Process 01: An open source 2 layer PCB process - part 1

This video presents Process 01, an open source 2 layer PCB production process, including electroless copper plating of vias. In this first part I will go through all the 31 steps required to make a double sided printed circuit board, while in the next video I will detail the preparation of all chemical solutions required by the process. https://hackaday.io/project/180422-pr...
