Brief Introduction
This low-loss, high-performance multi-layer PCB is constructed using TUC's TU-883 core and features 20 copper layers. The copper foils alternate between 1 oz and 0.5 oz. The overall thickness of the PCB is 3.0 mm, with immersion gold plating on the pads, a green solder mask, and white silkscreen. The board includes an HDI configuration with blind vias from the top to inner layer 1, from inner layer 18 to the bottom side, and buried vias connecting inner layer 1 to inner layer 18. It is designed as an impedance-controlled PCB, maintaining 50 ohm impedance on each signal layer with a tolerance of 10%. Fabricated according to IPC-class 2 standards, each set of 10 boards is vacuum packed for shipment.
