pogopin service life,types of electrode

　　The shrapnel microneedle module has the characteristics of high service life. After testing, its average service life is more than 20w times. Under the condition of very good operation, environment and maintenance, it can reach 500,000 times. It has good performance, especially The advantage is obvious in high frequency test. The head of the shrapnel microneedle module has a self-cleaning design, which is maintenance-free and can ensure the long-term stability of the test.

　　The service life of the probe module has been tested at about 5w times. In the case of poor test environment, if dust and other impurities enter the inside of the probe, it will cause damage to the spring. Because the probe itself has no cleaning ability, so The probe must be replaced. This will not only increase the cost for enterprises, but also slow down the test progress and affect the test efficiency.

　　1. In the high current test, the shrapnel microneedle module has always been called "high current shrapnel microneedle module" because it can pass a current of up to 50A. During the conduction process, the current flows in the same material body, and the current transmission is stable. Strong overcurrent capability.

　　The probe module basically has no advantage in high-current testing, and the rated current that can pass is only 1A. Due to the large number of components, the current may attenuate in different parts, resulting in unstable testing.

　　2. In the field of small pitches, the shrapnel microneedle module has a wide range of possible values, which can usually be kept between 0.15mm-0.4mm, which has a stable and reliable solution. The pitch value that the probe module can deal with is between 0.3mm-0.4mm, and the lifespan and stability are poor in small pitches. It can be seen from this that the performance of the shrapnel microneedle module in the small pitch is far better than that of the probe module.

　　3. For the BTB connector male and female test, the shrapnel micro-needle modules use different head types to deal with the BTB male and female sockets, the serrated type contacts the BTB male socket, and the pointed type contacts the BTB female socket, which has better connectivity. To ensure the stability of the test. The test yield is as high as 99.8% (some products can reach 100%) without any puncture marks on the connectors.
