Its quite a while since I have etched boards, but when I did so I used
Ferric Chloride (solid) which I mixed to a very strong solution, Often
there might still be a few lumps floating around in the solution.
I used a heat lamp suspended about 150mm from the tray in which the
etching was taking place. Then when it gets started add a little HCl -
but BE CAREFUL; its goes very quickly - almost strips the board in
front of your eyes! And be careful of the fumes.
Its important to keep gently rocking the tray to keep the solutions
moving.
Anyway, thats my tuppence-worth. Hope it helps.
