Summary of requirements for loading 19-1 Outer Barrel Stave:
- Load RD53a Quad modules (drawings: 150um, 400um) with connectors oriented as shown in picture above
- Load modules onto 19-1 OB L1 Stave (no drawing yet, preliminary CAD on LBL Windchill site)
- Load without collisions: 200um nominal gap / 100 micron minimum gap between modules (no assembly drawing yet showing modules on stave)
- Glue layer thickness to be 100um -50/+100um
- ESD protection during loading: grounding of tooling
- Mechanical protection of wire bonds during loading: stay clear of wire bonds, handle modules using tooling only, consider covers/shields
- Baseplate to be installed onto glue robot: weight limit 7kg (per manual)
- Stave to be removed from baseplate and transferred to test box for QC testing
