As stated in the title I would like to know the thermo-elastic material properties, most preferably the E-modulus and CTE in x- and y-direction, for Epoxy/E-glass laminates and/or prepregs for various fibreglass cloth styles.
Datasheets only give rough average estimates, usually for 50% resin count. For the CTE this would be (for Nelco N4000 6FC) be 12-15 ppm/K in x and y. However, the difference between a thin 2 mil laminate with high resin content and 106 Glassfibre cloth this value skyrockets to ~30 ppm/K. For really thick 62 mil laminate with 7xxx glass fibre cloths with low resin content, the CTE drops to around 10,5 ppm/K.
I'm looking for some documentation that has these thermo-elastic values for specific fibreglass cloths (pref. 106, 1080, 2113, 2114, 7628), lam/pp thicknesses, resin or fiber volume content. The type of manufacture does not matter much. A bonus would also be information about C-stage prepregs.
I need this information to calculate PCB warpage by using the classical laminate theory.
Could anyone help me with finding this information?
