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…)
