Some people have been asking me what the specific material of the pogo Pin is, and now I am writing an article specifically to explain it. I hope you can be more clear in this way.
Of course, the specific processing technology and production process are not that simple. It is still a very technical matter. However, the application field of pogo is very wide. Now there are more and more structural engineers and scheme designs. Companies like to think about this kind of precision hardware components that are composed of springs, needles, and needle tubes when they design projects.
| Materials and plating for Spring Pogo pins | |||
| plunger | Material | BeCu | Most used material for spring probe for semiconductor. |
| Material | Pd Alloy | Effective for anti-solder migration. No plating is needed. | |
| Plating | Au Alloy | Hardness is higher than Au(Gold) plating and effective for anti-solder migration. | |
| Plating | Au(Gold) | Good electric conductivity. | |
| Barrel | Material | Copper | Brass, Phosphor Bronze, Nickel Silver, BeCu |
| Material | Alloy | Barrel developed by ZZTKJ. Outer diameter is available from 0.11 to 0.42mm | |
| Plating | Au(Gold) | Good electric conductivity. | |
| Spring | ― | Spring Steel Wire (SWP)（Music Wire） | Operating temperature: -45~125℃ |
| ― | Stainless Steel Wire (SUS) | Operating temperature: -45~140℃ | |
| ― | Stainless Steel Wire for high temperature | Operating temperature: -45~200℃, developed by KITA. |
More and more product structure engineers are gradually getting to know and understand it. In many high-end product fields, Pogo Pin Connectors are rapidly swallowing and replacing the traditional shrapnel-type connector market, gradually becoming the mainstream of technology! The well-known Apple Inc. has used Pogo Pin Connectors on all series of Mac-Book to realize transmission and conduction, including power supply, data transmission, and signal transmission.
