PCB vacuum packaging is to put the printed circuit board (PCB) into a vacuum packaging bag, use a vacuum pump to extract the air in the bag, reduce the pressure in the bag to below atmospheric pressure, and then seal the packaging bag to ensure that the PCB is not damaged during the packaging process. Pollution from the external environment such as oxygen, moisture and dust. Vacuum packaging is very important for PCB protection, especially for some sensitive components and high-precision circuits. It can effectively prevent problems such as oxidation, corrosion and static electricity, and improve the quality and reliability of PCB.
In addition, vacuum packaging can extend the life of the PCB and increase its safety during transportation and storage. When doing PCB vacuum packaging, there are some things to pay attention to. First, you must ensure that the packaging bag is of high quality and can effectively maintain the vacuum state.
Secondly, a desiccant needs to be added to the packaging bag to absorb residual moisture and avoid damage to the PCB. Finally, the vacuum pump needs to be operated carefully to ensure proper extraction of air and sealing of the bag. In short, PCB vacuum packaging is an important protection and preservation measure to ensure that PCB is in the best condition during production, transportation and storage.
