Thanks for the links I didn't know about these services. They use TG-130 or TG-140 which are lower temperature (130C/140C) FR4 board ratings. The surface may melt when de-soldering at high temperature. I usually prefer TG-170/TG-180 boards as I find them to be more reliable during rework. But can't argue with those prices. :)
