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.

What kinds of test is suitable for low volume PCB order?

I’ve ordered fabrication and assembly of small PCB batches (100pcs) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Then, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.

How can we identify the BGA area of PCB?

Hear about BGA PCB Assembly service, but I never order it. How can we identify the BGA area of PCB? Just very curious.

How can I connect my small PCB with sensor to the bigger PCB?

My small PCB is mounting a very sensitive fragile sensor on the top surface that has to be wire bonded to the PCB, so I am trying to design a smaller PCB that can be surface mounted to the bigger PCB. How can I get some kind of thin footprint for interconnecting the two PCB boards?
