/94
DE156 is a base material of type FR-4 meeting the /94 requirements for halogen free.
The resin matrix is based on a modified epoxy resin; conventional E-glass-fabric is used for reinforcement. The requirements of flammability class V-0 as per UL slash sheet 94 are met without addition of antimony compounds.
Since this grade does not contain halogens, it displays greater thermal stability than a standard FR-4, as T-260 measurements prove (Time to Delamination).
