Patent DE-4121107-A1 (DE)
Inventor: SCHWEIZER MATTHIAS
IPC: H05K3/34
Filed: 1991-06-26
Abstract: The invention relates to a method and an arrangement for soldering surface-mounted devices on printed-circuit boards. In the case of the known outer lead bonding methods, the positioning and soldering are carried out in two different systems. In addition, in the case of outer lead separations of 150  mu m, the soldering is carried out via single-lead soldering, using soldering irons or lasers. The device is thus not fixed onto the installation location at the start of the soldering process and is displaced during soldering. In order to avoid this disadvantage, the invention provides for multi-pole devices having an outer lead separation of up to < 150  mu m to be fitted and firmly soldered to the soldering point in one operation, in the correct position.

Title: Controlled auxiliary power supply for electricity meter testing - supplies intrinsic meter voltage path loads avoiding reduction in measurement accuracy
IPC: G01R35/04
Filed: 1991-07-24

Inventor: KIM BYOUNG YUN
IPC: H01L27/04
Filed: 1992-02-28
Abstract: A semiconductor integrated circuit device for suppressing power noises induced on a power line during high-speed operation of the device is described. On the rear side of a semiconductor substrate 10 having an integrated circuit formed thereon, a dielectric film 12 having a high permittivity is coated, to thus form a large capacitance Cb between a package lead frame 14 and the substrate 10. Thereafter, power having a polarity opposite to that of a power supply applied to the substrate 10 is connected to the lead frame 14 so as to form a decoupling capacitor between power terminals of a chip. Thus, power noises are decreased and a design area of the integrated circuit can be reduced. Another electric component, for example, a resistor or diode, may be formed instead of the capacitor.   <IMAGE>
