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. Zo, 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. Echter, 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.

Hoeveel speling moet u aanhouden in de gaten in de componenten die door de gaten gaan??

Is er een algemene regel over hoeveel speling u moet toevoegen aan componenten met doorlopende gaten?’ gaten zodat ze gemakkelijk passen? Bijvoorbeeld, if I have a component with 1mm pin diameter, what should the diameter of the holes for it’s pads be?

What are primary and secondary sides of PCB?

I am designing a 2 layer PCB with components on both side of it. SMT components are one one side of PCB, but TH (door gat) components are on both sides. I need to understanding something mentioned by the supplier called primary and secondary sides.

What is the proper zero orientation for a SMT LED?

According to IPC-7351, the cathode should be on the left for a molded diode. Echter, when I use component wizard of my suppliers to create a diode, it places the cathode (K) on the right. Does it depend on the manufacturer? How does the assembly house know which way is correct?
