Process trilogy PCB products

PCB is manufactured through a series of complicated processes of a printed circuit board (Printed Circuit Board), after making, the engineer can then be placed above the various electronic components, and a circuit board via a wire or even line to achieve electrical connection between the respective components. A complete PCB products flow into three steps shown above: 1.PCB Design: EDA engineer with a suitable tool, the combination of reasonable electronic component and a circuit schematic design PCB, and then use these tools to generate Gerber files for manufacturers for manufacturing a circuit board PCB. 2.PCB Manufacturing: PCB manufacturers to produce a printed circuit board according to Gerber file processing. 3.PCB Assembly: The component is mounted on the printing plate, welding and debugging, wherein PCBA production can also be achieved directly by the manufacturer.
Personal engineer responsible for the first step, PCB design, PCB design tool that is use to design the circuit, draw schematics, PCB layout of the wiring, and ultimately generate Gerber design files. But engineers also need to have some understanding of the two-step behind, so good cost control, easy assembly and commissioning of the board after the hand.

PCB design
common design tool

Altium Designer - 国内外最常用的PCB设计工具，protel的继任者。

Eagle - 目前归属于Autodesk，其收费模式比较特别，是按照不同的档次按月收费，费用并不高。对于初学者来讲可以用其功能受限的免费版本。对于高校用户如果能提供高高校的邮箱可以使用其全功能软件，三年免费。Eagle在开源、创客届比较受欢迎，因此如Adafruit、Sparkfun都有针对Eagle格式的库文件以及原理图文件提供

Allegro - Cadence

DesignSpark - RS     Components

pads - Mentor

OrCAD - Cadence

proteus - Labcenter Electronics Ltd

ADS - Keysight

Free PCB design tools:

KiCad - 开源、免费、支持Windows、Linux、Mac OS，是个功能比较强大、比较成熟的软件，其库资源也比较丰富。

Upverter - 隶属于Altium公司的免费工具，但只支持Window操作系统

CircuitMaker - Upverter
