Graphite interface
The TH-3000 range of products are materials that are made up of very
high density natural graphite. They are thermal and electrical conductors
along the 3 axes (x-y-z). They are perfectly suited for use as an
economical alternative to copper.
Examples of applications:
Advantages:
Options:
- Memory
- Micro BGA
- Power semiconductor
- Heat spreader
- Electrical and thermal
conductor
- Weight gain
- Cutting to required dimensions
