    Abstract: PROBLEM TO BE SOLVED: To provide a bonding sheet which can mount an electronic part to a circuit board by a simple process and surely prevents shortcircuiting among electrode pads, and to provide an electronic circuit device using the same and its manufacturing method. SOLUTION: The bonding sheet 20 is formed by providing an adhesive filling portion 2 inside a base material 1 and filling the inside of the adhesive filling portion 2 with a conductive adhesive 3. The electronic circuit device 30 is formed by mounting an IC package 4 to a circuit board 7, wherein the bonding sheet 20 is interposed between the IC package 4 and the circuit board 7. A terminal electrode 5 is provided on the lower surface of the IC package 4, and an electrode bump 6 projects from the terminal electrode 5. A recess 8 is formed on the upper surface of the circuit board 7, wherein an electrode pad 9 is provided on the bottom of the recess 8. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide an insulating sheet which can prevent, in simple configuration, short-circuiting between terminals and can improve workability in mounting. SOLUTION: An insulating sheet 1 includes a sheet-like heat conduction part 2 provided between an FET 10 and a heat sink 20. Furthermore, the insulating sheet 1 includes a terminal housing part 3 continued with the heat conduction part 2. In the terminal housing part 3, a space 4 is formed for individually housing root portions 11a of terminals 11 provided in the FET 10. The root portions 11a of the terminals 11 of the FET 10 are housed so as to be embedded in the space 4. A silicone rubber is rich in flexibility, a front side of the space 4 is opened, and the root portions 11a are easily housed in the space 4. Thus, dust can be suppressed from being lying between the terminals 11; and short-circuiting between the terminals 11 can be prevented. COPYRIGHT: (C)2010,JPO&INPIT
