Why choose Multilayer PCB?
Multilayer PCBs are chosen because they allow more circuitry to be accommodated in a smaller space, providing higher performance and lower electromagnetic interference. This design also makes the signal transmission path shorter, helping to reduce signal distortion.
Multilayer PCB is commonly used in complex electronic equipment, such as communication equipment, computer systems, medical equipment, military applications and other fields that require strict requirements for highly integrated circuits and electromagnetic compatibility.
