Title: The Innovative Contributions of David Van Heerden

Introduction

David Van Heerden is a notable inventor based in Baltimore, MD (US). He has made significant contributions to the field of electronics through his innovative patents. With a total of 9 patents, Van Heerden has developed methods and materials that enhance the performance and reliability of electronic components.

Latest Patents

One of his latest patents is a method for low-temperature bonding of electronic components. This method allows for the bonding of an LED assembly or other electronic packages to a substrate PCB containing a heat sink. By utilizing layers of reactive multilayer foil disposed between the contacts of the electronic package and the associated contact pads on the supporting substrate PCB, this method initiates an exothermic reaction. The generated heat, combined with applied pressure, melts adjacent bonding material to create strong electrically and thermally conductive bonds without damaging the electronic package or heat-sensitive components.

Another significant patent involves reactive composite material structures with electrostatic discharge protection. Van Heerden discovered that electrostatic discharge (ESD) could ignite unprotected reactive composite materials. He developed a method to protect these materials from ESD ignition by applying conducting and insulating materials at strategic locations. This innovation allows for the design of ESD-protected reactive composite material structures suitable for sensitive applications, such as ignition of propellants and controlled self-destruction in equipment.
