A noble metal-coated silver bonding wire suppresses corrosion at the bonding interface even under severe conditions of high temperature and high humidity in automobiles and does not cause energization failure in a semiconductor device in which electrodes of a semiconductor chip and electrodes of lead frames or the like are connected by the bonding wire. The noble metal-coated silver wire for ball bonding wire includes a noble metal coating layer on a core material made of pure silver or a silver alloy, wherein the wire contains at least one sulfur group element, the noble metal coating layer includes at least one palladium layer, the total palladium content relative to the entire wire is 0.01 mass % or more and 5.0 mass % or less, and the total sulfur group element content relative to the entire wire is 0.1 mass ppm or more and 100 mass ppm or less.

The present disclosure is directed to a leadframe package with a surface mounted semiconductor die coupled to leads of the leadframe package through wire bonding. The leads are partially exposed outside the package and configured to couple to another structure, like a printed circuit board (PCB). The exposed portions, namely outer segments, of the leads include a plating or coating layer of a material that enhances the solder wettability of the leads to the PCB through solder bonding. The enclosed portions, namely inner segments, of the leads do not include the plating layer of the outer segment and, thus, include a different surface material or surface finish.

Embodiments relate to using a pickup assembly to place light emitting diodes (LEDs) onto an electronic display substrate after fabrication of the LEDs. An LED assembly system places LEDs on a temporary substrate after fabrication. Pickup heads of the pickup assembly are coated with a conformable material to enable attachment of each LED to a pickup head. The pickup head removes the LEDs away from the temporary substrate and aligns the LEDs onto a target substrate. The LED assembly system provides heat to an electrode of the LEDs and a corresponding electrical contact pad of the target substrate. The pickup assembly applies force to the LED on the target substrate, such that with the heat, the electrode of the LED and the electrical contact pad are bonded. The pickup assembly releases the LED onto the target substrate.
