For this method, since its electroplating, its done prior to etching. I
am not sure if all etchants will work on the tin plating though. The

The chemical (electroless) methods are used after etching. This is the
usual hobby method of tinning, but its way too exepensive for me,

I normally use flux and tinning with a hot soldering iron. Its ok for
small boards, but a bit tedious when you start doing bigger pcb's.
