1.0 overview

This specification defines the general performance parameters and test requirements of Pogo pin series products.

2.0 Requirements:

2.1 Dimensions

The external dimensions meet the requirements of the product drawings.

2.2 Materials and plating

Body is a brass alloy, and the nickel-plated surface is covered with a gold-plated layer. The thickness of the nickel layer and the gold-plated layer are different for different use occasions, but the nickel layer needs to be greater than 60uin, and the gold plating greater than 4uin.

Plunger is a brass alloy. The nickel-plated surface is covered with a gold-plated layer. The thickness of the nickel layer and the gold-plated layer are different for different applications. However, the nickel layer must be greater than 60uin and the gold plating greater than 16uin.

Spring is stainless steel, or it can be electroplated piano steel wire.

The plastic is high temperature nylon plus 30% glass fiber.

Project details

The literal translation of Pogo in English means Seesaw, and Pin is usually a small object like a pointer. Pogo pin is a small elastic pin with a spring, referred to as a pogo pin.

    Hewlett-Packard designed the first pogo pin more than 20 years ago and registered a trademark. It is used in the HP-designed printer to make the signal connection between the board and the board, which reduces the trouble of cable connection, makes the connection easier, and also makes the connection easier. The internal circuit is cleaner and fresher.

     Pogo Pin looks like a simple part, but without a good quality control and perfect manufacturing process level, it is very prone to power failure and pin stuck, or short durability (lifetime). The process is extremely delicate and complicated, and every process from lathe processing, electroplating, and assembly may bring serious hidden dangers.

     For Pogo pin lathe processing, it is recommended to use Japanese core automatic lathe processing, so that the precision of the parts can be guaranteed within +/-0.01mm, but most factories use cutting machines for processing, and the accuracy is completely impossible to guarantee. Second, the surface finish processed by the lathe, especially the inner surface finish of the needle tube is very critical. Most factories do not have surface roughness testing equipment and do not supervise this important parameter atall.

     In terms of Pogo pin electroplating process, the thickness of the coating has a huge impact on the cost structure. The high-quality gold plating is 16-20u", but most other brands are 1-2u", which is a big gap. Secondly, the quality of the gold plating in the hole also has a great influence on the electrical properties (dynamic impedance) and mechanical properties of the product.

     The process of Pogo pin assembly is also important. Poor assembly process can cause serious problems such as skew of the needle, excessive needle height difference, pin stuck, peeling of the nozzle, etc.

Pogo pin is a kind of precision connector used in mobile phones and other electronic products. It is widely used in semiconductor equipment for connection.

    There are different appearances according to different applications, but as a whole, there is a precision spring structure inside the pogo pin. The surface of the product is generally gold-plated, and the unit price of the product is generally about 5 to 1 yuan.

The thimble realizes energization or conduction, and most of it contacts the copper wall through the oblique bottom, and the spring bears a small amount, so the inner wall of the copper sleeve is required to be smooth. For example, if the POGOPIN factory has a non-beveled surface, but a flat bottom, most of the current will be conducted through the spring, and the requirements for the spring will be very high. Of course, it is necessary to ensure that the power failure occurs when the current suddenly increases.


    Pogo pin is a spring-type probe formed by the three basic parts of needle, spring and needle tube after riveting and preloading by precision instruments. There is a precision spring structure inside. The surface coating of pogo pin is generally gold-plated, which can better improve its anti-corrosion function, mechanical performance, electrical performance, etc. Pogo pins are generally used for precision connections in electronic products such as mobile phones, communications, automobiles, medical, aerospace, etc., which can improve the corrosion resistance, stability, and durability of these connectors. Since the pogo pin is a very fine probe, it can be used in precision connectors to reduce the weight of the connector and the volume of the appearance, which can make the connector more refined and beautiful
