Warpage problem causes * MLB constructions (not homogeneous or unbalanced - too resin rich or poor) * Supplier process capabilities (lamination cycles) * Material selections (usually cheap and dirty), etc.

Are there significant diffrences in terms of soldering (wire for manual solder) performance by using RO vs RE fluxes? Wich are the main differences between the two fluxes? Thank you Regards.....GSx

At the end of the day, you won't notice a difference, while soldering, but if you clean the flux residues.

Your warpage problem could be caused by change in: * Multilayer board construction (not homogeneous or unbalanced - too resin rich or poor) * Supplier process capabilities (lamination cycles) * Material selections (usually cheap and dirty), etc.
