Component, positioning device and method for fastening the component by soldering

A method for fastening, by soldering, a component having electrical connection elements for making contact with a printed circuit board and at least one fixing element that is formed of plastic and mechanically fixes the component to the printed circuit board, wherein the at least one fixing element has a shaft which extends in an axial direction and at least one latch element on the shaft, comprising:

• providing the printed circuit board having at least one contact bore and having at least one capturing bore, wherein the at least one capturing bore at least has a diameter which is larger than a cross section of the fixing element, so that the shaft of the fixing element while extending in the axial direction perpendicular to the printed circuit board can be inserted into the at least one capturing bore without force;
• arranging the component on the printed circuit board with the electrical connection elements in the at least one contact bore and the shaft of the fixing element of the component while extending in the axial direction perpendicular to the printed circuit board in the at least one capturing bore of the printed circuit board without force, so that the shaft of the fixing element is positioned in the at least one capturing bore and the at least one latch element on the shaft extends completely through the at least one capturing bore;
• filling, while the shaft of the fixing element remains extending in the axial direction perpendicular to the printed circuit board and the at least one latch element on the shaft extends completely through the at least one capturing bore such that the at least one latch element is located completely below the surface of the printed circuit board, the at least one contact bore the liquid soldering material, or melting and solidifying a soldering material which is already located in the at least one contact bore and the at least one capturing bore, wherein the soldering material being solidified surrounds at least a portion of the fixing element within the at least one capturing bore to provide a mechanical connection of the fixing element to the printed circuit board, wherein the at least one latch element in combination with the solidified soldering material resisting subsequent movement of the shaft in the axial direction.
