Try an intermediate paste like Loctite/Henkle 218. It's design is to be used in a mixed lead/lead-free process.

In addition to the response from Board House... You WILL see delamination at lead-free temp even during reflow.. more often than not.... sometime manufacturer's try to get aways with it by pre-baking the board to remove moisture..but I think one has

It goes to show, EVERYONE (Equipment OEM's, solder paste, flux, wick, etc) is benefitting from this Lead-Free legislation. It's even created jobs in the US, and has taught many a Process Engineer the basics of soldering and profiling.
