It means lC and component which is connected to Ground. If a Ground plane is made as a separate layer, all these pins are to be connected. It can boost the performance of circuitry in certain conditions.
Sometimes vias are used for connections to ground planes.

In common, I use 2 ounce copper as rule for all my PCBs. On a recent board, I am using a 0.5mm pitch, relatively large micro, and noticed the pads aren’t very flat. Assembly went fine with the protos, but I’m wondering if 1 once copper would provide for a flatter landing service. Any advice on assembly reliability related to copper thickness for such devices?
Wireless charging is so convenient for user because it doesn’t need any wire, but it is not so popular as market. It must be some reasons in supplier side, isn’t it?
Every computer PSU I’ve taken apart uses through hole components, though occasionally (not in all cases) surface mount components are found on the bottom. Don’t these have to be hand assembled? If so, why are they still doing this? even though labour costs are low in China, it still must cost less for a machine to pick and place SMT stuff.
Have you ever opened up the case of a broken smartphone or smartwatch? If yes, you will be familiar with small circuits packed into such
