Nkuko amaduka yimyandikire akeneye gucunga no kwerekana imisumari n'imigozi yubwoko butandukanye, ibipimo, ibikoresho, uburebure, ibishushanyo, ibishushanyo, ibishusho, nibindi bikenewe. Ibishushanyo gakondo bya PCB birashobora gukoresha gusa umwobo nkeya utandukanye, ariko uyumunsi uhuza cyane (HDI) bisaba ubwoko bwinshi nubunini bwimikono myinshi. Buri mwobo ukwiye kunga gukoreshwa neza, kubungabunga imikorere ntarengwa yinama hamwe nubusa. Iyi ngingo izasobanura neza ko ari ngombwa gucunga cyane binyuze mu mwobo mu gishushanyo mbonera cya PCB nuburyo bwo kubigeraho.

Ibintu bitwara ibishushanyo mbonera bya PCB 

Mugihe ibyifuzo bya elegitoroniki nto ya elegitoronike bikomeje kwiyongera, imbaho ​​yumuriro wacapwe iha agaciro ibi bikoresho bigomba kugabanuka kugirango bikwiranye nabo. Muri icyo gihe, kugirango bahuze ibisabwa mu buryo bwo guteza imbere imikorere, ibikoresho bya elegitoroniki bigomba kongeramo ibikoresho byinshi n'imizunguruko. Ingano y'ibikoresho bya PCB buri gihe iragabanuka, kandi umubare w'ikipimbo uriyongera, ugomba rero gukoresha amapine mato no gufata neza gushushanya, bituma ikibazo kigora. Ku bashushanya PCB, ibi bihwanye numufuka ugenda utukura kandi bito, mugihe ufashe ibintu byinshi kandi byinshi. Uburyo gakondo bwo gushushanya umuzunguruko bigera ku mipaka yabo.

Kugirango uhuze ibikenewe wo kongeramo imirongo myinshi mubunini bwinama yubuyobozi, uburyo bushya bwa PCB bwabaye - guhuza-ubucucike, cyangwa HDI. Igishushanyo cya HDI gikoresha uburyo bwambere bwumuzunguruko wubuyobozi bwinama yubuyobozi, ubugari buto, ibikoresho byoroheje, nimpumyi kandi bihumye cyangwa imibura ya laser cyangwa laser. Urakoze kubiranga ubucucike bwimbitse, imirongo myinshi irashobora gushyirwa mubijyanye nigice gito kandi itange igisubizo kidafite ishingiro kumurongo wimigabane myinshi ihuriweho.

Hariho izindi nyungu nyinshi zo gukoresha ibyo byobo byo hejuru: 

Imiyoboro yinyoni:Kubera ko ari impumyi kandi zishyingurwa na microholes ntizinjira mu kibaya, ibi bitera imiyoboro yinyongera yinyoni mubikorwa. Mugushira neza ibi binyura mu mwobo, abashushanya barashobora kwibisha ibikoresho bifite amapine amagana. Iyaba urwego rwibipimo rukoreshwa, ibikoresho hamwe nibiciro byinshi bizabuza imiyoboro yose yimbere.

Ubunyangamugayo bw'Ikimenyetso:Ibimenyetso byinshi ku bikoresho bito bya elegitoronike nabyo bifite ibisabwa mubunyangamugayo bwihariye, kandi binyuze mu mwobo ntabwo byujuje ibisabwa. Izi mwobo zirashobora gukora antene, utangire ibibazo bya EMI, cyangwa bigira ingaruka kubimenyetso byo kugaruka kumiyoboro ikomeye. Gukoresha umwobo wimpumye kandi washyinguwe cyangwa microholes ikuraho ibibazo byubusa byubunyangamugayo byatewe no gukoresha uko umwobo.

Kugira ngo usobanukirwe neza ibi binyuze mu mwobo, reka turebe ubwoko butandukanye bwinzoka zishobora gukoreshwa mubusa-bwinkunga no gusaba.

Andika nuburyo bwo guhuza imiyoboro myinshi 

Umwobo wa pass ni umwobo ku kibaho cyumuzunguruko gihuza ibice bibiri cyangwa byinshi. Muri rusange, umwobo uhindura ikimenyetso cyatwarwa numuzunguruko kuva kumurongo umwe winama yinama kugeza ku muzunguruko uhuye kurundi rwego. Kugirango wigane ibimenyetso hagati yibisimba biyifite, ibyobo byahuye mugihe cyo gukora. Ukurikije uburyo bwihariye, ubunini bwumwobo na padi biratandukanye. Gitoya unyuze mu mwobo ukoreshwa mubyiciro, mugihe kinini unyuze mu mwobo ukoreshwa kubutegetsi nubutaka, cyangwa gufasha ubushyuhe ibikoresho byinshi.

Ubwoko butandukanye bwinzobere ku kibaho cyumuzunguruko

unyuze

Unyuze mu mwobo nubusanzwe binyuze-umwobo wakoreshejwe ku kibaho cyinshi cyacapwe imbaho ​​zumuzunguruko kuva zaramenyeshejwe bwa mbere. Ibyobo byacukuwe muburyo bwumuzunguruko wose kandi ni amashanyarazi. Ariko, byibuze ibyakundwa nimyumikorere ifite aho igarukira, bitewe nubutaka bwo gutwara imperuka kuri plaque ubunini. Muri rusange, aperture ya unyuze mu mwobo ntabwo ari munsi ya 0.15.

Umwobo uhumye:

Kimwe no mu mwobo, ibyobo byacukuwe muri mashini, ariko hamwe n'intambwe nyinshi zo gukora, igice cy'isahani gusa gicukurwa ku buso. Imyuka ihumye nayo ihura nikibazo cyimipaka itangizwa; Ariko ukurikije uruhande rwinama turimo, dushobora kwiyibutsa hejuru cyangwa munsi yumwobo wimpumyi.

Ubworere bwashyinguwe:

Yashyinguwe umwobo, nk'inzoga zimpumyi, yacukuwe muri mashini, ariko itangira kandi irangira mu kibaho cy'imbere cy'ubuyobozi aho kuba ubuso. Ibi binyuze-umwobo usaba kandi intambwe zinyongera ziterwa no gukenera kwinjizwa mu isahani.

MicroPere

Iyi moteri ishimezwa na laser kandi aperture iri munsi ya 0.15 mm ntarengwa ya robine bit. Kuberako microhoiles ikoresha ibice bibiri gusa byinama, igipimo cyihariye gituma umwobo uboneka muguhitamo cyane. Microhole irashobora kandi gushyirwa hejuru cyangwa imbere yinama. Microholes ubusanzwe yuzuye kandi ihishe, ihishe rero, kandi irashobora gushyirwa mumipira yumusozi wamaguru yingingo nka ball grid arrays (BGA). Bitewe na aperture ntoya, padi isabwa kuri microhole nayo ni nto cyane kuruta umwobo usanzwe, hafi mm .300.

Ukurikije ibisabwa, ubwoko butandukanye bwinzobere burashobora gushyirwaho kugirango bakore hamwe. Kurugero, Micropores irashobora gutondekwa hamwe nabandi micropores, kimwe no ku mwobo washyinguwe. Izi mwobo nayo irashobora gutangara. Nkuko byavuzwe haruguru, Microhole irashobora gushyirwa mumapaji hamwe nimisozi miremire. Ikibazo cyo kwivuza cyiyongera kirakomeza kugirango hatabaho inzira gakondo kuva hejuru yumusozi wa Pad kumufana.
