Umuringa wumuringa kuri PCB

Bitewe no gukoresha ibikoresho bya elegitoroniki byiyongereye, ibisabwa kuri ibyo bikoresho byahoraga ari byinshi ku isoko. Ibikoresho ubu biradukikije nkuko tubishingikiriza cyane kubintu bitandukanye. Kubera iyo mpamvu, ndizera ko wahuye nigikoresho cya elegitoroniki cyangwa mubisanzwe ubikoresha murugo. Niba ukoresheje ibyo bikoresho, urashobora kwibaza uburyo ibikoresho bya elegitoroniki bigize insinga, uko ikora, nuburyo igikoresho gishobora guhuzwa nibindi bintu. Ibikoresho bya elegitoronike dukoresha murugo bikozwe mubikoresho bidakoresha amashanyarazi. Bafite inzira zometse kubintu byumuringa uyobora hejuru yabyo, bituma ibimenyetso bitembera mubikoresho mugihe biri gukora.

Kubwibyo, tekinoroji ya PCB ishingiye ku gusobanukirwa imikorere yibikoresho byamashanyarazi. PCB ihora ikoreshwa cyane mubikoresho bya elegitoroniki byagenewe itangazamakuru. Ariko, mubisekuru bigezweho, bishyirwa mubikorwa byose bya elegitoroniki. Kubera iyo mpamvu, nta gikoresho cya elegitoroniki gishobora gukora nta PCB. Iyi blog yibanze kumuringa wumuringa kuri PCB, ninshingano zaumuringamu nganda zumuzunguruko.

Ikoranabuhanga ryacapwe ryumuzunguruko (PCB) Ikoranabuhanga

PCBs ninzira zitwara amashanyarazi nkumurongo n'inzira, zomekwa kumuringa. Ibi bituma bahuza kandi bagashyigikira ibindi bikoresho bya elegitoronike bihujwe nububiko. Kubwiyi mpamvu, imikorere yingenzi ya PCBs mubikoresho bya elegitoronike ni ugutanga inkunga kumuhanda. Kenshi na kenshi, ibikoresho nka fiberglass na plastike bifata byoroshye umuringa wumuringa. Umuringa wumuringa muri PCB mubusanzwe ushyizwemo nubutaka butayobora. Muri PCB, ifiriti y'umuringa igira uruhare runini mu kwemerera amashanyarazi hagati y'ibice bitandukanye bigize igikoresho, bityo agashyigikira itumanaho ryabo.

Abasirikare bahora bahuza neza hagati ya PCB nibikoresho bya elegitoroniki. Aba bagurisha bikozwe hakoreshejwe ibyuma bituma bifata neza; kubwibyo, biringirwa mugutanga ubufasha bwibikoresho kubigize. Inzira ya PCB mubusanzwe ifumbirwa hamwe nibikoresho byinshi nkibikoresho bya silkscreen hamwe nicyuma cyometse kuri substrate kugirango bibe PCB.

Uruhare rwumuringa munganda zumuzunguruko

Ikoranabuhanga rishya rigezweho muri iki gihe bivuze ko nta gikoresho cya elegitoroniki gishobora gukora nta PCB. Ku rundi ruhande, PCB, yishingikiriza cyane ku muringa kuruta ibindi bice. Ni ukubera ko umuringa ufasha gukora ibimenyetso bihuza ibice byose muri PCB kugirango yemererwe gutwarwa mubikoresho. Ibimenyetso bishobora gusobanurwa nkimiyoboro yamaraso muri skeleton ya PCB. Kubwibyo PCB ntishobora gukora mugihe ibimenyetso byabuze. Iyo PCB yananiwe gukora, igikoresho cya elegitoroniki kizatakaza igitekerezo cyacyo, bigatuma kidafite akamaro. Kubwibyo, umuringa nicyo kintu nyamukuru kigizwe na PCB. Umuringa wumuringa muri PCB utuma urujya n'uruza rwibimenyetso nta nkomyi.

Ibikoresho byumuringa bizwi ko bifite umuvuduko mwinshi kuruta ibindi bikoresho bitewe na electroni yubusa igaragara mugikonoshwa cyayo. Electron ifite umudendezo wo kugenda nta kurwanya atom iyo ari yo yose ituma umuringa ushobora gutwara amashanyarazi agenda neza nta gihombo cyangwa kwivanga mu bimenyetso. Umuringa, ukora electrolyte itari nziza, burigihe ukoreshwa muri PCB nkigice cya mbere. Kubera ko umuringa udakunze kwibasirwa na ogisijeni yo hejuru, irashobora gukoreshwa nubwoko butandukanye bwa substrate, izirinda ibice, hamwe nicyuma. Iyo ikoreshejwe hamwe na substrate, ikora imiterere itandukanye muruziga, cyane cyane nyuma yo gutobora. Ibi buri gihe bishoboka bishoboka bitewe nubushobozi bwumuringa bwo gukora umurunga mwiza hamwe na insulente zikoreshwa mugukora PCB.

Mubusanzwe hariho ibice bitandatu bya PCB byahimbwe, muri byo ibice bine biri muri PCB. Ibindi byiciro bibiri mubisanzwe byongewe kumwanya wimbere. Kubwiyi mpamvu, ibice byombi nibikoreshwa imbere, hariho na bibiri byo gukoresha hanze, hanyuma, bibiri bisigaye mubice bitandatu byose ni ukuzamura panne imbere muri PCB.

Umwanzuro

Umuringani igice cyingenzi cya PCB yemerera gutembera kwamashanyarazi nta nkomyi. Ifite imiyoboro ihanitse kandi ikora neza ubumwe bukomeye hamwe nibikoresho bitandukanye byifashishwa mukibaho cyumuzunguruko wa PCB. Kubera iyo mpamvu, PCB yishingikiriza kumuringa wumuringa kugirango ikore kuko ituma ihuza rya skeleton ya PCB rikora neza.
