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.

Does anyone have any experience using zero-ohm resistors in an RF signal path to select antennas?

I’ve typically used RF switches for this purpose, but that’s also when it was necessary to allow the antenna selection to be changed “in the field”. But for cases where the antenna selection is a manufacture-time option, I’m considering simple zero-ohm resistors.

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 (through hole) components are on both sides. I need to understanding something mentioned by the supplier called primary and secondary sides.

Can leaded BGA chips be reflow soldered with lead-free process?

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable. But now BGA chip is only available in lead-free balls. is it ok to solder leaded BGA chips with a lead-free (thus, higher temperature) process?
