Benodigdheden printplaten etsen:



PER PRINTJE VAN 10x15 ~€1,5, dit is redelijk groot, dus kan altijd nog in 2 worden gezaagd

The chemicals we use from left to right: Ferric Chloric Acide, soda water 20mg / 1l, stronger soda + baking powder

Manual (draft, definitive version will show up as an infrastructure project if finished)


To make PCB's we'll use acid to etch them. In our case we use Ferric Chloric Acid (Iron(III) chloride, FeCl3). This stuff will leave permanent marks if it touches your clothes, and can eat away metal objects if they come into contact. This stuff is also corosive.

Wear a lab coat / bad cloths, and wear gloves. If you don't want to wear gloves make very sure you take your rings off your fingers.

DO NEVER POUR THIS STUFF DOWN THE DRAIN, IT WILL EAT AWAY METAL PIPES. It should be disposed off as toxic waste.

No toxic fumes are released when you use it at room temperature.

Step by step manual

Step1: cut the PCB to size, and sand it with a sand paper (I used a 240) to sand away oxidation, and other stuff on the surface. Make sure the board is a little bigger as the PCB you designed. Don't touch the metal surface with your fingers after sanding it.
