There has been a increase in the number of requests for reflow profiles for lead-free solders. This is a change from last year, where a majority of the requests had been for a low voiding reflow profile. Now, customers are just asking for reflow profiles, in general. Also, a majority of the question for these reflow profiles are coming from companies that are considered RoHS exempt. This trend over the past 2 months tells me that these customers, RoHS exempt companies for tele-communications, medical and military contractors, are now starting to look into lead-free solders.
There is one more surprising thing. Not all of the lead-free solders are the usual Tin / Silver / Copper (Sn/Ag/Cu or SAC). There are many requests for a low temperature lead-free solder, as well.
