Is via-in-pad bad for manufacturing?（thru-hole hollow-centre via）

I see some videos online that shows via-in-pad during manufacturing. But I don't think it is a good way, is it?

Not recommended, because some solder will wick down to the other side and the component on top will not solder correctly.

Remedial measure:

Use capped
Filled vias when doing via-in-pad to stop the solder draining away.

Remark: Before designing via-in-pad, don’t forget to talk to your PCB fabricator to find out what their capabilities are, and how much extra this costs.

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?

Can we do wave solder the through hole parts without masking it?

We would like to do wave soldering for the through hole components. All through hole components are top side of PCB. Only test points, which require mask during process, are on the bottom side. So there is a extra labour cost at adding and removing the mask. Can we do wave solder the through hole parts without masking it?

How do I use two antennas with a single Bluetooth module? (BLE repeater)

I am working on a project that uses small Bluetooth low energy (BLE) beacons to track important items. Is there a way to connect two antennas to a single BLE module that could either listen/broadcast on both antennas or multiplex between the two? Or any other idea?
