I often ask question about chemicals trapped inside of a via and if solder mask can trap air inside of a via. I was told, it's not really that bad. This... -
when you select a via, in Solder Mask Expansion, change it to Manual and check tented

The simplest way to get some work is through your friends who are already working in a company which needs some help with design. Ask your friends, offer...Leave a comment:

Oh, you mean to change the order of the whole pair? Still the same, you may need to change layers.Leave a comment:

There is no other way, unless the chip supports polarity swamping.Leave a comment:

I would recommend to read datasheets and check how the signals for the display looks and if these can be generated by your CPU.Leave a comment:

It may not work in your case as your vias are unmasked (not tented). If they were, you just change transparency of the solder mask.Leave a comment:

No, you don't have to always create new components, once you create them, you can re-use them. I create the components in my videos from scratch, because...Leave a comment:

Once the cap is on the other side, from the point you are asking about, I don't think it is really important where exactly the via is. We just would like...Leave a comment:

It should work. I don't have a specific video about it, but I am using it here - have a look how my PCB panel on the left is set: https://www.youtube...Leave a comment:

Some chips have length matching done on the chip - in that case length in package is not required. About the spreadsheet, this can help: https://yout...Leave a comment:

That feature did not exist in the old Altium. If there was a delay in package, the length was re-calculated in spreadsheets.Leave a comment:

In PCB panel, there is a drop down menu: Normal / Mask / Dim. Try to change it and then click on a net in the panel.Leave a comment:

When it costs you to build a board let's say 10 000 USD, would you trust libraries downloaded from somewhere? That is one of the reasons why professional...Leave a comment:

In the new Altium you can create diff pair classes in schematic. That may be the reason why it is re-writing them.

maybe there is something wrong? why there is the "connection" showing up (the thin yellow-ish line showing what pads should be connected together)...Leave a comment:

this is probably clearance (space without copper) around the via on power layers (?)Leave a comment:
