An elongate opening is formed in the substrate of the printed circuit, from which project lugs formed in the copper layer on the substrate. The lugs are shaped to form a supporting cradle for the resonator which is soldered or stuck to the lugs with its base in contact with the end of the opening. Two conductive tracks extend across the opening to two resonator terminals, in the form of pins, to which they are soldered.

Method of attaching a resonator casing to a printed circuit

An electronic watch module and method of manufacturing the module. The module is formed from a flexible film by forming a set of appropriately located, sized and shaped component openings in the film, forming a second set of terminal lead bonding openings for the components, securing a metallic foil to said film, removing portions of said foil to form a pattern of interconnection leads for said components leaving portions over said bonding openings, locating the components in the respective openings with the component leads in registry with their respective interconnection leads, and bonding the foil leads to the component leads through the bonding openings.
