Silicone oil type release film is very common in the production process of circuit boards and electronic and precision electronic components. The surface of the film is coated with a layer of silicone oil type release agent to reduce adhesion and achieve the release effect . It can be divided into single-sided release film and double-sided release film. Today we will share the reasons for the formation of residual silicone oil on the workpiece in the electronic and circuit board manufacturing process and the cleaning method of silicone oil cleaning agent.
So why does residual silicone oil appear on the release film? Firstly, the tension of silicone oil is small and it is easy to leak out of the machine. Secondly, the gas solubility of silicone oil is large, which makes it difficult to carry out effective sealing treatment. At the same time, the thermal expansion coefficient of silicone oil is also relatively large. Overpressure will also cause residual silicone oil. Therefore, we can often encounter that in the manufacturing process of flexible FPC circuit boards, the silicone oil on the release film is transferred to the circuit board, resulting in the need to clean the silicone oil in the subsequent manufacturing process.
Understand the cause of silicone oil residue on the release film, then how to clean the important silicone oil? Generally, in processes such as circuit boards and precision electronic components, it is required to clean the silicone oil without causing damage to the surface of the workpiece or regenerating residual substances. Therefore, the cleaning method of environmentally neutral silicone oil cleaning agent is a very suitable cleaning solution.
Jingchuan Silicone Oil Cleaner is a neutral, environmentally friendly and non-corrosive water-based silicone oil cleaning fluid. Simply mix with water in proportion and use it with ultrasonic to prepare a high suburban formula that meets regulations. It is non-volatile organic matter and easy to biodegrade. . At the same time, the role of silicone oil cleaning agent in the water-based cleaning process can greatly reduce the surface tension of the water, and enhance the penetration and spreading ability of the cleaning agent. In terms of environmental protection, its Ph value is neutral, which is also beneficial to the cleaning of the workpiece. Protection, does not have an adverse effect on the next stage of manufacturing or production process.
