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.

I am getting a PCB manufactured for a project that I am working on. One of the parts, the A4950 motor driver, has a “pad” on the bottom, which is meant to be soldered to GND of the PCB for thermal dissipation. I was thinking about the prototyping, and I am unsure how I would go about (using a soldering iron), soldering the pad on the bottom.
Although the adsorption of moisture by FR4 is quite low, what is the best way to minimize it or eliminate it completely?
I believe I have heard of putting a plugged via right next to a mechanical pad so that the board is stronger there. But I’m not sure what the implications are for putting a via on the pad?
