still open: TTM's technical-query round on the VC blade (Issue #13 + array-data approval; they also need the PO#/tape number to locate the part) — waiting on us since Safra's out. Confirm the answers went back to Tushar / TTM.
  • Clock stability — decide how much PID-tuning effort we put in and whether we pull in on-site help; control-loop coupling is the real risk.
  • Shared-hardware coordination — we had collisions on the same MQC-01 unit this week. One owner per unit + coordinate lab changes with Gaby & Newton.
  • Robbie's parting analysis — MQC-02 likely must run away from the magic temperature; map stability vs. VCSEL temp to pick the operating point.
