Flexible printed circuit board (FPC) impedance is a crucial parameter that affects the performance of the circuit. It consists of resistance and reactance, which impede the flow of alternating current. Impedance is denoted by Z and is a complex number comprising a real part (resistance) and an imaginary part (reactance). Capacitive reactance hinders current due to capacitance, while inductive reactance hinders current due to inductance. Collectively, the hindering effects of capacitance and inductance are known as reactance.
The unit of impedance is ohms. In an FPC circuit board with resistance, inductance, and capacitance, impedance plays a critical role in determining how current flows through the circuit. Different types of impedance, such as characteristic impedance, differential impedance, odd mode impedance, even mode impedance, and common mode impedance, must be considered during production.
The Purpose of FPC Impedance
1. When plugging and installing electronic components, it is essential to ensure good conductivity and signal transmission performance. Lower impedance is preferred, with a resistivity lower than 1 ohm:10-6 per square centimeter.
2. Throughout the production process, materials with low resistivity are crucial to maintaining the desired impedance levels and ensuring the circuit board meets quality standards and operates effectively. Production steps must be closely monitored to guarantee the impedance requirements are met.
