Patent ID: 7833070

Claim:
A glazing comprising a ply of glazing material having a first electrically conductive component formed from an electrically conductive silver-containing ink mounted thereon, and an electrical connector, joined to the first electrically conductive component by a lead-free solder, the electrical connector formed from a copper strip having a thickness t and comprising first and second connector feet linked by a bridge portion, the bridge portion being at a height h above the base of each of the connector feet, wherein t is in the range 0.1 mm to less than or equal to 1.0 mm and h is in the range 1.0 mm to less than or equal to 5.0 mm wherein at least one of t or h are chosen to minimise the occurrence of stress faults in the glazing material in the region of the solder such that when the electrical connector is mounted on a piece of flat glass, t and h are chosen such that the maximum stress achieved is less than or equal to 12 MPa.
