Abstract
Abstract A printed circuit board comprising, adjacent at least one of its edges and on at least one of its faces, conducting tracks adapted to co-operate with resilient contact members of a connector for receiving the board, the contact members being orientated in use parallel to the tracks, in which at least one of the conducting tracks has a concave cross section and is formed by a cavity in a rigid insulating support forming part of the board or in a male conductor associated with the board, the surface of the cavity having a coating of conducting material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
A printed circuit board comprising, adjacent at least one of its edges and on at least one of its faces, conducting tracks adapted to cooperate with resilient contact members of a connector for receiving the board, the contact members being orientated in use in alignment with the tracks, in which at least one of the conducting tracks has a concave cross section and is formed by a cavity in a rigid insulating support forming part of the board or in a male conductor associated with the board, the surface of the cavity having a coating of conducting material said cavity being of generally V-shaped cross section.
Claim 2
Dependent Claim
106 words
A printed circuit board comprising, adjacent at least one of its edges and on at least one of its faces, conducting tracks adapted to cooperate with resilient contact members of a connector for receiving the board, the contact members being orientated in use in alignment with the tracks, in which at least one of the conducting tracks has a concave cross section and is formed by a cavity in a rigid insulating support forming part of the board or in a male conductor associated with the board, the surface of the cavity having a coating of conducting material said cavity being of generally V-shaped cross section.
Claim 3
Dependent Claim
120 words
Printed circuit board comprising, adjacent at least one of its edges and on at least one of its faces, conducting tracks adapted to cooperate with resilient contact members of a connector for receiving the board, the contact members being orientated in use in alignment with the tracks, in which at least one of the conducting tracks has a concave cross section and is formed by a cavity and a rigid insulating support forming part of the board or in a male conductor associated with the board, the surface of the cavity having a coating of conducting material, said cavity being of generally V-shaped cross section, and in which the or each cavity surface is metallized to form the conducting track.
Claim 4
