CONFORMAL COATING线路板防护涂料

电路板防护涂料设计用于组装电路板的表面涂覆,固化后在基材表面形成厚度约25-75um的绝缘固体膜层。膜层将电子产品的表面电路、元器件(特别是金属管脚)和外界隔绝。这类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。因而能够帮助提高电子产品的工作稳定性,延长电子产品的使用寿命。而没有任何防护措施的印刷电路板,在这些环境下可能会出现氧化、腐蚀、霉菌生长和短路等问题,导致电路出现故障。

Protective coating for circuit board is designed for surface coating of assembly circuit boards. An insulating solid film with thickness of about 25-75um will be formed on the surface of the substrate after curing. The film will isolate the surface circuit, components (especially metal pins) of electronic products with the outside world. Such applications enable electronic products to effectively prevent the adverse environmental impact of various factors, such as oxidation, moisture, salt mist, dust, mould or corrosive gas, etc. Therefore, it can help to improve the working stability and extend the service life of electronic products. Without any protective measures, problems like oxidation, corrosion, mold growth and short-circuit will occur to the PCB under the above-mentioned circumstances,therefore lead to circuit failure.

随着科学技术的发展电源趋于密集化和小型化,因而对电源的稳定性提出了更高的要求。在电子工业中有些高压电源组件需承受上万伏的高压,且长年处在高温、高湿、高盐雾的严酷环境下,这导致大气中的有害离子加速了对电路板的腐蚀过程。为防止潮湿、霉菌、盐雾对电路的腐蚀,有效避免电流击穿现象的发生,仅仅依靠涂覆三防涂料进行防护,是远远不能满足防护要求的。而使用灌封胶的灌封工艺技术,能够极大地提高电子产品在恶劣环境下工作的可靠性、防护性机抗震性能。在电子工业中,常用的灌封材料有环氧树脂、聚氨酯和有机硅灌封胶。

With the development of the power of science and technology tends to be intensive and miniaturization, and thus the stability of the power put forward higher requirements. In the electronics industry and some high voltage power supply components are exposed to thousands of volts of high pressure and high temperature in the long, high humidity, high salt spray harsh environment, which leads to the atmosphere of harmful ions accelerated the corrosion process of the board. To prevent moisture, mildew, salt spray corrosion on the circuit, effectively prevent the current breakdown phenomenon, relying on three anti-paint coating for protection, it is far from meeting the requirements for protection. Use potting potting technology, can greatly improve the reliability, protective machine seismic performance of electronic products in harsh environments. In the electronics industry, used potting materials epoxy, polyurethane and silicone encapsulants.

针对一些具有更高要求的应用,例如需要产品具备抗震、防水和高绝缘强度等,使用树脂进行浇注密封是一种更佳的解决方案。这方面的资讯可以通过我们的树脂板块获得更多的了解。

For some applications with higher requirements (for example, products are required to have anti-vibration, waterproof and high dielectric strength), using resin for pouring and sealing is a better solution. You can learn more about this through our resin section.
