Stripline trace width calculator

Stripline:    Signal traces that are routed between two ground planes on an internal layer are commonly referred to as stripline routing. Striplines are of different types based on the height of substrate between stripline to top or bottom conducting layer. If both the height is the same it's a symmetrical stripline and if its different it is called an asymmetrical stripline. There are advantages to such an arrangement, most important of which being that the electromagnetic radiation is entirely enclosed within a homogeneous dielectric, thus minimizing emissions and providing natural shielding against incoming spurious signals.  

They are efficient because they don't radiate signal, as the conductor is well protected. They are convenient because striplines are easier to manufacture compared to standard capacitors and inductors. Just like any other electronic component PCB traces does also have their maximum rating.The maximum current that a stripline can safely handle is a function of its width. Using this calculator you can relate the trace width to its current carrying capacity and temperature dependency based on IPC-2221

IPC standards:    IPC is the trade association for the electronic interconnection industry. It provides standards for the assembly and protection of electronic equipment, as well as training, market research and public policy advocacy.

IPC-2221:        It is a generic standard for the design of PCBs. Within the 2220 series, there are also specifications for specific types of PCBs such as rigid, flex and MCM-L. It addresses topics like design layout, parts lists, materials, mechanical and physical properties, electrical properties, thermal management and more.
