Hi all, If i know my field conditions and the required lifespan of the final product, how can i decide what thermal cycle to use for ATC to qualify the product?? I have the JEDEC standards for min-max temps and dwells, but how do i translate them int

I agree with Dave 100%, ATC will expose the board and components weaknesses and potential design problems and/or the need for conformal coating. The life span can only be predicted and/or extended by well-documented field failure analyses history and

Thanks for all your inputs. As I read through your responses, and through my research on the web, I have learned there are so many options to try and evaluate. The material we are using is loctite FP4531 - a snap cure flip chip underfill. Loctite ha

In other words it should mean that Lead Free Soldering Process (this SACs era, and not for istance classic Lead Free Sn/In used since many years ago) is still a "Baby Technology" and so we need experience and feedback from the field before to issue

We have an SPM with manual vision. Its the best manual printer we have ever had. I believe you can get one used for around 10K. If you buy a realy old one, make sure it has the air table lock!!! I think they only made a few that didnt.

Good ol'Wenesco. That's one of my old products they have in their advertising. The tricky part about dip process is in the fluxing. Spray fluxing a populated board from the bottom looking up can be a challenge. You'll notice the areas you missed
