Umuringa ni iki?

Ibyo bita umuringa gusuka ni ugukoresha umwanya udakoreshwa kuri PCB nkibisobanuro bifatika hanyuma ukuzuza umuringa ukomeye.Uturere twumuringa nabwo twitwa kuzuza umuringa.

Akamaro ko gutwikira umuringa ni ukugabanya inzitizi zinsinga zubutaka no kunoza ubushobozi bwo kurwanya interineti;kugabanya umuvuduko wa voltage no kunoza imikorere yumuriro w'amashanyarazi;niba ihujwe ninsinga zubutaka, irashobora kandi kugabanya umwanya wa loop.

Na none hagamijwe gutuma PCB idahinduka nkibishoboka mugihe cyo kugurisha, benshi mubakora PCB bazakenera kandi abashushanya PCB kuzuza ahantu hafunguye PCB hamwe ninsinga zubutaka zumuringa cyangwa gride.Niba umuringa udafashwe neza, bizashoboka Niba inyungu idakwiriye igihombo, gutwikira umuringa "ibyiza birenze ibibi" cyangwa "ibibi birenze inyungu"?

Buriwese azi ko mugihe cyumuvuduko mwinshi, gukwirakwiza ubushobozi bwinsinga kumurongo wacapwe bizakora.Iyo uburebure burenze 1/20 cyuburebure bujyanye nubunini bwurusaku, ingaruka ya antenne izabaho, kandi urusaku ruzasohoka binyuze mumashanyarazi.Niba hari umuringa udasukuye neza muri PCB, gusuka umuringa biba igikoresho cyo gukwirakwiza urusaku.

Kubwibyo, mumuzunguruko mwinshi, ntutekereze ko insinga zubutaka zahujwe nubutaka ahantu runaka.Indege y'ubutaka ya laminate ni "ubutaka bwiza".Niba umuringa ufashwe neza, umuringa ntiwongera gusa umuyaga, ahubwo unagira uruhare runini rwo gukingira intambamyi.

Uburyo bubiri bwo gutwikira umuringa
Muri rusange hariho uburyo bubiri bwibanze bwo gusuka umuringa, aribwo bunini bunini bw'umuringa no gusya umuringa.Bikunze kubazwa niba ubuso bunini bw'umuringa gusuka ari byiza cyangwa gusuka umuringa wa gride nibyiza.Ntabwo ari byiza kubishyira muri rusange.

Kubera iki?Umwanya munini wumuringa utwikiriye ufite imirimo ibiri yo kongera ibiyobora no gukingira.Ariko, niba ahantu hanini hashyizweho umuringa ukoreshwa mukugurisha imiraba, ikibaho gishobora guterura ndetse n'ibisebe.Kubwibyo, ahantu hanini hashyizweho umuringa, hafunguwe ibinono byinshi kugirango bigabanye igihu cyumuringa.Nkuko bigaragara hano hepfo:

Urusenda rwambaye umuringa rukoreshwa cyane cyane mu gukingira, kandi ingaruka zo kongera amashanyarazi ziragabanuka.Uhereye ku gukwirakwiza ubushyuhe, gride ni nziza (igabanya ubushuhe bwo hejuru bw'umuringa) kandi igira uruhare mu gukingira amashanyarazi mu rugero runaka.Cyane cyane kumuzunguruko nko gukoraho, nkuko bigaragara ku gishushanyo gikurikira:

Byakagombye kwerekanwa ko urusobe rugizwe nibimenyetso byerekanwe.Turabizi ko kumuzunguruko, ubugari bwurugero rufite "uburebure bwamashanyarazi" bujyanye ninshuro yimikorere yumurongo wumuzunguruko (ingano nyayo igabanijwe na Digital frequency ihuye numurongo wakazi irahari, reba ibitabo bijyanye nibisobanuro birambuye ).

Iyo inshuro zakazi zitari hejuru cyane, birashoboka ko uruhare rwumurongo wa gride rutagaragara cyane.Uburebure bw'amashanyarazi bumaze guhuza inshuro zakazi, nibibi cyane.Uzasanga PCB idakora na gato, kandi sisitemu yo kwivanga ikorera ahantu hose.ikimenyetso cya.

Icyifuzo nuguhitamo ukurikije imiterere yakazi yubuyobozi bwabugenewe, ntugafate ku kintu kimwe.Kubwibyo, imirongo myinshi yumuzunguruko ifite byinshi bisabwa kuri gride-intego nyinshi zo kurwanya-kwivanga, kandi umuzenguruko muto ufite umuzenguruko munini hamwe nizindi zikoreshwa cyane zumuringa.
