Title: Bga package and its manufacture
Inventor: OBA AKIRA
IPC: H01L23/12
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce the thermal stress which occurs in a BGA package when the package is mounted on a printed board by reducing the size and weight of the package by fixing a metallic sheet to a plastic board so that the metallic plate may cover at least the opening of the plastic board and partially exposing the surface of the plastic board to which the metallic plate is fixed. SOLUTION: On the upper surface of a plastic board 2 having a cavity 6 for housing an IC chip 7, a wiring pattern which is formed by etching copper foil and ball pads 5 are arranged and solder balls 4 are welded to the pads 5. On the lower surface of the board 2, a Cu heat sink 3 is stuck in such a way that the side section 2a of the lower surface of the board 2 is exposed. After wires 8 are connected to the chip 7, the cavity 6 is sealed with a resin 9. Since the heat sink 11 is not stuck to the whole lower surface of the board 2, namely, since the heat sink 11 is stuck in a partially removed state, the volume of the heat sink 11 is reduced and the whole weight of a BGA package can be reduced.

IPC: B41J2/05
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To maintain a high quality image for a long time by removing a burnt residue on a heater. SOLUTION: A bubble is generated in a liquid in an individual passage 3 by heating of a heater 7 to be grown, then a liquid drop 13 is ejected by the pressure at that time, thereby performing the recording. After that, the bubble is immediately shrunk by the stopping of the heating, then resupplying of the liquid is executed. At that time, the liquid supplied via a common liquid chamber 4 and a common liquid passage 11 advances on the heater 7 by exceeding a wall section 10. As the liquid meanders by exceeding the wall section 10, a turbulent flow is generated on the heater 7. The surface of the bubble is disturbed by the turbulent flow, so that the bubbles is divided into a plurality of pieces. The divided bubble pieces are disappeared at respective positions on the heater 7.  As a result, a cavitation force is generated on each of the positions on the heater 7, so that a burnt residue can be removed.

Abstract: PURPOSE:To obtain high detection accuracy regardless of the concn. of specimen gas using a detector having a compact size, by making the quantity of infrared rays emitted to the specimen gas in a measuring cell convertible. CONSTITUTION:When infrared rays are emitted from an infrared ray radiation source 3, a light modulator 7 permits the 100%-transmission of infrared rays at first. Next, said infrared rays reach a half mirror 16 and reflected by 50% from said mirror 16 to be incident on an infrared detector 15 while the remainder transmits therethrough to be incident on an infrared detector 4 through a measuring cell 2. The detection signals from the detectors 4, 15 are respectively amplified by amplifiers 6, 18 to reach a control means 8. The control means 8 judges whether the magnitude of the detection signal obtained by the detector 4 is present in a predetermined range high in detection accuracy and, when said signal is out of said range, the modulation of the quantity of infrared rays emitted is indicated to the light modulator 7 so that the magnitude of the detection signal enters the predetermined range and a component to be inspected is operated so as to obtain a predetermined value based on the detection signal obtained in the highly accurate range of the detector 4. The detection value thus obtained is displayed on a display device 9.
