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.
This was the first part of the construction of a development board for the PIC16F88 microcontroller, which will be completed later in another workshop.
Once again, the feedback from the participants was very positive, from where we could get some conclusions:
- Most of the participants feel confident enough to make their own PCBs, admitting however, they need a little practice.
- It was considered a very useful and interesting workshop.
- The participants are wiling to participate in future workshops and their favorite topics are: robotics, PCB design (Kicad), microcontrollers, webdesign, raspberry pi among others.
We also want to give a special thanks to the Electrical Engineering Department of the University of the Algarve for their help in making this workshop possible!
