Muri iki gihe, uburyo bugenda bwiyongera bwibicuruzwa bya elegitoronike bisaba igishushanyo mbonera cyibice bitatu byerekana imbaho zicapye.Nyamara, gutondekanya ibice bitera ibibazo bishya bijyanye nuburyo bwo gushushanya.Kimwe mubibazo nukubona ubuziranenge bufite ireme ryubaka umushinga.
Nkuko byinshi kandi bigoye byacapishijwe imirongo igizwe nibice byinshi byakozwe, gutondekanya PCB byabaye ingenzi cyane.
Igishushanyo cyiza cya PCB ningirakamaro kugirango ugabanye imirasire yumuzingi wa PCB hamwe nizunguruka.Ibinyuranye, kwirundanya nabi birashobora kongera cyane imirasire, byangiza biturutse kumutekano.
Ububiko bwa PCB ni iki?
Mbere yuko igishushanyo mbonera cya nyuma kirangira, PCB stackup igizwe na insulator hamwe n'umuringa wa PCB.Gutezimbere gutondeka neza ni inzira igoye.PCB ihuza imbaraga nibimenyetso hagati yibikoresho bifatika, kandi gutondeka neza ibikoresho byubuyobozi bwumuzunguruko bigira ingaruka kumikorere yabyo.
Kuki dukeneye kumurika PCB?
Iterambere rya PCB stackup ningirakamaro mugushushanya imbaho zumuzunguruko.Ububiko bwa PCB bufite inyungu nyinshi, kubera ko imiterere myinshi ishobora guteza imbere ikwirakwizwa ryingufu, ikabuza kwivanga kwa electronique, kugabanya imipaka, no gushyigikira ibimenyetso byihuta.
Nubwo intego nyamukuru yo gutondekanya ari ugushira imiyoboro myinshi ya elegitoronike ku kibaho kimwe unyuze mu byiciro byinshi, imiterere ya PCBs nayo itanga izindi nyungu zingenzi.Izi ngamba zirimo kugabanya intege nke zumuzunguruko w’urusaku rw’urusaku rwo hanze no kugabanya ibibazo byambukiranya imipaka hamwe na sisitemu yo kwihuta.
Ububiko bwiza bwa PCB burashobora kandi gufasha kwemeza ibiciro byumusaruro wanyuma.Mugukoresha neza no kunoza imikorere ya electromagnetic yumushinga wose, gutondekanya PCB birashobora kubika neza igihe namafaranga.
Kwirinda namategeko yo gushushanya PCB laminate
● Umubare w'ibyiciro
Gutondeka byoroshye birashobora gushiramo ibice bine bya PCBs, mugihe imbaho zigoye zisaba lamination yabigize umwuga.Nubwo bigoye cyane, umubare munini wibice byemerera abashushanya kugira umwanya munini utarinze kongera ibyago byo guhura nibisubizo bidashoboka.
Mubisanzwe, umunani cyangwa byinshi birasabwa kugirango ubone uburyo bwiza bwo gutondekanya hamwe nintera kugirango ibikorwa byinshi bigerweho.Gukoresha indege nziza nindege zingufu kubibaho byinshi birashobora kandi kugabanya imirasire.
Aring Gahunda
Itondekanya ryumuringa hamwe nicyuma gikora uruziga bigize imikorere ya PCB.Kugirango wirinde PCB gutwarwa, birakenewe ko igice cyambukiranya ikibaho kiringaniza kandi kiringaniye mugihe cyo gushyira ibice.Kurugero, mubibaho umunani, uburebure bwa kabiri na karindwi bigomba kuba bisa kugirango ugere ku buringanire bwiza.
Ibimenyetso byerekana ibimenyetso bigomba guhora byegeranye nindege, mugihe indege yindege nindege nziza bifatanyirijwe hamwe.Nibyiza gukoresha indege nyinshi zubutaka, kuko muri rusange zigabanya imirasire hamwe nubutaka bwo hasi.
Type Ubwoko bwibikoresho
Ubushyuhe, ubukanishi, n amashanyarazi ya buri substrate nuburyo ikorana ningirakamaro muguhitamo ibikoresho bya PCB laminate.
Ubusanzwe umuzunguruko ugizwe nibirahure bikomeye bya fibre substrate core, itanga ubunini nubukomezi bwa PCB.PCB zimwe zoroshye zishobora kuba zikoze muri plastiki yubushyuhe bwo hejuru.
Igice cyo hejuru ni file yoroheje ikozwe mu muringa wometse ku kibaho.Umuringa ubaho kumpande zombi za PCB impande zombi, kandi ubunini bwumuringa buratandukana ukurikije umubare wibice bya PCB.
Gupfuka hejuru yumuringa wumuringa hamwe na mask yo kugurisha kugirango ibimenyetso byumuringa bihuze nibindi byuma.Ibi bikoresho nibyingenzi kugirango bifashe abakoresha kwirinda kugurisha ahantu heza h'insinga zisimbuka.
Mugaragaza icapiro rya ecran ikoreshwa kumasoko yagurishijwe kugirango yongere ibimenyetso, imibare ninyuguti kugirango byorohereze inteko kandi itume abantu bumva neza ikibaho cyumuzunguruko.
Menya insinga kandi unyuze mu mwobo
Abashushanya bagomba guhuza ibimenyetso byihuta kumurongo wo hagati hagati.Ibi bituma indege yubutaka itanga ingabo ikingira imirase isohoka mumuhanda kumuvuduko mwinshi.
Gushyira urwego rwibimenyetso hafi yurwego rwindege bituma kugaruka kugaruka gutembera mu ndege yegeranye, bityo bikagabanya inzira yo kugaruka.Nta bushobozi buhagije buri hagati yimbaraga zegeranye nindege zubutaka kugirango zitange decoupling iri munsi ya 500 MHz ukoresheje tekinoroji yubwubatsi.
● Gutandukanya ibice
Bitewe nubushobozi bwagabanutse, guhuza cyane hagati yikimenyetso nindege igaruka ni ngombwa.Imbaraga nindege zubutaka nabyo bigomba guhuzwa hamwe.
Ibimenyetso byerekana ibimenyetso bigomba guhora hafi yabyo nubwo byaba biri mu ndege zegeranye.Guhuza hamwe no gutandukanya hagati yingirakamaro ni ngombwa kubimenyetso bidahagarara hamwe nibikorwa rusange.
guteranya
Hano hari ibishushanyo byinshi bitandukanye byububiko bwa PCB muburyo bwa tekinoroji ya PCB.Iyo ibice byinshi birimo, uburyo-butatu bwerekana imiterere yimbere nuburyo bugomba guhuzwa.Hamwe n'umuvuduko mwinshi wo gukora wumuzunguruko ugezweho, igishushanyo mbonera cya PCB kigomba gukorwa kugirango tunoze ubushobozi bwo gukwirakwiza no kugabanya kwivanga.PCB yateguwe nabi irashobora kugabanya kohereza ibimenyetso, gukora, gukwirakwiza amashanyarazi, no kwizerwa kuramba.
