| 释义 | PC board technology 印制电路板工艺 Technology that follows many of the photolithographic procedures used to make hybrid circuits,passive resistor networks, and even integrated circuitry. The track like metallic wiring paths are laid down on thin insulating boards, typically epoxyimpregnated glassfiber. Anumber of different methods employing a variety of chemical and mechanical processing steps are involved. Regardless of procedures, three basic steps are common to all printed circuit technology; design, photography,and manufacturing. 一种仿效用来制造混合电路、无源电阻网络以及集成电路的光刻技术。 将细的金属线布放在很薄的绝缘板上,典型的绝缘板是充填了环氧树脂 的玻璃纤维板。这种技术包括了应用于各种化学与机械工艺步骤中的大量不同的方法,不管 其工艺如何,对于所用印制线路技术而言,三个基本步骤是共同的,即设计、光刻和制造。 |
