Ikibaho cyumuzingo cyacapwe nikintu gikenewe mubikoresho byinshi byamashanyarazi.PCB yuyu munsi ifite ibice byinshi kuri bo: substrate, traces, mask yo kugurisha, hamwe na silkscreen.Kimwe mu bikoresho byingenzi kuri PCB ni umuringa, kandi hariho impamvu nyinshi zituma umuringa ukoreshwa aho gukoresha andi mavuta nka aluminium cyangwa amabati.
PCBs Yakozwe Niki?
Bivugwa na sosiyete ikoranya PCB, PCBs ikozwe mubintu byitwa substrate, bikozwe muri fiberglass ishimangirwa na epoxy resin.Hejuru ya substrate ni igipande cyumuringa gishobora guhuzwa kumpande zombi cyangwa imwe gusa.Iyo substrate imaze gukorwa, abayikora bayishyiraho ibice.Bakoresha masike yo kugurisha hamwe na silike ya silike hamwe na résistorants, capacator, transistors, diode, chip yumuzunguruko, nibindi bikoresho byihariye.
Kuki umuringa ukoreshwa muri PCB?
Abakora PCB bakoresha umuringa kuko ufite amashanyarazi meza kandi yumuriro.Mugihe amashanyarazi agenda hamwe na PCB, umuringa urinda ubushyuhe kwangiza no gushimangira ahasigaye PCB.Hamwe nandi mavuta - nka aluminium cyangwa amabati - PCB irashobora gushyuha bitaringaniye kandi ntibikora neza.
Umuringa niwo muti watoranijwe kuko ushobora kohereza ibimenyetso byamashanyarazi kuruhande rwose ntakibazo kibuze cyangwa kigabanya umuvuduko w'amashanyarazi.Imikorere yo guhererekanya ubushyuhe ituma abayikora bashira ibyuma bya classique yubushyuhe hejuru.Umuringa ubwawo urakora neza, kuko isima imwe y'umuringa irashobora gupfuka metero kare ya PCB substrate kuri 1.4000th ya santimetero cyangwa micrometero 35 z'ubugari.
Umuringa uyobora cyane kuko ufite electron yubuntu ishobora kugenda kuva kuri atome ikajya mubindi idatinze.Kuberako ikomeza gukora neza kururwo rwego rudasanzwe nkuko ikora kurwego rwinshi, umuringa muto ujya kure.
Umuringa nibindi Byuma Byakoreshejwe Byakoreshejwe muri PCB
Abantu benshi bamenya PCB nkicyatsi.Ariko, mubisanzwe bafite amabara atatu kumurongo winyuma: zahabu, ifeza, numutuku.Bafite kandi umuringa usukuye imbere no hanze ya PCB.Ibindi byuma ku kibaho cyumuzunguruko byerekana amabara atandukanye.Igice cya zahabu nicyo gihenze cyane, igiceri cya feza gifite igiciro cya kabiri-hejuru, naho umutuku nicyo gihenze cyane.
Gukoresha Immersion Zahabu muri PCBs
umuringa ku kibaho cyacapwe
Igice cyometseho zahabu gikoreshwa muguhuza shrapnel hamwe nudupapuro twibigize.Igice cya zahabu yibiza kibaho kugirango wirinde kwimuka kwa atome zo hejuru.Igice ntabwo ari zahabu gusa, ahubwo gikozwe muri zahabu nyayo.Zahabu ni ntoya cyane ariko irahagije kugirango wongere igihe cyibigize bigomba kugurishwa.Zahabu ibuza ibice byabagurisha kwangirika mugihe runaka.
Gukoresha Ifeza ya Immersion muri PCBs
Ifeza nikindi cyuma gikoreshwa mugukora PCB.Birahenze cyane kuruta kwibiza zahabu.Kwibiza muri feza birashobora gukoreshwa mu mwanya wo kwibiza zahabu kuko bifasha no guhuza, kandi bigabanya igiciro rusange cyibibaho.Kwibiza muri silver bikunze gukoreshwa muri PCBs zikoreshwa mumamodoka no kuri mudasobwa.
Umuringa Wambaye Laminate muri PCBs
Aho gukoresha kwibiza, umuringa ukoreshwa muburyo bwambaye.Nuburyo butukura bwa PCB, kandi nicyuma gikoreshwa cyane.PCB ikozwe mu muringa nk'icyuma fatizo, kandi ni ngombwa kubona imirongo ihuza kandi ikavugana neza.
Nigute Umuringa Wumuringa Ukoreshwa muri PCBs?
Umuringa ufite byinshi ukoresha muri PCB, kuva kumuringa wambaye umuringa kugeza kumurongo.Umuringa ningirakamaro kuri PCBs gukora neza.
Ikimenyetso cya PCB ni iki?
Inzira ya PCB nicyo isa, inzira yumuzunguruko ugomba gukurikira.Urutonde rurimo urusobe rw'umuringa, insinga, hamwe na insulasiyo, kimwe na fus n'ibigize bikoreshwa ku kibaho.
Inzira yoroshye yo gusobanukirwa inzira ni ukubitekereza nkumuhanda cyangwa ikiraro.Kugira ngo ibinyabiziga byemerwe, inzira igomba kuba yagutse bihagije kugirango byibuze bibiri muri byo.Igomba kuba mwinshi bihagije kugirango idasenyuka mukibazo.Bakeneye kandi gukorwa mubikoresho bizashobora kwihanganira uburemere bwibinyabiziga bigenda.Ariko, ibimenyetso bikora ibi byose kurwego ruto cyane rwo kwimura amashanyarazi kuruta imodoka.
Ibigize PCB
Hariho ibice byinshi bigize PCB.Bafite imirimo itandukanye igomba gukorwa kugirango inama y'ubutegetsi ikore akazi kayo bihagije.Umuringa ugomba gukoreshwa kugirango ufashe inzira gukora akazi kabo, kandi udafite PCB, ntitwaba dufite ibikoresho byamashanyarazi.Tekereza isi idafite terefone zigendanwa, mudasobwa zigendanwa, abakora ikawa, n'imodoka.Nibyo twagira niba PCBs idakoresheje umuringa.
Ububiko bwa PCB
Igishushanyo cya PCB giterwa n'ubunini bw'inama.Umubyimba uzagira ingaruka ku buringanire kandi uzakomeza ibice.
Ubugari bwa PCB
Ubugari bwibisobanuro nabyo ni ngombwa.Ibi ntabwo bigira ingaruka kuburinganire cyangwa kumugereka wibigize, ariko bikomeza kwimura kurubu bitashyushye cyangwa byangiza ikibaho.
Ikurikiranabikorwa rya PCB
Imiyoboro ya PCB irakenewe kuko aribyo inama y'ubutegetsi ikoresha kugirango yimure amashanyarazi mubice hamwe ninsinga.Umuringa ufasha ibi kubaho, kandi electron yubuntu kuri buri atom ibona icyerekezo kigenda neza kurubaho.
Kuki Umuringa Wumuringa kuri pcbs
Inzira yo Gukora PCB
Inzira yo gukora PCB nimwe.Ibigo bimwe bikora byihuse kurenza ibindi, ariko byose bikoresha inzira imwe nibikoresho.Izi ni intambwe:
Kora umusingi muri fiberglass na resin
Shira umuringa kumurongo
Menya kandi ushireho umuringa
Karaba ikibaho mu bwogero
Ongeramo mask yo kugurisha kugirango urinde PCB
Shyiramo ibara rya silks kuri PCB
Shyira kandi ugurishe abarwanya, imiyoboro ihuriweho, ubushobozi, nibindi bice
Gerageza PCB
PCB igomba kuba ifite ibice byihariye byo gukora neza.Kimwe mu bintu byingenzi bigize PCB ni umuringa.Iyi mavuta irakenewe kugirango ikore amashanyarazi kubikoresho PCB izashyiramo.Hatariho umuringa, ibikoresho ntibikora kuko amashanyarazi ntazaba afite amavuta yo kunyuramo.
