Hello , I have a question about the dust of the PCB , is it toxic or not ? because I read that made by fiberglass and resine , thanks
It's not toxic using the usual definition, but you shouldn't be breathing it. It could cause respiratory problems.I have a question about the dust of the PCB , is it toxic or not ?
PCB resin (aka FR4 - which is the most common) is fiberglass. It's dust most certainly _IS_ toxic, and should not be inhaled (in the event someone is cutting or drilling the PCB).It's not toxic using the usual definition, but you shouldn't be breathing it. It could cause respiratory problems.
I only use FR2 boards on my mill. Apart from the lower risk from dust, the tools last a lot longer too.If you mill you are really going to want a dust extractor and wear a dust mask. But you still have a problem with residual dust in the workspace.
Are you sure that FR2 is less "toxic" than FR4? FR2 is a phenol formaldehyde resin -- the sort of resin that has been a subject for debate on its use in homes because of its toxicity when burned.I only use FR2 boards on my mill. Apart from the lower risk from dust, the tools last a lot longer too.
