MHT is an advanced Grade 3 (HTE) copper foil with a high temperature,
heat resistant treatment designed to provide high bond strength on a wide range of high Tg substrates and low loss resins.
Typical substrates include polyimide, BT, CE, and hydrocarbon-ceramics. Performance benefits include:
- •Excellent thermal stability for improved PWB performance.
- •Enhanced bonding treatment for Polyimide and other high Tg resins results in improved adhesion.
- •Low profile for foil thicknesses less than 70 microns for finer lines and consistent etching.
