Thermal Clad
Bergquist shortens the design cycle and speeds up your time to market.
Thermal Clad substrates offer more flexibility in selecting LED components
Bergquist offers a family of standard thermally conductive insulated
Now you can get a jump-start on your design with one of these star
metal substrate (IMS) circuit boards specifically for LED applications
or square substrates; available in single, strip or array configurations.
which replace conventional FR-4 PCBs. Better thermal management
Choose from 10 different LED footprints to give you the freedom
allows more forward current to be applied to the LED, while still
to select the LED component’s color, brightness and power that best
maintaining desired die temperatures, which means more light and
fits your needs. Optimize the prototyping process with the lowest
possibly reducing the number of LEDs required to achieve the desired
possible operating temperatures and the brightest light output for
