As a basic electronic component, pogo pins have been widely used in watches and mobile phones with the development of the communication industry.
That said, if you intend to use pogo pin on your product, it’s important that you get to know how it’s manufactured and what you need to pay extra attention to in its manufacturing process.
Look no further, this article will offer you some tips.
1. What is a pogo pin?
A Pogo pin is a device used in electronics to establish a connection between printed circuit boards.
Pogo pins are usually arranged in a dense array, connecting together many individual nodes of the two circuit boards.
According to different needs, there are various pogo pin products, such as flat bottom type, plug-in type, wire-bonding type, bent double head type and thread type on market.
2. Product requirements that should be met
When used in the highest-performance applications, pogo pins must be very carefully designed to allow not only high reliability across many mating/ unmating cycles, but also high-fidelity transmission of the electrical signals.
The pins themselves must be hard, yet plated with a substance that provides for reliable contact.
3. Structure required
Plunger + Spring + Tube = Pin
A Pogo Pin takes the form of a slender cylindrical receptacle containing a sharp, spring-loaded pin.
Pressed between two electronic circuits, the sharp points at each end of the pogo pin make secure contacts with the two circuits and thereby connect them together.
The bottom of the plunger is usually a beveled structure, whose function is to ensure that the pogo pin keeps plunger in contact with the inner wall of tube during operation, allowing electric current to pass through plunger and tube to ensure stability and low impedance of pogo pin.
4. Materials required
The core of a pogo pin is definitely the pin.
To form high contact strength, low contact resistance and maintain performance in thousands of plugs and strips, a beryllium copper material with special tensile annealing properties is required.
The thickness and shape of beryllium copper ensure long life and long-term performance of pins. In most situations, pins are plated with gold to ensure reliable contact.
Electroplating gold can reduce the contact resistance and keep electrical conductivity excellent. As a result, the pogo pin product is easy to weld with strong corrosion resistance and wear resistance.
5. Future development trend
In the actual manufacturing process of technology products, there are diversified requirements for the size and quality of pogo pins. Various connectors composed of different pins have certain development potential.
5. 1 Nano-level interconnector
Nanoscale interconnects are required because analog circuits are replaced by digital circuits, electronic devices are moving from wired connections to wireless connections, and the overall device design is shifting from desktop to portable.
The nano pogo pin connector has been largely applied in military and aerospace fields (Unmanned spacecraft, communications satellites, space shuttle navigation etc.).
In addition, it has worked out in medical and petroleum industries (magnetic resonance coils, digital stethoscopes) as well as portable and remote control products.
5. 2 Fiber spring pin connector
The extremely thinning demand of mobile phones is becoming more and more urgent for the ultra lower back of the internal fiber spring pin connectors, especially in the fields of Wearable devices, children’s smart bracelets, smart watches, wearable phones, Bluetooth headsets, data lines and charging lines.
In order to achieve low profile, narrow pitch, multi-polarization and high reliability, many manufacturers have been using analog technology for in-depth research and development.
