Title: Innovator Spotlight: John Briar

Introduction

John Briar, an esteemed inventor based in Phoenix, Arizona, has made significant contributions to the field of electronic engineering. With a total of three patents to his name, Briar has demonstrated his innovative prowess in developing advanced technologies that enhance the functionality and efficiency of circuit boards.

Latest Patents

Among his latest patents, Briar has developed a groundbreaking invention titled "Grid array assembly of circuit boards with singulation grooves." This invention introduces a grid array assembly that utilizes a thin copper or steel carrier frame featuring apertures extending longitudinally. A series of semi-flexible substrate printed circuit boards are mounted to the peripheral edges of these apertures, which include bonding pads and metallization on one surface, as well as conductive vias that extend to a contact pad array on the opposite surface. The carriers, along with the attached circuit boards, undergo a systematic process where an IC die is mounted, wire bonds are established, and the assembly is encapsulated using part of the carrier strip as a mold gate, facilitating the formation of a package body. Following this, the grid array assemblies are singulated from the carrier strip.

Additionally, Briar holds a patent for a "Method of making grid array assembly," which incorporates a series of steps using semi-flexible substrate printed circuit boards. This method involves testing conforming boards, selecting accepted ones, and subsequently mounting them onto a carrier strip. After going through the process of IC die mounting and encapsulation, interconnecting balls or bumps are placed on the contact pads before the assembly is removed from the strip.
