Description

A logical extension to the Kicad workshop (electronics design) is to realize the designed PCB. There are 3 ways to produce PCBs at FIXME (with the required components):

• PCB Milling with a CNC Router
• PCB Etching using toner transfer method
• PCB Etching using the photosensitive positive method

Goal

• Make custom PCBs for FIXME members and projects.

Obstacles

PCB Milling with a CNC Router:

• Cost
• Make a lot of dust

PCB Etching using toner transfer method:

• Use chemicals requiring precautions for use

PCB Etching using the photosensitive positive method:

• Use chemicals requiring precautions for use
• Need an insolation box
• Number of step for the process

Components

• Iron(III) chloride / Perchlorure de fer Corrosive!

or

• HCl + H2O2 / Acide chlorydrique + Peroxyde d'Hydrogène (eau oxygénée) => HCl+H2O2 method on Hackaday

Safety

Equipment:

• Gloves
• Goggles
• Lab coat

Docs:

• Iron(III) chloride / Perchlorure de fer : (de) Sicherheitsdatenblatt (fr) Fiche de sécurité
