An apparatus and method for providing an artificial standoff to the bottom of leads on a QFN device sufficient to provide a gap that changes the fluid dynamics of solder flow and create a unique capillary effect that drives solder up the of leads of a QFN device when it is attached to a printed wiring board (PWB).

Electronic modules and methods of fabrication are described. In an embodiment, an electronic module includes a molded system-in-package, and a flexible circuit mounted on a side surface of a molding compound layer such that the flexible circuit is in electrical contact with a lateral interconnect exposed along the side surface of the molding compound layer.

A solder member mounting method includes providing a substrate having bonding pads formed thereon, detecting a pattern interval of the bonding pads, selecting one of solder member attachers having different pattern intervals from each other, such that the one selected solder member attacher of the solder member attachers has a pattern interval corresponding to the detected pattern interval of the bonding pads, and attaching solder members on the bonding pads of the substrate, respectively, using the one selected solder member attacher.

A connector includes mounting tabs that are extended relative to traditional mounting tabs. On a back side of the printed circuit board (PCB), the mounting tabs connect to a back plate. The mounting tabs extend through the PCB and connect with the back plate, which provides improved structural integrity. Depending on the connector, the use of the mounting tabs can use existing mounting holes for the connector and remove the need for additional mounting holes.

Component mounting machine includes head, a device for moving head, transfer unit, and a mounting controller. Circular plate is an example of a container in which paste is placed. The bottom face of circular plate and the upper surface of the side wall have a predetermined height relationship. Height sensor is disposed on the lower face of head. Height sensor measures the height of the upper surface of the side wall of circular plate, which is a measurement point. The mounting controller recognizes the height of the bottom face of circular plate or the height of the surface of coating film disposed on circular plate from the height of the top surface of the side wall of circular plate measured by height sensor.

Various circuit boards with mounted passive components and method of making the same are disclosed. In one aspect, a method of manufacturing is provided that includes at least partially encapsulating a first plurality of passive components in a molding material to create a first molded passive component group. The first molded passive component group is mounted on a surface of a circuit board. The first plurality of passive components are electrically connected to the circuit board.

A composite wiring substrate includes a first wiring substrate including a first connection terminal, a second wiring substrate including a second connection terminal facing the first connection terminal, and a joint material joining the first connection terminal and the second connection terminal. The first outline of the first connection terminal is inside the second outline of the second connection terminal in a plan view. The joint material includes a first portion formed of an intermetallic alloy of copper and tin, and contacting each of the first connection terminal and the second connection terminal, and a second portion formed of an alloy of tin and bismuth, and including a portion between the first outline and the second outline in the plan view. The second portion contains the bismuth at a higher concentration than in the eutectic composition of a tin-bismuth alloy, and is separated from the second connection terminal.

A semiconductor package and a method of forming the same are provided. The semiconductor package includes a package substrate, a semiconductor device, an underfill element, and a groove. The semiconductor device is bonded to the surface of the package substrate through multiple electrical connectors. The underfill element is formed between the semiconductor device and the surface of the package substrate to surround and protect the electrical connectors. The underfill element includes a fillet portion that extends laterally beyond the periphery of the semiconductor device and is formed along the periphery of the semiconductor device. The groove is formed in the fillet portion and spaced apart from the periphery of the semiconductor device.

Power conversion modules using compression mount technology (CMT) connectors and associated apparatus and methods. Assemblies include a CMT connector that includes an array of spring-loaded CMT pins or contacts that are configured to contact respective pads on a pair of printed circuit board (PCBs), such as for VR module card or power conversion module and a motherboard. The power conversion modules in combination with the CMT connectors provide several advantages, including, a common VR module/power conversion module/motherboard footprint across OEM platforms and test hardware, just in time VR module attachment for improved inventory management, removable power delivery solution makes the platform more conducive to debug, in field servicing, and platform upgradable for higher power CPU/GPU/XPU.

An apparatus and method for providing an artificial standoff to the bottom of leads on a QFN device sufficient to provide a gap that changes the fluid dynamics of solder flow and create a unique capillary effect that drives solder up the of leads of a UN device when it is attached to a printed wiring board (PWB).
