Summary of Expertise: Listed with other top experts in: 
ELECTRIC CONTACT; ELECTRICAL CONNECTOR DESIGN. Expert has extensive experience studying metals and metal surfaces related to electrical conduction processes and how they occur in bulk and across interfaces. Such an understanding is a critical first step in the design of electronic connectors. He is familiar with the key surface characteristics for both conduction and wear processes. Expert's metallurgical background is the basis of his knowledge of materials and processes related to electrical and electronic connectors. He is experienced with dry, switch, and wiping contacts. He can answer questions on aluminum, copper, nickel, and silver connector materials as well as solderability and conductor jointing.

ELECTRICAL CONNECTOR RELIABILITY. Experienced with material selection and the design of electrical connectors, Expert has authored several papers on contact finishes and permanent connection technologies. He has contributed to the development of test procedures to assess connector performance and reliability. He also developed and marketed a microcoax connector for medical ultrasound equipment.

CONTACT RESISTANCE. Expert has extensive experience in studying the materials basis of contact physics, which includes both electrical contact resistance and the wear behavior of contact interfaces. He has published papers on relating contact resistance changes to connector qualification/performance and evaluation of connector reliability.

CRIMPED CONNECTOR, CRIMPING. Expert published articles on crimped connection processes and related technology, including a "Best in Conference Award" from the IICIT in 1997 for a paper titled "A Closer Look at Crimped Connections." He also contributed to development of a model of crimping processes while at AMP Incorporated.

ELECTRICAL CONTACT FINISH. A significant portion of Expert's work has involved electrical contact finishes. He published articles on contact finish selection criteria in assorted industry journals as well as articles on corrosion processes in noble metal finishes in mixed flowing gas environments.

INSULATION DISPLACEMENT CONNECTOR. Expert is familiar with insulation displacement connectors (IDCs), having published an article on IDC technology in an industry journal. He had contributed to the development of IDC terminal design criteria while at AMP Incorporated.

WIPING CONTACT. In his work with electrical contacts, Expert has gained particular expertise with wiping contacts. His knowledge of this area has led to the publication of three papers on wiping action as a function of connector design, relating to parameters of contact force and geometry.
