14 layers thick copper coil board is a multi-layer printed circuit board designed specifically for high-power and high-frequency applications, suitable for power conversion, new energy vehicles, industrial control and other fields.
The 14 layers thick copper coil plate has the following key parameters and process characteristics:
Layers and Copper Thickness: A total of 14 layers, with inner and outer copper thicknesses up to 4OZ (approximately 140 μ m), supporting high current transmission and effectively reducing temperature rise
Complete board thickness: The maximum board thickness is 3.5mm, suitable for high-density wiring and complex structural design.
Blind hole structure: Using blind hole connections between layers 1-7 and 8-14 to improve signal integrity and space utilization.
Can achieve back drilling (Stab <= 2mil), reducing high-speed signal crosstalk
Support mixed compression of RO4003C+HTG materials, balancing high-frequency performance and high temperature resistance.
If you are evaluating the technical compatibility of different suppliers, this type of board performs well in thermal management, conductivity efficiency, and structural stability, especially suitable for power module applications in energy equipment. The board also has good compatibility in the selection of mixed pressure materials and integration with processes.
