Is PCB poisonous?

We are a green energy brand which sells solar water heater. All of our products are almost use PCB. And we want to know whether it is poisonous to human and environment?

Ja.

Electronic parts on PCB generally contain lead and other sulfides. In the past decades, many manufacturers have said that they will not use electronic components containing lead, but it is not credible and possible. Lead is an important material in electronic components. It is practical to reduce lead but impossible to eliminate it.

How much larger should a plated-through hole be than lead diameter to get good solder wetting?

I’m designing a new PCB where I have a whack of connectors that have to line up with the metalwork. There are some problematic connectors. All 4 pins are round. I want to have the holes as small as possible while allowing for good solder adhesion over the full length of the pin. I’m looking for guidance on how much clearance around the component lead I should have in order to get good solder wetting and adhesion.

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?
