Ten Core Rules for PCB Stackup Design
As high-speed circuits appear more and more, PCB complexity grows. To avoid electrical problems, signal layers and power layers must be separated. This leads to the need for multi-layer PCB design, that is, stackup design. A good stackup design can improve power quality, lower crosstalk and EMI, and improve signal transmission. It can also save […]
Why must a PCB have impedance control?
Introduction In PCB design and manufacturing, impedance control is a critical technical requirement. To understand its necessity, we first clarify the basic concept of impedance and then explore its types, impacts, and practical applications in PCBs. 1. What is impedance? In a circuit that has resistance, inductance, and capacitance, the blocking effect these parts have […]
