Abstract: A method for backside metallization includes inkjet printing a pattern of nanosilver conductive ink on a first surface of a silicon wafer. The silicon wafer includes a plurality of dies. The pattern includes a clearance area along a scribe line between the dies. A laser is focused, through a second surface of the wafer, at a point between the first surface of the silicon wafer and the second surface of the silicon wafer. The second surface is opposite the first surface. The dies are separated along the scribe line.

Abstract: A catheter has a distal assembly with at least one loop with ring electrodes. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and a U-shape bend therebetween. The U-shape bend is anchored at a distal end of a deflectable section which is reinforced by at least one washer having at least two holes, each hole axially aligned with a respective lumen in the deflectable section. Each hole is centered with a lumen so that each puller wire portion therethrough is straight and subjected to tensile force only. A proximal end of the support member is flattened and serrated to provide a better bonding to the distal end of the deflectable section.

Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives a set of queries for data from a dataset stored in a first database instance. The program further determines that a value calculated based on a set of metrics associated with processing the set of queries for data from the dataset stored in the first database instance exceeds a threshold value. In response to the determination, the program also replicates the dataset from the first database instance to a second database instance.

Abstract: In a method and apparatus, an electrical load is disposed across an electric power source. First and second electrical components are disposed between first and second terminals, respectively, and the load and power source. An open circuit is defined between the first and second terminals in absence of a test meter. The first electrical component is configured so that the first component passes at most a low level electric current to the first terminal upon a short circuit condition. The second electrical component is configured so that the second component passes at most a low level electric current to the second terminal upon a short circuit condition.

Abstract: A microelectronic device has a pillar connected to an external terminal by an intermetallic joint. Either the pillar or the external terminal, or both, include copper in direct contact with the intermetallic joint. The intermetallic joint includes at least 90 weight percent of at least one copper-tin intermetallic compound. The intermetallic joint is free of voids having a combined volume greater than 10 percent of a volume of the intermetallic joint; and free of a void having a volume greater than 5 percent of the volume of the intermetallic joint. The microelectronic device may be formed using solder which includes at least 93 weight percent tin, 0.5 weight percent to 5.0 weight percent silver, and 0.4 weight percent to 1.0 weight percent copper, to form a solder joint between the pillar and the external terminal, followed by thermal aging to convert the solder joint to the intermetallic joint.
