![]() ![]() I lined up the edge of the connector’s layout with the edge of my PCB’s dimension layer. However, I have to keep the back panel off, because the USB connector isn’t offset enough. ![]() It was my first experience with a laser cutter and one of my first PCBs to run through my toaster reflow oven. Redrawn radio for Quadrotor, to check clearance.īinBoo is one of my favorite projects. This check list item requires a bit of experience or a lot of 3D CAD work. That’s because when I got the first board back, I realized the battery was on the bottom layer and had no way to push the battery out from behind! So that hole lets me stick a small screwdriver inside to push out the battery. Notice right above the RTC (DS3212) that there is a small hole. The example here is from my Binary Clock controller. At the very least, make sure you add some holes to the board’s design. I get so caught up in part placement, I forget to consider how I’m going to mount the board into a case. One of the biggest mistakes I make with every PCB, is to forget mounting holes. Not all (cheap) services allow cuts inside your design, so double-check before you send it out. The example above, you can see I made a cut-out for the Wii’s accessory connector. Most board services will let you cut almost any shape (but charge you as if the board fit inside of a quadrilateral.) So make sure the shape of the dimension layer is what you want. The router uses the dimension layer to run the cutting bit.
