The pogo pin is widely used in semiconductor connectors and is one of the important components of the connector. Its main function is to conduct electricity and transmit information. The advantages of the pogo pin are that the creation rate is fast, the production cost is low, and no mold opening is required. The composition of the shrapnel penetrator is often Terminals, plastic cores, iron shells, the cost of mold opening is 100,000 RMB, the development cycle often takes 2-4 months, and the price is usually 0.3-1.0. The price of the spring thimble is 0.30.8. Free samples are available. Quantity It only takes 7 days to produce. Do you know what are the characteristics of the spring thimble?
1. Low voltage contact resistance
The pogo pin contact resistance of the contact system is evaluated under the condition that the supply voltage and current do not change the size of the physical contact surface and the oxides and films on the contact surface. The maximum test current is 100mA and the maximum open circuit voltage is 20mV.
2. Insulation resistance
Detects the resistance of insulating substances when a DC potential is applied between adjacent contacts or between the metals closest to the contacts
3, pressure resistance
The voltage that the pogo pin connector can withstand in the event of a sudden increase in system voltage or transient overpotential due to switching
4, positive force
In the normal use of the contact system, the contact point is subjected to pressure perpendicular to the contact surface.
5. Durability
Due to the wear of the contact surface of the spring thimble during insertion and extraction, the wear will reduce the mechanical and electrical performance of the connector. Under the set environment, the insertion and extraction of the connector is a cycle, and the minimum number of insertion and extraction cycles that the connector can withstand is evaluated. Connector Durability
6. Vibration
Evaluating the effect of small changes in the contact surface of a pogo pin due to mechanical force on the dimensions of the electrical characteristics of the contact system
7. Mechanical shock
Mechanical and electrical integrity of pogo pins, shocks that may be encountered during handling, transportation, etc., when the connector assembly acts on electronic equipment
8. Thermal shock
Sense resistance when pogo pins are exposed to extremely high and low temperatures, or worst-case shocks during storage, transportation, and use.
9, Temperature life (
Evaluate the effect of that environment on electrical stability when exposed to a high temperature environment where mechanical properties fail due to temperature changes. High temperatures can cause oxidation of the contacts, reducing the normal force of the terminals, resulting in degraded electrical performance.
10. Humidity Thermal Cycling
Evaluate the effect of the environment on the electrical stability of the contact system when exposed to a high temperature\/high humidity environment that can cause mechanical failure. These effects include accelerated oxidation by moisture at the contact surfaces, oxidation of fine particles between the contact surfaces and oxidation of the underlying metal.
