Hi I'm Dhoy a IMDS analyst, I have difficulty with my Chinese PCB supplier in getting correct material composition of solder mask or solder resist in Printed Curcuit Boards. My supplier keeps sending me material composition of solder mask with solvents in it. IMDS requires that material reporting is only for the final product. Which means the solder mask must be dried and solvents must had dried or evaporated because there is no liquid part that remains on the final pcb:frust: .

If there is a chance to get to their mask supplier, they may be knowledgeable enough to give you that data. I do not envy your predicament...
