0402s and below kill me. I did a bit of time doing rework in the 90s and controlling solder on such a microscopic scale is an absolute bastard. its ok placing it first time but if you screw up, life is pain. Never tried a BGA and never want to. They're pick'n'place territory if you ask me.
- HeyLaughingBoy 14y agoI have to agree. The day I need to do an 0402 is the day I seriously start looking for a used P&P machine.
- DanBC 14y agoI couldn't imagine doing 0402 by hand. For people who don't know, 0402 is 1.0 mm x 0.5 mm (0.039 in × 0.020 in). Using an oven to solder is nice because it's mostly self-correcting. The melting solder pulls itself to the shape of the pads and also pulls the components into correct placement. (With a bit of luck). Hand soldering SMD components wasn't ever one of my skills. (And my through hole soldering was, if I say so myself, pretty good.)
