Use Case of Right Angle Pogo Pin Connector

Studied customer’s requirement

Based on the requirements of the highly precise flashpoint tester and customer, we finalized the 2-pin structure of the right angle pogo pin connector, it was a 4 pieces structure with the ball, which can produce instantaneous high current. so, the connector was made of 2 plungers, 2 barrels, 2 balls, and 1 housing.

The material of the plunger and the barrel was lead-free brass, the material of the spring was SUS304 stainless steel, and the material of the ball was SUS304 stainless steel too. the plating of the plunger was 5U” min over 50-120U” Ni, the plating of the barrel was 3U” min over 50-120U” Ni, the surface of the spring was the insulating layer, and the material of the housing was HTN, so, the designs could meet the targets of 12V & 5A, and the spring force could also be 85gf at the working height of 4.2mm.

What is Its Structure?

The Right Angle pogo pin also consists of a plunger, barrel, and spring. But the barrel is special, it uses a minimal spatial structure while ensuring the connection of electronic components. Barrels are usually right angles.

The barrel is made of a special material, which effectively reduces the size of electronic components. Because the right angle pogo pin has a right angle, it can easily connect electronic components. Because of customers’ different applications, different design concepts are required, including Bias Tail, Back Drilling, Ball, T-pin type, or Coaxial. Of 4 designs, designs of T-pin/Ball/Coaxial can meet the requirement of high current, up to 15A or upper, and its resistance is <30mΩ.



The Electroplating Process

What is The Electroplating Process?

Electroplating is an electrolysis process. The pogo pin material was surface treated to make it more resistant to corrosion and friction. The common surface treatments are nickel-plated gold and tin-plated copper.

The electroplating process of the pogo pin is the same as other electroplating processes, but the operation time of each process is shorter than that of the general electroplating process. Therefore, the electroplating liquid should be adjusted to meet the requirements of the pogo pin electroplating process.



SMT/SMD pogo pin application

The plating of a pogo pin is generally barrel electroplating. It is a kind of electroplating process that which a certain number of pogo pins are placed in a special drum, and the pogo pin surface is attached to various platings in a simple and conducive way under the rolling state.

Advantages of barrel electroplating: it can save small parts mount time. Many small parts must be wrapped with wire because there are no holes to be mounted. These methods are not only inefficient but also difficult to guarantee the electroplating quality. Rotating plating improves electroplating production efficiency and reduces labor costs.

Disadvantages of barrel electroplating: Pogo pins in the drum will collide with each other to produce adverse effects. The space between pogo pins is too small to cause discontinuous electroplating, which is prone to uneven film thickness.  

Electroplating Technology

Steps of Electroplating

Firstly, the degreasing time of the pogo pin is generally 2 ~ 5 seconds, so it needs multi-stage degreasing under high currents.

Secondly, deoxidation cleaning will be carried out after degreasing. Smooth its surface to prevent affecting the thickness of the plating layer.

Finally, the plating time was controlled to control the thickness of the plating layer. The thickness of the plating determines the conductivity and corrosion resistance of the pogo pin. 

Some Common Applications:

  • Cellular phones
  • Laptops
  • Tablets
  • Digital cameras
  • Camcorders
  • Printers
  • Scanners
  • Automotive electronics


Industrial applications:

Pogo Pins are often used in industrial applications where a secure connection is needed. They are commonly used in assembly line testing, product inspection, and quality control. Pogo Pins are also used in a variety of automotive applications, such as engine control modules and infotainment systems. 


Medical applications:

Pogo Pins are also used in a variety of medical applications. They are commonly used in blood pressure monitors, glucose meters, and heart rate monitors. Pogo Pins are also used in many implantable devices, such as pacemakers and defibrillators.
