Nigute ushobora kubona umubare wa pcb
Kubera ko ibice bitandukanye muri PCB byahujwe cyane, mubisanzwe ntabwo byoroshye kubona umubare nyawo, ariko niba witonze witonze amakosa yubuyobozi, urashobora kubitandukanya.
Witonze, tuzasanga hari igice kimwe cyangwa byinshi byibikoresho byera hagati ya PCB.Mubyukuri, iyi ni igikoresho cyo gukingura hagati yurwego kugirango harebwe ko ntakibazo kizunguruka kigufi kiri hagati ya PCB zitandukanye.
Byumvikane ko ikibaho kinini PCB ikoresha ikibaho cyinshi cyangwa impande ebyiri zicyuma, kandi igipande cyiziritse gishyirwa hagati ya buri cyiciro hanyuma kigakanda hamwe.Umubare wibice byubuyobozi bwa PCB byerekana umubare uhari.Icyuma cyigenga cyigenga, hamwe nuburinganire hagati yimirongo byahindutse inzira yimbitse yo kumenya umubare wibice bya PCB.
Uburyo bwo kuyobora umwobo bukoresha "kuyobora umwobo" kuri PCB kugirango umenye umubare wa PCB.Ihame riterwa ahanini nubuhanga bukoreshwa muguhuza umuzenguruko wa PCB nyinshi.Niba dushaka kureba umubare PCB ifite, dushobora gutandukanya turebye binyuze mu mwobo.Ku PCB shingiro (ikibaho cyibanze kimwe), ibice byibanze kuruhande rumwe, naho insinga zegeranijwe kurundi ruhande. Niba ushaka gukoresha ikibaho kinini, ugomba gukubita imyobo kurubaho kugirango pin yibigize ibashe kunyura ku kibaho kurundi ruhande, bityo umwobo windege uzinjira mubibaho PCB, kugirango tubone ko the pin y'ibice bigurishwa kurundi ruhande rwa.
Kurugero, niba ikibaho gikoresha ikibaho cya 4, ugomba guhuza insinga kumurongo wambere nuwa kane (signal signal).Ibindi byiciro bifite ubundi buryo bukoreshwa (hasi yubutaka nimbaraga).Shira ibimenyetso byerekana kumurongo wimbaraga kandi Intego yimpande zombi zubutaka ni ukurinda kwivanga no koroshya gukosora umurongo wibimenyetso.
Niba hari amakarita yubuyobozi yubuyobozi agaragara kuruhande rwimbere yubuyobozi bwa PCB ariko ntushobore kuboneka kuruhande rwinyuma, Ihuriro rya Electronics EDA365 ryizera ko rigomba kuba ikibaho cya 6/8.Niba kimwe binyuze mumyobo gishobora kuboneka kumpande zombi za PCB, mubisanzwe bizaba ikibaho 4.
Nyamara, abakora amakarita menshi yubuyobozi kuri ubu bakoresha ubundi buryo bwo kuyobora, aribwo guhuza imirongo imwe gusa, kandi bagakoresha viasi zashyinguwe hamwe na viasi zimpumyi muri routing.Ibyobo bihumye ni uguhuza ibice byinshi byimbere PCB imbere hejuru ya PCB utinjiye mubibaho byose byumuzunguruko.
Via yashyinguwe ihuza gusa PCB y'imbere, ntabwo rero igaragara hejuru.Kubera ko umwobo uhumye udakeneye kwinjira muri PCB yose, niba ari ibice bitandatu cyangwa birenga, reba ku kibaho kireba isoko yumucyo, kandi urumuri ntiruzanyura.Hariho rero ijambo ryamamaye cyane mbere: urebye ibice bine na bitandatu cyangwa hejuru ya PCB ukurikije niba vias yamenetse.
Hariho impamvu zubu buryo, ariko ntibikurikizwa.Ihuriro rya elegitoroniki EDA365 ryizera ko ubu buryo bushobora gukoreshwa gusa nkuburyo bwo kwifashisha.

Uburyo bwo gukusanya
Mubyukuri, ntabwo aruburyo, ahubwo ni uburambe.Ariko ibi nibyo twibwira ko aribyo.Turashobora gusuzuma umubare wibice bya PCB dukoresheje ibisobanuro byubuyobozi bumwe na bumwe bwa PCB hamwe nibice bigize ibice.Kuberako mubikorwa byikoranabuhanga bya IT bigenda bihinduka vuba, ntababikora benshi bashoboye guhindura PCBs.
Kurugero, mumyaka mike ishize, umubare munini wamakarita yubushushanyo 9550 yateguwe hamwe na PCBs 6.Niba witonze, urashobora kugereranya uburyo bitandukanye na 9600PRO cyangwa 9600XT.Gusa usibye ibice bimwe, kandi ukomeze uburebure bumwe kuri PCB.
Mu myaka ya za 90 yo mu kinyejana gishize, hari ijambo ryamamaye muri kiriya gihe: Umubare wa PCB urashobora kugaragara ushyira PCB neza, kandi abantu benshi barabyizeraga.Aya magambo yaje kugaragara ko ari ubuswa.Nubwo inzira yo gukora icyo gihe yari isubiye inyuma, ni gute ijisho ryashobora kubivuga intera nto kuruta umusatsi?
Nyuma, ubu buryo bwakomeje kandi burahindurwa, buhoro buhoro buhindura ubundi buryo bwo gupima.Muri iki gihe, abantu benshi bizera ko bishoboka gupima umubare wibice bya PCB hamwe nibikoresho bipima neza nka "vernier calipers", kandi ntabwo twemeranya naya magambo.
Utitaye ku kuba hari ubwoko bwibikoresho bisobanutse, kuki tutabona ko PCB igizwe na 12 yikubye inshuro 3 ubugari bwa PCB ya 4?Ihuriro rya EDA365 rya elegitoroniki ryibutsa abantu bose ko PCB zitandukanye zizakoresha inzira zitandukanye zo gukora.Nta gipimo kimwe cyo gupima.Nigute ushobora kumenya umubare wibice ukurikije ubunini?
Mubyukuri, umubare wibice bya PCB bigira uruhare runini kubuyobozi.Kurugero, kuki ukeneye byibura ibice 6 bya PCB kugirango ushyire CPU ebyiri?Kubera iyo mpamvu, PCB irashobora kugira ibimenyetso 3 cyangwa 4 byerekana ibimenyetso, 1 hasi yubutaka, hamwe nimbaraga 1 cyangwa 2.Noneho imirongo yikimenyetso irashobora gutandukana bihagije kugirango igabanye kwivanga, kandi haribintu bihagije bihari.
Nyamara, igishushanyo mbonera cya 4 PCB kirahagije rwose kubibaho rusange, mugihe PCB ya 6-ihenze cyane kandi ntabwo ifite imikorere myiza.
