Whether the wire or trace is 10mm long or a mile long the characteristic impedance remains the same provided there is no change in the geometry. Resistance increases as …
Here is a list of electronics and embedded related podcasts. I love listening to these. Its a great way of keeping yourself up to date with the evolving tech. Sometimes …
When you design a PCB, in most EDA tools the designators (R1,C4 U7, etc.) are placed on the silkscreen. Silkscreen layer is for information not data. Sometimes we are so …
When moving up from low speed design to high speed design, I saw engineers trying to length match USB 2.0 within 0.1mm or even closer to zero. Yes, zero skew is the best …
When you design a product and if you are not really sure if you need an extra capacitor for one of the IC or a module. You add it for extra measure and maybe it’s …
Today, I want to talk about two ICs with the same footprint and the same function, yet they may not work interchangeably. The ICs in this discussion are the hex buffer, …
It’s such a small thing to add and yet it’s forgotten. All PCB must have some way of mounting the board inside an enclosure. In cases where the PCB has …
The first thing you should do after importing the net list to your PCB design tool, is to define the rules. The rules definitions actually start at the schematic design …
At some point in your design journey, you will take the leap from designing products around microcontrollers to designing products or projects around microprocessors. …
First of all when I say high speed, it doesn’t mean high frequency, it means quick signal transition. If the trace is longer than the ¼ distance travelled by the signal …
