6 Layer FR4 ENIG Impedance Control PCB
Za The Impedance
Impedance ndi kuphatikiza kwa capacitance ndi inductance kutsekereza kuzungulira mu siginecha yapamwamba kwambiri.Impedance ndi mtundu wa mawonekedwe a AC, zomwe zikutanthauza kuti zimagwirizana ndi pafupipafupi ndipo zimagwiritsidwa ntchito pofotokoza mawonekedwe apamwamba a PCB.
Zinthu Zokhudza Impedans
DK (R):kutsimikiziridwa ndi zopangira (PCB zakuthupi, pepala lochiritsidwa).
Makulidwe a Mzere (T):anatsimikiza ndi zopangira ndi luso ndondomeko.
Kukula kwa Mzere (W):anatsimikiza ndi kasitomala choyambirira kapangidwe ndi luso ndondomeko.
Kunenepa kwapakatikati (H):anatsimikiza ndi kasitomala choyambirira kamangidwe, ndondomeko luso ndi zipangizo.
Choncho, mu kamangidwe ka PCB, tiyenera kulamulira impedance wa mawaya pa bolodi, kuti kupewa chizindikiro kusonyeza ndi kusokoneza maginito maginito ndi mavuto chizindikiro umphumphu momwe tingathere, ndi kuonetsetsa bata la ntchito yeniyeni ya PCB. .
