Latest Patents

One of I-Chung Tung's latest patents is titled "Formation of electroplate solder on an organic circuit board for flip chip joints and board to board solder joints." This patent discloses a method for fabricating electroplate solder on an organic circuit board, which is essential for forming flip chip joints and board-to-board solder joints. The process begins with an organic circuit board that has a surface bearing electrical circuitry, including at least one contact pad. A solder mask layer is applied to the board surface and 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 then formed over the metal seed layer, and solder material is created in the opening by electroplating. Finally, the resist and the underlying metal seed layer are removed.

Another significant patent is the "Method for making a multilayer circuit board having embedded passive components." This invention outlines a process for fabricating a core circuit board that includes passive components like resistors, capacitors, and inductors. The method involves forming a resistive film on one side of a conductive foil, which is then laminated onto a high dielectric layer. The electrodes for various passive components and electrical circuit patterns are created simultaneously on the conductive foils. This innovative approach allows for the construction of multilayer circuit boards with embedded passive components.
