The resistive heating configuration of generation or it is integrated on a glass or in electronic building brick, such as antenna amplifier antennafire, tuner, LED or biography
Sensor.
Used coating usually has good electric conductivity, the heating of glass plate is realized, so that the glass plate can be protected
It holds and is free of ice and condensed water.These coatings include herein conductive layer, are based particularly on silver.Its usually with two bus-bars（?
Referred to as collector or busbar）Electrical contact, electric current flow through heatable coating between them.The heating of this mode for example describes
In 03/024155 A2, US 2007/0082219 of WO in A1.
The common problem of windshield with electrical component is the connection of itself and service voltage.In order to contact composite glass
Various components, usually bus-bar made of the conductive screen-printing paste argentiferous is printed onto on glass baseplate.This remittance
Stream has relatively high surface resistance after coming printing on the glass substrate.By firing, by most band-like and long narrow manufacture
Bus-bar is fixed on the glass substrate.For aesthetic reasons, it is arranged in the outer edge of transparency glass plate nearby and covers not
Under clear edge coating.Although the firing of the argentiferous screen-printing paste on a glass improves the electric conductivity of bus-bar,
When big number of packages produces it is especially very expensive and energy-intensive for economy point.In addition, this manufacturing step is wanted
