  • SMD surface mounted devices
  • the circuit board interspersed with conductor tracks is first attached to an already formed circuit board Provide contact fields (lands, connector pads, contact pads) with a solder paste made from a powdery tin-solder compound and a flux (for example printed in a screen or stencil printing process).
  • the subsequently applied SMDs temporarily adhere to the circuit board due to the solder paste.
  • the solder paste is melted with outgassing of parts of the flux.

  • the circuit board is a carrier for an electrical circuit with one or more electrical lines and possibly electrical components which have been applied to the circuit board, for example in the reflow process.
  • the support element can consist entirely of tin, which has been completely or partially liquefied during the reflow process, and which rests directly on a contact surface of the circuit board.
  • the contact area (English, connector pad, contact pad) is a predetermined area for the position of the support element in the context of the reflow process, at which one or more conductor tracks on the surface of the circuit board end.
  • the support element has a height of at least 50 micrometers and at most 150 micrometers above the circuit board in order to ensure a vibration-resistant contact.
  • the contact is made by placing a conductor on the surface of the support element. Vibrations and / or shocks, caused for example by the movement of a vehicle encompassing the circuit board and the conductor, can lead to mutual movements of the support element and the adjacent conductor. As a result of the movements and / or pressure of the conductor on the support element, material can be removed from areas of the surface of the support element.
  • the height of the support element above the circuit board is advantageously chosen so that long-term contact is ensured.
  • the support element has one of the following base areas:
  • a base area is advantageous for attaching the contact point to the circuit board, for securing a position of an electrical conductor adjacent to the contact point and / or for producing the support element, for example as a solder preform.

  • one end of the contact spring rests against a surface of the support element, the surface of the support element being larger than the cross-sectional area of the adjacent end of the contact spring.
  • a surface of the support element protruding beyond the cross-sectional area of the contact spring can, for example, ensure a tolerance for a position of the end of the contact spring, in particular also under vibration or shock.
  • a vibration of the end of the contact spring can be used to advantage in order to counteract corrosion and / or oxidation of the surface of the support element by removing parts of the surface.
  • the surface of the support element has a depression and / or a curvature, which are designed to secure a position of the abutting end of the contact spring.
  • the depression can be trough-shaped, or it can be adapted to the cross-sectional contour of the contact spring in a ring shape and enclose a central curvature.

  • the component has an actuator and / or a sensor, the contact producing an electrical connection between the actuator and / or the sensor and the circuit board in a utility vehicle.
  • the present invention also relates to a method for producing a printed circuit board with a contact point, comprising the following steps:
  • the applied support element advantageously melts in the reflow process, so that direct contact is made with the conductor coming to the surface in the contact field of the circuit board.
  • the at least partial melting of the support element in the reflow process represents a compromise between the standard of applying an SMD and the standard of tinning.
  • the application of the support element includes printing the contact field with a solder paste, with existing solder liquefiers being used up to such an extent that they do not reduce the conductivity of the contact point when a conductor adjacent to the contact point is contacted.
  • the solder paste contains a flux which, when heated during the reflow process, emerges and leaves residues and / or, for example, can form on the surface of the solder, which can increase the conductivity of the Affect contact point. This would be the case in particular if the support element was dispensed with to form the contact point and, for example, only a solder paste was used. By suitable heating and / or by choosing a suitable geometry of the support element, such as, for example, a sufficient thickness, residues of additives on the surface of the contact point can be prevented.
  • At least one surface-mounted component is to be attached to the circuit board during the method, the step of connecting being a simultaneous soldering of the support element and the surface-mounted component.
  • the attachment of the contact point can thus be integrated into an existing reflow method for attaching surface-mounted components without requiring the introduction of additional method steps in the reflow method.
  • the tin of the support element can also contain additives such as lead, zinc, silver, iron, antimony, copper or a flux, which have a function of the support element as a contact point for applying an electrical conductor and / or a method for applying the support element to the Influence the printed circuit board advantageously without changing the mentioned features of the contact point or the method.

  • Such conductor tracks can consist of copper, for example. Since oxidation processes impair the contactability of exposed copper over time, in one of the last method steps for producing the printed circuit board 100, the contact surface 110 is coated with an end surface (finish) made of, for example, tin, silver or gold.

  • the printed circuit board 100 can, for example, be part of a sensor in a braking system of a vehicle.
  • An end surface of the contact surface 110 made of tin can, for example, have a thickness of one micrometer before the application of the support element 200. During the reflow process, this thickness is typically reduced, for example by 0.2 micrometers. This thickness would be insufficient for a contact spring 300 to be applied, since, for example, corrosion, oxidation and, when the contact spring 300 is in contact, also abrasion processes corrupt the end surface too quickly.
  • the support element 200 can advantageously have a height in a range of 50 to 150 micrometers above the circuit board 100, and thereby ensure long-term contact and protection of a conductor track of the circuit board 100 that ends at the contact surface 110. Since during the reflow Method can be partially reduced, the support element 200 has a greater height (for example by 10 to 50 micrometers) before it is placed on the contact surface 110 of the circuit board 100.

  • the reflow method can include the assembly of further components on the circuit board 100. In this way, the application of the contact point can be integrated into an existing reflow process without requiring the introduction of an additional process step.
