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?

Yes.

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.

What Others Are Asking

Can I leave a through hole pad off one side of a machine-fabricated PCB?

I’m designing a two-layer PCB and I’m very inexperienced. A third-party company will fabricate them. Now, I have a PTH part with a number of closely spaced pins. However, I can’t greatly simplify routing by running traces unless I eliminate the pads for certain pins on one side of the board. So can I leave a through hole pad off one side of a machine-fabricated PCB?

Where should I store PCB?

I have received the final prototypes from manufacturer and all is good after our checking. And we want to keep it well. Do you have any tips about that?

Why does an LED PCB need a heat sink?

The supplier whom I ordered LED PCB design is asking details of LED heat sink, but actually we have no idea about it. Why does an LED PCB need a heat sink?
This is a new project for our house supplies brand. Any tip can inspire us?
