I want to solder one TQFP144, but do not have any experience with anything more than DIP40.
This is what I'm planning to do. I will:
- apply some tinnol on all the pins on the PCB
- remove excess tinnol with dump cloth
- place the chip and solder it pin by pin with solder iron
step 3 will certanly solder several pins together which I plan to fix with solder braid. The question is: what width should I buy?
