SMD contact springs - type 4

contact springs are ideal for automatic assembly on printed circuit boards. They are soldered by the standard-reflow-soldering process.

The standard basic material used for contact springs is copper beryllium (CuBe). However, other materials can also be supplied.

As standard, springs are gold-plated (AU) and therefore provide excellent corrosion protection. They can be supplied in a wide range of dimensions and shapes.

  • Available in a variety of dimensions and shapes
  • Standard or customized -contact springs
  • Gold-plated, other platings are possible
  • Excellent connection properties
