10 Layer ENIG FR4 Impedance Control PCB
Chifukwa Chiyani Kuwongolera Kusokoneza Pa PCBs?
Pamene chizindikiro chimafuna cholepheretsa kuti chizigwira ntchito bwino, cholepheretsa choyendetsedwa chiyenera kukondedwa.M'mapulogalamu apamwamba kwambiri, bolodi lamagetsi lathunthu lokhala ndi vuto losalekeza ndilofunika kuti ateteze deta yopatsirana ku ziphuphu ndi kusunga zizindikiro zomveka bwino.Kutalikira kwa njira kapena kukwezera pafupipafupi, kusinthasintha kumafunikanso.Kupanda kukhwima kulikonse panthawiyi kumatha kuwonjezera nthawi yosinthira zida zamagetsi kapena mabwalo ndikupangitsa zolakwika zosayembekezereka.
Chigawocho chikayikidwa pa dera, kusokoneza kosalamulirika kumakhala kovuta kusanthula.Magawo ali ndi kuthekera kosiyana kolekerera kutengera gulu lawo.Kuonjezera apo, zizindikiro zawo zimakhala ndi kusintha kwa kutentha, zomwe zingayambitse kulephera.Pankhaniyi, kusintha chigawocho kungawoneke ngati yankho poyamba, koma kwenikweni, kulepheretsa kufufuza kosayenera ndizomwe zimayambitsa vutoli.
Ichi ndichifukwa chake kufufuza kwa impedance ndi kulolerana kwake kuyenera kufufuzidwa koyambirirabolodi losindikizidwa (PCB)kupanga.Wopangayo ayenera kugwira ntchito limodzi ndi wopanga kuti atsimikizire kuti phindu la gawolo likukwaniritsidwa.
Makhalidwe a Impedans a PCB
PCB kutsatira impedance ili ndi mikhalidwe ingapo yophunzirira impedance.PCB board board impedance imaphatikizapo: chilolezo, kutalika, m'lifupi, kutalika, malire opanga PCB / kulolerana, ndi mawonekedwe amtunda pakati pa njanji ndi mkuwa wina.
Mapulogalamu a Impedance Control PCB
Kuwongolera kwa Impedans kumaphatikizapo kuyeza kutsekeka kwa njira zina zopangira ma board ndikuwonetsetsa kuti zili m'malire operekedwa ndi wopanga.Njirayi ndi yokwera mtengo, koma yakhala yovomerezeka ndi anthu kuyambira kumayambiriro kwa zaka za m'ma 2000 pamene mafupipafupi a zigawo zamagetsi akupitiriza kuwonjezeka.Mwachitsanzo, gwiritsani ntchito pazinthu zotsatirazi:
Analogi ndi digito telecommunication
Kukonza chizindikiro chamavidiyo
bokosi la intaneti, TV, GPS, masewera apakanema, kamera ya digito
Makompyuta, mapiritsi, mafoni
Motor control module
