PCB layout principles and skills sharing
It can be said that pcb wiring is the most important and time-consuming process in the entire PCB design. Here we share some pcb wiring princip...
What does the "false eight layers" mean in the PCB stackup?
Everyone needs to choose a stacking scheme for our board when designing a PCB. A good stacking scheme can make our signal quality better, and the p...
6-layer board design scheme and skills
With the increase of circuit complexity, the design of PCB boards is also developing in the direction of high density and high requirements. T...
What Is the Loop Inductance of a Transmission Line?
Key Takeaways
All transmission lines can be described with a circuit model, where parameters are determined from Maxwell’s equations.
The loop ...
ABSORPTION AND DISPERSION in PCB Interconnects
Reducing signal degradation requires dielectrics with lower Dk and LT, more metal and conductors without rough surfaces.
At a trade show a few year...
Length Matching Routing for PCB Busses
Shortening and folding traces takes creativity and persistence, as long as the timing budget is met.
PRINTED CIRCUIT BOARDS are becoming mo...
