How about graphite coated wires or bar? If there are such things

I am trying to put a center support on a wave solder machine for lead free soldering. My problem is that every metal I use is interacting with the lead-free metals and thus eating away the center support. I have tried titanium, stainless steel. I am

Sn corrosion effects were studied for stainless steels, coated stainless steels, titanium, cast iron, and other materials. This study can be found in the SMT Library under "Equipment Impacts of Lead-Free Soldering" Electrovert uses a Melonite coating

Try: Tungsten, tungsten carbide, ceramics like boron-nitride or how about pyrex glass? Glass blowers could make "hooks" that connect to a cross bar. I would NOT use aluminum (even if anodized). Try stainless steel 316. 303, 304 do not have enough

I would try a PTFE (Teflon) wire or Teflon protected wire or you could try anodized aluminum. Its getting more and more interesting how the lead free era develops. Just a thought I wander how long its going to take the tin (not passivated with lead)

Well, you won't win any IPC awards for doing this. Another idea is to use a center punch to create the dimple you need. It wouls be quicker and you won't destroy the barrel like you will with a drill. Don't ask me how I know.

How are people getting BGAs reworked on boards that are 15"x15" at .06" thick? The BGAs are pretty much in the center of these assemblies. We have just received these and I cannot keep from warping/bowing as much as 1/2" at the heated area. Our bot

We just got a contract to build a board with 1400+ SMT placements. This thing is 16" x 12" and the PCB thickness is 0.142". Dead center is a 580+ pin BGA that costs about $600. I'm a bit intimidated... I've done lots of mole profiling on BGA's bu

| I'm trying to find a source for a tilt device for use when doing touch-up soldering. Employee needs to raise the board above standard bench height for better access to the board and for better posture. Angle of the tilt device should be adjustabl

Hi! We have a dek 265 gsx printer. And we have a problem with it. After determination of fidutials it puts the paste differently. Sometimes it puts senterline, sometimes left of center and right of center. We can't identify the problem. Could you pl
