Does anyone have any experience using zero-ohm resistors in an RF signal path to select antennas?

I've typically used RF switches for this purpose, but that's also when it was necessary to allow the antenna selection to be changed "in the field". But for cases where the antenna selection is a manufacture-time option, I'm considering simple zero-ohm resistors.

I highly recommend using a normal SMD 10pF to 100pF ceramic capacitor, depending on frequency. They’re already used on the board, and tend to be cheaper than zero-ohm resistors, as we buy them by the bazillion rather than the handful.

Are there any guidance on recommended package size and type for a surface mount linear regulator IC on my board that will be hand-soldered?

I am designing a board that needs a couple linear regulators (5.5v to 3v and 3v to 1.6v) but I am having difficulty selecting a suitable surface mount package type and size that will allow me to hand solder the IC to the PCB without too much difficulty.

Is it possible to have rounded edges on a PCB ?

I am DIY a smart round ball. And I want a PCB with round edge to fit the shape of the device. So is it possible thing in the field of PCB manufacturing?

What will go wrong when it is stored at a higher temperature or past its shelf life?

Solder paste should be stored in a refrigerator and it has an expiration date. But what exactly will go wrong when it is stored at a higher temperature or past its shelf life?
