Workshop summary: Making PCBs

After another workshop in eLab, we can be proud for organizing another successful event. In this second workshop, all the participants had the opportunity to learn about some of the most common methods used for the homemade manufacture of printed circuit boards. A total of 5 methods of transferring the circuitry to the board were demonstrated: UV light exposure with acetate sheet and greaseproof paper, toner transfer to a magazine sheet and to foil and finally by applying a negative dry film. Also, 2 corrosion processes were demonstrated: through iron perchlorate and through a mixture of muriatic acid and hydrogen peroxide.
