What is a Pogo Pin?

A pogo pin is a spring-loaded electrical connector, which allows consistent and reliable contact. It is made up of three primary parts, a plunger, barrel, and internal spring which ensure stabilized connectivity during vibration or movement.

Pogo pin Manufacturing Process

Material Selection and Preparation

CNCSwissMasion begins with the selection of high quality raw material carefully based on the application requirements. The pin body is usually made of stainless steel or high grade brass to ensure that it is strong and corrosion resistance. Springs are made of phosphor bronze or stainless steel to ensure the same elasticity and contact tips or balls are made of stainless steel or tungsten to offer durability and consistent electrical contact.

Precision CNC Turning of Pin Components

The pogo pin body, plunger, and sleeve are machined using very sophisticated CNC turning, Swiss CNC lathes, and automatic lathes. The machines are fed copper or metal rods and rotated to the specifications of the engineering drawings. The dimensions and tight tolerance are inspected during machining and all parts are deburred to run smoothly.

Dimensional and Visual Inspection

Once turned, the machined parts are checked to specification to ensure that they are of the correct size and tolerance. Microscopic inspection will be done to verify the quality of the surface, concentricity and finish and to verify that every part of the part is of the high quality standards of CNCSwissMasion.

Spring Manufacturing and Heat Treatment

A functional component that is critical is the spring. Precision coiling the wire to the necessary dimensions forms the springs which are then tempered and heat treated. This is done to achieve the right spring force, elasticity and fatigue resistance of long-term use to achieve reliable compression and rebound during repeated use.

Needle and Tube Arrangement

In pogo pin SMT patches, needle tubes are aligned in rows with automated systems. A column frame is filled with needle tubing, machine parameters are adjusted, and vibration is used so that every tube properly fills its respective hole. This measure provides uniform alignment and assembly preparation.

Spring Alignment and Placement

A correct amount of springs is added to a spring column plate. The spring plate and column frame are thoroughly rocked and brought into position so that each spring can fall into place. The correct positioning of springs is a condition of even contact force and consistent electrical operation.

Assembly of Pogo Pin Components

The spring is then inserted into the hollow pin body and the next step is to insert the plunger precisely. CNCSwissMasion provides controlled compression to ensure that the pogo pin is smooth as it extends and compresses without loss of force and jamming.

Contact Tip Attachment

The plunger end is firmly fixed to the contact tip or ball by press-fitting or other controlled means. This guarantees peak contact area, reduced resistance and increased wear resistance through repeated mating cycles.

Surface Finishing and Plating

Pogo pins can be finished in nickel, gold, silver, tin or palladium to improve conductivity, corrosion resistance and life. The entire plating procedures are very controlled to ensure uniformity in depth and bonding.

Comprehensive Testing and Quality Control

All pogo pins manufactured by CNCSwissMasion are rigorously tested, such as spring force test, electrical conductivity test, lifecycle durability test, and environmental test. Only those that have passed performance, reliability, and safety requirements are subjected to final packaging.

Pogo Pin Connector Advantages and Disadvantages

Advantages of Pogo Pins

Long cycle life and high durability, thousands to millions of mating cycles with little performance degradation.
Less wear and tear through spring-loaded wiping motion compared to traditional connectors which use friction.
Low contact resistance, particularly with gold plating, which guarantees the efficient power transfer and signal integrity.
Constant electrical behavior and predictable contact force, even when using high-frequency or power.
Small and space-saving structure, suited to miniaturized and dense electronic assemblies.
Strong shock and vibration durability, consistent contact in mobile, automotive and industrial applications.
Blind-mating capability, which enables tolerance to misalignment and enhance user convenience.
Inexpensive to use in the long term, simplifying assembly, minimizing the number of components and minimizing maintenance.

Disadvantages of Pogo Pins

Cost per pin is larger than with less complex connector types.
Proneness to dust and contamination when not sealed or maintained.
Lateral forces, which may destroy the spring mechanism or shorten life.
Possible wear on mating PCB pads particularly in high cycle applications where pad plating is not done properly.
Small number of pins per connector housing, making very high-density designs more complex.
Higher design complexity, whereby close consideration must be given to the choice of spring force, travel distance, materials, and surface plating to achieve the best performance.
