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.

Project here.

Step 1: Disassemble the drive

First it’s necessary to disassemble the drive removing the electronics and all the mechanisms, except the ones we see in the image below. You should just leave the laser support, his axles, and the CD’s motor.
Bubbling is better.
<p>Sure, bubbling does provide better results. But this is just an alternative method.</p>
<p>I have spent enough agitating etch baths in a similar fashion with poor results to simply point out that bubbling is better, and therefor worth pursuing over this.</p>
Muy buena idea.
great hack!
