For up-to-date component libraries, check the They are relatively old and don't feature the most recent components, however they provide a very useful collection of standard PCB footprints. Altium Designer librariesĪ collection of libraries is installed on the computers available in MEB 494 on C:\Users\Public\Documents\Altium\Library (see here for the source files). The EPFL logo (required by the ACI when producing printed circuits) corresponds to the E character. You can download the DXPSymbols.ttf font, which contains the EPFL logo and some other potentially You can download a cheatsheet with the most useful keyboard shortcuts.

Experience will dictate what is useful to you, and creating PCB templates with expectant usage of these layers will likely prove to be valuable.Here are some points mentioned during the tutorial. They can be for whatever you need them to be ultimately. I also use a separate layer to sketch out bend locations and jot down the radius/angleĪnother mechanical layer has dimension callouts that are used when generating documentation from a specific output job container to make clean PDF prints When designing flexirigid PCBs, I use separate mechanical layers for outlining the flexible and rigid regions (top FR4, polyimide.) This is also useful when conforming to IPC-2223, such as keeping a minimum distance between plated holes from rigid to flex, as I can clearly identify where the overlaps are. Sometimes I let the manufacturer decide what's best, but other times I might want a specific clean edge in a certain location. I have a separate mechanical layer for the outline of the PCB (File > import > DWG is a highly used command) as well as keep-outs.ĭepending on the manufacturer and the board, I have a specific layer for the cutting outline, ie the path the 2mm routing tool should take. Component-housing collisions and interferences are not fun. I use Mech 1 for 3D component bodies - both simple extruded primitives for things like passives, but also more detailed, manufacturer-provided step models. I might will definitely argue about the board outline, screw-holes, general space etc, and as such I need dedicated places to convey this information to my colleagues, my suppliers, but also myself.
It's a give-and-take relationship, but as a PCB designer I'm mostly given mechanical constraints to work with from mechanical engineers as they stake their claim to available space.
