Patent number: 6701611Abstract: The present invention provides an electronic component mounting apparatus which can reduce a consumption power amount in comparison with the background art, and a power supply control method which is executed by the electronic component mounting apparatus. A drive power source and a control power source are separately connected and shut-off in accordance with a command from a control device to each of component feed drive parts for driving component feed devices, a component transfer drive device for driving a component transfer device, and a circuit board positioning drive device for driving a circuit board positioning device. The control device detects an individual occurrence of halt condition of each of constitution parts of an electronic component mounting apparatus and shuts off the drive power source to the drive device in the halt condition. Thus, a wasteful power consumption is eliminated and the production is continued with a necessary minimum power.Type: GrantFiled: October 18, 2001Date of Patent: March 9, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Keizo Izumida, Takeshi Takeda, Kazuyuki Nakano

Patent number: 6678927Abstract: Surface mount capacitors are made having ultra-small dimensions of length, width and height. For example, capacitors of 0402 size and smaller may be produced having lower height than has been achieved in the prior art. The components have L-shaped terminations on respective ends thereof, providing bottom lands for mounting to a circuit board. At most, the component will have top lands of negligible size to provide a large gap width between the terminations across the top surface of the component. In some embodiments, the top surface may also include orientation indicia located thereon. The invention also provides improved methodology for terminating a capacitor or other surface mount component.Type: GrantFiled: September 29, 2000Date of Patent: January 20, 2004Assignee: AVX CorporationInventor: Gennady Retseptor
