PCB design software is very helpful for computer-aided design (CAD) that increase efficiency, find error and problem areas quickly, and generate files for fabricators. Furthermore, the design files can be analyzed for missing or incorrect content, avoiding traditional manufacturing questions and issue back-and-forth communications.
Design for Manufacturing (DFM) applications help both designers and fabricators to validate manufacture-ability of the resulting design by analyzing functions. Without a DFM tool, PCB designs will be impractical, costly, or even impossible to build as designed.
Computer Aided Manufacturing (CAM) software is used by the manufacturer to validate and automate the actual fabrication processes.
All in all, these sophisticated tools make multilayer PCB design and manufacturing more efficient, streamlining the multilayer pcb manufacture process.
