IPC: H01L21/60
Filed: 1990-09-13
Abstract: PURPOSE:To improve yield of manufacture by applying solder flux of a specified film thickness to a semiconductor chip mount surface when carrying out flip- chip-bonding of a semiconductor chip on a substrate and by performing flip-chip- bonding by soldering surely. CONSTITUTION:Protecting films 5, 5' are formed on two opposite sides of a periphery of a semiconductor chip mount surface 4 on a surface of a substrate 3 whereon a semiconductor chip is mounted. A stamping pin 1 is formed to have a larger width than a semiconductor chip mount surface 4. A solder flux 2 is transcribed from a solder flux table to a bottom of the stamping pin 1. It is pressed toward the substrate 3. Thereby, a bottom of the stamping pin 1 is partially brought into contact with the protecting films 5, 5' and the solder flux 2 is applied onto the semiconductor chip mount surface 4 in approximately the same thickness as the protecting films 5, 5'.

IPC: G11B21/08
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent degradation of speed control by temperature variation of VCM when idle seed of a magnetic disk device is performed by speed control using back electromotive voltage of a VCM(voice coil motor) actuator. SOLUTION: This is a timing chart showing that calibration of speed control is performed by reading out a track number on a magnetic disk medium and other control information properly and using them. After speed control by detecting back electromotive voltage of a VCM actuator is performed for a certain fixed time, feeding of a MR sense current and read-write-LSI are temporarily performed, positioning information on a magnetic disk medium is read out, and stability of control is secured by performing calibration of parameters used for speed control. Thereby, as positioning information on a magnetic disk medium is not always used, its operation can be controlled stably suppressing power consumption during idle seek operation. Use environment in which a portable system using a note type personal computer and the other magnetic disk device is operated with battery is improved.
