Umuringa wa fiil kuri PCB

Kubera kongera gukoresha ibikoresho bya elegitoroniki, icyifuzo kuri ibi bikoresho cyahoraga kiri hejuru ku isoko. Ibi bikoresho bidukikije nkuko tubishingikirije kubikorwa bitandukanye. Kubera iyo mpamvu, ndizera ko wahuye nigikoresho cya elegitoroniki cyangwa mubisanzwe ubikoreshe murugo. Niba ukoresheje ibi bikoresho, urashobora kwibaza uburyo ibikoresho byibikoresho bya elegitoronike byatsindira, uko ikora, nuburyo igikoresho gishobora guhuzwa nibindi bintu. Ibikoresho bya elegitoronike dukoresha murugo bikorwa ibikoresho bidakora amashanyarazi. Bafite inzira yatsitswe nibikoresho byunganda bitwara ibicuruzwa hejuru yabo, bigatuma ibimenyetso bitemba mubikoresho mugihe bibaye.

Kubwibyo, ikoranabuhanga rya PCB rishingiye ku gusobanukirwa gukora ibikoresho by'amashanyarazi. PCB ihora ikoreshwa cyane mubikoresho bya elegitoroniki byateguwe kubitangazamakuru. Ariko, mu bisekuru bigezweho, bishyirwa mubikorwa mubikoresho byose bya elegitoroniki. Kubera iyo mpamvu, nta gikoresho cya elegitoronike gishobora gukora nta PCB. Iyi blog yibanze kumuringa wa PCB, hamwe nuruhareUmuringamu nganda z'umuzunguruko.

Ikoranabuhanga ry'umuhanda ryacapwe (PCB)

PCBS ninzira yinzira zitwara amashanyarazi nkakatunga hamwe na tracks, zikaba zikaba zirata hamwe numuringa. Ibi bituma bahuza no gushyigikira ibindi bice bya elegitoroniki bihujwe muburyo bwimikorere. Kubera iyo mpamvu, imikorere nyamukuru yibi bics mubikoresho bya elegitoronike ni ugutanga inkunga mumihanda. Mubihe byinshi, ibikoresho nka fibreglass na plastike byoroshye gufata umuringa mumuzunguruko. Ubusanzwe umuringa muri PCB ubusanzwe irashize hamwe na subremo. Muri PCB, umuringa wumuringa ugira uruhare runini mu kwemerera amashanyarazi hagati yibice bitandukanye byibikoresho, bityo bigashyigikira itumanaho.

Abasirikare bahora bahuze neza hagati ya PCB hamwe nibikoresho bya elegitoroniki. Aba bagurisha bakozwe hakoreshejwe ibyuma bituma babigiramo uruhare; Kubwibyo, barizewe mugutanga inkunga yubukanishi. Ubusanzwe PCB isanzwe ibitswe hamwe nibikoresho byinshi byibikoresho bitandukanye nka silkscreen na flankscreen nibyuma bimaze kumarana na substrate kugirango bibe pcb.

Uruhare rw'umuringa mu nganda z'umuzunguruko

Ikoranabuhanga rishya ryubuhanga muri iki gihe risobanura ko nta gikoresho cya elegitoronike gishobora gukora nta PCB. PCB, kurundi ruhande, shingira kubirenze umuringa kuruta ibindi bice. Ni ukubera ko umuringa ufasha kurema ibimenyetso bifatanya ibice byose muri PCB kugirango wemererwe kwishyurwa mubikoresho. Ibimenyetso birashobora gusobanurwa nkibikoresho byamaraso muri skeleton ya PCB. Kubwibyo PCB ntishobora gukora mugihe ibimenyetso byabuze. Iyo PCB yananiwe gukora, igikoresho cya elegitoroniki kizatakaza igitekerezo cyayo, bigatuma ntacyo bimaze. Kubwibyo, umuringa nibikorwa nyamukuru bigize PCB. Umuringa muri PCB iremeza aho uhora wikiranya nta nkomyi.

Ibikoresho by'umuringa bizwi buri gihe kugirango bigire imyitwarire minini kuruta ibindi bikoresho bitewe na electron yubusa ihari mubikonoshwa byayo. Electron ifite umudendezo wo kwimuka idafite atom umuntu uwo ari we wese uhindura umuringa ushoboye kwishyuza amashanyarazi adafite igihombo cyangwa kwivanga mubimenyetso. Umuringa, uhindura ibintu byiza bya electrolyte, buri gihe bikoreshwa muri PCbs nkikibanza cya mbere. Kuberako umuringa utagira ingaruka ku buso bwa ogisijeni, birashobora gukoreshwa muburyo bwinshi bwa subratesrate, kurisha ibice, n'ibyuma. Iyo ukoreshejwe hamwe nibisohoka, bigizwe nuburyo butandukanye mumuzenguruko, cyane cyane nyuma ya ETCHIng. Ibi byaho bishobotse bitewe nubushobozi bwumuringa kugirango ugire ubumwe bwiza hamwe nibice bikuru bikoreshwa mugukora PCB.

Mubisanzwe hariho ibice bitandatu bya PCB bihimbajwe, hanze yacyo haramwe muri PCB. Ibindi bice bibiri mubisanzwe byongewe kumurongo w'imbere. Kubera iyo mpamvu, ibice byombi ni ugukoresha imbere, hariho kandi bibiri byo gukoresha hanze, hanyuma, bibiri bisigaye mubice bitandatu byose bigomba kuzamura paneli imbere ya PCB.

Umwanzuro

Umuringanikintu cyingenzi cya PCB yemerera gutemba amashanyarazi nta nkomyi. Ifite imyitwarire minini kandi neza neza hamwe nibikoresho bitandukanye byo kwirinda gukoreshwa mubuyobozi bwa PCB. Kubera iyo mpamvu, PCB yishingikiriza kumuringa kugirango ikore nkuko itanga ihuza rya skeleton ya PCB neza.
