[halla_compton] [EXTERNAL] Re: e-detector QWAD adapater Fwd: FW: Assembly quotation for order W73507AST5

Mon Oct 28 13:09:59 EDT 2019

I am still trying to figure out how to ask for a quote from
https://urldefense.proofpoint.com/v2/url?u=https-3A__www.4pcb.com&d=DwIFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=_AZDZC82sWbwXJj9HzNlSmTTeMqubje6LM_Ugflg5bU&m=bIswPueKntxLn2esZOQ62JqYIPfBW0pJZ61b0VRolIc&s=cs6xSErjoKCbkpMyVXGUUe_5D5IlIq8MSu_7vAZGOT0&e= . Maybe Jie could register and ask for a quote.

maybe you can ask for a quote and the turn around time. I was told 4 days
should be around 600 $ or so. Though 2 weeks does not sound too bad.

By the way Juliette has a thin silicon, I am the one who has the only 1 mm
plane ( which is back in the beamline right now ).
