PCB Trace Widths: Optimizing for Impedance, Density

In the layout of printed circuit boards, width plays an important part, especially in the metal connections fabricated into the board called “traces.” Traces conduct signals to and from the pins of the components soldered to the board and carry varying amounts of current depending on the net. Additionally, the signal’s traces may have special…

Component Obsolescence and Future-Proofed Assemblies

Few feelings are worse than performing a part buy and realizing the components aren’t suitable for the design as planned. Whether incorrect package styles or electrical parameters, the result is a delay in manufacturing while waiting for the next shipment. An even more ghastly possibility is the inclusion of components designated for obsolescence, which can…
