Depends upon the alloy and the environment, Werner. I have heard that some
seem to do well at only 20-25 degrees higher, and even better if they are
used in a nitrogen-rich atmosphere (the fillets turn out somewhat shinier,
too). But, the reflow temperatures will indeed be higher with Pb-free
solders. No doubt about it!

Hi Ramon,
You are too optimistic--"Not to mention the extra stress that is going to be

placed on the components as the reflow profiles have to be 20 degrees higher

than they are

now"--try mmore like 30 to 35°C.
