Hi C-Pt-Pete, Werner, John, , , , , IPC LF Listservers,

Well Pete you really hit a nerve, which is really good.
Thanks for starting this fire side chat.

<The questions are - is anyone running lead free solder processes using the
old standard 140Tg, in any kind of volume, with any measurable quality?>

Werner already answered. Thin stuff, small copper weights, with non
complex, heat needing components. We have had notes about this stuff years
ago.

<How do you convince them that RoHS just costs more, but it will get cheaper
eventually?>

I like CA-JoeFj when he said "no" ; yet as time goes on it will get cheaper
than it is right now, as technology introduction pays back it's investment,
increased costs, and your yield is improved. If the laminate market stays
segregated with large volumes towards lower Tg, Tds, than NO you can never
get your costs back down.

Yours in Engineering, Dave
