Are SMT components bad for high voltage applications?

Many assembly factories are asking for SMT jobs, while I think through hole would be a better option for a high voltage application. Before the high voltage project is started, we need to make a call on SMT or Through hole parts. Is there a study on this?

Firstly, check whether your PCB is high voltage. Generally speaking, high voltage is defined as starting at 1000V.

That being said, there is absolutely nothing wrong in general with using surface-mount parts in a device running at these voltages, so long as the parts you are using are rated for voltages you are using them at. Keep in mind as well that you do not need to make a single decision between SMT and through-hole parts. You can mix and match both within a single design.

Is it OK to bend a VIA in a Flex PBC?

On a Flex Printed Circuit (FPC) made out of Kapton polyimide, will anything bad happen if I put a VIA in a part of the FPC that has to bend? VIA size: 0.2 mm hole diameter in 0.4 mm copper diameter. FPC bend radius: 0.7 mm. Kapton thickness: 0.2 mm. Copper weight: either 2 oz or 1 oz (I haven’t decided yet)

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?
