Abstract:
A method is provided for coating an optoelectronic chip-on-board module, including a flat substrate populated with one or more optoelectronic components, having a transparent, UV-resistant, and temperature-resistant coating made of one or more silicones. A corresponding optoelectronic chip-on-board module and a system having multiple optoelectronic chip-on-board modules are also provided. The method includes the following steps: a) preheating the substrate to be coated to a first temperature; b) applying on the preheated substrate a dam that encloses a surface area or partial area of the substrate to be coated, the dam being made of a first, heat-curable, highly reactive silicone that cures at the first temperature; c) filling the surface area or partial area of the substrate enclosed by the dam with a liquid second silicone; and d) curing the second silicone.
Abstract:
A circuit board that is to be mounted in a connector socket includes a plurality of electrical connectors located along a side edge of the circuit board. Retention bosses are formed on first and second opposite sides of the circuit board, each of the retention bosses protruding from a surface of the circuit board and extending parallel to and adjacent to the first edge of the circuit board. When the first edge of the circuit board is inserted into a slot of a connector socket, contact surfaces of the first and second retention bosses contact top surfaces of the connector socket to help immobilize the circuit board with respect to the connector socket. Adhesive layers on the contact surfaces of the first and second retention bosses may adhere to the top surfaces of the connector socket to help hold the circuit board immobile with respect to the connector socket.
Abstract:
An electronic control device includes a substrate, a plurality of component-mounted wires, a plurality of electronic components, a common wire, an interrupt wire and a protective layer. The component-mounted wires and the common wire are disposed on the substrate. The electronic components are mounted on the respective component-mounted wires and are coupled with the common wire. The interrupt wire is coupled between one component-mounted wire and the common wire, and is configured to melt in accordance with heat generated by an overcurrent to interrupt a coupling between the component-mounted wire and the common wire. The protective layer covers a surface of the substrate including the interrupt wire and defines an opening portion so that at least a portion of the interrupt wire is exposed.
Abstract:
A semiconductor device has a semiconductor die with die bump pads and substrate with trace lines having integrated bump pads. A solder mask patch is formed interstitially between the die bump pads or integrated bump pads. The solder mask patch contains non-wettable material. Conductive bump material is deposited over the integrated bump pads or die bump pads. The semiconductor die is mounted over the substrate so that the conductive bump material is disposed between the die bump pads and integrated bump pads. The bump material is reflowed without a solder mask around the integrated bump pads to form an interconnect between the semiconductor die and substrate. The solder mask patch confines the conductive bump material within a footprint of the die bump pads or integrated bump pads during reflow. The interconnect can have a non-fusible base and fusible cap.
