• thermal-bond 5.0F: Thermally Conductive Resin Coated Film Bondply

    UL Approval: E214381 30/04/2024

    Resin Coated Film (RCF) Bondply is an unreinforced adhesive system coated onto PET film for use in high performance and high reliability multilayer PCB stack-ups.

    VT-4B7H is a high Tg, ceramic-filled, thermally conductive (7.0 W/mK), halogen-free thermoset resin system, specifically designed for use in multilayer PCBs requiring enhanced levels of heat management and thermal conductivity. Thermal-bond RCF can be combined with other Ventec laminate & prepreg systems including tec-thermal IMS, VT-5A2 and VT-4A2H thermally conductive laminates & prepregs in hybrid stackups.
