Dears,
I was working with 11kilos of cell phone boards.
After depopulating all the boards using hot sand bath which was very effective in terms of time, I decided to run the whole batch into 1st HCL hot bath to remove the remaining solder/tin then hot 20% NaOH bath to remove the solder mask.
ALL went well but before completing the whole patch, I found some pinholes in the used vessel so i stopped.
The used vessel was as in the below pic.
Now the question is:
What kind of vessels that could be used without have these pinholes ?
I know that glass may do great job but here I need to use a very large vessel for mass production.
So PLS advsie
