The pogo pin also has its own lifespan. The pogo pin album will mark its lifespan, but the pogo pin needs to be replaced for how long it is used. This is mainly determined by the life of the spring and other related factors that affect the life of the tested pogo pin. So what are the factors that affect the life of the test pogo pin? Let’s take a look with Wan Chang’s editor.
1. Test environment
Conventional pogo pin, this kind of pogo pin generally has a life span of about 100,000 times. But the life is often dependent on the test environment. If the test environment is poor and various impurities enter the pogo pin inner tube, the spring will be damaged, so the pogo pin must be replaced. This is a small replacement, and the other is to replace the pogo pin regularly. After a certain period of time, the pogo pin must be replaced. If it is a high-frequency pogo pin, this is more special. The high-frequency pogo pin is mainly the inner core needle of the high-frequency needle. Therefore, the replacement of the high-frequency pogo pin is usually to replace the inner core needle, which can greatly reduce the cost.
2. The fineness of the pogo pin
Under normal circumstances, the thinner pogo pin will be shorter, so the life of the normal pogo pin is close to the theoretical life given by the manufacturer. In view of the good maintenance of the fixture, and the high cleanliness of the board for the fixture test, the test is performed according to the specified stroke of the pogo pin, so that the frequency of replacement of the pogo pin becomes low.
3. How to use pogo pin users
If the user does not use it properly, it may also cause the test pogo pin to be replaced in advance due to damage. For example, the depth of pogo pin head depression (that is, the degree of head depression when the head touches the test point. There will be slight contact, including head depression two-thirds and depression to the bottom), the speed during depression, and The strength of pressing down will cause damage to the spring of the pogo pin. Each customer's design and use method are different, these use methods are the key factors that determine the life of the pogo pin.
In addition, the use of gold-plated pogo pin surface is beneficial to enhance conductivity. Ordinary manufacturers generally choose SK4 material, which has a high-performance spring with an average life span of 30,000 to 1 million times. In fact, many manufacturers will not give the life of pogo pin. A clear answer is given because there are many levels of pogo pin points. As customers pursue cost calculations, domestic products will also be divided into common materials and imported good materials, and imported products will also have many imitations in the domestic market. No matter which level of pogo pin it is, ordinary manufacturers are afraid to give customers a specific service life.
