Desoldering a TQFP without a desoldering tool...heat the pins up, bend them up with something. If it's not the chip, you can probably resurrect the chip by laying it flat on a suitable spacer and flattening the pins back down with a toothpick...works for me anyways.
Yep, in Minot. You guys sent us this Alberta Clipper! And it rocks!!! Radio is saying -15F with -52F windchill (whipping up out there about 25-45MPH).im in Calgary, and its -42C with the windchill and im workin outside...
Personally, I use www.pcbexpress.com, but that's only because I've got an older version of Protel 2.7.5 and they support it. If I only had Gerber files to work with, I'd probably go with APCircuits.Alberta Printed Circuits has a prototyping service that is two boards....
Get one with an internal OSC option, like the 18F6723 or something...unless you need the CAN option. Incidentally, it's really easy to overlay an 80pin TQFP over the top of a 64pin TQFP and give you both options. When I made those 80pin TQFP -> dual 40 pin/IDC adapters awhile back, I did exactly that...made the center of the PCB able to take either an 18F6720 (64 pin) or an 18F8720 (80 pin)...same layout, just added 2 pins at each end on each side, spacing still the same, etc.etc.etc.so i might pick up another PIC and try it all again just in case i shorted something or the PIC is bad...
