In this instructable they will going to show you how to make your own printed circuit board business card
A computer with the PCB design software CadSoft Eagle installed is all you will need.
Download the program for your operating system(Linux, Windows or Mac). When you run the program for the first time, choose the “Run as freeware option.” You can use this as long as you do not sell any of your boards. You are just fine making business cards and small circuit boards for yourself. There are some limitations to using the Freeware version of Eagle. The useable board area is limited to 100 x 80 mm (4 x 3.2 inches), only two signal layers can be used (Top and Bottom), and the schematic editor can only create one sheet.
To add you name and details, right click the plus sign at the upper left hand of the text and click on properties. Customize the board as much as you want. They added a silkscreened logo to the back of board in the same location at the contact information. To do this, you will need to learn a bit about layers. Layer 21(tPlace) and layer 22(bPlace) are used for silkscreening the top and bottom of the board respectively. Create your logo and flip it horizontally and save it as a bitmap(.bmp). In Eagle, go to File->Import->Bitmap and import your logo to layer 22. If you want to change the shape of the board, you can edit layer 20(Dimnsion) with the Polygon tool in the tool bar.
Order Your Circuit Board Business Cards
Once you are satisfied with your board, it’s time to order. There are a ton of board houses to choose from, but my favorite for small runs like this is Dirty PCBs. They aren’t dirty at all. You get around 10 PCBs for $14! You might get 8 or you might get 15. For this business card, the Protopack will be $25 because the board fits into the 10cm x 10cm category. Either way, the price is great! Another good thing about DirtyPCBs is all you need to do to order is upload your .brd file and pick a few options. Most board houses will require you to send them gerber files, but they create the gerber files themselves. Now you can choose the board color(Red, Yellow, Green, White, Black), your board thickness and what coating you want. HASL is just fine and it’s free. You will not need a stencil for this project because there are not surface mount pads on the boards.
