| == Double sided boards ==
| | Hello ! I'm new on this forum, hope to talk to you soon :) |
| | | I love carsn seotons and tuning, and you ? |
| The process for exposing and etching double sided boards is basically the same as described previously, with the addition of one extra layer.
| |
| | |
| The one thing to watch out for when generating the artwork, is that one of the layers needs to be mirrored, to match the opposite layer, when both come face to face.
| |
| | |
| In Eagle CAD, the top layer is mirrored.
| |
| | |
| Once printed, the layers are, in the case shown, stapled together.
| |
| | |
| The optimal distance between staples allows for the board to be inserted into the "pocket" but not move freely.
| |
| | |
| This helps to keep the board registered, when flipping it around in the UV light box.
| |
| | |
| One of the remaining open sides can also be stapled, leaving one aperture for board insertion into the pocket.
