Icyiciro Cyose Ubucucike Bwihuza PCB
ICYEMEZO CY'INGENZI CYA HDI
HDI isobanura High Density Interconnector, ni ubwoko bwa PCB bwo gukora (ikoranabuhanga), ikoresha micro impumyi / yashyinguwe hakoreshejwe ikoranabuhanga kugirango tumenye umurongo mwinshi wo gukwirakwiza. Irashobora kugera ku ntera ntoya, imikorere ihanitse hamwe nigiciro gito. HDI PCB nugukurikirana abashushanya, guhora utera imbere ugana ubwinshi kandi bwuzuye. Ibyo bita "hejuru" ntabwo bitezimbere imikorere yimashini gusa, ahubwo binagabanya ubunini bwimashini. Ikoranabuhanga ryinshi rya Density Integrated (HDI) rirashobora gutuma ibicuruzwa byanyuma bishushanya cyane, mugihe byujuje ubuziranenge bwibikorwa bya elegitoroniki kandi neza.
HDI PCB mubisanzwe irimo laser yo gucukura impumyi ikoresheje na mashini yo gucukura impumyi ikoresheje. Tekinoroji yo kuyobora hagati yimbere ninyuma igerwaho mubisanzwe binyuze mubikorwa nko guhamba unyuze, impumyi unyuze, umwobo ushyizwemo, umwobo utigita, umusaraba uhumye / ushyinguwe unyuze, unyuze mu mwobo, impumyi ukoresheje kuzuza amashanyarazi, insinga nziza umwanya muto na mikoro nto muri disiki, n'ibindi.
Hariho ubwoko butandukanye bwa HDI PCB: igipande 1, igipande 2, 3layeri, 4 layer hamwe na layer yose ihuza.
Imiterere yuburyo 1 HDI: 1 + N + 1 (gukanda kabiri, gucukura laser rimwe).
Imiterere yuburyo 2 HDI: 2 + N + 2 (gukanda inshuro 3, gucukura laser kabiri).
Imiterere yuburyo 3 HDI: 3 + N + 3 (kanda inshuro 4, gucukura laser inshuro 3).
Imiterere yuburyo 4 HDI: 4 + N + 4 (kanda inshuro 5, gucukura laser inshuro 4).
Duhereye ku nzego zavuzwe haruguru, dushobora kwemeza ko gucukura lazeri rimwe ari HDI ya 1, kabiri ni HDI 2, nibindi. Igice icyo aricyo cyose Guhuza bishobora gutangira gucukura laser kuva kumurongo wibanze. Muyandi magambo, igikenewe kuba laser yacukuwe mbere yo gukanda nicyiciro cyose HDI.
Igishushanyo mbonera cya HDI
1.Iyo duhuye nigishushanyo gifite umwobo mukarere ka BGA ka PCB igizwe na PCB nyinshi, ariko kubera imbogamizi zumwanya, tugomba gukoresha udukarito duto twa BGA nuduce duto cyane kugirango tugere kubuyobozi bwuzuye, twabikora dute? Noneho turashaka kumenyekanisha HDI yuzuye neza PCB ivugwa kenshi muri PCBs nkibi bikurikira.
Gucukura gakondo kwa PCB bigira ingaruka kubikoresho byo gucukura. Iyo ingano yo gucukura igera kuri 0.15mm, igiciro kimaze kuba kinini cyane kandi biragoye kunoza byinshi. Ariko, kubera umwanya muto, mugihe ingano ya 0.1mm yonyine ishobora kwakirwa, igishushanyo mbonera cya HDI kirakenewe.
2. Gucukura HDI PCB ntikigishingiye ku gucukura imashini gakondo, ahubwo ikoresha tekinoroji yo gucukura laser (rimwe na rimwe bizwi kandi nka laser board). Ingano yo gucukura ya HDI muri rusange ni 3-5mil (0.076-0.127mm), ubugari bwumurongo ni 3-4mil (0.076-0.10mm), ubunini bwibipapuro byabagurisha burashobora kugabanuka cyane, bityo umurongo ushobora kugabanwa urashobora kuboneka kuri agace kamwe, bivamo guhuza cyane.
Kugaragara kw'ikoranabuhanga rya HDI byahinduye kandi biteza imbere iterambere ry'inganda za PCB, bituma BGA nyinshi, QFP, n'ibindi bitunganijwe kuri HDI PCB. Kugeza ubu, ikoranabuhanga rya HDI ryakoreshejwe cyane, muri ryo hakaba harimo 1 HDI yakoreshejwe cyane mu musaruro wa PCB hamwe na 0.5pitch BGA. Iterambere ryikoranabuhanga rya HDI ritera iterambere ryikoranabuhanga rya chip, ariryo ritera iterambere niterambere ryikoranabuhanga rya HDI.
Muri iki gihe, 0.5pitch chip ya BGA yagiye yemerwa buhoro buhoro naba injeniyeri bashushanya, kandi ingingo zigurisha za BGA zagiye zihinduka buhoro buhoro ziva mu kigo gifunguye cyangwa gishyizwe hasi ku buryo bwinjiza ibimenyetso kandi bisohoka mu kigo bisaba insinga.
3. HDI PCB muri rusange ikorwa hakoreshejwe uburyo bwo gutondeka. Inshuro nyinshi gutondeka bikorwa, niko urwego rwa tekinike rwubuyobozi. Ubusanzwe HDI PCB isanzwe yegeranye rimwe, mugihe urwego rwo hejuru HDI rukoresha inshuro ebyiri cyangwa zirenga tekinoroji, hamwe na tekinoroji ya PCB igezweho nko gutobora umwobo, kuzuza umwobo ukoresheje amashanyarazi no gucukura lazeri itaziguye, nibindi.
HDI PCB ifasha gukoresha ikoranabuhanga riteye imbere, kandi imikorere y'amashanyarazi hamwe nibimenyetso byukuri birenze PCB gakondo. Byongeye. HDI ifite iterambere ryiza muguhuza radio inshuro nyinshi, guhuza amashanyarazi ya electronique, gusohora amashanyarazi no gutwara amashyuza, nibindi.
Gusaba
HDI PCB ifite ibintu byinshi byerekana ibintu muburyo bwa elegitoronike, nka:
-Big Data & AI: HDI PCB irashobora kuzamura ubwiza bwibimenyetso, ubuzima bwa bateri no guhuza imikorere o terefone zigendanwa, mugihe bigabanya uburemere nubunini. HDI PCB irashobora kandi gushyigikira iterambere ryikoranabuhanga rishya nkitumanaho rya 5G, AI na IoT, nibindi.
-Imodoka: HDI PCB irashobora kuzuza ibisabwa kandi byizewe bya sisitemu ya elegitoroniki yimodoka, mugihe itezimbere umutekano, ihumure nubwenge bwimodoka. Irashobora kandi gukoreshwa mubikorwa nka radar yimodoka, kugendagenda, kwidagadura no gufasha gutwara.
-Ubuvuzi: HDI PCB irashobora kunoza neza, ibyiyumvo bihamye kandi bihamye nibikoresho byubuvuzi, mugihe bigabanya ubunini bwabyo nogukoresha ingufu. Irashobora kandi gukoreshwa mubice nko gufata amashusho yubuvuzi, gukurikirana, gusuzuma no kuvura.
Porogaramu nyamukuru ya HDI PCB iri muri terefone zigendanwa, kamera ya digitale, AI, abatwara IC, mudasobwa zigendanwa, ibikoresho bya elegitoroniki, robot, drone, nibindi, bikoreshwa cyane mubice byinshi.
