Diamond-like carbon coating for passive and active electronics

Systems and methods for building passive and active electronics with diamond-like carbon (DLC) coatings are provided herein. DLC may be layered upon substrates to form various components of electronic devices. Passive components such as resistors, capacitors, and inductors may be built using DLC as a dielectric or as an insulating layer. Active components such as diodes and transistors may be built with the DLC acting substantially like a semiconductor. The amount of sp 2 and sp 3 bonded carbon atoms may be varied to modify the properties of the DLC for various electronic components.

Lap shear bonding fixture

A fixture for lap shear bonding a bottom panel to a top panel comprises a bottom tool, a first spacer, a second spacer, and a top tool. The bottom tool has a quadrilateral shape including a top surface, a bottom surface, and four side surfaces and is configured to retain the bottom panel on the top surface. The first spacer is attached to the top surface of the bottom tool adjacent to one edge. The second spacer is attached to the top surface of the bottom tool adjacent to an opposing edge. The top tool has a quadrilateral shape including a top surface, a bottom surface, and four side surfaces and is configured to retain the top panel on the bottom surface. The top tool is further configured to attach to the first spacer and the second spacer such that the top panel contacts the bottom panel.

Additively manufacturing fluorine-containing polymers

A system and method of additively manufacturing a part including electrically conductive or static dissipating fluorine-containing polymers. The method includes depositing fluorine-containing polymer additive manufacturing material onto a build platform, selectively cross-linking portions of the deposited additive manufacturing material, and curing the selectively cross-linked portions such that the part is at least one of electrically conductive and static dissipating.

Multi-layered diamond-like carbon coating for electronic components

A multi-layer coating on an outer surface of a substrate includes a first layer applied directly to the outer surface of the substrate. The first layer includes diamond-like carbon (DLC) configured to mitigate metal whisker formation. A second layer is applied on a top surface of the first layer. The second layer is a conformal coating that includes a second material configured to bind to the top surface of the first layer and fill any microfractures that may form in the first layer. Optionally, a third layer is applied on a top surface of the second layer and includes DLC configured to protect the second layer from oxidation and degradation.
