选择适用于印制电路板的“绿色”敷形涂覆

Selecting a "Green" Conformal Coating for Printed Circuit Board

敷形涂覆的处理方法在近年来得到了迅速的发展,它不仅应用在要求非常高的场合之中,例如:航空电子设备、军用电子产品和汽车中,同样也应用于便携式产品之中。现如今许多印制电路板通过采用防护措施获得益处,然而,通过在有关环境方面"绿色"的敷形涂覆处理可以让它们更可靠的工作,甚至在恶劣的环境之下也是如此。每种类形的敷形涂覆都有其自身的优点和不足,选择考虑时必须综合最佳的性能、经济性和环境友好型。

The usage of conformal coatings has been rapidly expanding in recent years, not only in highly demanding applications such as avionics, military and automotive, but also in portable electronics. Many of today＇ s circuit boards benefit from the use of protective, yet environmentally ＂green＂ conformal coatings that allow them to operate reliably, even in harsh environments. Each type of conformal coating has its own set of benefits and detractors that must be considered to make the best performance, economic and environmental choices.
