Ni ubuhe buryo bwa micro vias, impumyi zimpumyi hamwe na vi zashyinguwe mubibaho bya HDI PCB?

Umuyoboro mwinshi cyane (HDI) wanditseho imbaho ​​zumuzunguruko (PCBs) zahinduye inganda za elegitoronike zifasha iterambere ryibikoresho bya elegitoroniki bito, byoroheje, kandi bikora neza.Hamwe na miniaturizasi ikomeza yibikoresho bya elegitoronike, gakondo binyuze mu mwobo ntibikiri bihagije kugirango bikemure ibikenewe bigezweho. Ibi byatumye hakoreshwa microvias, impumyi kandi zishyinguwe mubuyobozi bwa HDI PCB. Muri iyi blog, Capel azareba byimbitse kuri ubu bwoko bwa vias hanyuma aganire ku kamaro kayo mubishushanyo bya HDI PCB.

1. Micropore:

Microholes ni umwobo muto ufite diameter isanzwe ya 0.006 kugeza 0.15 (0.15 kugeza 0.4 mm). Bakunze gukoreshwa muguhuza ibice bya HDI PCBs. Bitandukanye na vias, inyura mubibaho byose, microvias zinyura mubice igice gusa. Ibi bituma habaho ubucucike buri hejuru no gukoresha neza umwanya wibibaho, bigatuma biba ingenzi mugushushanya ibikoresho bya elegitoroniki byoroshye.

Bitewe nubunini bwabo, micropores ifite ibyiza byinshi. Ubwa mbere, bashoboza guhuza ibice byiza nka microprocessor hamwe na chip yo kwibuka, kugabanya uburebure bwumurongo no kunoza ubuziranenge bwibimenyetso. Byongeye kandi, microvias zifasha kugabanya urusaku rwibimenyetso no kunoza ibimenyetso byihuta byerekana ibimenyetso bitanga inzira ngufi. Bagira uruhare kandi mu micungire myiza yubushyuhe, kuko yemerera viasi yumuriro gushyirwa hafi yibice bitanga ubushyuhe.

2. Umwobo uhumye:

Impumyi zihumye zisa na microviya, ariko ziva kumurongo winyuma wa PCB kugeza kumurongo umwe cyangwa nyinshi zimbere muri PCB, zisimbuka ibice bimwe. Iyi vias yitwa "impumyi vias" kuko igaragara gusa kuruhande rumwe. Impumyi zimpumyi zikoreshwa cyane cyane muguhuza urwego rwinyuma rwa PCB hamwe nimbere yimbere. Ugereranije unyuze mu mwobo, irashobora kunoza insinga no kugabanya umubare wibice.

Gukoresha impumyi vias bifite agaciro cyane cyane mubishushanyo mbonera-aho imbogamizi zumwanya ari ngombwa. Mugukuraho ibikenewe byo gucukura umwobo, impumyi zinyuranye zitandukanya ibimenyetso nindege zamashanyarazi, kuzamura uburinganire bwibimenyetso no kugabanya ibibazo bya electromagnetic interineti (EMI). Bafite kandi uruhare runini mukugabanya umubyimba rusange wa HDI PCBs, bityo bikagira uruhare muburyo bworoshye bwibikoresho bya elegitoroniki bigezweho.

3. Umwobo washyinguwe:

Gushyingura vias, nkuko izina ribigaragaza, ni viasi zihishe rwose mubice byimbere bya PCB. Izi vias ntizigera mubice byose byo hanze bityo "zirashyingurwa". Bakunze gukoreshwa mubishushanyo mbonera bya HDI PCB birimo ibice byinshi. Bitandukanye na microviya na viasi zihumye, vi zashyinguwe ntabwo zigaragara kumpande zombi.

Inyungu nyamukuru ya vias yashyinguwe nubushobozi bwo gutanga imiyoboro idakoresheje ibice byo hanze, bigafasha inzira ndende. Mugukuraho umwanya wagaciro kumurongo wo hanze, vias yashyinguwe irashobora kwakira ibindi bice hamwe nibisobanuro, byongera imikorere ya PCB. Zifasha kandi kunoza imicungire yubushyuhe, kuko ubushyuhe bushobora gukwirakwizwa neza binyuze mumbere, aho kwishingikiriza gusa kumashanyarazi kumashanyarazi.

Mu gusoza,micro vias, vias zihumye hamwe na vias zashyinguwe nibintu byingenzi muburyo bwa HDI PCB igishushanyo mbonera kandi gitanga inyungu zinyuranye za miniaturizasi hamwe nibikoresho bya elegitoroniki byuzuye.Microvias ituma inzira yuzuye kandi ikoresha neza umwanya wibibaho, mugihe vias ihumye itanga ihinduka kandi igabanya kubara. Gushyingura vias byongera ubwinshi bwimikorere, kurekura ibice byo hanze kugirango byongere ibice byashyizwe hamwe no gucunga neza ubushyuhe.

Mugihe uruganda rwa elegitoroniki rukomeje gusunika imbibi za miniaturizasi, akamaro kiyi vias mubishushanyo mbonera bya HDI PCB biziyongera gusa. Ba injeniyeri n'abashushanya ibintu bagomba kumva ubushobozi bwabo n'imbogamizi zabo kugirango babikoreshe neza kandi bakore ibikoresho bya elegitoroniki bigezweho byujuje ibyifuzo byikoranabuhanga bigezweho.Shenzhen Capel Technology Co., Ltd ni uruganda rwizewe kandi rwiyemezamirimo rwa HDI rwanditseho imizunguruko. Hamwe nimyaka 15 yuburambe bwumushinga no guhanga udushya mu ikoranabuhanga, barashobora gutanga ibisubizo byujuje ubuziranenge byujuje ibyifuzo byabakiriya. Gukoresha ubumenyi bwa tekiniki yumwuga, ubushobozi bwibikorwa byiterambere, hamwe nibikoresho bigezweho byo gukora hamwe nimashini zipima zitanga ibicuruzwa byizewe kandi bihendutse. Yaba prototyping cyangwa umusaruro mwinshi, itsinda ryabo ryinzobere zinzobere zubuyobozi bwumuzunguruko ryiyemeje gutanga ibisubizo byambere bya tekinoroji ya HDI PCB ibisubizo kumushinga uwo ariwo wose.
