Product Details

Rolling Ball Pogo Pins, also known as pogo pins or Pogo Pin connectors, or Rolling Ball spring-loaded Pins, their core function is to conduct electricity or signal transmission.

The internal design of Rolling Ball Pogo Pins adopts a bevel structure and a built-in spring mechanism. It is mainly composed of four core components: Rolling Ball, Solid Pin, Spring and Body, and is assembled through precision molds and special equipment. The design purpose of the inclined plane structure is to ensure that when the Pogo Pins are working, the lateral force generated by the contact between the inclined plane and the spring is used to push the Rolling Ball to maintain a stable contact force with the inner wall of the Body, so that the current path mainly passes through the gold-plated rolling ball and Body. In order to obtain stable and extremely low contact resistance, a stable and reliable connection can be maintained even under frequent plugging and unplugging.

How to install Rolling Ball Pogo Pins:

SMT automatic patch reflow technology: The SMT automatic patch machine automatically mounts Rolling Ball Pogo Pins onto the PCB circuit board with solder paste printed on it. The solder pins are accurately inserted into the PCB circuit board holes, and then the tin is made through the reflow soldering process. The paste melts and solidifies, completing the fixed connection to the PCB pad. This process is fast, accurate and highly automated, greatly improving production efficiency and product quality.

Plug-in machine + wave soldering technology: The automatic plug-in machine automatically mounts the Rolling Ball Pogo Pins and accurately inserts the solder pins into the PCB circuit board with printed solder paste, and then melts and fixes the solder paste through the wave soldering process to complete the Fixed connection to PCB pads. The process is fast, accurate and highly automated, greatly improving production efficiency and product quality. This method is particularly suitable for electronic components with extremely long solder legs that cannot be fixed through SMD reflow soldering.

Material & Parts

Rolling Ball Pogo Pins are one of the categories of Pogo Pin Connectors, Vertical Contact type and Side Contact type. This is a built-in spring connector based on a bevel structure design and consists of four core components: Rolling Ball, SolidPin, Spring and Body. Its unique feature is that its contact surface is a gold-plated ball that can rotate 360 degrees, which greatly reduces the wear of the contact surface. Due to its extremely low resistance, its connection is stable and reliable, resulting in long life and durability.

The internal structure of Rolling Ball Pogo Pins adopts a ball + bevel structure, which ensures stable and reliable contact between the ball and the inside of the needle tube.

Contact force and contact resistance are key factors to ensure a stable and reliable connection. There is a close relationship between the two: increasing contact force can effectively reduce contact resistance. Therefore, achieving stable contact force and contact resistance is an important step in establishing a reliable connection.

When working, the lateral force generated by the bevel and the spring is converted into a contact force, so that the gold-plated ball can maintain stable contact with the inner wall of the needle tube. This stable contact force ensures extremely low and stable contact resistance, resulting in a stable and reliable connection.

Vacuum blind hole plating technology is known for its excellent performance and can accurately plate a layer of gold inside and outside extremely fine blind holes. This advanced electroplating process not only ensures the overall beauty of the metal surface, but also provides excellent corrosion and wear resistance. Every detail, whether inside or outside the hole, shows a golden and shiny color, and there will be no peeling or gold falling off problems. The precision and stability of this technology ensure the durability and durability of the electroplated layer, meeting a variety of demanding application requirements.
