I don’t understand how to do a "cutout’ on a pc board.
I simply need a rectangle board 185mm wide x 195mm high and then
have a cutout on the top left side 85mm wide x 120mm wide.
This would leave kind of a revers “L” shape.
What is the best way to do this?
Hello
I descibe breefly how I made a custom pc board.
I used Inkscape. I have a finish version. I don’t know in detail how menu options are named in English.
First set the page size to custom size: 185 mm (width)* 195 mm (hight).
Draw a rectangle of the size 185 mm195. Align with page if necessary.
Draw a rectangle of the size 85 mm120 mm. Align top and left.
Choose Path - object to path on both rectangles.
Choose both rectangles by shift clicking them.
Path - separate. You should get mirrored L-shape image.
Fill L-shape with rgba color #338040ff.
You need to have two leyers: silkscreen and board.
I used XML-editor and copied the node I just made. I now have two leyers. I renamed the id of the first one to silkscreen and the id of the second one to board.
Silkscreen layer is not green. So I edited style atribute fill:#338040; to fill:none. Now only board is green. Silkscreen is colorless.
I saved as bare SVG. Not as Inkskape-SVG.
I opened Fritzing and chose pcb tab. Must click “Load image file”. I chose the SVG I just made. I try to include it in this post. You can examine the file with a text editor.
You can design your own custom pcb shapes and load the image into Fritzing… see, http://fritzing.org/pcb-custom-shape/ . Although the instructions are not quite up to date. You need three layers; board, silkscreen, and silkscreen0. silkscreen0 is the bottom layer and can be the same as silkscreen. The ID attribute of the board images itself needs be be named “boardoutline”
excellent! Thanks guys. Got it to work. I also found another tutorial also and was able to do it myself!
Could you share the location of the tutorial for the benefit of the forum?
This should help on the creation of pc boards…
See attached, This is a Donut I made for andy, http://imgh.us/Andys_Donut.svg , to see how it is written.
You need the layer: “board” with the object “boardoutline”. this needs to be a single combined object. Layer: “silkscreen” is the top of the board and the Layer: “silkscreen0” is the bottom, Silkscreens can have as many objects as you would like.
<g id="board">
<path id="boardoutline"/>
</g>
<g id="silkscreen">
</g>
<g id="silkscreen0">
</g>
To import the PCB, highlight the pcb in the view and click “load image file” in the inspector.
