Abstract
Disclosed herein is a printed circuit board for an optical waveguide, including: a substrate; an insulation layer having a through hole and formed on the substrate; a lower clad layer formed on a bottom of the through hole; core part formed on the lower clad layer; and an upper clad layer formed on the lower clad layer and the core part and thus covering an exposed surface of the core part.
Claims16
A printed circuit board for an optical waveguide, comprising:
- a substrate;
- an insulation layer having a through hole and formed on the substrate;
- a lower clad layer formed on a bottom of the through hole;
- a core part formed on the lower clad layer;
- and
- an upper clad layer formed on the lower clad layer and the core part and thus covering an exposed surface of the core part.
A method of manufacturing a printed circuit board for an optical waveguide, comprising:
- forming an insulation layer having a through hole on a substrate;
- forming a lower clad layer on a bottom of the through hole;
- forming a core part on the lower clad layer;
- and
- forming an upper clad layer covering the core part on the lower clad layer and the core part.
A method of manufacturing a printed circuit board for an optical waveguide, comprising:
- forming a lower insulation layer having a lower through hole on a substrate;
- forming a lower clad layer in the lower through hole;
- forming an upper insulation layer having an upper through hole connected with the lower through hole to thus form a single through hole on the lower insulation layer;
- forming core part on the lower clad layer;
- and
- forming an upper clad layer covering the core part on the lower clad layer and the core part.
