Is the air pressure system of the pcb factory oil-free or micro-oil?

In PCB (printed circuit board) factories, the type of air compressor depends on the specific needs and configuration of the factory. Generally speaking, PCB factories will choose to use oil-free air compressors, mainly because of the high requirements for the purity of compressed air. In the PCB production process, some links require very clean compressed air to avoid oil pollution to the product. Therefore, in these cases, the oil-free air compressor is a more suitable choice.

However, there are certain situations where other types of air compressors may be used. But in general, in order to ensure the air quality and product quality in the production process, oil-free air compressors are more widely used in PCB factories.

To sum up, although the air compressor system of PCB factory can be diverse, considering the production demand, budget, product quality and environmental protection requirements and other factors, oil-free air compressor is usually the first choice.
