Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
182 words
A method for fixing a resonator casing having a longitudinal axis to a printed circuit of a timepiece, said printed circuit comprising an insulating substrate and a conductive layer forming a plurality of conductive tracks, the method comprising the steps of: forming in said insulating substrate an opening having a shape that enables said casing to be inserted at least partly therein; forming in said conductive layer at least one fixing lug means integral with said layer, said fixing lug means extending over said opening and over at least a portion of such a casing; inserting said casing in said opening; shaping said at least one fixing lug means to form a cradle for said casing by engaging said casing in said opening with said longitudinal axis substantially parallel to the plane of said opening and bringing said casing into contact with said at least one fixing lug means to deform said at least one fixing lug means into said cradle; and mechanically joining said at least one fixing lug means to the portion of said casing in contact with said cradle.
Claim 2
Independent Claim
182 words
A method for fixing a resonator casing having a longitudinal axis to a printed circuit of a timepiece, said printed circuit comprising an insulating substrate and a conductive layer forming a plurality of conductive tracks, the method comprising the steps of: forming in said insulating substrate an opening having a shape that enables said casing to be inserted at least partly therein; forming in said conductive layer at least one fixing lug means integral with said layer, said fixing lug means extending over said opening and over at least a portion of such a casing; inserting said casing in said opening; shaping said at least one fixing lug means to form a cradle for said casing by engaging said casing in said opening with said longitudinal axis substantially parallel to the plane of said opening and bringing said casing into contact with said at least one fixing lug means to deform said at least one fixing lug means into said cradle; and mechanically joining said at least one fixing lug means to the portion of said casing in contact with said cradle.
Claim 3
Dependent Claim
41 words
A method according to claim 1, wherein said casing has an end surface substantially perpendicular to said longitudinal axis, said casing being engaged in said opening, said end surface of said casing being in contact with an edge of said opening.
Claim 4
Dependent Claim
23 words
