Does anyone know of a PCB material that is better at preventing arcing than fr4 or g10?

Yes. Ceramic is much better. We use FR4 in fairly high voltage circuits. What are the particulars? * Where are you arcing * How many layers, prepreg, etc

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?

Nelco was developed by Park [ http://www.parknelco.com/parknelco/highspeed.htm ] Without fairly involved testing, you may be forced to rely on a c of c from your fabricator. Although, Park may be able to give you a lead.
