## Abstract

A glazing is provided comprising at least one ply of glass having an electrically conductive component connected to an electrical connector by a soldered joint. The solder has a composition comprising tin and silver, preferably 98Sn2Ag. The solder is lead-free. The connector is nickel plated and comprises copper, preferably 99 to 99.99 wt % Cu. Samples according to the present invention did not develop cracks in the glass during temperature cycling testing.

## Claims

### Claim 1

A glazing comprising at least one ply of glass having an electrically conductive component on at least one surface, and an electrical connector electrically connected to the electrically conductive component through a soldered joint, the solder of the joint having a composition comprising tin and silver, wherein the electrical connector comprises a nickel plated contact for contacting the solder.

### Claim 2 (depends on 1)

A glazing as claimed in claim 1, wherein the solder has a composition comprising 0.45 wt % or less indium.

### Claim 3 (depends on 1)

A glazing as claimed in claim 1, wherein the solder has a composition comprising less than 0.1 wt % Pb.

### Claim 4 (depends on 1)

A glazing as claimed in claim 1, wherein the solder has a composition comprising 0.5 wt % or more silver.

### Claim 5 (depends on 1)

A glazing as claimed in claim 1, wherein the solder has a composition comprising:
90 to 99.5 wt % Sn, and
1 to 10 wt % Ag.

### Claim 6 (depends on 1)

A glazing as claimed in claim 1, wherein the solder has a composition comprising less than 5 wt % Cu, preferably less than 0.1 wt % Cu.

### Claim 7 (depends on 1)

A glazing as claimed in claim 1, wherein the electrically conductive component comprises electrically conductive silver-containing ink.

### Claim 8 (depends on 1)

A glazing according to claim 1, wherein the electrical connector comprises copper, preferably 99 to 99.99 wt % Cu.
