Most likely either profile or I was thinking a cap! resistors are to thin to make the part stand up hehehe just a joke. Do not follow the advice of weighting part, that is ridiculous, poster of that, if you have never done BGA before please do not

Rohm make them & call them Backfires: http://www.rohm.com/products/databook/led/pdf/sml-812.pdf The only problem is on some applications you may have to use light pipes.

I have two gsm1's and I don't believe the current software can do this. Assuming you are not importing cad data, that would be the only way.

DEKs are the best. They blow all others away. Sure the Pro-Flow does tend to waste paste, and you do get some blow by, but once you realize you have the best screen printer available, you can live with trivial things like this. Squeegees are for i

Hi Vshan, Have more pallets made, and don't stack them - lay them flat on a trolley and move them back to the start of the line.

Russ is correct. We have been using SAC 305 for SMT and SN100C for wave and selective and repair for about a year. May switch to SN100C in SMT at some point if we can get some paste that wets better.

We have been using SAC 305 for reflow and Cobalt 995 (very similar to SN100C, only cheaper) for wave and rework for quite a while now with no issues that I'm aware of.

If you think you are having lighting issues, you should do a histogram test. It's under the test user. There is a pot on a power supply that will adjust the brightness. The power supply is right next to the Y axis motor. There should be a brown p

Your DEK could read non-blackened fids? Wow, you must have bought them from Superman. Or did you just teach baord pads and stencil openings?

The E5s I had just needed the fids to be burned black. Never needed epoxy, although we did have one stencil that we had to touch up with a sharpie now and then because they didn't burn it dark enough (too hot...?).
