Lead-free Compatible… High Speed, Low Loss Multi-layer Materials
MEGTRON 4/4S is designed for Low Dk and High Tg applications, specifically for network equipment, server, routers and measuring instruments. The main attributes of MEGTRON 4/4S are: low dielectric constant and dielectric dissipation factor (Dk = 3.8 and Df = .005 @ 1GHz), Lead-Free soldering RoHS compliant, and High Heat Resistance.
MEGTRON 4S is an improved version of MEGTRON 4 with higher Tg, suitable for multi-lamination cycles and hybrid builds. MEGTRON 4/4S meets IPC specification 4101 /91 /102.
