With the development of China's reform and opening up for more than 30 years, China's electronics, information, and communications industries have flourished, laying a solid foundation for China's information technology development and the rapid development of artificial intelligence. The circuit board (PCB) is an important foundation for the development of these industries, and its importance is self-evident. Circuit board manufacturers will face a very practical question: What are the PCB packaging methods ? How to choose the PCB board shipping method to be reasonable? What packaging is used for the circuit board ? Is it heat-shrinkable? Or vacuum packaging? Or vacuum skin protection packaging? Or vacuum tight (close) packaging? Whether the choice of PCB packaging method is reasonable has a significant impact on cost and specific packaging effects. Today, Fengyuan Packaging Information Department will use Fengyuan PCB board packaging for more than 10 years of experience to share with you the specific selection of circuit board packaging methods.

VACUUM SKIN PACKAGING: PCB vacuum body packaging (PCB vacuum protection packaging, tight packaging): 

This packaging method is the most high-end packaging method for circuit boards. After the vacuum packaging film of the circuit board is heated by the PCB surface vacuum protection and close packaging machine, the vacuum suction force is activated under the bubble bottom film. The vacuum packaging film of the circuit board after heating and softening will be formed and attached according to the shape of the circuit board And tightly adhere to the bubble film, so that the circuit board stack is tightly packed and fixed between the upper vacuum film and the lower bubble film. The circuit board is tightly fixed, which can resist friction, oxidation, dust, moisture, and vacuum.

Heat shrink packaging for PCB: HEAT SHRINK PACKAGING:

Heat shrink packaging is to pack a whole stack of circuit boards into a heat shrinkable bag, seal it, and put it in a heat shrinking oven to heat it. The shrink film will be closely attached to the surface of the circuit board. The advantage is that the circuit board can be tightly specified. Disadvantage, the shrink bag must be perforated to complete the shrink packaging, but this will leak air and fail to achieve the vacuum effect.

VACUUM PACKAGING (VACUUM BAG PACKAGING):

The circuit board is put into a vacuum bag, and vacuum-sealed with a vacuum packaging machine to obtain a vacuum package. This circuit board vacuum packaging method has a very high degree of vacuum, and the circuit board is excellent in preventing oxidation. However, there are disadvantages. Because the four corners of the circuit board are sharp, it may cause air leakage. (How to solve this problem? Fengyuan Packaging Information Department will answer it in a later article, so please pay attention to it)

Other packaging methods for circuit boards include tape packaging, kraft packaging, bubble film packaging, etc. However, the appearance and efficacy of these packaging methods are even worse, and they have been gradually phased out.

In summary, the vacuum skin packaging of PCB boards is the most ideal packaging method for circuit board shipments. No matter from the appearance of the packaging of the PCB board, the actual functions have shown excellent results. The above are the valuable conclusions of Fengyuan Packaging Information Department based on more than 10 years of PCB board industry experience. I hope that it will be helpful for the majority of PCB board factories to choose a suitable and reasonable PCB board shipping packaging method.
