We use materials such as G10, durapol, or FR4. We put a lot of holes in the fixtures so that only enough material is left to support the board during reflow to prevent sag/ warp or whatever. We also try and keep all bot side material in unpopulated

rush316 First, no one stated that PBB and/or PCBE are in FR4. FR4 contain tetra-bromo-bisphenol A [TBBA]. Second, there are classes [and grades] of dielectric materials used in fabricating printed circuit boards. Grades, NEMA LI-1. From these gr
