A printed circuit board (PCB) is a mechanical base used to hold and connect the components of an electric circuit. PCBs are used in nearly all modern consumer electronic devices and accessories, including phones, tablets, smartwatches, wireless chargers, and power supplies These multi-material, ...
To design a Printed Circuit Board (PCB), you need to draw holes, pads, and wires for your circuit. When you’re done drawing the board, you can either send the design to a manufacturer that will make it for you (it’s actually pretty cheap) – or you can etch it yourself at home...

解析 印制电路板的英文全称为Printed Circuit Board; 印制电路板的英文简写为PCB; 印制电路板指在绝缘基材上,按预定设计,制成印制线路、印制元件或由两者结合而成的图形。; PCB制造的基本工艺流程一般都要经历:胶片制版、图形转移、化学蚀刻、过孔和铜箔处理、助焊和阻焊处理等过程。
A printed circuit board (PCB) is an electronic circuit used in devices to provide mechanical support and a pathway to its electronic components. It is made by combining different sheets of non-conductive material, such as fiberglass or plastic, that easily holds copper circuitry. ...
