The course, which is entitled, "PCB Stackup Design--Optimizing Signal Integrity, Manufacturability and Reliability of a Printed Circuit Board," focuses on high-speed differential signaling issues.
Therefore, it was an interesting challenge to ensure controlled impedance, and it was difficult to come up with a board stackup that would leave adequate space for 80Q, as well as 100Q, without becoming too thin and difficult to manufacture.
All the other information--function of images and image elements, stackup, materials, colors and general instructions--is, frankly, a confusing mess that forces CAM engineers to search for, interpret or even guess designers' intentions.
