    摘要： A circuit board includes a first circuit board section which is configured to support a set of light emitting diodes, a second circuit board section which is configured to support high-speed electronic circuitry, and a boundary section which defines an EMI boundary between the first circuit board section and the second circuit board section. The boundary section includes a set of outer surface elongated ground strips configured to form an EMI seal onto which a set of EMI shields is capable of mounting. In some arrangements, the set of outer surface elongated ground strips take the form of metallic bands (e.g., layers of copper). Such bands can be integrated into the circuit board itself (e.g., during PCB fabrication), or added onto one or more of the circuit board surfaces (e.g., after PCB fabrication).

    摘要翻译： 电路板包括被配置为支持一组发光二极管的第一电路板部分，被配置为支持高速电子电路的第二电路板部分和限定第一电路之间的EMI边界的边界部分 板部分和第二电路板部分。 边界部分包括一组外表面细长的接地条，其被配置为形成EMI密封件，一组EMI屏蔽件能够安装到该EMI密封件上。 在一些布置中，该组外表面细长接地条带呈金属带（例如铜层）的形式。 这样的带可以集成到电路板本身中（例如，在PCB制造期间），或者被添加到一个或多个电路板表面上（例如，在PCB制造之后）。
