Relationship between Copper Weight, Trace Width and Current Carrying Capacity
Theoretically, PCB (Printed Circuit Board) current carrying capacity is determined by cross-sectional area of trace and temperature rise. Furtherm...
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...
Precautions for PCB stack-up design for electronic engineers
When designing a PCB (printed circuit board), one of the most basic issues to consider is how many wiring layers, ground planes and power planes ar...
Advantages and disadvantages of several common PCB surface treatment processes and their applicable scenarios
