    Abstract: Electrical components may be mounted on a printed circuit or other substrate. The electrical components may be covered with a conformal coating containing a wavelength-tuned-light-absorption-enhancement additive. The additive may be a dye or other additive that creates a light absorption peak at a given wavelength. To form openings in the conformal coating in alignment with the electrical components without damaging the components, a laser ablation tool may apply laser light at the given wavelength to the conformal coating. Openings may also be formed by placing tape over the components before the con form at coating is applied. The tape may have a color with a light absorption peak at the given wavelength to facilitate the formation of openings without damaging sensitive components.

    Abstract translation: 电气部件可以安装在印刷电路或其它基板上。 电气部件可以用包含波长调谐光吸收增强添加剂的保形涂层覆盖。 添加剂可以是在给定波长处产生光吸收峰的染料或其它添加剂。 为了在保形涂层中形成与电气部件对准的开口而不损坏部件,激光烧蚀工具可以将给定波长的激光施加到保形涂层。 开口也可以通过在施加涂层之前将带放置在构件上而形成。 带可以具有在给定波长处具有光吸收峰的颜色,以便于形成开口而不损坏敏感组件。
