Hello all

We are looking about the differences in lead free wave soldering in regard
to different wave systems.
Do somebody know of any experiments regarding different ppm levels if closed
(tunnel system) and open N- systems are compared?
Are ther any differences in Solder Quality in regard to differnt O- levels
in N?

Thanks for your answers

Siggi
