Reveal your circuit

Engrave your circuit

Thanks to Aurelien for the tip

Usually, everybody use the old boy iron chloride for engrave his circuits.But that needs a machinery that costs between 50 and 700$­­­­­­­­­.However, there is an other solution (that I use) in which you make your own solution.

You also need:

Chloridric acide Hydrogen peroxide (H2O2) at about 130 vol. Water

Then melt 1/2 water, 1/4 H2O2 and 1/4 acide.Be careful : those products are extremely dangerous so use glove, glasses, do not let childrenn paly with...

When it's done you have very few time so make it little by little. Then you have to feed your circuit into the solution just for 30sec.

You do not need to heat or so...it does it by itself.

Please do not reuse the solution since it won't work a second time!! (engrave will use more than 5min)

Reveal your circuit

Le révélateur est en fait une base forte (CF cours de chimie), car composé exclusivement de soude. Il parait donc logique d'utiliser une autre base forte pour révéler ses circuits (du moment qu'elle ne régait avec le cuivre, CF redox !). Cette vieille méthode m'a été envoyé de nombreuses fois par mail : utiliser du DESTOP ! C'est quoi ? C'est un detergent utilisé ménagerement (ça existe ce mot ?). Autrement dit, au lieu de vous ruiner pour 5FF de revelateur (attention l'economie du siecle, allez plutôt vous acheter un banco), vous chourrez un peu de destop a la vieille, vous faites une dilution 20 pour 100 (1 vol de destop pour 4 d'eau !). Normalement pas de probleme!
