Impedance controlled PCBs are commonly used in applications that require high signal integrity, such as high-frequency, radio frequency, or digital signal transmission, such as communication equipment, radio frequency bands, high-speed data transmission, and other fields. Its purpose is to ensure that the signal can be matched with the expected impedance value during transmission on the circuit board, and to minimize signal reflection, crosstalk, and power loss as much as possible.
Impedance is the relative relationship between current and voltage in a circuit. It includes a combination of resistance, inductance, and capacitance, usually represented as a complex number with real and imaginary parts.
In PCBA circuit boards, impedance characteristics refer to the resistance, inductance, and capacitance response of signal transmission lines on the circuit board to high-frequency or high-speed signals. The correct matching of impedance characteristics is crucial for ensuring stable signal transmission, especially in differential signals, high-speed buses, and high-frequency applications.
By precisely controlling the width, spacing, interlayer spacing, material properties, and other parameters of the circuit, the required impedance characteristics can be achieved to ensure accurate signal transmission. This helps reduce signal attenuation, crosstalk, and other circuit issues.
Controlled impedance refers to a specific impedance value that is precisely controlled and maintained on the PCBA circuit board to ensure stable signal transmission. Usually used in high-frequency, high-speed, or differential signal lines.
For specific applications, design engineers will determine the required impedance values, and then manufacturers must precisely control the parameters of the circuit during the PCB manufacturing process to meet these requirements.
Controlled impedance typically involves the use of specific circuit design rules, material selection, and manufacturing processes, such as controlling circuit width, spacing, and interlayer spacing, to ensure the desired impedance value.
In high-frequency and high-speed electronic applications, such as communication devices, high-performance computers, RF circuits, etc., the correct implementation of controlled impedance is crucial because it can reduce signal loss, crosstalk, and timing issues, thereby ensuring the reliability and performance of the circuit.
