Factors affecting pogo pin Durability
The pogo pin also has its own lifespan. The pogo pin albums have marked life, but how long the pogo pin needs to be replaced depends on the life of the spring and other related factors that affect the life of the pogo pin. So what are the factors that affect the life of the test pogo pin? Today, the Shenzhen pogo pin manufacturer will take you to find out.
The factors that affect the life of test pogo pin are as follows:
1. Working environment
Conventional pogo pin, this type of pogo pin usually has a life span of about 100,000 times. However, the service life is often determined by the test environment. If the test environment is poor, and various impurities enter the pogo pin inner tube, the spring will be damaged, and the pogo pin must be replaced. This is a small part replacement, and the other is to replace the pogo pin regularly. After a certain period of time is used, 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, so the high-frequency pogo pin replacement is generally to replace the inner core needle, which can greatly reduce the cost.
2. The fineness of the pogo pin
Under normal circumstances, the thinner the pogo pin is, the shorter it is, so the life of the normal pogo pin is close to the theoretical life given by the manufacturer. The jig maintenance is done well, and the cleanliness of the board tested by the jig is high. The test is carried out according to the specified stroke of the pogo pin so that the replacement frequency of the pogo pin is low.
3. How to use a pogo pin
Improper use by the user may also cause the test pogo pin to be damaged and replaced in advance. For example, the depth of pogo pin head depression (that is, the degree of head depression when the head touches the test point. There is a slight contact, there is a head depression two-thirds and depression to the bottom), the speed during the depression, and the depression The strength of the pressing will affect the spring of the pogo pin. Each customer's design and use method are different, and these use methods are several key factors that determine the life of the pogo pin.
In addition, the use of a gold-plated pogo pin on the surface is conducive to conductive enhancement. Generally, manufacturers usually choose SK4 material, which has high-performance springs with an average life span of 30,000 to 1 million times. In fact, many manufacturers do not give a clear idea about the life of pogo pin. The answer is because the pogo pin has many levels. As customers pursue cost calculations, domestically produced materials are divided into common materials and imported good materials, and imported products are also imitations in the domestic market. Regardless of the level of pogo pin, the average manufacturer is afraid to give customers a specific service life.
The above are just examples of the reasons that may affect the life of the pogo pin. There are other reasons that may affect the life of the pogo pin and need to be discovered in practice. Because the pogo pin is very precise, it is recommended to replace it according to the life data given by the manufacturer.
