Matt, no matter how extensive the PD library you get with the different Fuji systems, you will still have to tweak some of them. But there's something you should lock in your drawer, the caliper. Why using it? The most accurate data is in the data s

Okay, so my boss gives me this little "side project" that nobody else wanted to do... ....our Component Prep area (an area that no Engineer wants to support) is in need of a thru-hole component counter - counts both bulked and reeled parts. They ha

Yeah, 0201's are real buggers to deal with, as the components are about the same dimensions as the PWB tolerances. Probably a good start is the paper I did with Plexus Corp., available on www.plexus.com, under the "In the News" heading. Headlines: -

Not to toot my own horn, but ever since I came on board at my company, wave solder defects have gone down by 35%. This was due mainly to a new flux and a process control system that I implemented back in '99. Now, the metric used was DPMO. How do
