Title:
ELECTRONIC CIRCUIT BOARD FOR CLOCK
Document Type and Number:
Japanese Patent JPS6173086
Kind Code:
A
Abstract:
An electronic circuit board of very thin construction for a wristwatch employs a printed circuit board of insulating material with punched apertures for receiving and locating circuit components, such as capacitors, transistors and integrated circuits, which are of substantially the same thickness as the printed circuit board. A thin metallic conductive backplate is also provided with apertures and with bridging portions supporting the circuit components. Tabs on the backplate or on similar conductive clips for supporting circuit elements may be bent upward and extended through the circuit board apertures for making solder connections to discrete components or to conductive pads on the upper side of the printed circuit board. The backplate includes tabs for other purposes such as holding the backplate to the printed circuit board, making battery connections, providing switch terminals, and retaining the module under spring tension in the case.
