Interesting clear vinyl PCB technique

Hi everyone, just wanted to share with you an interesting technique I experimented with this week. Its application is mainly on clear materials. It involves printing on a layer of clear vinyl, then overlaying a patch of copper over, onto which the tracks are cut. It allows you to create illustrations on the bottom of the tracks, of the tracks themselves or something completely different. You can check out my documentation if you're interested. http://fabacademy.org/2019/labs/irbid/students/tarek-asfour/week4.html
