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-process-01-an-open-source-2-layer-pcb-process Other works cited in this video: Example of 2 layer PCB without plated vias, using rivets: https://www.instructables.com/DIY-Professional-Double-Sided-PCB/ Conductive graphite and electroplating process experiments: https://blog.honzamrazek.cz/2017/10/diy-through-hole-plating-of-pcbs/ Electroless copper plating experiments: DIY HOMEMADE: https://www.youtube.com/watch?v=90VN_80zxAQ guser210: https://www.youtube.com/watch?v=EEmW4xBFiac Images used in this video: Image of PCB factory in the video taken form Wikipedia (https://en.wikipedia.org/wiki/File:PCBs_hanging_in_electroplating_machine.jpg) 1967 PCB photo taken from Wikipedia (https://en.wikipedia.org/wiki/File:S111FlipChipBack.jpg) 1943 PCB photo taken from Wikipedia (https://en.wikipedia.org/wiki/File:Mark-53-proximity-fuze-1943.jpg)
