Hello,

Can anyone recommend a supplier for alkaline ammonical etchant and
replenisher?
We wish to try an alternate source to our present supplier.

Also, can we add ammonia (ammonium hydroxide) to the main etch tank and
add the replenisher only to the subsequent chambers?

Finally, what kind of transportation costs can we expect?

Thank you, Dan Brandler.
