- Bill: probably there will be a delay with the clean room construction, because some of the specifications (like +/-2% humidity control) were not realistic, which delays the bidding process. Eugene: the leading time is about 3 months, so expect it ready by December, although they will try to speed up the construction.

We discussed what type of microscope we need for the wire and flex soldering. Casey who is expected to be the main user wanted to have bigger working distance than the new Fernando's microscope. It will be nice also to have a fast camera to work in real time just looking at the screen.

- Fernando: received the first article PCBs but has not looked yet; still waiting for F117 to be ready for use. Mark is helping in making space there. Fernando will test the boards by himself, including mechanical tests. If they pass, CEM will continue with the full production, then all the boards together will be send for stuffing.

- two vendors responded for the 18m cable assembly. If they both meet the requirements, the lower price criteria will apply. Bill was concerned about the length of the part of the cable on which the ground is removed. Fernando: that length is equal to the distance from the front of the magnet to the FDC package, there's no big change in the diameter of the cable, so it shouldn't be a problem to feed the cables between CDC and BCAL if taking the FDC upstreams for maintenance. No news about fADC.
