Title: Joseph S. Antao: Semiconductor Packaging and Lead-Conditioning Innovations.

Introduction

Joseph S. Antao is an inventor based in Allen, Texas, whose patent work addresses semiconductor manufacturing and package assembly. His inventions include methods for forming ball grid array contacts and equipment for conditioning leads on quad semiconductor packages. He is associated with Texas Instruments Corporation and holds 2 patents.

Latest Patents

Antao’s patent, “Method of Forming Ball Grid Array Contacts,” describes a process for creating solder balls on a semiconductor package. A solder sheet with projecting solder elements is aligned over the package’s contact areas and heated. The solder elements separate and reflow, with surface tension shaping each into a solder ball positioned over a contact area. The method provides a way to form electrical contacts for ball grid array devices.

His patent, “Lead Conditioner for Quad Semiconductor Packages,” describes a system that conditions semiconductor-device leads to meet specified alignment and positioning requirements. The system includes stations for adjusting lead offset, planarity, and tweeze, as well as a centering station, transport assembly, input and output stations, and electronic controls. Its offset conditioner shifts leads and returns them to a centered position, while the planarity conditioner reshapes and repositions lead tips to bring them into a substantially coplanar arrangement. The design also features a self-centering device and durable laminated-steel blades.

Career Highlights

Antao’s patents focus on practical manufacturing challenges in semiconductor packaging. One invention supports the formation of solder contacts, while the other addresses the precise conditioning of package leads. Together, they reflect work aimed at improving the consistency and accuracy of semiconductor assembly processes.
