What is the PCB Impedance Control Test Coupons
The PCB impedance test coupon is fabricated at the same time as the main printed circuit boards manufacturing process, so the test coupon will exhibit the same impedance as the PCB performance.

The Importance of Copper Pouring In Copper-Free Areas While Creating PCBs
When electronic engineers create printed circuit boards (PCBs), they tend to leave many copper-free areas on the board. They are probably not aware of the technicalities of the PCB production process. A high percentage of the copper-free area on the board can have a negative impact on the product and leave it susceptible to early damage.
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.

How To Set-up Best Trace Corners in PCB Layout
When an electronic device design finished it’s schematic drawing stage, next phase is to start PCB layout work. So, how to set-up the best track (routing) corners in PCB layout? Which is a better option, 45° corner or rounded corner? Can be layout as 90° corner?
