Common enough. The process is called “Z-axis milling“. Used for LEDs sometimes too.
You can even bury low-profile parts such as bypass capacitors and resistors in cavities entirely within multilayer PCBs.
It requires extra steps so expect extra costs or MOQ or both. For small quantities the costs may be prohibitive, even from China.

I’m making a 4 layer PCB prototype that uses a bluetooth mcu connected to a 2.4GHz chip antenna. I’m thinking about what to do with the feedline, whether it should be buried on one of the middle layers, or left on the top layer. To get a 50 ohm line, should I choose top layer with 13-mil width or buried miccrostrip with 7-mild width?
We have a a solar energy product brand. I am just in trouble about product R&D. Why does the my solar charger circuit fail to output power when connecting to solar battery? Anybody could help?
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?
The space of printed circuit boards (PCBs) is often at a premium in modern, compact product designs, optimizing PCB size has become an essential consideration.
The printed circuit board design is based on the circuit schematic and implements the functions required by the circuit designer. Printed circuit board design also
