to manage heat created by power components.
PCB * offers several unique features for design engineers.
Components can be soldered directly to the etched copper
Layer of`
conductive dielectric layer. Also, heat generated by power
components is automatically transferred through this layer to
the base plate of'-
resistance of the circuit board is significantly reduced.
