For power polygon that primarily carry DC, how critical is it that it is located above a ground plane? If it is important, how crucial is it that the polygon completely overlaps the ground plane b...
In my PCB design, I have 0402 components connected to polygons. To reduce the risk of tombstoning, I connected them using thermal relief. My guiding principle is that if heat dissipation is not sy...
My circuit includes the following components: • PIC16 with internal clock, frequency: 32 MHz • ST LED2000 LED driver (a buck converter) with a PWM dimming input. The converter itself isn't a conc...
Hi, I’m working on a PCB layout, which is only about the second board I’ve ever designed. I’d appreciate some help with the following issue: This board has two layers: The top layer is used f...
From what I understand, PCB manufacturing has a limitation on the minimum width of the solder resist—it cannot be too thin, typically not less than 5 mil. In many components, including those with a...
Suppose I use a wide trace as a power rail in my circuit (wide enough for the rated current, at a certain copper weight), and it doesn’t have an adjacent ground plane. If I have enough space on the...
