Spring-loaded Connectivity Pogo Pins

Spring-loaded connectivity Pogo pins

In order to ensure 100% contact between the plunger pins and the needle barrel when working, we cut the end of the needle in contact with the spring into a bevel. This design concept can ensure a low and stable contact impedance, and can absolutely ensure the stable conduction of the product.

The 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 is different for different use occasions, but the nickel layer needs to be greater than 60uin, and the gold plating greater than 4uin.

The 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 is 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.

The gold-plated Pogo pin of good quality is 10～20u”, but most products of other brands are 1～5u”, which is very different. 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. It all depends on the customer's product positioning and the corresponding market.

It looks like a simple part, but if there is no good quality control and perfect manufacturing process level, it is very prone to power failure and pin stuck, or the durability (lifetime) is too short. The process is extremely delicate and complicated, and every process from lathe processing, electroplating, and assembly must be strictly controlled.
