Latest Patents

Botelho's latest patents include advancements in micro Kelvin probes and methodologies. The micro Kelvin probe assembly he developed determines the resistance or impedance of a device under test (DUT) with two spaced contacts. The assembly utilizes an ammeter to flow current through the DUT and a voltmeter to measure the voltage drop across it. A printed circuit board (PCB) carries two pairs of contacts, with traces leading to each contact. An anisotropic conductive elastomer (ACE) material serves as an electrical interposer, ensuring effective contact with the PCB. The DUT is positioned on the ACE, aligning its contacts with the PCB contacts. This innovative design allows for accurate voltage measurements without interference from the interposer. Additionally, the PCB contacts are arranged in concentric circles, providing a consistent contact surface area that accommodates misalignment.
