Minutes
Participants: Bill, Tina, Dave, Chris, Simon, Beni, Fernando, Eugene, Mark, Casey, Mike, and Lubomir. Tina Mann is our new FDC technician.
Production
- Dave: 80% of the staff was moved to Blue Crab. Remaining are the stringing system and the Lazy Susan table. All the stuff will be cleaned before moving inside the clean room. There were again power problems at Blue Crab. As a result all the systems for the clean room went off and were reset later.
- Next steps at Blue Crab: gluing and laminating PCBs to the wire frame, then cutting/gluing foils and building cathodes. We need the expertise of Mark and Brian. Dave will make approximate schedule for these operations so that we can ask for their help ahead of the time. Bill: not sure what is the best glue for the lamination.
Electronics
- The thickness of the rigid board of the rigid-flex assemblies was modified according to Roger's e-mail, but Bill found in the actual file that it was not. Roger was not there to clarify. Lubomir will contact Roger also regarding the foil production status.
- Bill and Dave had questions to Fernando about the solder to be used for the wires. Two solder types were used for the test wire plane: the solder recommended by Fernando and the solder paste used to tin the cathode contacts. It was easier to work with the later, while the use of the first one resulted in too thick solder layer. Fernando doesn't recommend the solder paste: corrosive and also more difficult to clean the flux. Fernando and Chris will look for a thinner solder wire.
Engineering
- Bill is working on several modifications of the stringing system:
- a protector cover for the wires needed during the soldering;
