Hi,

Did anybody use the disposable aluminium trays (the one you use for
food) for the developing, washing and etching of a PCB?

Thanks
Zohar

developing what ? If NaOH, then no.
Washing is ok. Persulfate etching might be ok for short
while, or only until the aluminum oxide layer holds out.
FeCl3, CuCl2+HCl, forget it.
Whats wrong with non disposable plastic trays ?

Probably nothing is wrong with it, but I like the idea of throwing
away the 10 cent trays after use instead of having to clean them.

Cleaning is at most a quick rinse. I don't even rinse the
developer, just dump the solution and put away in the storage box
for next time. Dried salts left from a previous PCB session is
not going to effect anything.

About the worst thing you could use. Both developer and etchant will eat
aluminium.

I use cheap plastic food containers.

Thank you Guys,

Got the idea.

be able to use it again and again and again....
