Factors affecting the life of Pogo pin connectors
1, test environment
Conventional spring thimble, in general, the life of this kind of spring thimble is about 100,000 times. However, the service life often depends on the test environment. If the test environment is poor and various impurities enter the inner tube of the spring thimble, the spring will be damaged, so the spring thimble must be replaced. This is a small part replacement, and the other is to replace the spring thimble regularly. After a period of use, the spring thimble must be replaced. If it is a high-frequency spring thimble, it is more special. The high-frequency spring thimble is mainly the inner core needle of the high-frequency needle. Therefore, the high-frequency spring thimble is usually replaced by the inner core needle, which can greatly reduce the cost.
2, the fineness of the spring thimble
Under normal circumstances, the thinner the spring thimble will be shorter, so the life of the normal spring thimble is close to the theoretical life given by the manufacturer. Do a good job in the maintenance of the fixture, and the cleanliness of the board for the fixture test is high. Test according to the required stroke of the spring thimble, so that the frequency of replacement of the spring thimble will be very low.
3. How to use spring thimble users
Improper use by the user may also cause the test spring thimble to be replaced in advance due to damage. For example, the depth of the head depression of the spring thimble (that is, the degree of head depression when the head touches the test point. There is a slight contact, including the head depression two-thirds and the depression to the bottom), the speed during the depression, and The force when pressing down will consume the spring of the spring thimble. Each customer's design and use method are different, these use methods are the key factors that determine the life of the spring thimble.
In addition, the choice of gold-plated on the outer surface of the spring thimble is conducive to enhancing conductivity. Manufacturers generally choose SK4 material, which contains high-performance springs with an average life span of 30,000 to 1 million times. In fact, many manufacturers cannot give the life of the spring thimble. For a clear answer, there are many levels of spring thimble. With the cost budget requirements of customers, domestic products are divided into common materials and imported good materials, and imported products also have many imitations in the domestic market. Regardless of the level of spring thimble, manufacturers are afraid to give customers a specific service life.
