we had many problems with this. there is no standard that I could ever find. we came up with our own after weeks of headaches. we use 25% as our guide line we use window pain only for the center paid to allow for out gassing and reduce 15-20% globaly

Guys, I need to set up a new SMT line. I already got a refurb DEK 265 and Vitronics XPM3 reflow. I currently use Siemens but is getting really expensive (spare parts, service, upgrades, etc), I'm thinking Universal, Panasonic or Assembleon. Can

If the concern is the increased moisture absorption associated with lead-free capable materials, you probably have the most experience with phenolic materials like Isola IS410 or 370HR. The best move would be to switch to an IPC 4101/99 or /124 mate

We wound up using a ramp to spike profile with 50 sec. between 150C and 217C and 90 sec. above 217C. The idea being the flux is still active when it hits reflow, and it stays in reflow long enough for the weird alloy in the parts lead to wet. All par

Does anyone have ballpark figures readily available for how much conformal coating machines cost? Benchtop and In-line? New and Used? I am really curious and considering purchasing, but don't want to go stir up a hornets net of salesman at this po

sipad does work we used it on one assy it had a very fine pitch part on it and at that time our dek 260 wasn't up to the task along with our 8 mil stencils. we had no problems with it it was sticky enough to hold the parts on thur all smt machines.
