Components can be embedded on any internal signal layer. Multiple layer stackups can be defined in a rigid-flex design, and additional coverlays created. These challenges can be met with Altium's PCB design technologies.īoards can be made in any shape, and designed as a rigid board, rigid-flex or pure flex. These tight design requirements demand close collaboration between the electronic design and mechanical design domains, demanding the easy passage of design data between them. Compact, unusually shaped modern electronic products require compact, unusually shaped printed circuit boards which are often implemented as rigid-flex structures - these boards can have curved edges and cutouts, requiring carefully positioned components. Lower device supply rails introduces tight demands on the allowable voltage drops, requiring careful design of the power distribution network.Ĭombine these, and the modern PCB is a dense, multi-layered engineering design challenge.Īs well as these more demanding electrical requirements, the mechanical requirements have also become more complex. Rising signal speeds has also seen the PCB interconnects change from being simple copper conduits that carry electrical energy, to behaving as high-speed transmission lines, requiring design techniques to cater for this. Today, the components have shrunken so much they are measured in fractions of a millimeter rather than centimeters, and track widths have shrunken from being 10 mil wide, well spaced lines, to thin, 2 or 3 mil hair-like lines tightly packed together. In the early days of printed circuit board design the demands on the PCB were simple, the board provided mechanical mounting for the components and connected the appropriate pins together - implementing the logical design defined on the schematic. Inside every electronics product is a printed circuit board, or PCB. Welcome to the world of board design in Altium's electronic design software.
