Comparative Study of Phosphorus-based Flame Retardants in Halogen-Free Laminates

This paper compares performance of two phosphorus-based flame retardants: poly-(m-phenylene methyl phosphonate) (PPMP) recently introduced to the market and 9,10-dihydro-9-oxa-10-phosphenanthre .. read more

Dielectric Constant and Dissapation Factor of Fr4 Laminates Produced Using Specific Vendors of Fiberglass Yarn

Currently there is not a specification within the IPC for the DK and DF of E-Glass reinforcements and there is no requirement to report the DK and DF of the glass formulation used to produce E- .. read more

Novel Polyimide Build-up Material for Fine-line Fabrication

We have developed a new thermosetting polyimide build-up material for high performance build-up PWBs,which can mount high speed CPUs with high I/O numbers. These PWBs meet the following require .. read more
