Abstract:
The method of surface mounting radio frequency components includes using at least one radio frequency component having a pair of input/output contact points or areas at corners on the underside of the component, wherein each of the input/output contact points or areas abuts the adjoining edges of the corners. The component is positioned relative to a pair of traces on a circuit board for enabling an electrical connection thereto in a range of angular dispositions. By using a single non-customized component, adjacent components can be configured with a signal flow path of a range between about 0.degree. (a chain configuration) and about 180.degree. (a "U"-turn).
Abstract:
A method of affixing a passive dielectric component to a printed circuit board comprising the steps of forming a metallised area on the p.c.b. separate from the printed electrical circuitry, forming a like metallised area on the component, applying solder material to one of the metallised areas, placing the component on the metallised area on the board and reflowing the solder to create a metal-solder-metal bond between the component and the p.c.b. whereby the component is accurately aligned with respect to the printed electrical circuitry on the p.c.b.
Abstract:

The amplifier circuit is provided on the other surface of the printed circuit board for selectively amplifying oscillatory outputs from the oscillator circuits. The dielectric resonators are fixed to a metal plate mounted on the printed circuit board, and the amplifier circuit is located at a position opposite to the metal plate.
Abstract:
A mounting entity comprises, in layered order, a pressure sensitive adhesive, a foam spacer, a second pressure sensitive adhesive, a filler, and a heat sensitive adhesive. The first pressure sensitive adhesive is attached to an electrical component which is then mounted upon a printed circuit with the heat sensitive adhesive in contact therewith. The passing of the board over a solder wave heats the top surface of the board to a temperature high enough to activate the heat sensitive adhesive and adhere the component to the board. The intermediate foam layer dampens shock and vibration.

Abstract:
A base of a surface-mount electronic component package holds an electronic component element and is to be mounted on a circuit board with a conductive bonding material. The base has a principal surface and an external connection terminal to be electrically connected to the circuit board. The external connection terminal is formed in the principal surface. The base includes a bump formed on the external connection terminal. The bump is smaller than the external connection terminal. The base has a distance d between an outer periphery end edge of the external connection terminal and an outer periphery end edge of the bump along an attenuating direction of stress on the external connection terminal The stress is generated in association of mounting of the base on the circuit board. The distance d is more than 0.00 mm and equal to or less than 0.45 mm.
