Printed Circuit Board

   So....your PCB should be completey etched by now. Take if off the solution and flush with water. The remaining perchloride can poured in a NON-METAL sink with tap open. OR you can slowly put the solution BACK in the bottle. Just be careful to don´t spill and to leave the black stuff (etched copper, heavier than the liquid) at the bottom and discard it after. Eventually the solution would be less efficient, but at least it wil take a long time to run out of it... =)

Wash evertyhing that got in contact with the solution. Dry it thorougly, that includes the board, which should be like this:

To be able to use the board, you can remove the toner with THINNER, ACETHONE or even with the Steel wool.
NOTE: It is better do DRILL the board before remove the toner. Toner also helps to center the drilling while doing it.

And finally....YOUR HIGH QUALITY HOME MADE BOARD!
 

Have fun...I´m not charging anything for the hints....YET... =)
