Comparison of shrapnel microneedle module and pogopin probe module.gene probe price

　　1. Current transmission capability and adaptability in small pitch fields

　　The shrapnel microneedle module is a one-piece shrapnel structure with a light and thin body. After being plated with gold, it is hardened and can carry a current of up to 50A. It flows in the same material during current transmission and has a better connection function; In the field of pitch, the shrapnel microneedle module has high adaptability, the smallest value range can reach 0.15mm, and the performance is very stable.

　　The Pogopin probe module is composed of a needle, a needle tube, and a needle tail. Due to the large number of components, the current is transmitted from the needle to the needle tube and then to the needle tail. The resistance is usually variable, and the current will attenuate in different parts, resulting in failure of connection. Stable situation; in the field of small pitches, pogopin has poor adaptability, and the available value range is only between 0.3mm-0.4mm. There may be pin stuck or broken needles, and it cannot cope with smaller pitch tests.

　　2. High frequency test and service life

　　The average service life of the shrapnel microneedle module can reach more than 20w times, and it can reach 50w times under the condition of good operation, maintenance and environment. It has a long service life and does not need to be replaced frequently. In the high-frequency test, it has a better response ability and can maintain a stable connection.

　　The service life of the Pogopin probe module is only about 5w times. In the face of high-frequency test requirements, it needs to be replaced and cleaned frequently. The cost of time and material resources will slow down the test progress, which is not conducive to the stability of the test. .
