    Abstract: An arrangement may include a substrate and an electrical component. The electrical component may include a base made of an insulating material and a plurality of connection terminals. Each connection terminal is connected to a corresponding connection pad of the substrate by means of a spot of solder paste. The arrangement may further include a block interposed between the substrate and the base of the electrical component. The block may be located substantially on the axis of application of a force for actuating the electrical component and may be designed to inhibit deformation of the base. The block may include a spot of solder paste soldered to an associated conducting pad on the substrate.

    Abstract: A modified SMT (Surface Mount Technology) process is proposed for mounting an exposed-pad type of semiconductor device over a PCB (printed circuit board), which can help prevent the problem of floated soldering of the semiconductor device over the PCB. By this modified SMT process, a plurality of via holes are formed in the pad-mounting area of the printed circuit board; and a solder material is pasted over the bottom end of each of the via holes. As the semiconductor device is mounted in position over the printed circuit board, a solder-reflow process is performed on the pasted solder material so as to cause the pasted solder material to be wetted to the entire surface of the solder-wettable layer in each of the via holes, thereby allowing the solder material to reflow to the upper end of each of the via holes where the reflowed solder is also wetted to the exposed die pad of the semiconductor device, thereby securely bonding the semiconductor device to the PCB.

    Abstract: A pad array electronic device for mounting on a substrate, such as a printed circuit board (PCB), has a relatively rigid package body with a plurality of holes bearing connecting mechanisms for bonding to lands on the PCB. The package body may be a thermoset plastic or other material that can be injection molded around an electronic component, such as an integrated circuit (IC) bonded to a lead frame. An integrated circuit die or other electronic component is mounted in proximity with or on the lead frame and electrical connections between the integrated circuit chip and the frame are made by any conventional means. In one aspect, the substrate leads are provided at their outer ends that are exposed by holes in the package with solder balls or pads for making connections to the PCB. The package body may be optionally used to stand off the device a set distance from the PCB so that the solder balls will form the proper concave structure. The periphery of the package body may function as a carrier structure to protect the lead or connection structures during testing, handling and board mounting. The open vias permit back side testing of the device before or after mounting of the package to the PCB. Additionally, a heat sink structure and/or capacitor may be directly bonded to the side or the top of the pad array electronic device which may be used singly or in multiple, stacked configurations, to facilitate the thermal dissipation from the device.
