Ultrasonic I understand maybe the best at cleaning stencils, but we use a "pressure spray" it works very well and only takes appx. 12 minutes to wash & self dry. Alcohol is the cleaner, but there are several company's making detergents for cleaning

SmartSonic states that they will not sell their 440R chemistry unless it will be used with their machines. But to answer your question, the following manufacturers make ultrasonic stencil cleaners compatible with 440R and many other chemistries. Aq

Genny, Xray systems ( or at least what I have seen ) are a manual based system. That is, you put the board on the machine and look at certain locations that you want to inspect. What we have in mind is an automated system that will catch obvious, no

AOI technology is over-priced and inconsistent...lots of false errors. Your best bet is a paste height measuring device (3-D) Cyberscope makes one for 25-30 thousand. This process is really only necessary for high volume operations. As for you questi

Why measure solder volume? I believe if one understand the process well enough, the effort should be spent on area that will gives better indication of your solder printing process. From my personal experience, a lot of auditor knows little of the pr

There is no test. Beyond the issues that you mentioned that affect shear, an article published in a recent [1/01] "Journal Of Surface Mount Technology" documents that shear is also dependent on the rate of shear. You may be able to contact the auth

Sure, researchers measure shear as an element of their material characterization process, but that does not make it an acceptance test. [Truly, this conversation is not uncommon on SMTnet. So, it would not surprise me if an enterprising something o

I have several carts at my facility, i think we had our machine shop make them a while ago, we can store loaded feeders on the top portion and we can store several screens on the bottom. The idea is to have the days production, if two jobs or more,
