PCB三防材料设计用于组装电路板的表面涂覆，固化后形成厚度约25-75um的绝缘固体膜层，将电路板上的电路、元器件（特别是金属引脚部位）和外界隔绝。这种应用能使电子产品有效防止环境中各种不利因素的影响，例如：氧化，湿气、盐雾、尘埃、霉菌或腐蚀性化学气体等等，从而能够帮助提高电子产品的工作稳定性和延长使用寿命。

The conformal coating is a thin insulating film of about 25-75um which conforms to the surfaces of assembled circuit boards to isolate the circuitry and components (especially the metal pins) from the ambient environment. It is solid after curing. Such application effectively protects electronic products from various adverse factors in the environment, such as oxidation, moisture, salt spray, dust, mold, corrosive chemical gases, etc. It can, as a result, help improve the stability and working life of electronic products.

随着电子装备的精小化、高集成化、应用环境复杂等因素，电子装备对于高可靠、抗干扰、能适应各种恶劣的工作环境有更多的需求。民用和商用电子产品、航海、航天、汽车、医疗、军事等领域的电子装备广泛采用这种材料和工艺。

With the development of technology, electronic products are getting smaller and more integrated, and their application scenarios are becoming more and more complex as well. Electronic products nowadays post higher demand for reliability, resistance, and adaptability to various harsh working environments. Conforming coating is widely used in civil and commercial electronic products, and electronic equipment for navigation, aerospace, automotive, military, and medical industries.

PCB三防材料按成份或固化方式可以有很多不同的分类，且每一个种类都有其不同的优缺点，或者性能的差异，或者是成本高低等等。因此，不同的用户如何根据自身产品的最终应用场景、要求和设计结构去选择合适的材料至关重要。

Conforming coating can be divided into different categories according to their composition and curing method, each with its own advantages and disadvantages in performance, cost, etc. Therefore, it is vital for a user to choose the right material according to the final application scenario, specific requirements, and the product\'s design structure.

材料的使用步骤和工艺是需要引起重视的环节。我们经常看到一些用户在材料施工前没有对基材进行有效的清洁，或者没有采取有效的固化工艺等等，而这些都会影响到最终的效果。

The process steps and method of material application are also of great importance. We have often seen some users not getting good results because they haven\'t effectively cleaned the substrates before the application or they haven\'t used the right curing method.
