Elecrow prepared this Chrismas tree free. Please have a look at the following picture. You can get it via order it online. The method to design such shape PCB with eagle is very easy and you can design PCB with other special shape. The following steps shows how to design this PCB via eagle.

First, prepare the picture for the shape, silk screen and solder mask layer. The following picture is some pictures that we prepared before importing them to the eagle design file. The left top two pictures is original picture and the other pictures is proceeded to BMP file.You can change the size of the pictures before importing to the eagle design file.

Second, Importing the BMP pictures to check the size of picture and then to adjust the size of the picture.

Step 1, NEW a .brd file.
Step 2, Right click the ulp button and select the import-bmp.ulp.

Step 3, select the BMP picture you need to import and press the open button.

Step 4, Select used colors. If you need to import the black color, select the black color, If you need to use the white color, selet the white color.

Step 5, select one layer and press the ok button. The step is very important.

The following layer is what we used mostly.

1 – TOP   (top copper layer)
2 – Bottom  ( Bottom copper layer)
21 – tPlace  (top silk screen)
22 – bPlace  (Bottom silk screen)
29 – tStop  (TOP solder mask layer)
30 – bStop  (Bottom solder mask layer)
46 – Milling (PCB outline layer)

We selected 46 layer here.

Step 6, Press the Run script button to finish importing the BMP picture and then what you need to do is to measure the size and then adjust the size of the picture. 

Third, After adjusted the size fo all the pictures, you can adjust the position of different picture in the eagle brd file and export it as gerber file. And then what you need to do is  order the PCB online and waiting for it.

Note, The minimum width silk screen is 0.15mm. the silk screen less than it may not be printed.

If there are several picture need to import in the design file, designed the picture as .lbr file would be much easy to move. If you want to know more about how to creat the .lbr file or you like this blog, please give a positive comment to me.
Thanks very much for your reading.
