The cheaper material will degrade quickly under rework pressure,
especially any type of BGA, or socket.

Subject: [LF] Cost pressures starting!

We have successfullly made the transtition, and are beginning to produce
complaint products.

And that's starting to drive the bean counters into a frenzy.  Our new
PCB
material spec is calling for 330Td, non-dicy, Z-Axis max, etc... and
guess
what, - it costs more than the old 140Tg material.  Now they want to go
back to the old material - throw out a year of research and testing -
because they ran a few boards using the old material.

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

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