Etching, Drilling..

This part of etching and drilling is very tricky part...I have to do it carefully..In this section, I have choose UV pcb board for my standalone arduino because it is much easier than the usual one..This UV only takes 5-10 minutes to complete all the process compared to usual one which takes about an hour to do it..So here's the pictures of my etching and drilling...Enjoy!
