Fiducial tips AKA “Our friend, the fiducial”

Corners

Sdfids
Whatsit?
This is just a couple tips and tricks I’ve figured out on how to use fiducials. Specifically, its for our MDC 7722FV pick and place but theres a good chance that whatever p&p you’re designing PCBs for, its gonna be the same.

What are they?
Fiducials are little target registration marks that are printed on PCBs, they are placed on the top copper layer (and bottom if you’re doing 2-layers) and allow the vision system of the pick and place to recognize where the PCB is at. They are not placed on the mask or silk because they are not as precisely aligned to the parts as the copper itself.

  1. please-
    where can I find the eagle
    sources for your microSD breakout?
    I was just planing to design one myself,
    and would now like to benefit from your work.
    – best wishes

  2. @Lolli32 – this is for an upcoming product, we have not released them yet. we would now like to benefit from your patience and support, perhaps an order when it is released 🙂

  3. Hi,
    I won’t place an order, because I am a really strict DIY person and even make my own PCBs.
    However, I do appreciate your work, attitude and style.
    How could I make a donation?
    – best wishes again
