    Abstract: A method of manufacturing a circuit board having waveguides including forming a waveguiding structure by injection molding. The waveguiding structure includes a plurality of waveguides arranged at intervals and at least one connecting portion connecting two adjacent waveguides. Each waveguide includes a waveguiding substrate and at least one protrusion on the waveguiding substrate. The connecting portion is removed to obtain at least two waveguides. A metal layer is formed to wrap the whole outer surface of each waveguide. A plurality of receiving grooves is formed to penetrate a wiring board. Each waveguide wrapped by the metal layer is embedded in one of the receiving grooves. The waveguides and the wiring board are fixed. A portion of the metal layer on a surface of each protrusion facing away from the waveguiding substrate is removed. A circuit board is also provided.

    Abstract: The present invention relates to a multi-layer substrate which can be used in a wireless signal transmission/reception apparatus, etc, a through-hole and a first waveguide and a second waveguide which are formed by conductive films enclosing the inner surface of the through-hole are formed on an upper substrate and a lower substrate of the multi-layer substrate, respectively, and an RF signal can be transmitted between an upper surface and a lower surface through the two waveguides. A process of manufacturing a multi-layer substrate by a Surface Mount Technology (SMT) is used, so that a waveguide passing through the multi-layer substrate can be precisely and easily formed.
