– Incoming inspection, cleaning, prep for processing: 10 – Tooth strip cutting, handling, organizing for production: 10 – Attachment of tooth strips, removal of excess epoxy: 20 <-- Jig required? – Dimensional check, excess epoxy removal, spot cleaning: 10 – Mask solder pads, bag, place in inventory, final inspection, package for storage or shipping: 10
– Incoming inspection, cleaning, prep for processing: 10 – Pin insertion (qty = 4): placement, press, align, glue, bake: 30 <-- Jig required? – Mask solder pads, bag, place in inventory, final inspection, package for storage or shipping: 10

dimensional accuracy before being routed through various epoxy and cleaning processes as they are prepped for assembly. Inspection results are documented, and if anomalies are found, an electronic non-conformance report is written.
– Acceptance tests of these boards include leakage current measurements (<0.5 nA) and
continuity tests on each channel. The tests are performed at room temperature.
– ProtoDUNE-SP was used to perform design validation on more than 100 boards that
were cycled and tested at LN2 temperature. No failures were seen during these tests. ^-- No cold tests needed?

– Imamingeering Inc. – PSL Part# 8752702 Rev B – Quote# 858432 – Why 1 part, not 6?
– Mill-max part no: 0307-0-15-15-30-27-04-0 – https://www.mill-max.com/products/receptacle/0307/0307-0-15-15-30-27-04-0?s_term=0307-0-15-15-30-27-04-0&s_type=Quick%2FProduct%2FPart+Number+Search – 40 per APA
– Protolabs? – PCJGB17 – 0401?
– Gray epoxy 2216 by 3M – 2oz packages? – https://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Scotch-Weld-Epoxy-Adhesive-EC-2216-B-A-Gray/?N=5002385+3292667630+4294940354&rt=rud – Epoxy Gun – https://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Manual-Gun-for-2-part-cartridges/?N=5002385+3293193962&rt=rud – How many of each will be required? Apply by hand or automate?

Boards, toothstrips, and pins Materials that stay in the board (epoxy) Jigs, benches, etc Consumables
10
– Plenty of room for work and storage – Existing (but currently unused) equipment
needs to be moved out
11
– Inspections, and cleaning – Epoxying – Pin setting – QA/QC – Packing for shipping
– Jig building, and other startup tasks – Tooth strip cutting
– No one explicitly available, but can be found if needed – PSL docs indicate 2 hrs / APA for foot boards. What is actually required?
– Oversee board factory operations (hiring, scheduling, supervising, etc) – Paid for by the base grant … assuming I get funded :^) – Base grant application this Fall – Plan to ask for:
43.3 = 2 x (26.7 - 5)
12
15.1%/21.7%/21.7%/21.7%/19.8%
– APA production schedule – Preferred stockpile at each site (min/max?)
sites for other (similarly installed) boards
