The Gerber files do not specify the order of layers. As long as you don't use blind or buried vias, the layers can be stacked in any order. The file names for the individual Gerber files may vary between different CAD systems, and may or may not imply the desired stack-up order. I always included a "readme" file with my PCB order specifying the desired ...

If you want to swap the layers directly in KiCAD, the option you need is Edit -> Swap layers. After swapping the layer contents, you can update the layer names in Design rules -> Layer setup.

To make sure that you didn't make mistake, install an external Gerber file viewer (not connected to or produced by KiCAD). Then, after renaming, view the project in this viewer and imagine what others would see. Assuming you corrected the vias accordingly, yes, you can rename the files the way you want in order to change the layer.

Though you already got your answer: Better 2-layer PCBs are made of fiberglass mats soaked with resin. The resin is hardened, the whole thing is plated with copper, and you have your raw PCB. During production of an actual board, it is drilled two times: First for all vias an through-hole component pads. They are then chemically plated with metal to make ...

I go one further than Peter in the other answer and include both a "ReadMe.Txt" file and a FAB drawing with each PCB order. The FAB drawing is very detailed and includes information related to stackup, board dimensions, fabrication notes including solder mask and silkscreen ink colors and any special requirements for: Breakaways Bare board testing ...

Probably because you are using a laptop, it happened to me, it only works with the numerical pad. There are some workarounds, have a look at this thread: Altium keyboard shortcuts issues

Shift-S will dim all but the current layer (Single Layer Mode). Repeat to get back. One of the most useful keyboard shortcuts in the PCB editor.

I haven't used Eagle in a while, but if I remember correctly, at the bottom left of the screen after you hit the ratsnest button, it will tell you how many airwires are remaining. I expect the airwires are still there, but since the nearest ground connection is directly beneath the pads then they're vertical (not showing up very well when viewing from the ...

The main consideration is that any high speed or sensitive analog tracks should run over an unbroken reference plane. This could be a power plane or a ground plane, but these sensitive tracks shouldn't run over a split in the plane. Without knowing more about your design I can't say whether you have enough ground planes or if you need to figure out how to ...

They way Eagle works is that air wires will snap to the closest object with the same net name. As @DerStorm8 mentioned the air wires are probably straight up and down making them very difficult if not impossible to find. As long as air wires exist then connections have not been made. Depending on the polygon to connect the grounds can be problematic. You ...

This can be done using Edit -> Move -> Flip Selection (shortcut M I). It swaps all selected objects between Top and Bottom and mirrors objects in the inner layers.

It depends on your design requirements, such as highest signal frequency and EMC (electro-magnetic compliance). But in general for audio type signals it doesn't matter too much. The power plane will act like a ground plane next to signal layers, so you want to use as much copper as possible on the power planes as well. If your traces need to match a ...

Ran into the same problem myself just a few moments ago (this was an old design imported into version 19). Opening the layer stack manager for the 1st time caused my design to gain a sub-stack. It also was showing an error because both the stacks had the same name. I changed the name of the sub-stack and that fixed that error, but I still couldn't ...

Depending on how you've configured Altium to work, you may be able to go into Storage Manager and revert to a previous version of your PCB, even though you've (I assume) not explicitly configured a Version Control System (such as Subversion or Git). Altium consume a fair bit of storage (in relation to the active files) to keep these available, and ...

I do PCB manufacture. From manufacture point, I suggest you to create a mechanical layer named outline layer and then draw the outline or you can draw the outline on the silkscreen layer. It's easy to recognize the board outline for manufacture engineer. For visible/invisible, both are fine. But be sure that the manufacture engineer can recognize the board ...

Vias don't connect to the internal plans unless you have connected it to the net. Example : Stack Up : Top layer - Signal Layer - Internal Plane - Bottom Layer Let's Say Internal Plane is GND. If you place a via from top to bottom which is connected to a Net_17, then clearance around the via will be seen in INTERNAL PLANE. Hence the via will not be ...

Had the same problem. Here is the fix: Go to Rules → Routing Layers, and make sure all routing layers are enabled. To switch the layers without adding vias, press 'L' while routing instead of +/-.


1

To enable snap to any feature on any layer, especially during interactive routing: Press D then O (Design, Board Options), then click box next to "Snap On All Layers". This will allow snapping to anything, any layer. Make sure snap Range is not set too large, else routing becomes a nightmare. Another shortcut is press "Snap" button lower right corner of ...

The freeware version allows two layers, but what you use them for is up to you. Obviously with only two layers, you have to mix power, ground and signal to some extent within those layers. For projects requiring more than two layers, where having separate power and ground layers is applicable, you will want to consider paid versions instead.


1

You get two layers, top and bottom, with the freeware. Defining a layer as 'ground', 'power', 'signal' is irrelevant.
