After survey  we( www.pcbway.com/b ) found that so many of our clients are electronic enthusiasts. They are interested in Arduino, Raspberry Pi, microcontroller or others. In order to support them to make more interesting projects, we deliberately produce some modules as gifts for engineers. This time the gift module is “ 2 channel Relay Module ”. Each time we will choose 2-4 lucky engineers. How to get it?( you can choose any one ) 1.@ our official Facebook that you want to be the lucky engineer. 2.@ our official Twitter that you want to be the lucky engineer. 3.@ our official Instagram account that you want to be the lucky engineer 4.Leave the comment below the post 5.Share the activity in your blog or any other website you like Note: 1.When you are notified that you are the lucky engineer, please login in our website timely and fill in your detailed address information. 2.The module will be shipped by HongKong post. 3.To make yourself contacted, ple

Step1: The work before generate the Gerber file  Before generate Gerber file, you need to set criteria, but for most of PCB designers, these are not necessarily. The following is a brief explanation of these settings, You can also ignore these setting when generate Gerber file.  1. The settings of PCB shape and size, generally are mechanic1,2 layers. 2. Before generate the Gerber file, the preprocessed of PCB file. The preprocessed include: a. Add break away rails of PCB b. Add stamp hole. c. Add the machine jack. d. Add mouting hole e. Add drilling descript_ion. f. Add dimension descript_ion. g. Set the origin Step2: Generate Gerber file 1. Open the Gerber Files.
