a few of the papers I reviewed and test plan notes
I've been switching back and forth this week between development of the flexible circuit board** and designing the driver board hardware so I am wading in white papers and data sheets. I'm just a one-person team but parallel pathing this project is necessary since these two streams depend on each other. Research is by far my favorite part of the process, there's a lot of uncertainty about whether or not my design will work. I also learn a lot of interesting information that is completely irrelevant to my project. I'm a diligent procrastinator.
I've converted an inkjet printer to become a circuit printer and after reading some research from others who have attempted the same or something similar, I have some ideas on what to test and measure and techniques to get better quality prints. I'll be sharing some photos of the conversion and results from the testing in my next post.
I also learned about how rigid circuit boards are made and it's a pretty wasteful process. One of the reasons why I chose inkjet over other flexible circuit options is that it's an additive method and generates less waste. It's also very fast. Theoretically. Since we have an Othermill CNC here in the lab perhaps I can pit the two processes against each other. If I do I'll broadcast it live.
** using the word "board" when referring to a flexible substrate is a contradiction; I need to come up with a new descriptor
