Abstract
A multilayer printed circuit board includes an inner circuit layer, a first outer circuit layer, a second outer circuit layer, a via, and a layer of high dielectric dissipation solder resist ink. The first outer circuit layer includes a first trace for transmitting a high frequency signal. The inner circuit layer includes a second trace, and is formed between the first outer circuit layer and the second outer circuit layer. The via is formed from the first outer circuit layer to the second outer circuit layer, and is coupled to the first trace and the second trace. The second trace is coupled to the first trace through the via for transmitting the high frequency signal. The layer of high dielectric dissipation solder resist ink is formed on a terminal of the open stub of the via exposed outside of the second outer circuit layer.
