Another option is to cook the boards in a skillet. http://www.sparkfun.com/commerce/present.php?p=Reflow%20Skillet
While John may be brave enough to hand solder BGA I am not :-) Shorts can be easily detected with x-ray, but opens can be quite difficult to spot. If you do endup hand soldering BGA, this is a good tool to check shorts and opens. That is, if the part is JTAG enabled. http://www.macraigor.com/jscan.htm -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Miles Sent: Monday, June 02, 2008 7:27 PM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] PCB design questions thread II > Quoth Bruce Griffiths at 2008-06-03 09:50... > > > How do you cope with SMT parts (eg high frequency ADCs) with metal > > thermal transfer /ground connections under the package itself? > > Haven't done it myself, but interested to hear others experiences.

Solder paste + heat gun does the trick, or you can just carve out a hole for your soldering iron tip with a Dremel tool. Even BGAs are commonly soldered at home with toaster ovens. -- john, KE5FX _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
