Title: **Won-Cheol Bae: Innovator in Component-Embedded Printed Circuit Board Technology**

Introduction

Won-Cheol Bae, based in Kyunggi-do, South Korea, is a notable inventor known for his contributions to the field of printed circuit board (PCB) manufacturing. With a remarkable record of 6 patents to his name, he has made significant strides in developing methods for advanced PCB technology. His innovative approach has enhanced the precision and efficiency of manufacturing processes within the electronics industry.

Latest Patents

Among his latest patents is a groundbreaking method of manufacturing a component-embedded printed circuit board. This technique involves several steps: first, mounting a component on a first copper foil with an established pattern, ensuring electrical connectivity. Next, an insulation layer with a cavity is stacked on a second copper foil featuring conductive protrusions. By combining the first and second copper foils, the component is encapsulated within the cavity, achieving electrical connections via the conductive protrusions. The subsequent removal of specific areas of both foils creates circuit patterns, allowing for the production of a thin printed circuit board suitable for embedding flip-chip components.

Another notable patent is related to the manufacturing of component-embedded PCBs through a meticulous method. This process involves perforating a cavity within a core substrate and inserting a component therein. Following this, a film layer is stacked on the core substrate, where posts are selectively left behind in line with the component's electrodes. An insulation layer is then applied, allowing the posts to penetrate, ensuring they are exposed at the surface. By removing the posts, via holes are created, minimizing damage to the components and reducing tolerance defects and residues. This approach enhances precision and allows for a finer pitch in PCB design.
