Hi Eng. Yumex in our company we're using 9 zones air convection oven. When the technology on Lead Free came along conversion from non-lead free to lead free viceversa was frequently done but there's no problem on contamination. Where is your company

Thank you for the reply. We do build SnPb assemblies as well as Pb-Free. I am aware of the Silver paste. However, what impact is there with reflowing SnPb components with a max temp of say 220C when using the higher Pb-Free temps?

I was asked to try and find us some good Lead-Free soldering Irons, I know all Irons are "LEAD FREE" I mean I need to know if anyone has any recomendations for an Iron with really good recovery time, that is higher heat capable. For a price that isn'

When the component suppliers specify the cap as no more than 50sec (or even less time)above 200C, is there any way the lead-free profile window will fit if we wil have to achieve a peak temp of 230c for at least 30sec for the lead-free process? maybe

Are you using lead or lead-free solder? 260C would be good for lead solder but may be a bit low for lead-free. We run our lead-free selective solder pot at 300C although we do not have any pre-heat or top heat, just hot nitrogen blowing around the

I totally agree with you when whe talk about a lead-free process. In my early comment I thought we were talking about a tin-lead process with the pcb pb-free, when the solder paste limits should be respected. That is the motive the temperatures I sa

Hello Robert, As we are all aware the lead-free movement has been somewhat popular lately. We have had in depth discussions about materials, processes and procedures. How about training or re-training? I believe this would be one of the biggest chal

Dr. Lee, We have seen a small decrease in shear strength for Pb/Sn plated components attached with Sn/Ag/Cu solder compared to components with a Pb-free finish. With the jump in the cost of Pd, we are struggling to define a practical Pb-free

Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a melt
