Adam- Mikie here. I too am placing 2 PBGA sockets on an assembly but they aren't mirror imaged. Thanks to the SMT Gods for that one. You say you added more paste to solve for open solder. Do you have x-ray? Were the alignments perfect? Also the part

When it works right, it's a beautious thing. => When goes wrong, you have one board with some of the other board's material, not too coo. Scribed and broken ceramic has bad-butt sharp edges. You'll feel this sticky stuff on your hands, look down,

On the equipment: * Placers: Look at MIMOT and Europlacer as other possibilities * Printers: Elite may be able to to the job * Oven: Maybe RI? Alternatives: * I understand for contractors: (1) Giving-up a job is distasteful (2) Success with new cus

Hi there, I am a bit late in answering the question about removing (and probably replacing) those d&%&$Z3 Mictors. Are they straddle mount or vertical? How many segments? What's the configuration of the board (PCB thickness, adjacent components, part

I have oftened wondered how this industry lets its workers get away from being responsible. The best way I know of is to have them buy their own tools. Just take a look at the trades - carpenters, plumbers, welders, sheet metal men, body repair, mech
