Figure 2: PCB showing vias for stitching ground planes The only solution is then to implement ground planes on both sides of the traces that are interconnected by plenty of vias as shown in figure (2). When there is a requirement to route tracks on both sides of the PCB in the same area then a good ground plane is no longer guaranteed. Image credit: Circuit Cellar, Robert Lacoste, R&D consultant, and Trainer, ALCIOMĪ double-sided PCB may be the right choice when it comes to cost minimization.
The power planes are made as large as possible to reduce the impedance. The second inner layer is used for power planes. The opposite side is used for mounting less critical components. When the external layer nearest to the ground plane is used to mount all the high-speed components like RF components using microstrip traces or coplanar traces. This ground plane should never be broken by routing any tracks in it. This ensures minimal impedance between any two ground points in the PCB. A ground plane is a sheet of copper, forming one of the layers of the PCB and covering the entire area of one of the layers of the PCB.

A four-layer PCB allows devoting one of the inner layers to a full ground plane. For best results, a designer should incorporate at least a four-layer PCB. Route high-speed signals over a solid ground planeĪs a rule of thumb, it’s most beneficial to have a common ground plane below signal traces. In an effort to help these PCB designers, we have drafted a list of best high-speed PCB routing practices that will assist them in achieving that perfect high-speed design. Things get a lot more complicated when the design involves high-speed signals.
The gorgeous melodies that have defined the project since it’s beginning permeate the music with crushing low end lurking behind every turn. With fascinating production, lush soundscapes and an undeniable rhythmic balance, Signal Path will give fans a full album of brand new music in its purest form.

IMAGINARY LINES drops SEPTEMBER 1st and will be available as a free download through their websiteEasily Signal Path’s most polished and introspective work to date- the band is at an all time creative high. With packed out concert halls nationwide and an album streamed and downloaded a hundred thousand times, Signal Path suddenly found themselves back at the forefront of a scene they had once helped pioneer.Īfter the success of CLASH and two of the most successful national tours in their history, Signal Path permanently relocated to Colorado to complete their next full-length studio album IMAGINARY LINES. The viral success of 2009’s CLASH amongst fans was almost beyond belief, and the overwhelming support elevated the band to a level of national prominence they’d never experienced. After a two-year hiatus they released their second FREE album during the summer of 2009. Born in the unlikely mountain enclave of Missoula, MT, Signal Path has released six full-length albums to date. They create a depth and intricacy of sound that become more commanding every time it’s heard, and by blending live instrumentation into their production they create a live experience that is as beautiful as it is intense. Signal Path bends musical genres and deep melodic ideas around a core of unrelenting rhythm and massive low-end.
