We have been using Coilcraft 1008CS inductors for several years. We have had problems with them turning green when we use lead-free solder paste. We have tried several solder pastes (water soluble and no-clean)from different manufacturers, but the

Hi Ive checked into this a bit more, there are two coatings im told you can get one is a teflon coating that you paint on then bake, the other is a red oxide (lead free) paint. Also if your using solder pots and they are close grain cast iron they a

I worked for a EMS who makes Medical Device Electronics, and yeah, the FDA's methodology for validation is a complete cluster-fudge! They did it on the principle of...does the shop air going into your equipment REALLY 80 PSI...or is there REALLY 220

My company is looking to run some small validation cards to verify our Pb free process for potential customers. Basocally, we'd like to print a small card, place some components, say 0402 to a small BGA, maybe some thru-hole stuff, and reflow it. So

You have 2 groups giving us 'evidence' here: 1. the research companies who will do anything to scare us, just to make sure more research will be done, if they said everting was fine they'ld be out of a job in a sec. Ex: look at that paper, a leaded

The Novastar is primarily a low end machine made in India, I think. Technical Devices is more comparable with other dedicated wave soldering machine manufacturers. I recently got a good deal on a new TD machine with a Titanium Pot and Pump. It was

Kevin, Thanks for the reply! I haven't had a chance to see the Novastar. Now maybe I will save myself the trip. The TD rep is trying to contact someone close by so we can go take a look. I am definetely leaning towards TD because they have worked f

So, if 45� is theoretically optimal for aperture fill, but 60� is better for defining fine pitch bricks, is 52.5� the best compromise for an all around design, or does it not work that way? I see blades with either one angle or the other but with th
