Ask HN: Most effective non-destructive way to reverse-engineer a PCB at home?
3 by keks24 | 1 comments on Hacker News.
Hello! I am looking for effective non-destructive ways in order to reverse-engineer PCBs at home. I found or could only think of... ...trying to shine through the board with very bright light. ...scanning the PCB. ...using a self-built, well-isolated X-Ray chamber[1][2], which, if done wrong and without special meters, can cause me cancer. ...using ultrasonic waves. ...using acoustic microscopy[3]. All other ways, which I have found so far[4] are destructive; the best of them is using sandpaper and sand down each layer. I would like to avoid these. Are there other effective non-destructive ways, which are applicable at home? -Keks [1] https://ift.tt/OuIJnMd [2] https://ift.tt/12zxNWL [3] Slide 48: https://ift.tt/CYQ5wo6 [4] https://www.youtube.com/watch?v=O8FQZIPkgZM
