How the quality Spring Contact Probes is important than the quantity?

Spring contact probes are used to test printed circuit boards, wire harnesses, connectors and other electronic components. Moreover, they can be used in interfaces and as easily removable electrical connections. Spring Contact Probes are used to make contact to various test points on printed circuit boards (PCB’s), components and wiring fields. When employed in special test modules, the probes can be used to test connector-cable systems. The probes can also be used in control engineering units or as a charging contact. These are made up of a tubular barrel, a spring and a plunger. Plunger tip styles can be provided in a variety of tip styles and different spring pressures. This ensures the best contact with the test surface. This also allows the probes to be easily removed for repair or replacement.

Contact Probes are available for various applications. Besides the technical applicability also machining and economical facts are relevant for this decision of using the contact probe. Short travels probes are solid probes with a limited travel facility .They are frequently used as battery or charge contact. Additionally, short travel probes can be integrated in end user products whenever low-wear electrical contacts are demanded. Other categories are Interface Probes, Probes with rolling ball, Switch Probes, High Current Probes, Threaded Probes; Pneumatic Probes etc. flat tip pin size contact probe is suitable for solder pads and contact pins. Different uses of contact probes are there according to the tip pin size. High current probes are used for high current application, specially designed for a very small probe resistance.

The main advantages of spring contact probe are longevity, Constant contact resistance, Interchangeable, Easy installation in the test adapter by using receptacles, High pointing accuracy, High currents and frequencies possible. Probes are a durable component, which can perform several hundred thousand contact cycles with stable contact resistance. The variety of spring contact probe allows the user to find the perfect test needle for each application.  Each probe is used for different purposes. The users have to choose according to the tip style, length, spring force and travel time. The wide range of applications for spring contact probes includes board tests with fine centers up to wire harness and connector test with individual and.
