Dear all, Referring comment from Mr. Jack,IPC director certification & assembly technology, the term "fillet tearing" is too broad. Cracks or fractures in the required fillet area, with SnPb or LF alloy and whether you call it tearing or not, is a D

Get-out the razor blades, bud. You could run that sukka for 6 sec dwell, cook breakfast on it, and you still will not get fill. [Hole file that is, breakfast will go along ways if peckish, though.] You could fire-up the depleted ozone rework gun [

| I'm trying a second time to post this very important message, to me, concerning Air-Vac's following creation. Does any own and use this stuff successfully to remove solder from 20 layer and up MLB's with .020" diameter holes? Also, is any of the ad

Selective wave selection

Electronics Forum | Mon Apr 01 19:57:07 EST 2002 | davef

Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

hi, NEMI recommends separate solders for reflow sodlering and wave soldering. Reflow soldering- Sn-3.9Ag-0.7Cu Wave sodlering- Sn-0.7CU Wavesoldering- Sn-0.7Ag What will happen if a mixed technolgy PCb board containing both through hole and surface

http://www.aoisystems.com/ I was at the SMTA show and saw this company's booth. It looked like a good product at a good price but it doesn't do 3D AOI. The sales person was saying that 3D AOI is only useful in cases where a lead pin is hanging in

Hey Kyle - Good for you for pushing your horizons and considering pin-in-paste (aka "Intrusive Soldering"). Don't let the nay-sayers out there discourage you. When I encounter mixed tech PCBAs (SMT and through-hole) my first choice, if the design a
