Hi !
This statement is grate mistake !!!
" Flash it over " it means , plating Nickel-Gold on unteched copper while
Nickel-Gold is used further etch resist for copper . This is time consuming
operation , problematic yields , poor resolution , very problematic for
fine lines and dense SMD . There are some ways to plate on etched boards ,
but this the board must be re-design .
