Home / Application / PCB / Heatsink bonding
For heat sink bonding and power modules the conductive adhesives of the Vitralit® and Elecolit® ranges are ideal.
Properties of the adhesives:
- Adhesives with heat-conducting fillers
- High mechanical strength
- Good thermal stability and low thermal expansion
- Single- and two-component products
- Cures at room temperature with heat, UVA radiation or activator
