Hey Guys.
Quick note about 100 Pin QFPs - ALWAYS clean them after soldering! I had some odd issues that I just couldn't find. Seems some Brakleen (Pep Boys degreasor) and a toothbrush did the trick. I wash the PCB and CPLD and then brush each side of the CPLD pins twice. Then some compressed air to finish the job. The Brakleen evaporates and leave zero residue.
So make a note and add this procedure to all 100 QFPs you solder.
