Title: Innovations by Inventor Albert Yeh
Introduction
Albert Yeh is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of printed circuit board (PCB) technology. With a total of 2 patents, his work focuses on optimizing manufacturing processes for PCBs.
Latest Patents
Albert Yeh's latest patents include a method for optimized filling holes and manufacturing fine lines on printed circuit boards. This innovative method separates the processes of filling holes and creating fine lines. The inner wall of the hole is metalized with reduced graphene oxide (rGO) and then electroplated to fill the hole with copper. This approach allows for independent consideration of operating parameters, resulting in evenly compact copper-plating fillings and fine lines with square profiles. Another significant patent is a method for manufacturing traces of PCBs, which utilizes a periodic pulse reverse (PPR) pattern plating process. In this method, the walls and bottoms of drilled holes are modified with rGO, enabling the formation of vias filled with copper and a very thin copper layer on the substrate. The process culminates in the creation of fine traces with widths and spaces less than 30/30 µm, meeting the requirements of high-density interconnection (HDI) technology.
