We like to use "enameled wire" that can be stripped by hot solder. Formvar [105�C] will not do that. Formvar was designed to with stand the hot oil seen in transformers. So, it requires either chemical or mechanical stripping. Most polyurethanes

http://www.mgchemicals.com/products/832.html Loctite makes a version too, if I recall. Designed to be tamper evident, but yes, rework is a bear. We had similar results using one of Lord Chemical's urethane potting compounds. It was a filled black fi

Steve: Thanks for all your contributions to SMTnet. It just goes to show that geologists aren't as bad as they say. Since we can't pillage your office as you're walking out the door, before you leave, would you send all those design standards that

" few software bugs"....many software bugs. May I remind you of version 6.10, 6.32 and the still-born 6.34!!! MPM has worked very hard to repair these, though it has taken some time. I have 5 machines from the SM Tech era, mpm500 and mpm1500 era (v

Hi SMTAnet, SMTnet, You already got good answers for how to go forward. I believe that this 50mils is a remnant of the days when we started at 125 mil grids and started the process of going down to 100mil grids, SMT. My gosh who would ever want a 1

Help! We currently use out SMT for pretty much one-off's. we use BGA's and complex board designs and it looks good to say it's been SMT'd. We are now looking to take on a project (a one off project) that would move our production up from 1 to about 2

Our design team have got a problem. We need to either drill out 6 vias/pads for a BGA site, or remove the solder balls form the BGA before they are palced. ( std eutectic) Has anyone used a vendor to remove balls from BGA (0.75mm piutch, ball size ap

Hi, Does anyone know of some good software for managing component consumption in manufacturing and keeping track of what products use what components, and the consumption rates over time. This lets us forward plan component orders for future product

I've got lots of questions: 1.- What kind of support are you seeking? - Web URLs, books, technical advice, etc?? 2.- What is the scope of your project - an audio system can be small or huge? 3.- What are your technical specifications (watts per chann

For a general rough rule of thumb I use Practical Components for programming our machines. Practical has a nice layout of most Tape and Reel components and sizes. We use this mostly for tape/ feeder allocation. But for QC, Specs, and Other Stuff we
