FR406 is manufactured by Isola, they have an FR4
(IS410)with a higher Td (350C). That would be a better
choice for the lead-free process. I always try to recommend
that that fab drawing notes callout the characteristics of
the material required, rather than specify a particular
supplier's product. In this case indicate the Td
requirement and allow the PCB fabricator to use his
existing supplier's product that meets the Td requirement.

Thank you,

Hi TechNetters

Can I use FR406 175 Degrees C laminate during a lead free
assembly process
where the reflow temp will be around 260 Degrees C. ?
The boards will be ENIG.  Any disadvantages.

I know there was a thread, but I can't find it.
