Ibiranga ibyingenzi byinama yumuriro wacapwe biterwa nibikorwa byubuyobozi bugezweho. Kunoza imikorere ya tekiniki yinama yumuriro wacapwe, imikorere yinama yacapweli yacapwe igomba kunozwa mbere. Kugirango duhuze ibikenewe byiterambere ryinama yumuriro wacapwe, ibikoresho bishya bigenda bitera imbere buhoro buhoro kandi bigakoreshwa.

Mu myaka yashize, Isoko rya PCB ryahinduye kwibanda kuri mudasobwa kugeza itumanaho, harimo na sitasiyo shingiro, seriveri, na terefone igendanwa. Ibikoresho by'itumanaho bya mobile bihagarariwe na terefone igendanwa yatwaye PCBS ku bucucike buhebuje, bworoheje, n'imikorere myinshi. Ikoranabuhanga ryumuzunguruko ryacapwe ntiritandukanya nibikoresho bisimbukiranya, birimo ibisabwa bya tekiniki bya restrate ya PCB. Ibikubiye mubikoresho bikurikirana ubu byateguwe mu ngingo idasanzwe kugirango inganda zivuga.

1 Icyifuzo cyo kwishyurwa-ubwinshi-bwiza

1.1 Gusaba umuringa

PCBs zose ziterambere ryerekeza hejuru-yuzuye kandi zinanutse, kandi imbaho ​​za HDI zigaragara cyane. Imyaka icumi irashize, IPC yasobanuye ikibaho cya HDI nkubugari bwumurongo / umurongo wanditseho (l / s) ya 0.1m / 0.1m na hepfo. Noneho inganda zigera kuri l / s ya 60μm, na l / s ya 40μm. Ubuyapani bwa 2013 verisiyo yo kwishyiriraho tekinoroji yikoranabuhanga ni uko muri 2014, ibisanzwe l / s or orleya 50μm, iterambere l / s hari 20h.

PCB Umuzunguruko Imiterere, imiterere gakondo yimiti (uburyo bwo gukuramo) nyuma yo gufotora kumuringa, imipaka ntarengwa yo gukora imirongo myiza ya 30μm, hamwe na veprine yoroheje. Kubera igiciro kinini cy'umuringa woroheje ccl na net nyinshi mu masarane yoroheje, ingamba nyinshi zitanga imisatsi ya metero 18μm z'umuringa Ubu buryo bufite inzira nyinshi, igenzura ritoroshye, hamwe nigiciro kinini. Nibyiza gukoresha umuringa woroshye. Mubyongeyeho, iyo PCB izamurwa l / s iri munsi ya 20μm, umuringa woroheje muri rusange muri rusange biragoye kubyitwaramo. Birasaba ultra-thin chile file (3 ~ 5μm) substrate na ultra-thing umuringa wometseho kubatwara.

Usibye kuringaniza umuringa, imirongo myiza yubu irasaba gukomera hasi hejuru yumuringa. Mubisanzwe, kugirango utezimbere imbaraga zihuza umuringa hamwe na substrate no kwemeza ko umuyobozi akuramo imbaraga, umuringa wa filire arahungabana. Ubukorikori bw'imiyoboro y'umuringa isanzwe iruta 5μm. Ishimwe ryinshi ry'umuringa rikaze mu mutwe rizamurwanya mu buryo bwo kurwanya inyenzi, ahubwo kugira ngo ugenzure neza insinga zisigaye, bikaroroka kugira imirongo migufi iri hagati y'umurongo cyangwa kugabanuka ku murongo mwiza. Umurongo urakomeye cyane. Kubwibyo, umuringa wumuringa ufite ububi buke (munsi ya 3 μm) ndetse no hasi cyane (1.5 μm) birakenewe.

1.2 Icyifuzo cyamabati atashize

Ikintu cya tekiniki cyinama yubuyobozi bwa HDI nuko inzira yo kubaka (Kwiyubaka burundu), ikoreshwa rya Chepper yakoreshejwe (RCC), cyangwa urwego rwabigenewe rwikirahure cya epoxy nicyo kintu kiragoye kugera kumirongo myiza. Kugeza ubu, uburyo bwongeyeho igice (SAP) cyangwa uburyo bworoshye bwo gutunganya (MSP) bukoreshwa mu gufatanya, hanyuma filime ya electle idafite amatora ikoreshwa mugukora umuyobora uri umuringa. Kuberako urwego rwumuringa rufite ruguru, biroroshye gukora imirongo myiza.

Imwe mu ngingo zingenzi zuburyo bwa kimwe cya kabiri kirimo ibintu byashizeho imirire. Kugirango wuzuze ibisabwa imirongo myiza-yuzuye, ibikoresho bikozweho bishyira imbere ibisabwa byamashanyarazi, ubushishozi, kurwanya ubushyuhe, imbaraga zo guhuza, nibindi. Kugeza ubu, ibikoresho by'itangazamakuru mpuzamahanga byarashize ahanini abf / GX Ibicuruzwa by'Ubuyapani Ajinomoto, bikoresha ibipimo bitandukanye byo kunoza ifu no kugabanya igitambaro cya ONORGANIQ rwo kunoza ifu mu rwego rwo kongera ifumbire. . Hariho kandi ibikoresho bisa na fimicari yoroheje ya Sekisui Compal y'Ubuyapani, kandi ikigo cy'ubushakashatsi bw'inganda za Tayiwani cyateguye kandi ibikoresho nk'ibi. Ibikoresho bya ABF nabyo byakomeje kunozwa kandi bigatera imbere. Igisekuru gishya cyibikoresho byashize bisaba cyane cyane ubuso buke, kwaguka mu bushyuhe, gutakaza imirano, no gukomera gukomeye.

Mu gupakira ku isi hose, icperation ya Spapration yasimbuye gusimbuza ceramic hamwe na stand organic. Ikibuga cyo kuri flip chip (FC) gupakira sportrasiyo igenda iba ntoya kandi nto. Noneho urwego rusanzwe rwamafaranga / umurongo ni 15μm, kandi bizaba bisobanutse mugihe kizaza. Imikorere yabatwara byinshi cyane bisaba ahanini imitima mike yo kwagura ubushyuhe no kurwanya ubushyuhe bwinshi, no gukurikirana ikimenyetso gito gikurikirana hashingiwe ku nama intego zikorwa. Kugeza ubu, umusaruro mwinshi wumuzunguruko mwiza usanga inzira ya MSPA yamenetse yishyurwa hamwe numuringa woroheje. Koresha uburyo bwa SAP kugirango ukore urutonde rwumuzunguruko hamwe na l / s munsi ya 10μm.

Iyo PCBs ibaye denseri kandi inanutse, Ikoranabuhanga rya HDI ryahindutse ikoranabuhanga ririmo intangiriro kugirango ahekeze kugirango ahekenye (ubwo aribwo bwose. Imiyoboro iyo ari yo yose-layer imaze gutabaza hdi ifite imikorere imwe iruta iy'ibanze ikubiyemo imbaho ​​za HDI. Agace no kubyimba birashobora kugabanuka nka 25%. Ibi bigomba gukoresha byoroshye no kubungabunga imitungo myiza yamashanyarazi.

2 inshuro nyinshi no gusaba byihuta

Ikoranabuhanga ryitumanaho rya elegitoronike riva muri wired to Wireless, kuva inshuro nke no kwihuta kurenza inshuro nyinshi n'umuvuduko mwinshi. Imikorere ya terefone igendanwa yinjiye kuri 4G kandi izamuka yerekeza kuri 5G, ni ukuvuga umuvuduko wihuse hamwe nubushobozi bunini bwo kwandura. Gutabaza ibicu bya Global Slow Face byikubye kabiri amakuru, kandi ibikoresho byinshi-byihuta nibikoresho byihuta byimikorere ninzira nyabagendwa. PCB irakwiriye kuvugurura-inshuro nyinshi kandi yihuta-yihuta. Usibye kugabanya ibimenyetso byo kwivanga no gutakaza ibishushanyo mbonera, kubungabunga ubusugire bw'umuzunguruko, no kubungabunga ingwate ya PCB kugirango duhuze ibisabwa, ni ngombwa kugira insimburangingo yo hejuru.

Kugirango ukemure ikibazo cya PCB kongera umuvuduko nubunyangamugayo, abashakashatsi bashushanya cyane cyane kwibanda kumiterere yamashanyarazi. Ibintu by'ingenzi byo guhitamo substrate ni iyumisha ihoraho (dk) nigihombo cyimirire (DF). Iyo dk iri munsi ya 4 na df0.010, ni laminate yo hagati / df iri munsi ya 3.7 na DF0.00

Kugeza ubu, ikunze gukoreshwa mu kibaho cyatsindiye inyuma ya Subcric cyane cyane ni ibisimba bishingiye ku bimera, polyphenylele ether (pPO cyangwa PPE cyangwa PPE) resisiyo za epoxy. Sluorine-ihanga ishingiye ku ngurube, nka polytetrafrouorouoRylenelene (PTFE), gira imitungo yo hasi yubuzima kandi mubisanzwe ikoreshwa hejuru ya 5 ghz. Hariho na epoxy epoxy fr-4 cyangwa ppo.

Usibye resin yavuzwe haruguru nibindi bikoresho byo kwikuramo, hejuru yubuso (umwirondoro) wumuringa nacyo ni ikintu cyingenzi kibangamira igihome cyo kwandura ibimenyetso, bigira ingaruka ku ngaruka zuruhu (skinefce). Ingaruka z'uruhu ni imurwa rya electromagnetic ryakozwe mu nsinga mu gihe cyo kohereza inshuro nyinshi, kandi inductance nini hagati yicyiciro cyinsinga, kugirango ikimenyetso gikunda kwibanda hejuru yinsinga. Ubuso bubi bwumuyobozi bugira ingaruka gutakaza ibimenyetso byo kohereza, kandi gutakaza ubuso bworoshye ni buto.

Ku mirongo imwe, nini nini yubuso bwumuringa, igihombo kinini cyo kwerekana ibimenyetso. Kubwibyo, muburyo nyabwo, turagerageza kugenzura ubunini bwumuringa wumuringa wuzuye ibishoboka byose. Ubukorikori ni gito bushoboka bitabangamiye imbaraga. Cyane kubimenyetso murwego rwo hejuru ya 10 ghz. Kuri 10GHZ, umuringa Fopy Furness agomba kuba munsi ya 1μm, kandi nibyiza gukoresha fopper ya super-player (hejuru yubusa 0.04μm). Ubuso bukabije bwumuringa file igomba guhuzwa nubuvuzi bukwiye bwo kuvura no guhuza isigansi. Mu minsi ya vuba, hazabaho umuringa wa resin-udukoko hamwe nijwi rirenga, rishobora kugira imbaraga zo hejuru kandi ntizagira ingaruka kubushake.
