Causes of poor potentiometer contact2021
What are the problems caused by poor potentiometer contact? What are the reasons for poor potentiometer contact? Let's take a look at the source of these problems?

Poor contact of the potentiometer will cause a lot of undesirable problems, such as potentiometer noise, out of sync, no sound, loud and small sound, etc. These are the biggest headaches for customers, and they are also the biggest headache for us as a potentiometer manufacturer. Because the poor contact of the potentiometer is a big problem, it is also a problem that is easy to repeat.
The so-called poor contact of the potentiometer refers to the insufficient contact between the brush of the potentiometer and the carbon diaphragm of the potentiometer. Then the key point to solve the problem is to make the brush contact with the carbon diaphragm.
1. When the potentiometer brush is closed, all must be checked. The content of the check: Is the brush rusty? Is there any deformation? Is there any deformation after the brush is closed?
2. Check whether the carbon film track of the carbon film is broken or has bumps.
3. After the potentiometer is assembled, check the feel, and then use the noise machine (our professional test potentiometer noise machine, Japanese product).
