Another measurement tool is a refractometer to measure light refraction. The saponifier will have a specific refraction property is measure agianst an index.

I am working with a BGA package. The laminate layer is being modeled as BT-Cu smear. The thermal conductivity of BT is 0.19 W/mK. Does anyone know what the density and specific heat values are for BT?

Mitsubishi Gas & Chemical's Bismaleimide-Triazine (BT) resin laminates are the defacto standard material for BGA. Have you checked with them?

Depends on the manufacturer but I know with Kester they strictly tell you once paste dries out it can never be brought back to usefulness. Adding flux will alter the properties of the paste and may affect the final product.

How do you define torque setting for screw?What does 1)Screw with Bolt size 3-48 means ? 2)Thread Size M3 means? 3)Fasterner Property Class?

Whether or not conformal coating creates a reliability problem if it bridges the gap between the board and bottom of the part depends on the properties of the coating. A low modulus coating is fine, but one thats modulus increases at colder temperat

Rather than cleaning a water soluble flux residue off the board, by encapsulating the product. covering the board or the component with lets say a Hysol encasulant. Would this prevent the active flux residue from migrating and deteriorating the elect
