PRINTED CIRCUIT BOARD FOR INTEGRATED LED DRIVER
A multi-layer metal core printed circuit board (MCPCB) has mounted on it at least one or more heat-generating LEDs and one or more devices configured to provide current to the one or more LEDs. The one or more devices may include a device that carries a steep slope voltage waveform. Since there is typically a very thin dielectric between the patterned copper layer and the metal substrate, the steep slope voltage waveform may produce a current in the metal substrate due to AC coupling via parasitic capacitance. This AC-coupled current may produce electromagnetic interference (EMI). To reduce the EMI, a local shielding area may be formed between the metal substrate and the device carrying the steep slope voltage waveform. The local shielding area may be conductive and may be electrically connected, to a DC voltage node adjacent to the one or more devices.
Conductive fabric and its preparation and applications
The present invention provides a conductive fabric comprising base cloth and a conductive metallic circuit structure formed on the surface of the base cloth.

The metallic seed layer is an evaporation-deposition layer or a sputter-deposition layer and has a circuit pattern. The chemical-plating layer is applied over the surface of the metallic seed layer. The conductive fabric has improved conductivity and heat generation efficiency.
