Title: Taekeun Lee: Innovator in Semiconductor Packaging

Introduction

Taekeun Lee is a prominent inventor based in Ichon-si, South Korea. He has made significant contributions to the field of semiconductor packaging, particularly through his innovative designs and manufacturing processes. With a total of 4 patents to his name, Lee continues to push the boundaries of technology in this critical area.

Latest Patents

Among his latest patents is a groundbreaking design for a plastic ball grid array package with an integral heatsink. This invention employs a metal heat spreader with supporting arms embedded in the molding cap. The design ensures that the embedded supporting arms are not directly affixed to the substrate, or if they are, they are affixed using a resilient material such as an elastomeric adhesive. The process for forming this package involves several steps, including placing the heat spreader in a mold cavity and injecting molding material to create the molding cap. This innovative approach enhances manufacturability and reliability in use.

Another notable patent by Lee is a method for manufacturing a plastic ball grid array package with an integral heatsink. This method mirrors the previous patent's design and process, emphasizing the importance of the heat spreader's positioning and the use of elastomeric adhesive to maintain the appropriate alignment during the injection of molding material. The roughened under surface of the heat spreader or the inclusion of a black copper oxide layer further improves adhesion and contact with the molding material.
