Where does the 260 Deg. C spec. come from that you mention?

Hi everyone! I am looking for a lead-free solder that will survive a customer reflow of 260C. I am currently using SN10/Pb88/Ag02 but the reflow temperature is to high (320C) for the FR4 boards that we have. I know there are higher temp FR4 boards

Can anyone tell me if there is a volume difference between a pound of lead vs. lead free solder? Does lead free solder attack stainless or castiron when it's not molten? Thanks. Jay

I am curious whether anyone is experiencing AOI issues in transitioning to lead-free solder inspection.

We've never used the 99*C lead-free solder you mention. We have used a leaded solder that can form a 93*C eutectic solder. So, we had to be sure the service temperature [of the solder connections] as below 80*C.

How effective will current wave solder equipment and processes be with lead free solder? What temperatures will be required? How will dross generation compare?

I need solder that has a solidus temp. of approximately 260C so that when sent through a second reflow of 260C the solder doesn�t become liquidus. However, I need the max reflow to be less that 300C because of the substrate.

try Indium Corp's SMQ230. http://ncsmq230.indium.net/ Peak "on board" temps of 229C with good wetting have been obtained.

You ned to speak with an apps engineer from a paste supplier that can go through their alloys. I know Indium has such alloys. Any vendor should be able to supply you a list of alloys avbl in NC paste with their liquidous points.
