Using IR,
I saw these items about using IR for reflow and I was wondering of anyone
was using laser IR to solder down the leads of a gull wing or chip resistor.
My experiments with CO2 lasers (10.6 um) shows metal reflects the IR while
the substrate (FR4) would absorber and burn.
Has anyone ever used laser IR soldering? Any info or links?
Thanks,
Bob Kondner

We use a focused IR from PDR. It is very good.
We use it for BGAs, CSPs, QFNs and just about everything else.
We had it upgraded to use two IR sensors for profile control and
background heat.

Technetters,
We are shopping for a anew and improved BGA workstation. First of all it
would be great if I could get some recommendations what you have
purchased recently and why. In addition, I was hoping someone could give
us some real world pro's and con's with respect to the focused IR type
of workstation.
Thank you!
