1. Do not use a brush to tidy up

Most brushes are made up of animal hair, and during the brushing process, static electricity induction is inevitable due to friction with each other. Some small components on PCB boards are easily disturbed and may even break down, resulting in more severe consequences; In addition, when the brush is used for tidying up, some hair may be left behind, which can cause unnecessary trouble for the transmission of the PCB circuit board. Therefore, avoid using a brush to clean up dust.

2. Avoid blowing balloons

Most friends believe that using a balloon to blow is an ideal method, which is still useful for some relatively dry PCB circuit boards, but not effective for damp PCB circuit boards. Due to moisture, dust often adheres firmly to the PCB circuit board and cannot be blown off at all. In other words, even if it can be blown away, dust particles may still be blown between the pins of the components and stuck there tightly. For large-scale integrated circuits, the pins are denser, and this situation is even more severe. So, it is important to avoid using balloons to deal with dust issues.

3. Avoid quietly tapping with your hands

For the dust on the surface of PCB circuit boards, many people choose to turn it over and quietly tap it with their hands. In fact, doing so not only relieves the dust, but also makes it easier to loosen the connection of various PCB circuit board components. Due to the extremely precise soldering of PCB circuit boards, even a slight lack of attention can result in serious consequences.

2、 Three requirements for PCB circuit board cleaning

1. Try to avoid dusty areas as much as possible

To deal with the dust problem of PCB circuit boards, we need to start from the source and reduce their use in dusty environments. For example, squares, stairs, windows, etc.

2. Choose a professional cleaning department

3. Regularly check the PCB circuit board

The dust on PCB boards is accumulated over time. By cultivating good habits of use and maintenance, dealing with PCB board dust problems will no longer be so difficult.
