Spring Loaded Test Pins

Spring-loaded test pins are used for testing printed circuit boards (PCBs) and other electronic components. They are required to interface the main tester with the board being tested. It will have a main connector connected to the test instrument and a separate pin / probe / or “nail” wire removed from the connector, which is in contact with the desired node on the board.

When the spring-loaded test pins are used, it is necessary to make a test mold according to the wiring condition of the tested PCB board, and in general, a mold can only test one type of PCB board; when the test spring pin is used, it needs to have enough pins;

Vibration and shock resistance of high-quality Spring loaded test pins: The vibration and shock resistance of high-quality pogo pins are important properties of electrical connectors. It is especially important in special application environments such as aerospace, rail, and road transport. It is an important indicator to test the firmness of the mechanical structure of the electrical connector and the reliability of the electrical contact. 

Salt spray resistance of high-quality pogo pins: When high-quality pogo pins work in a humid and salty environment, the metal structure and surface treatment layer of the contacts may cause electrochemical corrosion, affecting the physical and electrical properties of the connector.

To evaluate the ability of electrical connectors to withstand this environment, a salt spray test is prescribed. Hang the connector in the temperature-controlled test box, and spray the sodium chloride solution with the specified concentration with compressed air to form a salt mist atmosphere. at least 48 hours.

The relevant test methods are specified. The shock test shall specify the peak acceleration, duration, and shock pulse shape, as well as the time of interruption of electrical continuity.

Other Product model: pogo pin current probe, high product positioning accuracy, stable product overload, low product test false positive rate, mainly used in smart products, Bluetooth headsets, and Bluetooth bracelets. This pin is usually used for smartwatches, and there is a charging function on Bluetooth headsets.
