Title: Connecting method for electronic part by solder bump
Inventor: KUBOTA TAKASHI
IPC: H01L21/60
Filed: 1993-12-22
Abstract: PURPOSE:To provide a method for connecting electronic parts through solder bumps that achieves reliable connections at low cost, by improving a cream solder printing process to form bumps in specified positions almost into an hourglass shape (waist shape). CONSTITUTION:An electronic part having solder bumps formed thereon is connected by solder reflow to a board having pads for connection formed thereon. In this method more cream solder 13-1 is applied to the pads 12-1 for connection positioned in the inward area on the printed wiring board 11 than to those positioned outside them. A semiconductor chip 14 is positioned and placed on the printed wiring board 11, and then solder reflow is performed. Thus melted cream solder, larger in quantity, on the inner pads pushes up the semiconductor chip 14, and accordingly, melted cream solder 15a-3, smaller in quantity, on the outer pad 4 is formed almost into an hourglass shape.

Abstract: PURPOSE:To operate a charge wire cleaning device only once a day by providing a timepiece for outputting the present date data and a storage means for storing the date data at the time of cleaning and updating and storing the present date data in the storage means only in case of both the date data are different, when a power source of an image forming device is turned on. CONSTITUTION:When a power source switch 305 of a copying machine is turned on, an ON-signal of the power source switch is inputted to a CPU 301, and at that time, by data of a RAM 302 and a timepiece IC 303, a control signal of a driving motor 15 for cleaning a charge wire is outputted to a motor driving circuit 304 from the CPU 301. After the power source switch 305 of the copying machine is turned on, the CPU 301 decides whether a date has changed from the time of the previous cleaning or not, and unless the date changes, it remains as it is, and when the date has changed, the cleaning motor 15 is brought to forward turn for a prescribed time, and thereafter, it is brought to reverse turn for the same time and stopped. In such a way, even when the power source switch is turned on/off many times in a day such as a miniature copying machine, it becomes unnecessary to clean excessively the charge wire as in the past.
