<p>Impedance control is an indispensable aspect of all aspects related to <a href="https://www.atechpcb.com/pcb-manufacturing" rel="noopener noreferrer" target="_blank"><a href="https://www.atechpcb.com/pcb-manufacturing" target="_blank">PCB</a></a>. All stages from design to implementation are necessary. For PCB designers and engineers, neglecting impedance control can be disastrous.</p><p><br></p><p>Understand the basic factors of impedance control</p><p>The connecting wires in the PCB perform multiple functions. In addition to current, they also participate in signal transmission lines. Multifunction helps to maximize the small size and digital output.</p><p><br></p><p>Preventing reflections of signal transmission in the PCB is essential. Impedance control, adjustment and matching impedance can reduce the transmission loss in the circuit. Impedance is a characteristic in AC circuits. It is the resistance provided by the resistance parallel circuit and the power plane for alternating current.</p><p><br></p><p>Various reasons will affect the characteristic impedance of the PCB design. The wrong transmission line can cause many errors.</p><p><br></p><p>The characteristic impedance may also change due to other reasons. Possible factors include:</p><p><br></p><p>1. Circuit trace thickness.</p><p><br></p><p>2. The dielectric value of the prepreg around the circuit trace.</p><p><br></p><p>3. The thickness of the insulator also plays a role.</p><p><br></p><p>As a professional China PCB manufacturer, A-tech has more than 15 years of rich experience in <a href="https://www.atechpcb.com/pcb-manufacturing" rel="noopener noreferrer" target="_blank">PCB manufacturing</a>.
