Title: Bump-forming method and device
Inventor: YAMAMOTO AKIHIRO
IPC: H01L21/60
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To obtain a bump-forming device of a structure, where a bump-forming contact time is made quicker than that in conventional bump-forming methods and a bump of a shape, which will not crush excessively can be formed, and a bump-forming method. SOLUTION: A ball 45 is made to descend at a first speed, until a position immediately before the ball 45 is brought into contact with an electrode 47 by a control unit, and the ball is made to descend while the first speed gradually slows down from the position immediately prior to the position of the contact of the ball 45 with the electrode 47. Thereby, the first speed when the ball comes into contact with the electrode is slowed down. Hereby, a bump to be formed can be prevented from being crushed excessively. Moreover, since the pressing force of the ball to the electrode and the strength of ultrasonic waves are changed and the bump is formed according to the progress of the diffusion of the crushing of the bump, a bump-forming contact time per one bump can be speeded up, as compared with that in the conventional bump-forming methods.

Title: Heat-resistant and corrosion-resistant multi-layer plated steel material
Inventor: TAKAHASHI TERUHISA
IPC: B32B15/01
Filed: 1988-10-29
Abstract: PURPOSE:To obtain multi-layer plated steel material having both high-performance corrosion resistance and heat resistance by a structure wherein nickel-plated layer having the specified layer thickness as lower layer, zinc-nickel alloy-plated layer and chromate film are made in the order named onto the surface of steel material. CONSTITUTION:The heat-resistant and corrosion-resistant multi-layer plated steel material concerned is produced by making nickel-plated layer having the layer thickness of 0.2-10mum, zinc-nickel alloy-plated layer and chromate film in the order named onto the surface of steel material or of steel material having the surface with copper layer thereon. If the layer thickness of nickel plating applied as the lower layer is below 0.2mum, the covering power to the steel substrate becomes poor and no remarkable improvement effect of heat- and corrosion-resistances is realized. Further, if the layer thickness exceeds 10mum, separation, crack and the likemay occur at pressing, bending or the like, resulting in expecting no improvement of corrosion resistance in proportion to the thickness of the plated layer. The thickness of the nickel-plated layer is preferably processed to be in the range of 0.2 - 10mum. The nickel content in the zinc-nickel alloy plated layer is preferably set to be in the range of 12- 15% from the viewpoint of corrosion resistance.
