  Comparison of shrapnel microneedle module and pogopin probe module

  1. Current transmission capacity and adaptability in small pitch fields

  The shrapnel microneedle module is a one-piece shrapnel structure with a light and thin body. After being gold-plated, it is hardened and can carry a current of up to 50A. It flows in the same material during current transmission, which has a better connection function; In the field of pitch, the shrapnel microneedle module has high adaptability, the smallest possible 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, causing the connection failure. Stable conditions; in the field of small pitches, pogopin has poor adaptability, and the range of possible values is only 0.3mm-0.4mm. There may be pin stuck, 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 good operation, maintenance, and environment. It has a long service life and does not need to be replaced frequently. In high-frequency tests, it has a good 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 time and material cost will slow down the test progress, which is not conducive to the stability of the test. .

  3. The fit of the head shape and the object to be tested

  When testing connector modules such as mobile phone batteries, screens, cameras, etc., the shrapnel micro-needle module can be used with different head types to deal with the male and female connector sockets, making the connection more stable. When testing the male seat, the zigzag shrapnel can be used to contact the top shrapnel of the connector male seat at multiple points to ensure the stability of the contact; when testing the female seat, the pointed shrapnel can be used to keep the two sides of the shrapnel of the connector female seat in contact at all times to ensure The stability of the connection. The test yield of the shrapnel microneedle module on the female seat can reach 99.8%.
