Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Last week, I visit a PCBA manufacturer for our new project. They not only introduce in-circuit tester but also flying probe tester, which can both ensure the quality level. So, Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

In-circuit test fixtures are built specifically for a given PCB design (unless they have removable pogo-pin cassettes), which is a limitation. However, they generally only cost hundreds of dollars and they can simultaneously connect with all of the test points on one side of the PCB.

Flying probe test systems are more flexible because they can be reprogrammed for an ever-changing variety of PCBs. But the machines cost tens of thousands of dollars and they have a limited number of probes, which can make them unsuitable for loading firmware into the boards.

At what frequency do PCB traces start to act as antennas?

Just interested in PCB design. I am wondering whether PCB traces start to act as antennas at some frequency. Anybody knows?

What equipment is used by professional PCB manufacturers?

This month we plan to find a proper suppliers to produce PCB for our new products, a healthcare watch. One of our supplier assessment items is about production equipment, which I know few about them. Can you share some common equipment which professional factory may use?

Do modern LED lights use thermal vias?

I have a technical question about thermal management with mid-power LED diodes.Do you use thermal vias on the PC board anymore? Either under the LED diode footprint or even around the footprint?
Depends on the application limits and cost targets.
