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. (more…)
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. (more…)
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.
In the middle of a project we are developing, we felt the need to create some PCBs (printed circuit boards) so we used the opportunity to prepare our next workshop. We experimented and got to know a new method for creating PCBs, a method usually known as toner transfer.
