We are high mix low volume company and we use a MYDATA TP9. Very good machine that can place 0402's effectively. Issues we've had include: Maintenance - It is an older machine so, it has needed a little more than I care for. Cost of Feeders and Maga

Guys, Solder paste height worries all of us as we encounter the non wets after reflow. More so in fine pitch QFP's. The non wets are not always caused by solder paste height. Many other contributors. Even the pad geometry on te board can contribute t

The Advantis with a lightning head is less accurate at chipshooting than a Fuji CP643. That's progress? Yes it is a great platform for it's space & yes it is a good all in one package, and the IC aacuracy is far better than stated. But you run o

Paul, I'm quite frankly relieved, I thought I was the only one with these thoughts! We have only had our Rheometric pumps since February, but since then our process has been difficult to control with fine pitch applications. And then there's always

If it were other machines I would suggest the possibility of air kiss blowing the solder away, but mydata's have a release to make sure the air kiss never gets too high. Unless it is not pointing 90 degrees away from the machine like mydata recommend

Hi Jaya, Here's a definition, towards the bottom of the listing... http://en.wikipedia.org/wiki/Fiducial Mainly, a 'global' fiducial refers to the outside of the board, usually on the scrap rails. This allows the machine to locate two reference

EMI shields are no fun! Your process will depend on your design and condition of the shields. We always break the shields into their own process. Because the shields are never flat, screen printing paste and trying to reflow them only caused huge

Yes, yes, I agree with American man, URL, on all his points about having to know the overall process 1st. I'm surprised he doesn't have his own free consulting website. Other things you can try are: * "Dog-bone" apertures... taper down the apertur

Hi Rob, We encountered it on a 6x6mm device, hence, we could consider it as fine pitch. I suppose that it may also have something to do with improvements in the speed of the feeders. Honestly, we don't have that visibility bec our customers do not

I would use an SPM if it was my choice(for a semi-auto). You should be able to get a used one with vision for less than 10 grand. I would not use one without vision for fine pitch, although you probably could get away with it. The first few they made
