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.
eLab will organize a new workshop about “Electronic instrumentation for beginners based on Arduino” in November 28th at 5.30 pm.
Following the last publication about PCB (printed circuit board) manufacture, we present another useful project. The corrosion with iron perchloride, is a slow speed process, but we can accelerate the process, by agitating regularly the solution. To do this, we created a simple device, able to make an automatic PCB agitator, using an old DVD desktop drive. Continue reading PCB Automatic Agitator
In PCBs manufacture, it’s required to handle very carefully the printed circuit board, due not compromise the work done so far, and to avoid the risks of the chemicals used in the process.
One of the tools used in the manufacture process of PCBs are the tweezers. These can not be in metal material, because the perchloride of iron, is a metal corrosive.
eLab leaves here a suggestion, of how to make various sizes of tweezers. From a PVC strip, and the help of a hot air gun, we can mold the PVC in the form of a tweezer. Continue reading PVC tweezers for the manufacture of PCBs
We announce that eLab will organize its second workshop next Wednesday, November 21st at 4.30 pm. This workshop will be about the different methods for making PCBs (printed circuit boards), where each participant will have the opportunity to learn about some common methods and make its own PCB.
