Latest Patents
One of Hung-Kun Lee's latest patents is a fabricating method of a flexible circuit board. This method involves several steps, starting with the provision of a metal carrier foil that has a metal oxide layer on its surfaces. The metal oxide layer is formed through the spontaneous oxidization of the metal carrier foil in ambient air, providing passive protection in a sulfuric acid solution or an acidic copper sulfate solution. A conductive seed layer is then electroplated onto the metal oxide layer. Following this, a flexible insulating layer is created on the conductive seed layer through a polyimide casting process. The metal carrier foil is subsequently peeled off from the conductive seed layer, which is supported by the insulating layer. Finally, a patterned circuit is formed on the insulating layer through photoresist coating, developing, and etching.
Another significant patent is related to a carrier-attached copper foil and the method for manufacturing it. This method includes providing a carrier foil made of stainless steel, titanium, aluminum, nickel, or an alloy thereof, which has a surface oxide layer. A copper foil is then formed onto the carrier foil to prepare the carrier-attached copper foil.
