What’s the worst mistake/problem you’ve made during a project, and what did you learn from it? We are asking e14 in our Join, Share & Win Competition

E14Alice

Hello Everyone!

Hope you are all doing well. I’m excited to announce that this month's AskE14 question is: What is the worst mistake or problem you've encountered during a project, and what did you learn from it?

Sharing your experiences can help others identify similar challenges and understand how to overcome them. I hope this discussion will be beneficial for those who are just starting out on a project or feeling stuck with a problem.

Here's the question:

  • I once forgot to add power connections to two ICs on a PCB I was designing, and we send to manufacture like a 100 of them, so it was a comically tragic fail.

    This happened because the parts library (containing that family of ICs) had the clever idea of use "implicit" power connections that wouldn't show up as pins on the schematic editor (so I never even had the option to wire the power up to those pins), but they would automatically connect to any node network named Vdd and Vss. Which was kinda smart, except that I didn't know, and I don't think that I named my power pins anything remotely close to that. As a result the pins were left floating.

    Now, it was mostly my mistake because I didn't run the DRC, which would have detected the floating pins, and I didn't even think once "what are these two floating pins for?".

    At any rate, after that incident I always run the DRC, AND I check that all ICs and components on the PCB are connected to power.
