The development of spring test probes follows the trend of the times. With the increasing use of our electronic products, cell phones, computers, cameras, smart robots and so on, the requirements for connectors are getting higher and higher. Not only to be compact, but also requires precision and perfection. Only the production of connectors to adapt to the demand to get better development. Spring test pin future development potential and prospects are expected. Although the spring test pin is not the main character of the device, but it is an important supporting role. IC is like the heart of the device, the spring test pin is the hands and feet of the device, the hands and feet are exceptionally important for the complete function of the device.

Spring test probes are usually used in the battery connection of our smart devices as well as in antenna transmission, playing the role of conduction transmission. The advantages of spring test probes are as follows:

1.Spring-loaded test pins for better transmission of antenna's high-frequency signals

Compared with other connectors, spring-loaded test pins have a smaller distributed capacitance and distributed inductance than other connectors due to a shorter current path at the same working height, which is more favorable for impedance matching, especially in the high-frequency band. Based on the same working height, spring-loaded test pins have a much higher self-resonance frequency band than shrapnel, which results in lower losses and facilitates the efficient transmission of high-frequency signals. Spring test pins in the metal frame design can be more flexible signal transmission, so that the antenna radiation is more far away from the motherboard and its components, more conducive to the performance of the antenna, at the same time spring test pins in the contact and assembly program is also more flexible in the metal battery cover, metal frame, ultra-thin model design has a better use of space, so in the transmission of signals spring test pins relative to other connectors have more advantages. Advantage in signal transmission.

2.Spring-loaded test pins enable high-current connection solutions

Spring-loaded test needles are not only gold-plated to withstand the passage of high currents; at specific currents, its spring is also required to be gold-plated; in order to better carry the passage of high currents to ensure the stability of the current, however, this is the antenna shrapnel can not be done.

3.Spring-loaded test pins make it easier to achieve watertight structures

4.Spring-loaded test pins provide precise and stable connection points for RF signal transmission.

When spring-loaded test pin connectors are used in antenna connectors, a more stable connection point results in more stable RF performance without frequency shifts.

5.Spring-loaded test pins take up less space and are more stable than other connectors.

Spring test pins have a greater amount of compression than connectors of the same size, as well as a more stable contact with a relatively small change in spring pressure when subjected to a strong impact from an external force.

6.Spring test pins do not require stamping molds, short sample development and mass production time.

So now most of the connecting devices for cell phones are spring test pin connectors, because spring test pins are more in line with the concept of connecting electronic devices nowadays.
