So today I soldered my first surface mount component - a PIC32 100 pin TQFP package with 0.4 mm pin pitch. It was perfect. I would post pictures, but unfortunately, my camera is damaged. I did it with a simple radio shack soldering iron, liquid flux, copper desoldering braid and a TQFP adapter board. I first put liquid flux on the adapter board's pads with the flux applicator pen. Then I placed and aligned the surface mount component on the pad. This was the most difficult part. I then put some tape on it so it wouldn't move around and soldered a few pins to hold it down. Then on the opposite side I used the drag solder & flood method (albeit easy on the solder) and continued the rest of the way - all around the chip. Some pins were bridged - so I took some handy copper desoldering braid (this stuff is awesome) and dragged it across all the pins with the hot iron. The excess solder was effortlessness absorbed and I was left with a cleanly soldered 100 pin 0.4 mm pitch TQFP component! Some of you may believe that I tend to ask too many questions regarding seemingly simple topics such as PCB etching or surface mount soldering - but it helps - because I got it perfectly the first time - no mess ups. Interestingly enough, when I did my motorcycle insurance course, the instructor assured me (and was willing to bet) that I would drop the motorcycle since I had not driven one before (but had studied it carefully beforehand). Needless to say - I didn't drop it at all - or lose control. I didn't take the bet though :( I just hope this trend follows through till next week when I etch my first PCB :) Next up: etching a PCB for the PIC32 on a single sided copper clad board. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
