There are plenty of studies on this subject. If the BGA can handle the extra temperature and they are soldered on a leadfree profile, the general result seems to be a better reliability than Pb :) Just out of the top of my head, there was a link to

Hi, That's a really interesting article, however one thing I am a little confused on. They seem to say a Pb-Pb solder joint is almost as bad as a Pb-lead free joint in their results. Are they saying the testing which looks like it cycles up to 125 D

We all know those academic 'reliability studies' are very focused and only give a snapshot of real life. The real reliability studies of leadfree are starting as we scramble to meet our numbers. We have no idea about your customers' expectations ab

Oh yeah, I forgot about the great big burn of 2006 you and davef laid on me. Wow, good one fellas. Now high five each other. Don't forget the butt slap. Now belly slam! (wow 578 lbs of flab just met in a cube somewhere!) Rub each others bald spo

I certainly would not buy off any product from a manufacturer that is for sale. Imagine they have known they were going to do this for some time now and all of the cost cutting and apathy that is occuring at this time does not bode well for their cus

Yes, this board is approx. 3" x 17" x .062"T with large areas of ground planes. However, the delam. does not seem to be confined to the plane. We also see it around component pads and fiducials. Generally speaking, it could be said that the first

SWAG - I also forgot to mention a few things. Our delmaination was always between the large copper plane and the laminate. It is a multi-layered board, so even when the delamination appeared around components (through visual inspection), cross-sect

Get over it guys. China isn't going anywhere and it would be too late to do anything about it now even if someone could. It's our own fault for this anyways.......and I mean as consumers. In times when we demand free cell phones, PC's for $100 an

G, it is called, "I just went to a sales seminar on pbfree" Show them your profile and call them to the table. Make them tell you specifically what is wrong with your profiles. and even better yet make them explain to you why the extra zones are

What we've seen is more heated length gives you the ability to run the oven at a higher chain speed. Notice, heated length... not # of zones. Needing to achieve higher temps at reflow can cause you to have to reduce your chain speed. For l
