What is CTI of the PCB base material?

CTI (Comparative Tracking Index), like Tg value, which is one critical property of printed circuit board materials, it is necessary to select a specific PCB laminate material when you start a design a circuit board with special application.

The Difference between IPC-6012, IPC-A-600, and IPC-A-610

IPC-A-600: Acceptance criteria for various types of printed circuit boards. IPC-6012 class 1, 2, 3, manufacturing and performance specifications for rigid printed circuit boards. IPC-A-610 is the criteria guiding the Acceptability of Electronics Assemblies.

What is PCB Trace Impedance and How to Calculate it?

PCB trace impedance is the sum of all the resistance and reactance components of an electrical signal path. An ideal transmission line must have a characteristic impedance that matches both the transmitter and receiver of the intended signal. If the characteristic impedance of the matched transmission line is faithfully maintained, then the full signal sent by the transmitter is seen by the receiver at the end of the trace.
