I had very little luck soldering fine pitch packages until I watched this video:
I ordered one of those Hakko well tips (correction: bevel tip, as patent crap attempts to prevent the well tips from being sold or used in the US) and a box of kim wipes from All Spec. My delivery came in today.
I tried this for the first time tonight on an SMD kit. Processor is an ATXmega32 with 0.8mm lead pitch (on the large side of TQFP packages but still pretty small). It took me less than 10 seconds to solder the whole package. The iron spends so little time on the board, you barely need to be concerned about heating anything up too much.
Attached is my first attempt at this (that’s a quarter in the background). It’s just about fool proof. My result isn’t as pretty as his, but it looks good to me
I did it as close to the way the guy in the video did as I could:
[ulist]Clean the board with alcohol
Flux all the pads
Tack down opposite corners (I used regular solder, he used paste)
Flux all the pins (I used a flux pen, not the syringe he had)
Load up and drag relatively quickly
Clean up with kimwipes and alcohol.[/ulist]
I didnt have any bridges, and only one tiny horn on one pin. It was quite a bit faster than soldering a big DIP package. Im sold.
I’m also giddy
