Title: The Innovative Contributions of Han-Kun Hsieh
Introduction
Han-Kun Hsieh is a notable inventor based in Miaoli, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of advanced circuit board technologies. With a total of 6 patents to his name, Hsieh's work has had a considerable impact on the industry.
Latest Patents
One of Hsieh's latest patents is focused on the formation of electroplate solder on an organic circuit board for flip chip joints and board-to-board solder joints. This method involves providing an organic circuit board with a surface that bears electrical circuitry, including at least one contact pad. A solder mask layer is applied to the board surface, which is then patterned to expose the pad. Following this, a metal seed layer is deposited using various techniques such as physical vapor deposition or electroplating. A resist layer is formed over the metal seed layer, and solder material is created in the opening by electroplating. The resist and the underlying metal seed layer are then removed to complete the process.
Another significant patent by Hsieh is for a padless high-density circuit board and its manufacturing method. This method includes providing a circuit board substrate and forming external wiring with a plurality of external terminals. A solder mask is applied over the substrate and external wiring, with openings exposing the external terminals. Conductive bumps are then formed on the exposed terminals for connection with external devices in subsequent assembly processes.
