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

Billy, I have to disagree with you. We inadvertently soldered a Pb BGA with SAC305 paste and then had it micro sectioned and spectrum analyzed. Imagine our surprise when we saw the spectrum analysis showed Pb. The micro sections showed none to ac

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

"45* is a common angle of attack. Squeegee blades are commonly manufactured at 60*. The combination of the angle of attack and the blade angle results in an actual printing angle between the two due to down pressure and flex of the blade." Ahhhh, so

The company I work for has been looking at pick and place machine from three or four well know manufactures. My question is. Is it a buyer market right now and what is the average or a common discount people are getting on equipment?20%,30%, etc. See

Hi Rob, They want you to think that their products are subtly different & that they are not interchangeable, although they are in nearly all cases (this is different for high frequency RF design). Also your layout guys aren't going to love you wi
