What are the limitation of circuit implementation using breadboard?
It is heavier. A breadboard is noisier than properly laid-out circuit boards, sometimes far too noisy. It is difficult to troubleshoot due to human error and some poor connections problem. Not good for high current applications.
What are the best breadboards?

What is the disadvantage of using a PCB Why?
Disadvantages of PCB : It contains lead. Thermal shock. Solder bridging. Not easy to repair once damaged.
Why is impedance matching important in high speed PCB design?
If you read a lot of guides on high speed PCB design, you’ll see many mentions to impedance matching. This important process is designed to ensure signals transmit between driver and receiver components without signal reflections and with the required power transmission into the receiving component.
Are there impedance matching schemes for high speed signals?
Impedance matching schemes for single-ended transmission lines. There are many high speed interfaces that use differential signaling. Some of these (e.g., LVDS) have high input impedance, while others have fixed input impedance. Note that some integrated circuits may have on-chip termination (e.g., high pin count LVDS devices).
What should differential impedance be for PCB trace?
Design each trace with slightly larger than 50 Ohms, and design the pair so that the differential impedance is slightly under 100 Ohms. As long as both values are within tolerances, then you are fine.
Why are impedance mismatches important in circuit design?
Because impedance mismatches between components, traces, and vias depend on trace geometry, logic family, and coupling, you need to carefully design traces to have the proper single-ended and differential impedance.
