Abstract

A rigid-flexible optical and electrical printed circuit board (RFOE-PCB) was fabricated using a conventional PCB manufacturing process for mobile devices. The RFOE-PCB was designed to be embedded with a flexible 45-ended optical waveguide. In order to apply it to mobile devices, a repeating folding test and an environment test were carried out for physical and optical reliability. The RFOE-PCB successfully passed the reliability tests.
