Probe Connector Features.sewing thimble price

　　In order to maintain the stability of the contact surface impedance, the design of the probe connector should pay attention to maintaining the properties of the gold-plated layer on the contact surface to prevent the influence of external factors such as contamination, diffusion of substrate metal, and contact wear. The electrical performance of the probe connector requires a stable connector impedance. To achieve this, a metal contact interface is required to provide such inherent indiscriminateness. These factors depend on the properties of the coating material and the working process of the connector. Gold has good ductility, durability and wear resistance, so the choice of gold coating material can better improve the mechanical performance of the probe connector. POGO PIN is made of copper alloy, and copper alloy is easily oxidized and vulcanized and corroded in the typical working environment of electrical connectors, so the gold-plated contact surface of the probe connector is used to separate the contact spring from the working environment. In order to achieve the effect of preventing copper alloy from being corroded. Contacting the surface metal is relatively simple for the gold plated layer, which is easily accomplished since it only needs to move when it contacts the surface companion. The establishment of such a contact interface requires that the surface film can be avoided or split during contact and mating. Gold is a metal with strong ductility, so the choice of gold coating material can better improve the stability of the electrical performance of the probe connector. . The mechanical properties of the probe connector are mainly factors such as ductility, durability, wear resistance, and coordination. The probe connector is composed of tiny POGO PINs, so corrosion protection should be considered first.

　　POGO PIN probe connector is a precision connector used in electronic products, which is widely used in semiconductor equipment for connection. POGO PIN probe connector is a spring-type probe formed by riveting and pre-pressing the three basic components of needle, spring and needle tube by precision instruments.

　　The pogo pin probe connector is a precision connector used in electronic products, which is widely used in semiconductor equipment for connection. Pogo pin probe connector is a spring-type probe formed by riveting and pre-pressing the three basic components of needle, spring and needle tube by precision instruments. There are many materials for the needle tube of the pogo pin probe connector, and the material of PB is generally selected. The main reason for the low yield may be due to the increase in impedance during the test of the pogo pin probe connector. The increase in impedance is mostly caused by the wear of the needle during the test, the damage of the coating, and the tinning of the needle. The selection of the spring material of the pogo pin probe connector is also more important, SUS SWP, especially Now there are more and more PB free products, which directly causes the pins or BGA solder balls to become soft or hard. During the testing process, it was found that the original yield was very high. After changing the solder balls or pin materials, the yield rate was extremely poor. , The choice of spring pressure is very important, the test environment is also very strict on the material requirements of the spring, and the high and low temperature test directly affects the working life of the probe. The needle material of pogo pin probe connector is generally selected as Becu or SK. Both have advantages and disadvantages. Becu has good conductivity, but lacks hardness, and SK has high hardness, but it is easy to rust.
