Please, don't give em' a soap box to preach from. Now, back to No-Lead. Has anyone else out there thinking about the higher emmisions you're company will pump out due to higher temps? Just wondering. I can see the "No-Lead Brain Trust" sitting ba

Opinions. I have a large finned heatsink that we place over a D2pak transistor. This heatsink is designed to heatsink the transistor through the junction of the pad area that the transistor is attached to. The paste pattern we chose was small dots ar

I would agree with JAX for a general estimate. If you have a few specific boards Universal can put them in a simulator and give you pretty close estimates. I would reccomend you go to thier NY facility and actually run some boards and get to know the

Please leave some feedback after you get your machines. So far, ours are running well beyond our expectations. I did not get much feedback from users here though when I asked about them before we bought them. Although we had little feedback, we had n

I agree Rob, The main thing is that you don't beleive everything without question. If you're sure the supplier knows what he's doing and you have a good relationship with him then a declaration should be OK. When doubt arises it is worth getting sam

Do not believe every thing your suppliers tell you, even a written cert does not guaranty compliance. We recently purchased a Niton XRF analyzer. The first day in use we found component�s that were made for us "RoHS" that were far from compliant. Peo

Good one! I remember at my old company, the auditors, both internal and external would go immediately to the refrigerator where we kept our glue and solder paste and then they would spend most of their time there, because they were afraid of all of

Sr. Tech, First, thank you for the great laugh! Second, I always go for that 'deer caught in headlights look' that they get when you start asking your questions. As a caveat, I have learned to slow down when they start drooling out of one side of

There are several life studies (see for example http://www.solder.net/stencilquik/articles.asp) which point to higher reliability of reworked BGAs using solder paste vs flux. The theory on the mechanisms which allow this to happen are as follows: 1
