Abstract
A soldering method is provided. According to the method at least two sets of components are heated and soldered by heating. Each set includes a first soldering partner, a second soldering partner, and a solder. During the soldering process, the individual temperatures of each one of the sets are transmitted by a radio frequency transmitter to a receiving and control unit. The control unit controls the heating of the sets depending on the transmitted individual temperatures.
Claims24
A soldering method comprising:
- providing a soldering machine comprising a heating chamber with an induction heating unit operable to, provide energy and at least one cooling chamber with a cooling unit,
- providing at least two sets of components to be soldered, each set comprising a first soldering partner, a second soldering partner, and a solder;
- positioning each one of the sets of components with its solder arranged between its first soldering partner and its second soldering partner inside the heating chamber,
- providing for each one of at least two of the sets a temperature measuring unit individually assigned to the respective setwhere said temperature measuring unit is positioned inside or on a surface of one of the components in the respective set;
- providing a wireless radio frequency transmitter and a wireless radio frequency receiver,
- providing a control unit coupled to the wireless radio frequency receiver, the control unit operable to control the induction heating unit;
- transmitting for each one of the temperature measuring units temperature information on the temperature of one of the soldering partners of the respective set of components to the wireless radio frequency receiver by the wireless radio frequency transmitter;
- heating the sets of components by the energy provided by the induction heating unit;
- controlling the energy provided by the induction heating unit via the control unit based on the temperature information;
- passing all sets of components, after the solders of all sets have been heated up to at least their respective melting points, from the heating chamber into the cooling chamber;
- and
- cooling the sets of components via the cooling unit by controlling the cooling unit based on the temperature information.
