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

I have to disagree with you, BillyD. If Craig searches the forum, he will see that the concept of a Pbfree BGA with SnPb paste has been debated many times. You say it is fine. I say it is NOT. There have been several studies done that clearly sho

Hi, We have been soldering lead free BGA's onto products with lead based paste, and we have had no increase in defects at all. We have used a standard lead paste profile, so we are not altering the temps anything from what's recommended by the paste

Hi Jay, Concerning you PCB, what TG do you expect to use for your lead free process? On my side I have a problem. I order PCB from Canada and from China. My PCB vendor in china is producing a lot of OSP and ENIG PCB, no HASL lead free and in Cana

Hi russ, I am in the process of developing a "hybrid" reflow profile to solder a board that has LF BGAs and leaded solder. Have you encountered a similar situation before? if so what was the "safe" top side temp for the leaded components that was set

yes! i though this thread looked familiar! looks like it has been repeated....even the response from muse is very very familiar...that, or i am have a serious attack of deja vu! thanks for the requote though.......by doing some research I decided to

Amol, I thought I answered your question in another thread, dude! Anyway, to re-iterate. Yes, I was able to pull it off a hybrid profile. The LF BGA passed tensile testing, but no, it wasn't thermally cycled or stressed first to expose any latent

Out of curiosity, what flavor lead-free paste were you using? That's also going to affect the profile.

Doesn't the components and PCB need to be lead-free also to be a "true" lead-free process?
