Bonded Fin Heat Sink
A bonded fin heat sink are normally used is forced air circulation environment as there is no limitation on fin height to fin space ratio. SNS cooling technology offer bonded fin products with ratio as high as 40:1. SNS uses following methods to bond the fin & base
- Low temperature soldering material (ROHS compliant)
- Aluminum filled high Thermally Conductive Epoxy (ROHS compliant) as per following temperature rating.
- low temperature resistance epoxy-max working temperature of 275 °F
- High temperature resistance epoxy-max 400 °F
SNS cooling technology offers various combination of base & fin material per details below.
| Base Material | Fin Material | Method of Joining |
|---|---|---|
| Al Alloy 6061-T651 OR Al Alloy 6063-T5 |
Copper Fin C11000 Al Grade 1100,3003, 3005, 5005, 5052,6061, 7075 |
ROHS Thermally Conductive epoxy OR ROHS Silver Solder |
