电路板平面尺寸和各项机械定位，在PCB设计环境下绘制PCB板面，并按定

The plane size of the circuit board and various mechanical positioning, draw the PCB surface in the PCB design environment, and place the required connectors, buttons/switches, digital tubes, indicator lights, input, output, screw holes, and assembly holes according to the positioning requirements And so on. And fully consider and determine the wiring area and non-wiring area (such as how much area around the screw hole belongs to the non-wiring area).

Board plane size and various mechanical positioning, in the PCB design environment to draw the PCB board surface, and according to positioning requirements to place the required plug-ins, keys / switches, digital tubes, indicators, inputs, outputs, screw holes, assembly holes and so on. And fully consider and determine the wiring area and non-wiring area (e.g. how much range around the screw hole belongs to the non-wiring area).

The plane size and mechanical positioning of the circuit board, draw the PCB surface in the PCB design environment, and place the required connectors, keys / switches, nixie tubes, indicator lights, input, output, screw holes, assembly holes, etc. according to the positioning requirements, fully consider and determine the wiring area and non wiring area (such as how much range around the screw hole belongs to the non wiring area).<br>
