Abstract:
Electronic devices may contain electrical systems in which electrical components are mounted on a substrate such as a printed circuit board. The electrical components may include surface mount technology components. Multiple surface mount technology components may be stacked on top of each other and beside each other to form an electrical component that minimizes the amount of area that is consumed on a printed circuit board. Noise suppression circuits and other circuits may be implemented using stacked surface mount technology components. Surface mount technology components placed on the printed circuit board may be pushed together and subsequently injection molded to form packed component groups. An integrated circuit may be mounted to the printed circuit board via an interposer and may cover components mounted to the printed circuit board. An integrated circuit may be mounted over a recessed portion of the printed circuit board on which components are mounted.

Abstract:
A sensing unit package (20) with reduced size and improved thermal sensing capabilities. An exemplary package includes a printed circuit board (24) with a plurality of electrical traces, an application-specific integrated circuit (Analog ASIC) chip (26), and a micromachined sensor (28) formed on a microelectromechanical system (MEMS) die. The Analog ASIC chip is electrically and mechanically attached to the printed circuit board. The MEMS die is in direct electrical communication with only a portion of the electrical traces of the printed circuit board and is mechanically and thermally attached directly to the Analog ASIC chip. A thermally conducting compound (36) is located between the MEMS die and the Analog ASIC chip. One or more solder balls (32) electrically attach the Analog ASIC chip to the printed circuit board and one or more solder traces electrically attach the MEMS die to the printed circuit board.

Abstract:
Electronic parts are mounted on a circuit board (1) on which interconnection patterns are formed. Of those parts, particular field-effect transistors (FET) (2) that are likely to become hot are adjacent to a temperature-sensitive fuse (4) that breaks a circuit when the temperature of the electronic part rises. The circuit board (1) includes A through hole (1a) in the area where the FETs (2) are mounted. The FETs (2) are laid over the through hole (1a) on the front side of the circuit board (1). The temperature-sensitive fuse (4) is partially inserted in the through hole (1a) on the backside of the FETs (2), which is filled with heat-conducting resin (3) such as silicone. This circuit board can be thin, including parts mounted on it, without using a thinner board. Therefore, such a board with a temperature-sensitive fuse can be used in notebook computers that usually have only a limited space. This circuit board also provides a mounting structure for a temperature-sensitive fuse that is sensitive to the temperature of parts to break circuits if abnormal temperature is detected.
