Patent ID: 8278609

Claim:
A method for soldering a plurality of electrical connections, in which contact elements have to be soldered to soldered-connection faces positioned on a non-metallic glazing, the method comprising: providing a soldering tool configured to emit a magnetic field of a predetermined magnitude, the soldering tool including a loop or a coil having a magnitude and shape configured to correspond with a surface area on the non-metallic glazing that covers a region of plural soldered-connection faces and encompasses a plurality of solder spots to be heated simultaneously in a soldering operation; positioning the soldering tool with respect to the non-metallic glazing such that the magnetic field reliably heats the plurality of solder spots during the soldering operation; and performing the soldering operation on the non-metallic glazing by emitting the magnetic field of the predetermined magnitude by the soldering tool towards the plurality of solder spots simultaneously so as to heat the plurality of solder spots by induction, wherein a frequency of an AC voltage applied to the loop or to the coil is tailored to a connection geometry and set at least in a range of 5 to 150 kHz.
