5. Gluing Dots of glue Tape in areas with wire-bonding 8 hours curing
UHU Endfest
Tape in areas with wire-bonding
PPI Tape
8 hours curing

6. Wire-bonding
Remove frame
Wire-bond jigs

7. Wire-bonding
Pitch 80mm

8. Potting, transport and bending
Proposal to do potting with Dymax 9001.v3.1 and bending of flex at CERN
100 transport frames in production in Bonn
With space for connecting the readout board for testing

9. Next Test with heater and flex and flex dummies
Assembled one real to validate tooling
Check with company for production of 4(?) sets of tooling to distribute
Distribute: tooling and dummy components

11. Procedure The steps for the heater assembly are:
Clean jigs with isopropanol, prepare glue UHU Endfest profishop.de/downloads/dl/file/id/190/technisches_merkblatt_uhu_plus_endfest_300.pdf, prepare tape Tape PPI 577RF (
Weight parts
Position flex on jig (wire-bond pads touch surface of jig), vacuum on.
Place tape on flex. Position bare heater on jig, vacuum on.
Pick-up heater with pick-up tool. Can be place in mount.
Put glue dots on flex.
Remove 2nd foil from tape (min. 5 min waiting after placement) .
Place heater on flex.
Put weight on pick-up tool during curing.
Curing (~8h), vacuum off for heater, for flex vacuum still on until curing done.
Cutting of flex frame if needed for wire-bonding, alternatively keep frame.
Wire-bonding.
Transport.
Potting
Bending after cell assembly.
