How can I separate PCB antenna and SMA connector?

I am designing a prototype PCB for a Lora node. It will have an SMA connector (J2) and a PCB antenna. Switching RF connectors are not available in my area, so as an amateur enthusiast what is a good way to separate the antennas?

They usually put a 3-pad solder jump.

The central pad is connected to the LORA integrated circuit.
The left pad is connected to your SMA connector.
The right pad is connected to the printed antenna.

How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

Can leaded BGA chips be reflow soldered with lead-free process?

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable. But now BGA chip is only available in lead-free balls. is it ok to solder leaded BGA chips with a lead-free (thus, higher temperature) process?

What do we need to check before releasing a PCB design?

After making efforts in a period, I finally finish my PCB design. Next step is releasing them to factory for production. To be honest, I don’t want any mistake on my file which may interrupt further prodution process. So what points should I pay attention when I double-check my design?
