What Are The Basic Requirements Of Spring Contact Test Probes?

The test probes are the generic terms used to describe a component whose spring loaded tips will provide a reliable electrical contact to a target distance. The traditional use of spring contact test probes can make contact with printed circuit boards or electrical components, in order to test the functionality and measure the value of the components. They are mostly used in the vacuum test fixtures associated with automatic test equipment and used in a functional test station as part of a larger production line. Here, the test probe is comprised with a metal tube, ready to assemble with a spring and contact plunger, it supplied as a one-piece item.


The test probes are usually referred as an excellent electrical conductor and is resistant to corrosion. Here, the electrical cable is generally connected to a receptacle in which the test probes insert into. The use of a receptacle in the spring contact test probes allows the test probe to be removed for cleaning or replacement without having to disconnect the electrical cable. The spring contact probes are used to make contact with the various test points on printed circuit boards, components and wiring fields. When it employed in special test modules, the spring test tubes can be used to test the connection-cable systems and also used in control engineering units or as a charging contact.


The contact test probes have the plunger tip styles that can be used to provide a variety of tip styles and different spring pressures. This ensures the spring contact test probes to contact with the test surface. The test probes can also be mounted with the receptacles, where the electrical connection of the probe is made and allows the test probes to easily remove for performing the repair or replacement.

Different Standards And Special Models For Spring Contact Probes

The spring contact probes are used to create an electrical connection between the object that to be tested and the testing system. These contact probes are primarily used for electrical testing of printed circuit boards, connectors, cables and various other electrical components and assemblies. The main advantages of the spring contacts are:
·         Constant contact resistance.
·         High pointing accuracy.
·         Longevity.
·         High currents and frequencies as possible.
·         Easy installation in the test adapter by using receptacles
·         Interchangeable.

Moreover, the spring contact probes are used to test the printed circuit boards, connectors, wire harness and other electronic components. They can be used in interfaces and easily removable electrical connections. The contact probes of springs do not require tolerance compensation because they are suitable for all contacting requirements in two-terminal measurement. Altogether, the contact probes of spring produce different materials such as brass, steel or copper beryllium. It contains a broad range of head shapes with a diameter between 0.5 and 3mm forms of your standard product range.

In addition to this, the contact probes produce individual spring and testing probes with head shapes, that have diameters ranging from 0.25 to 10mm. The vertical range of manufacturer enables to deliver and produce the contact probes of spring in small quantities and it can also add the standard contact probes from a different range of products to include individual models for the specific tasking tasks.
The spring contact probes which are often have spring loaded contact pins that are mainly used in the testing of printed circuit boards. The spring contacts built the electro-mechanical connection between the test system. The spring contacts are mounted in receptacles which are mounted in the test fixture. Through this mounting system, it can quickly exchange it without the wiring have to be replaced. Probes are a durable component, which can perform several thousands of contact cycles with a stable contact resistance. The longevity has led to the spring contact pins in the testing of printed circuit boards are unrivaled.
