It also has an option for "plated" which means the inside of the hole, not the pads, but if that's what you mean, there should be in the lower to middle left side a check at "Plated". Then there are options for layer stack (you can define the pad for all layers independently with a special setting) or for "simple", if you chose simple all layers should be the same pad shape, if you have a full-layer-stack option selected, verify that all layers have a pad laid out. In 2D view you can double click a pad, and then it asks you if you want to see the options for the component or for the pad, choose pad. Altium's 3D live view is very buggy if you don't have a top-range graphics card. If this is twice the same component (left and right) and no differences have been made, it's quite possible it's a bug.

Kinda stupid, probably the way the tool came originally from through-hole days and that legacy code just continued on counting a SMT pad as 0-mil hole. It's how Altium counts a top or bottom layer surface mount pad with no hole. You'll get something like this, which you can count what you expect and find the error.īy the way, don't get thrown by the 32 0mil pads. To do so, click again from the PCB view: Reports -> Board Information.Ĭlick Report, turn All On (really you only need Non-Plated Hole Size, but they can all be enlightening). Click OK and go through the wizard.Īn easier way to confirm NPTH (Non Plated Through Holes), which sometimes are desired like for mounting holes or light pipe mounts that get glued, you should read through the board report.

To do that, from the PCB view, click Tools -> Update from PCB Libraries. Now you're showing us the footprint is fixed in the library, but my guess is you forgot to actually update the instantiated footprint on the PCB from libraries.

My guess is you made the top or bottom layer 0 sized. That, or also possibly you generated the footprint incorrectly at first, using the "top-middle-bottom" or "full stack" options, without really knowing what you're doing. My guess is either you have some sort of net tracing on and it's dimming layers, so make sure in the bottom right you click "Clear" near "Mask Level" In fact, I trust 3D view the most to see what's going on sometimes! For example, it will even properly display tented vias. I've never seen Altium be as buggy with the 3D view as others here claim, even before I had a good graphics card.

Rather, it looks like they are missing the pad on the top or bottom, because when you see that darkish almost-transparent core of the PCB, it's like you have no copper or soldermask there. In addition, in electronic products with both analog and digital circuits, the printed boards often separate their ground lines to form an independent grounding grid, which can also be used as a basis for identification and judgment.From the picture, it looks like the holes are actually plated (as your settings indicate). When the factory is wiring the printed circuit board, in order to prevent self-excitation and anti-interference, the ground copper foil is generally set to the widest ( high-frequency circuits often have large-area grounded copper foil), the power supply copper foil is second, and the signal copper is used.

The power and ground lines can also be found from the three-terminal regulator pins. Taking the power supply circuit as an example, the negative terminal of the rectifier connected to the secondary of the power transformer is the positive pole of the power supply, and a large-capacity filter capacitor is generally connected between the ground and the ground, and the capacitor casing has a polarity mark. Correctly distinguish the ground, power and signal lines of the printed board.
