Hey pr...sure it's warm there, but I also hear that in that area where you live it's not too uncommon to have a kiddie pool in the front yard (with a couple of darkies in there), pickup truck parked on the front lawn, chain-link dog jails, with you o

Headers and SMT

Electronics Forum | Tue Sep 29 11:37:52 EDT 2015 | robl

Hi Marlyn, We use durastone pallets over a wave - so areas machined out so the solder can get to the pins but not the SMT. You can also get fancy selective solder machines, but I'm guessing that as you're asking you haven't got one. Hope that help

Touch-up and Inspection Process

Electronics Forum | Thu Mar 03 11:49:23 EST 2005 | Rob

Doesn't that depend on your company's culture & management style? We (and I feel slightly dirty using this word)empowered our end of line inspection/touch up people & trained them to know what is good or bad - so issues can be immediately fed back,

Yes we do have a problem with this. We have by now investigate numerous lead/RoHS PCBA:s The RoHS boards are by far the most difficult one's to probe and test. Our people at the "test area" including Flying Probe and ICT they spend a lot of time to t

Conveyors and bar code

Hi, We have two complete SMT line and in this department we use conveyors for board manipulation. Concerning the wave area we are not full efficiency and I have to look for conveyors and bar code reader to make board manipulation an automatic proces

Dye and Pry

You can say: The pad was lifted after reflow and prior to the dye and pry failure analysis. When we see lifted pads, we think: * That's a good solder connection * Either it took a lot of force to lift that pad or the fabrication of the board in the
