PCB Layer Stackup Technology and Terminology To do this, the designer must be able to define multiple PCB layer stacks and assign different layer stacks to different parts of the rigid-flex design. Since it is fabricated as a single entity, a rigid-flex PCB must be designed as a single entity. Rigid sections of PCB connected via flexible sections of PCB – an innovative concept that supports the design of creative and compact electronic products. By joining rigid sections of PCB together via flexible sections, complex, hybrid PCBs can be designed that can be folded to fit into unusually shaped enclosures. However, technological innovation and refinements in the processing technology have led to a number of revolutionary concepts in PCB fabrication including the ability to design and manufacture flexible PCBs. To design a single printed circuit board, it is only necessary to define a single layer stack, which defines the entire board area in the vertical direction, or Z plane. Also, if you get it go out and find available projects in Altium so you can see how a "real" design looks in Altium.To learn more about how a PCB is made, refer to The Board article. That's better value than a lot of the classes you'll take in college/university. If I assume 3 years at $120/yr, that is a very cheap price to pay for some valuable experience(assuming you practice and use it). You don't want to have to learn the basics on the job with someone looking over your shoulder. If you learn the basics of Altium, you'll be glad you did when your employer asks about it during an interview, or you're required to use it on the job. You are much more likely to find Altium in you job later on, and since you are a student, I assume you will be going on to finding a engineering job. If you want to have a chance of importing to another package in the future you'll likely need the ASCII version, but Altium natively supports the binary. When you create a project in Altium, be sure you save the binary and ASCII versions of the board. I think it's worth it to have experience with multiple platforms.
