Pogo-pins – the best tool for field testing
Pogo pins (spring pins) are a type of electrical connector mechanism. It is widely used in many applications in electronic systems and industry. Most often, pogo-pins are used in factories for mass testing of electronics. The genesis of the name "pogo pin", "pogo-pins" is interesting. It comes from the similarity of this connector to some toy - pogo stick.
The operation of the pogo pin is, contrary to appearances, very simple, but extremely effective and convenient. An integrated spiral spring in the pin exerts a constant normal force on the back of the contact plate at the end of the pin. Pins are applied to different parts of the tiles to test their properties. Thanks to a special mechanical structure, pogo-pins counteract any undesirable movement of elements. By using other technologies, we could run the risk of causing an intermittent connection.
For the above reasons, pogo-pins are recognized as the most durable and effective techniques for rapidly testing electrical contacts. It is important that such connections are fully resistant to mechanical shocks and vibrations. The ends of these pins are usually turned. The production process is therefore a bit longer (no molds are used), but thanks to this, you can create many different pogo-pins that will be very precise, making it easier to test different types of electronic parts.
A wide selection of best pogo-pins – different shapes & ends
Electronic devices have newer and newer plugs, terminations and individual printed circuit boards. Depending on the shape of the test field, various shapes of test tool tips are used - pogo-pins. As we have mentioned before, the machined manufacturing of these tools favors the creation of extremely precise test tips. Pogo pins with slightly rounded or slightly pointed ends are most often used. These types of tools are perfect for contact with flat test fields or guides. Different types of test fields will typically require pogo pins with slightly pointed tips so that they are able to penetrate the flux layer or dirt build up on the printed circuit board test surface. Moreover, some test pins have concave ends that allow easy access to the feet of the electronic components and other endings.
Pogo-pins in testing systems – additional testing methods
Certainly, the use of pogo-pins is not just for embedded systems, automated testing of printed circuit boards and other electronic systems. Pogo pins are elements that can also be used at home to check the operation of various electronic parts. In addition, they are also used to construct tight joints. For this, it is enough to stick the pin through the housing so that you can connect a charger or other external device to it.
Pogo pins are also readily used to make connections between printed circuit boards in multi-board systems. Then a solder pad is placed on one PCB (preferably when they are gold-plated or soldered with special gold-plated plates), and pogo-pins are soldered on the other. The advantages of this method are the possibility of quick assembly and disassembly of individual PCBs or increased resistance to vibrations. Choose the highest quality pogo pins for testing electronics. Purchase a single pogo-pin or opt for a pack of 10 pogo pins. If you have any questions, feel free to contact us.
