David: How about starting with MCMs? IPC docs are: * 2225 - Sectional Design Standard for Organic Multichip Modules (MCM-L) and MCM-L Assemblies * DD-135 - Qualification Testing for Deposited Organic Interlayer Dielectric Materials for Multichip

I have just purchased an EMC CyberClean Series 1000 stencil cleaner(jet spray non-rinsing system). I will be using it to clean misprints, stencils, and residues off of completed prototype assemblies. We are strictly a no-clean process and was looki

I would recommend Zestron's Vigon SC200. It does not require a rinse as long as you cleaner is equipped with a wash solution filter to filter out the solids. Zestron # is (888) 999-9116. The toll-free # is frequently busy� If so, try (703) 589-11

We used to use those, back in the bad old times. basically, it's a router with a blade on it that is used to trim the leads of PTH components that are mounted on boards. Nasty process. Difficult to control. Messy, firing cut leads all over the plac

Several of our customers use our Summit series equipment for this purpose. Our rework stations are used in proto labs to prove manufacturability. Consider it a low volume, semiautomatic pick and place and selective soldering reflow oven. Some low

Advanced electronic assembly convection reflow ovens include a variety of options for cooling product after reflow. The Electrovert Omniflo series ovens include options for internal or external cooling systems. What are the pros and cons of utilizin

Have you thought about an AOI system? With the system we have where I work, I'm able to run queries that'll tell me DPMO, yield, and pass/fail rates on a board level, part level, and opportunity level. Furthermore, this data can be broken down to see

Hi Dean, Thanks for the feedback. I suppose I should reveal the nature of my query. Contact Systems was founded by my father back in 1970. I worked there from 1983 until we closed the doors back in 2009. I acquired the assets and intellectual pro

First, on your reflow temperature comment: The 183*C focus for reflow recipes for tin-lead solder is a falicy. If you held a recipe for tin-lead solder at 183*C peak, it would never reflow. Recipes for tin-lead solder need to be at liquidus plus 20*C

I've heard of a series of labels that absorb moisture at different rates and/or change appearance when a specific saturation level is reached. If such labels exist and if they could be correlated to the exposure limits of specific moisture sensitivit
