CNC made PCBs (1)

Posted on Monday February 11th, 2013 by nosense

Basic step in electronic devices construction is PCB (printed circuit board) manufacturing. Preparing PCBs at home is quite boring and long task. That made me think how to simplify this task. I have working CNC router (as described in CNC section of this web) and I attempted to use it in PCB manufacturing process. In this article I will describe one of two procedures I finally found out. It is based on scratching paths in covering film on PCBs and subsequent etching. Continue reading →

On my home server I have available more than 1200GB and electricity costs are around 40$ per year. Server can of course provide more services than backup and synchronization. Continue reading →
