In its place, put an array of small squares of Fill, and don't put them over the holes (which are soldermasked, so there's no point). The following is a brief explanation of these settings, You can also ignore these setting when generate Gerber file. Each layer of PCB and solder mask receives its own clear and black film sheet. Going to 8 is another major price step, like going from 2 to 4 layers. Coming from a much simpler software such as Eagle CAD, some of them took me a while to figure out. Prototype PCBs for Only $2. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. Just like photoshop when you compose an image it has several layers to it say foreground,background,subject etc. Such as Solder mask colours, Silkscreen colours, Surface finish, Finished Copper weight, PCB thickness and any slot details or cutouts. Select the layer you need to export on the gerber file. A Gerber file is simply an image of how one layer of your circuit design looks. More information can be found in the Altium help files Figure 1 Setting the Minimum Clearance value. How to design a standard PCB layout using Altium Designer This document is currently in a work in progress. Please leave a comment if it should be made as 1 layer with mask both sides. Comparing Altium And Cadence PCB Layout Tools. We are excited to announce that millions of electronics parts on SnapEDA can now be imported into Proteus. 005" available for Custom Spec upon request) Note: We rout to your board size using the center of the board outline on your mask layer. I am new user who is learning pcb design using altium designer 18. The default presentation of layers in the PCB editor is to always show the Multi-Layer as the top most layer. This has been true for many years in Protel/Altium PCB Editors because the layers are not separately editable - you can add openings to the mask layers manually, but you can't delete the automatically generated openings produced by the primitives on the surface layers.
