Embodiments of a thermal compression bonding (TCB) process cooling manifold, a TCB process system, and a method for TCB using the cooling manifold are disclosed. In some embodiments, the cooling manifold comprises a pre-mixing chamber that is separated from a mixing chamber by a baffle. The baffle may comprise at least one concentric pattern formed through the baffle such that the primary cooling fluid in the pre-mixing chamber is substantially evenly distributed to the mixing chamber. The pre-mixing chamber may be coupled to a source of primary cooling fluid. The mixing chamber may have an input configured to accept the primary cooling fluid and an output to output the primary cooling fluid.

A semiconductor chip is mounted on a mounting substrate. The semiconductor chip includes plural first bumps on a surface facing the mounting substrate. The plural first bumps each have a shape elongated in a first direction in plan view and are arranged in a second direction perpendicular to the first direction. The mounting substrate includes, on a surface on which the semiconductor chip is mounted, at least one first land connected to the plural first bumps. At least two first bumps of the plural first bumps are connected to each first land. The difference between the dimension of the first land in the second direction and the distance between the outer edges of two first bumps at respective ends of the arranged first bumps connected to the first land is 20 μm or less.

Provided is an electronic component including a pad region including a plurality of pads extending along corresponding extension lines and arranged in a first direction, and a signal wire configured to receive a driving signal from the pad region, wherein the plurality of pads include a plurality of first pads arranged continuously and a plurality of second pads arranged continuously, and extension lines of the plurality of first pads substantially converge into a first point and extension lines of the plurality of second pads substantially converge into a second point different from the first point.

The present invention is directed to flux compositions and uses thereof. One composition comprises an activator and a solvent being a glycerol ethoxylate with a molecular weight of 200-500. Another composition comprises an activator, a solvent being a glycerol ethoxylate with a molecular weight of 200-500 and an amine. A soldering method for joining objects is also provided, comprising the steps of applying a flux composition to at least a portion of one or more of the objects, and joining the objects.

Disclosed is a printed circuit board having at least one power semiconductor soldered thereon and, as a thermal fuse, a spring having two contact arms fastened to solder pads of the printed circuit board by soldered connections. The spring is under mechanical stress such that at least one of the two contact arms moves away from one of the solder pads by spring force as soon as the soldered connection loses its strength and fails due to overheating. The soldered connection of at least one of the contact arms loses its strength at a lower temperature and is formed from a different alloy than the soldered connection that connects the power semiconductor to the printed circuit board. A method for populating a printed circuit board is also described.

A camera includes: (a) a printed circuit board supporting a first circuit component; (b) a second printed circuit board; (c) a PCB holder for holding the printed circuit boards spaced apart from each other and pivotable relative to each other; and (d) a housing for enclosing the printed circuit boards and the PCB holder, the PCB holder being dimensioned for fastening to the housing such that the printed circuit boards are not parallel to each other and the first circuit component is placed in thermal communication with the housing.

Provided is an electronic component including a pad region including a plurality of pads extending along corresponding extension lines and arranged in a first direction, and a signal wire configured to receive a driving signal from the pad region, wherein the plurality of pads include a plurality of first pads arranged continuously and a plurality of second pads arranged continuously, and extension lines of the plurality of first pads substantially converge into a first point and extension lines of the plurality of second pads substantially converge into a second point different from the first point.

An image sensor attached to a printed circuit board is installed in a camera. A holder includes first and second rails comprising first and second printed circuit boards, respectively, and the holder is fastened to a lens mount of the camera. The holder may be fastened to captively hold the image sensor, and the image sensor may be resiliently supported when captively held. A gripper grasps the image sensor proximate to the holder and aligns the image sensor to an aligned position of the image sensor relative to the lens mount. The image sensor may be moved to the aligned position after directing an image toward the image sensor to produce a processed image for determining relative alignment. The printed circuit board is soldered to the first and/or second printed circuit board such that the holder fixedly holds the image sensor so it is unmovable in its aligned position.

A camera has a lens mount and an image sensor for sensing images. A holder of the camera can captively hold the image sensor such that the image sensor is moveable relative to the lens mount when the image sensor is not attached to the holder. The holder is further operable to fixedly hold the image sensor such that the image sensor is unmoveable relative to the lens mount at an aligned position of the image sensor when the image sensor is attached to the holder. The image sensor may be attached to a printed circuit board. The holder may include first and second rails comprising first and second printed circuit boards, respectively. The holder is then operable to fixedly hold the image sensor by the printed circuit board being soldered to at least one of the first and second printed circuit boards.
