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...
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...
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...
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...
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...
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...
