Traditionally, the way to improve thermal conductivity in electronic devices relied on either paste or very expensive special thermal elastomers.
In the last 2 years GSI’s flexible graphite foil, with a heat transfer co-efficient higher than copper or aluminium, has proven itself, especially with LED lights. Apart from the exceptional thermal conductivity there is no mess and of course there is a significant price advantage too.
Die-cut self-adhesive shapes mean that you can apply exactly the same amount, the same way, every time. No training or expensive machinery is required plus you will be able to accurately control your stock. Muuuch better.
