1.Amashurwe.

1: Umwobo wo gukosora ugomba kuba udafite ibyuma.Mugihe cyo kugurisha umuraba, niba umwobo utunganya ari umwobo wicyuma, amabati azahagarika umwobo mugihe cyo kugurisha.

2. Gukosora umwobo wo gushiraho nka padi ya quincunx ikoreshwa muburyo bwo gushiraho umwobo wa GND, kuko muri rusange umuringa wa PCB ukoreshwa mu gushyira umuringa kuri neti ya GND.Nyuma ya cincunx imyobo yashizwemo nibice bya PCB shell, mubyukuri, GND ihujwe nisi.Rimwe na rimwe, igikonoshwa cya PCB gifite uruhare rwo gukingira.Birumvikana ko bamwe badakeneye guhuza umwobo uzamuka kumurongo wa GND.

3. Umwobo wicyuma urashobora gukubitwa, bikavamo imipaka ya zeru yo guhagarara no kudahagarara, bigatuma sisitemu iba idasanzwe.Umwobo wururabyo, nubwo uko imihangayiko ihinduka, irashobora guhora igumye hasi.

2. Kwambuka indabyo.

Amashurwe yindabyo kandi yitwa padi yumuriro, umuyaga ushushe, nibindi. Igikorwa cyayo nukugabanya kugabanuka kwubushyuhe bwa padi mugihe cyo kugurisha, kugirango hirindwe kugurishwa kwinshi cyangwa gukuramo PCB biterwa no gukwirakwiza ubushyuhe bukabije.

1 Iyo padi yawe iri hasi.Igishushanyo mbonera gishobora kugabanya ubuso bwinsinga zubutaka, kugabanya umuvuduko wo gukwirakwiza ubushyuhe, no koroshya gusudira.

2 Iyo PCB yawe isaba gushyira imashini hamwe nimashini igurisha, padi yambukiranya imipaka irashobora kubuza PCB gukuramo (kuko hakenewe ubushyuhe bwinshi kugirango ushongeshe paste)

3. amarira

Amosozi ni amasano arenze urugero hagati ya padi ninsinga cyangwa insinga hamwe na.Intego ya marira ni ukwirinda aho uhurira hagati yinsinga na padi cyangwa insinga hamwe ninzira iyo ikibaho cyumuzunguruko gikubiswe nimbaraga nini zo hanze.Guhagarika, wongeyeho, gushiraho amarira birashobora kandi gutuma ikibaho cyumuzunguruko cya PCB gisa neza.

Igikorwa cyamarira ni ukwirinda kugabanuka gutunguranye kwubugari bwumurongo wikimenyetso no gutera gutekereza, bishobora gutuma ihuriro riri hagati yikurikiranabikorwa hamwe nibice bigize ibice biba inzibacyuho yoroshye, kandi bigakemura ikibazo ko isano iri hagati ya padi na tronc ari kumeneka byoroshye.

1. Iyo kugurisha, birashobora kurinda padi no kwirinda kugwa kuri padi kubera kugurisha byinshi.

2. Shimangira ubwizerwe bwihuza (umusaruro urashobora kwirinda gutobora kutaringaniye, ibice biterwa no gutandukana, nibindi)

3. Impedance yoroshye, gabanya gusimbuka gukabije kwa impedance

Mu gishushanyo mbonera cy’umuzunguruko, kugira ngo padi ikomere kandi ikumire padi ninsinga bidacika mugihe cyo gukora imashini yubukanishi, firime yumuringa ikoreshwa kenshi mugutegura inzibacyuho hagati ya padi ninsinga , ikaba imeze nk'amarira, bityo ikunze kwitwa Amarira (Amarira)

4. ibikoresho byo gusohora

Wigeze ubona abandi bahinduranya ibikoresho byabigenewe babigambiriye kubushake bwumuringa wambaye umuringa munsi yuburyo busanzwe bwa inductance?Ni izihe ngaruka zihariye?

Ibi byitwa iryinyo risohora, icyuho cyo gusohora cyangwa icyuho.

Ikinyuranyo cya spark ni jambo ya mpandeshatu ifite inguni zikarishye zerekanana.Intera ntarengwa hagati yintoki ni 10mil naho byibuze ni 6mil.Delta imwe irahagaze, indi ihujwe numurongo wibimenyetso.Iyi mpandeshatu ntabwo igizwe, ariko ikozwe mugukoresha umuringa wumuringa muburyo bwa PCB.Izi mpandeshatu zigomba gushyirwaho kumurongo wo hejuru wa PCB (ibice) kandi ntizishobora gutwikirwa na masike yagurishijwe.

Mugihe cyo guhinduranya amashanyarazi yatanzwe cyangwa ikizamini cya ESD, voltage nini izabyara kumpande zombi zuburyo busanzwe bwa inductor kandi arcing izaba.Niba ari hafi yibikoresho bikikije, ibikoresho bikikije bishobora kwangirika.Kubwibyo, umuyoboro usohora cyangwa varistor urashobora guhuzwa muburyo bwo kugabanya ingufu zayo, bityo bikagira uruhare mukuzimya arc.

Ingaruka zo gushyira ibikoresho birinda inkuba nibyiza cyane, ariko ikiguzi ni kinini.Ubundi buryo ni ukongeramo amenyo asohoka kumpande zombi zuburyo busanzwe bwa inductor mugihe cyogushushanya kwa PCB, kugirango inductor isohoka binyuze mumpanuro abiri yo gusohora, wirinde gusohora binyuze munzira zindi, kugirango ibizengurutse Kandi ingaruka zibikoresho byanyuma bizagabanuka.

Icyuho cyo gusohora ntigisaba amafaranga yinyongera.Irashobora gushushanya mugihe ushushanya ikibaho cya pcb, ariko ni ngombwa kumenya ko ubu bwoko bwikinyuranyo cyo gusohora ari icyuho cyo mu kirere cyo mu kirere, gishobora gukoreshwa gusa mubidukikije aho ESD ikorwa rimwe na rimwe.Niba ikoreshejwe mugihe aho ESD iboneka kenshi, ububiko bwa karubone buzabyara kumpande ebyiri zimpande eshatu hagati yicyuho cyo gusohora bitewe no gusohora kenshi, amaherezo bizatera umuzunguruko mugufi mu cyuho cyo gusohora kandi bigatera umurongo uhoraho wa signal umurongo kugeza hasi.Ibisubizo muburyo bwa sisitemu.
