FR4 Thermal properties to consider when designing PCBs

October 1, 2021 9:21 am Published by webmaster Leave your thoughts

When designing PCBs, designers need to consider four very important thermal properties of the FR4 they have chosen to incorporate. In this article, we discuss these crucial properties and explain how Aismalibar's thermal FR4 responds to them.

BOND SHEET CURED + AIR GAP FILLER

Ultra-thin dielectric layer, high dielectric strength,
high thermal conductivity and low thermal resistance.
