Nkuko ububiko bwibikoresho bugomba gucunga no kwerekana imisumari ninshini zubwoko butandukanye, ibipimo, ibikoresho, uburebure, ubugari nibibuga, nibindi, igishushanyo cya PCB nacyo gikeneye gucunga ibintu byashushanyije nkibyobo, cyane cyane mubishushanyo mbonera.Ibishushanyo gakondo bya PCB birashobora gukoresha gusa imyenge itandukanye, ariko uyumunsi ibishushanyo mbonera-bihuza (HDI) bisaba ubwoko bwinshi nubunini butandukanye.Buri cyuho kigomba gucungwa kugirango gikoreshwe neza, cyemeza imikorere yubuyobozi ntarengwa kandi ntigikora amakosa.Iyi ngingo izasobanura byinshi ku bijyanye no gucunga ubucucike bukabije binyuze mu mwobo mu gishushanyo cya PCB n'uburyo bwo kubigeraho.

Ibintu bitwara igishushanyo mbonera cya PCB 

Mugihe ibyifuzo byibikoresho bya elegitoronike bikomeje kwiyongera, imbaho ​​zicapye zicapura imbaraga ibyo bikoresho bigomba kugabanuka kugirango bihuze nabyo.Muri icyo gihe, kugirango byuzuze ibisabwa kunoza imikorere, ibikoresho bya elegitoronike bigomba kongeramo ibikoresho byinshi hamwe nizunguruka ku kibaho.Ingano yibikoresho bya PCB ihora igabanuka, kandi umubare wibipapuro uragenda wiyongera, ugomba rero gukoresha pin ntoya hamwe nintera yegeranye kugirango ushushanye, bigatuma ikibazo kitoroshye.Kubashushanya PCB, ibi bihwanye numufuka ugenda uba muto, mugihe urimo ibintu byinshi nibindi.Uburyo gakondo bwibishushanyo mbonera byumuzunguruko bigera kumipaka yabo.

Kugirango uhuze icyifuzo cyo kongeramo imirongo myinshi mubunini buto, uburyo bushya bwo gushushanya PCB bwaje kubaho - Umuyoboro mwinshi wa Interconnect, cyangwa HDI.Igishushanyo cya HDI gikoresha ubuhanga bugezweho bwo gukora imiyoboro yumuzunguruko, ubugari buto bwumurongo, ibikoresho byoroheje, hamwe nimpumyi zishyinguwe cyangwa zashizwemo na lazeri.Bitewe nibi bintu byinshi biranga ubucucike, imirongo myinshi irashobora gushyirwa ku kibaho gito kandi igatanga igisubizo gifatika cyo guhuza imiyoboro myinshi.

Hariho izindi nyungu nyinshi zo gukoresha ibyo byobo byinshi: 

Imiyoboro y'insinga:Kubera ko imyobo ihumye kandi yashyinguwe hamwe na microholes bitinjira mubice, ibi birema imiyoboro yinyongera mugushushanya.Mugushira mubikorwa muburyo butandukanye binyuze mumyobo, abashushanya barashobora gukoresha insinga zifite amajana.Niba gusa ibisanzwe binyuze mu mwobo byakoreshejwe, ibikoresho bifite pin nyinshi mubisanzwe bizahagarika imiyoboro yose yimbere.

Ubunyangamugayo bw'ikimenyetso:Ibimenyetso byinshi kubikoresho bito bya elegitoronike nabyo bifite ibimenyetso byihariye byerekana ubuziranenge, kandi binyuze mu mwobo ntabwo byujuje ibyangombwa bisabwa.Ibi byobo birashobora gukora antene, kumenyekanisha ibibazo bya EMI, cyangwa bigira ingaruka kumuhanda wo kugaruka kumiyoboro ikomeye.Gukoresha ibyobo bihumye no gushyingurwa cyangwa microholes bikuraho ibibazo bishobora kuba ibimenyetso byuburinganire biterwa no gukoresha binyuze mu mwobo.

Kugirango urusheho gusobanukirwa ibi-byobo, reka turebe ubwoko butandukanye bw-ibyobo bishobora gukoreshwa mubishushanyo mbonera-byinshi hamwe nibisabwa.

Ubwoko nimiterere yubucucike buri hagati yimyobo 

Umwobo unyuramo ni umwobo ku kibaho cyumuzunguruko uhuza ibice bibiri cyangwa byinshi.Muri rusange, umwobo wohereza ibimenyetso bitwarwa numuzunguruko kuva kumurongo umwe wibibaho kugeza kumurongo uhuye kurundi rwego.Kugirango ukore ibimenyetso hagati yinsinga, umwobo uba wujujwe mugihe cyo gukora.Ukurikije imikoreshereze yihariye, ubunini bwumwobo na padi biratandukanye.Gitoya binyuze mu mwobo ikoreshwa mugukoresha insinga, mugihe kinini kinini-cyobo gikoreshwa mumashanyarazi hamwe nubutaka, cyangwa kugirango bifashe ubushyuhe bukabije.

Ubwoko butandukanye bwimyobo kurubaho

umwobo

Umuyoboro unyuze niwo musanzwe unyuze mu mwobo wakoreshejwe ku mbaho ​​ebyiri zicapishijwe imizunguruko kuva yatangizwa bwa mbere.Ibyobo byacukuwe mu buryo bwa mashini binyuze mu kibaho cyose cy’umuzunguruko kandi bigizwe n'amashanyarazi.Nyamara, bore ntoya ishobora gucukurwa nu myitozo ya mashini ifite aho igarukira, bitewe nigipimo cyerekeranye na diameter ya drill hamwe nubunini bwa plaque.Muri rusange, aperture yu mwobo ntabwo iri munsi ya 0.15 mm.

Umwobo uhumye:

Kimwe no mu mwobo, ibyobo byacukuwe mu buryo bwa mashini, ariko hamwe nintambwe nyinshi zo gukora, igice cyisahani cyacukuwe hejuru.Ibyobo bihumye nabyo bihura nikibazo cyo kugabanya ingano;Ariko dukurikije uruhande rwibibaho turimo, turashobora insinga hejuru cyangwa munsi yumwobo uhumye.

Umwobo washyinguwe:

Ibyobo byashyinguwe, nkibyobo bihumye, byacukuwe muburyo bwa mashini, ariko tangira kandi birangire murwego rwimbere rwibibaho aho kuba hejuru.Uyu mwobo urasaba kandi izindi ntambwe zo gukora bitewe no gukenera kwinjizwa mu isahani.

Micropore

Uku gutobora kwakuweho na laser kandi aperture iri munsi ya 0.15 mm ntarengwa ya biti ya mashini.Kuberako microholes ifite ibice bibiri byegeranye gusa byubuyobozi, igipimo cya aspect gituma ibyobo biboneka kubisahani bito cyane.Microholes irashobora kandi gushirwa hejuru cyangwa imbere yikibaho.Microholes isanzwe yuzuzwa kandi igashyirwaho, cyane cyane ihishe, bityo irashobora gushyirwa mubutaka-bugurisha ibintu bigurisha imipira yibigize nka ball grid array (BGA).Bitewe na aperture ntoya, padi isabwa kuri microhole nayo ni nto cyane kurenza umwobo usanzwe, hafi mm 0.300.

Ukurikije igishushanyo mbonera gisabwa, ubwoko butandukanye bwibyobo byavuzwe haruguru birashobora gushyirwaho kugirango bikore hamwe.Kurugero, micropore irashobora gutondekwa hamwe nizindi micropore, kimwe nu mwobo washyinguwe.Ibyo byobo birashobora kandi gutangara.Nkuko byavuzwe haruguru, microholes irashobora gushirwa mumapadiri hamwe nubuso bwibikoresho.Ikibazo cyo guhuza insinga kirushijeho kugabanuka no kubura inzira ya gakondo kuva hejuru yimisozi igana ku bafana.
