...don't expect high yields with hasl on that device. Yeah, you an do it. But not reliably. Also, factor in board warp, bump tolerance AND HASL variation....recipe for disaster. can your process toleate a selective gold on the one device? How ab

I was wondering some input on what to use for measuring height on our solder paste for SMT placement. Is there a place to buy a machine or a scale in which you can use? I know in the past I have used a laser scope at another facility but where I am n

The best solution is to use a software tool which offers program optimization, feeder set-up and line balancing even if different machine types are in the same line. Check out the leading solution provider: http://www.timmsweb.com In my view, your

We are currently reviewing a design which has a leadless chip scale package with a solder thermal pad on the underside. The application notes for the device specify use of a no-clean solder paste as the gap under the device will prevent cleaning. Is

I've been the AOI programmer for around 5 years now. The equipment I use is the Orbotech VT-9300 & VT-9500 systems. The programming isn't too difficult, mostly Grey-scale shadow measurement through application algorithms. Three levels of lighting an
