Surface Mount Pogo Pins

Production Specifications:

Surface Mount Pogo Pins are a type of electrical connector mechanism that is used in many modern electronic applications and in the electronics testing industry. They are used for their improved durability over other electrical contacts, and the resilience of their electrical connection to mechanical shock and vibration. They are suitable for shielding, grounding, mobile phone antenna, PCB test and other general electrical connection applications.

Surface Mount Pogo Pins work by using a spring-loaded mechanism that allows for a reliable electrical connection between two points. They are used for their improved durability over other electrical contacts, and the resilience of their electrical connection to mechanical shock and vibration. They can be mounted via a cable on the PCB.

Surface Mount Pogo Pins are used in many modern electronic applications and in the electronics testing industry. They are suitable for shielding, grounding, mobile phone antenna, PCB test and other general electrical connection applications. They are also used in surface-mount technology (SMT) which is a method in which electrical components are mounted directly onto the surface of a printed circuit board (PCB).

The installation method

This kind of Surface Mount Pogo Pin is generally stable, and the bottom of the pins tube is designed with a flat bottom, so we can use vertical or horizontal packaging, which also makes it easier to solder to the PCB board. In addition, part of the needle tube has a positioning needle at the tail, so there will be no offset phenomenon, and the effect will be better.

Materials of Pogo pins

The plunger and barrel of pogo pins usually use brass or copper as a base material on which a thin layer of nickel is applied. 

As common in electrical connectors, manufacturers often apply a gold plating that improves the durability and contact resistance.

The springs are usually made of copper alloys or spring steel. And it’s also plated with gold to better performance.

Pogo Pin Connectors Applications  

Spring-loaded connectors are used for a wide variety of applications, in both industrial and consumer electronics.

At present, our products have been successfully used in a wide range of product areas: smart wear, Bluetooth headset, Bluetooth speaker, electronic cigarettes, smart phones, military communications, aerospace electronics, medical equipment, portable electronic products.         

 What structural engineers are looking for is the excellent space saving ability due to the ultra-short and ultra-small size in the design, coupled with the addition and multiplication of electroplating technology; our connector has excellent conductivity, high frequency characteristics and very low conduction impedance. In addition, the design of the spring in the connector ensures stable elasticity and hundreds of thousands of life stability! Based on the excellent performance of pogo pin connector, it is solving the connection technology that traditional spring connector can't solve.      

Electrical Pogo Pins Connector arrangement

When pogo pins are used in a connector, they are usually arranged in a plastic housing, connecting the individual nodes of two electrical circuits. They are commonly found in charging equipment as a connector, facilitating the rapid, reliable connection of the charging electrical devices.

Attentions

When used in the highest-performance applications, pogo pins must be very carefully designed to allow not only high reliability across many mating/unmalting cycles but also the high-fidelity transmission of the electrical signals. The Surface Mount Pogo Pins must be hard yet plated with a substance (such as gold) that provides reliable contact. Within the body of the hook, the plunger must make good electrical contact with the body lest the higher-resistance spring carry the signal (along with the undesirable inductance that the spring represents). The design of pogo pins to be used in matched-impedance circuits is incredibly challenging; to maintain the correct characteristic impedance, the pins are sometimes arranged with one signal-carrying pin surrounded by two, three, or several grounded pins.

 The Surface Mount Pogo Pins are fully preheated, and then when they enter the soldering area, the temperature rises rapidly at a standard heating rate of 2-3°C per second to make the solder paste reach a molten state. Foot wetting, diffusion, flooding, and reflow are mixed to generate metal compounds on the solder interface to form solder joints; after the PCB enters the cooling zone to solidify the solder joints.
