QQ-S-571 was authored by US Gov. and administered by Hugh Russell out of Defense Supply Center. Note that the QQ-S-571 and its associated QPL were cancelled (without supercession) ~6/15/95. For internal procurement, DoD users were directed to IPCs ANSI/J-STD-004 (liquid flux), 005 (solder paste) and 006 (solder alloys/wire/preforms). =============================== Jim Maguire Senior Principal Engineer Boeing Defense & Space Group PO Box 3999 M/S 3W-97 Seattle, WA 98124-2499 Phone (206)657-9063 Fax 657-8903 Email: [log in to unmask] ================================ > ---------- > From: Robert Schetty[SMTP:[log in to unmask]] > Reply To: TechNet Mail Forum.;Robert Schetty > Sent: Tuesday, October 21, 1997 10:46 AM > To: [log in to unmask] > Subject: Re: [TECHNET] Assembly > > Hi Charles, > > Thanks for the information.
