If the equipment was originally 'quad'....then....they had already had some spec'd out for each machine. I would try calling them and seeing if they still have the 'old' documentation. If that doesn't work....you could try any reputable company that

Pure ignorance is my answer to that.... You're with a CM, right?? Your idiot customer probably has never stepped foot on a manufacturing floor in his entire gott-damn life, but.... he reads SMT Magazine every month, and probably read some article

I wonder if you have any experience with mating 760 to 730. What about suport for 700 series? You have 760 still running good.How many years they have to service machines after purchase. Is the 2060 significantly better than 760 regardless capacity?

Assuming you mean paste and not adhesive, we use both wet and dry with vaccum. We can control the solvent thru the software for each job, so no solvent sprinkling thru the stencil. Never head of corrosion on stainless steal, but then again I'm sure

We use immersion Silver for all of our lead free PCBs. They come in the "silver saver" paper you speak of and we have found that they will tarnish after 7 days in the open enviroment. Even with this tarnish we experienced no reflow problems. We are

"And don't look for logic or consistancy in polital matters". No kidding? I am having a hard time trying to figure out how you go about determining your levels of waste and also where to find "hazardous material" classifications for my area. I am

Hi. I was curious what some common accept/reject criteria would be on copper wall thickness. For instance, if 1 ounce copper is used, I believe the IPC specification is 0.001" minimum thickness. Should the order be rejected if there is one measure
