How is small PCB mounted helical antennas (100 MHz - 1 GHz) assembled in PCB production? See picture below.
I have thought about mounting it both horizontally and vertically, but I can not figure out a process that does not require and abundant load of work done by hand. I plan on producing the PCBs in the thousands. How are these usually mounted and assembled in a factory? Why does almost all antennas include the 90 degree bend at the end? Is it supposed to be mounted in a hole or surface mounted on a pad? How are the antennas kept in place in the assembly and hand/selective soldering process? Is there any special considerations when designing a cutout in the PCB? The questions are many, the answers are few.
