Latest Patents

Dickinson’s listed patents, both titled “Heated Circuit Assembly Tester and Method,” describe approaches to applying controlled mechanical stress to circuit boards and their mounted components while the boards are heated.

One patent describes an insulated enclosure that heats circuit-board assemblies at a regulated temperature. A fixture holds each assembly while a motor applies angular displacement at a predetermined amplitude, stressing solder joints between the board substrate and its components. The controlled process is designed to be repeatable across tests and batches.

The other patent describes a testing apparatus and method that twist a heated circuit board to create shear stress at component joints, simulating stresses associated with thermal cycling. The apparatus can be computer-controlled to regulate the twist angle during repeated cycles. Electrical resistance monitoring can help identify when and where a joint fails, with the results recorded by cycle count and failure location.

Career Highlights

Dickinson’s documented patent contributions focus on reliability testing for electronic assemblies. His inventions combine heat, controlled twisting, and measurement to help evaluate the durability of solder joints and mounted components.
