Kuvandudza maitiro eakadhindwa redunhu bhodhi (PCB)
Kubva mukutanga kwezana ramakore rechi20, apo nharembozha dzaisundidzira mabhodhi edunhu kuti ave deser, iyorakadhindwa redunhu bhodhi (PCB)indasitiri yanga ichitsvaga madhiri epamusoro kuti asangane nezvinodiwa zvisingagutsikane zvemagetsi madiki, anokurumidza uye akachipa.Maitiro ekuwedzera density haana kuderera zvachose, asi akatowedzera.Nekukwidziridzwa uye kukwidziridzwa kweiyo yakabatanidzwa yedunhu basa gore rega rega, iyo semiconductor indasitiri inotungamira nzira yekuvandudza yePCB tekinoroji, inosimudzira wedunhu bhodhi musika, uye zvakare inomhanyisa maitiro ekusimudzira akadhindwa wedunhu bhodhi (PCB).
Sezvo kuwedzera kwemusanganiswa wedunhu kusanganisa kunotungamira zvakananga kukuwedzera kwekupinza / kubuda (I / O) madoko (mutemo weRent), iyo package inodawo kuwedzera huwandu hwekubatanidza kuti igadzirise chip nyowani.Panguva imwecheteyo, masaizi epasuru anogara achiyedzwa kuti ave madiki.Kubudirira kweiyo planar array yekurongedza tekinoroji kwaita kuti zvikwanise kugadzira anopfuura 2000 anotungamira-kumucheto mapakeji nhasi, uye nhamba iyi ichakura kusvika ingangoita 100000 mukati memakore mashoma sezvo super-Super makomputa anoshanduka.IBM's Blue Gene, semuenzaniso, inobatsira kurongedza huwandu hwakakura hweiyo genetic DNA data.
Iyo PCB inofanirwa kufambirana ne density curve yepakeji uye ichienderana neazvino compact package tekinoroji.Yakananga chip bonding, kana flip chip tekinoroji, inonamira machipi zvakananga kune redunhu bhodhi: nekupfuura yakajairwa kurongedza zvachose.Matambudziko akakura anounzirwa neflip chip tekinoroji kumakambani edunhu redunhu angogadziriswa muchikamu chidiki uye anongogumira kunhamba shoma yemaindasitiri ekushandisa.
PCB mutengesi atozosvika pamiganho mizhinji yekushandisa echinyakare dunhu maitirwo uye anofanirwa kuenderera mberi nekushanduka, sezvaimbotarisirwa, nekudzikira etching maitiro uye kuchera kwemuchina kuri kupikiswa.Indasitiri yedunhu inoshanduka, inowanzoregeredzwa uye kuregeredzwa, yakatungamira maitiro matsva kweanenge makore gumi.Semi-additive conductor fabrication matekiniki zvino anogona kugadzira mhangura yakadhindwa mitsetse isingasviki hupamhi hweImilGSfzm, uye laser drilling inogona kuburitsa mamicroholes e2mil (50Mm) kana mashoma.Hafu yenhamba idzi inogona kuwanikwa mumitsetse midiki yekuvandudza nzira, uye isu tinogona kuona kuti izvi zviri kuitika zvichatengeswa nekukurumidza.
Dzimwe dzenzira idzi dzinoshandiswawo muindasitiri yedhipatimendi yakaoma, asi dzimwe dzacho dzakaoma kuita mundima iyi nekuti zvinhu zvakaita sevacuum deposition hazviwanzo shandiswa muindasitiri yakaoma yedunhu.Mugove wekuchera laser unogona kutarisirwa kuwedzera sezvo kurongedza uye zvemagetsi zvinoda mamwe HDI mabhodhi;Iyo yakasimba yedunhu bhodhi indasitiri ichawedzerawo kushandiswa kwevacuum coating kugadzira yakakwira density semi-yekuwedzera conductor molding.
Pakupedzisira, themultilayer PCB boardmaitiro acharamba achishanduka uye chikamu chemusika che multilayer process chichawedzera.PCB mugadziri achaonawo epoxy polymer system wedunhu mabhodhi anorasikirwa nemusika wavo achifarira mapolymers anogona kushandiswa zvirinani kune laminates.Maitiro acho anogona kukwidziridzwa kana epoxy-ine inodzoreredza moto yakarambidzwa.Isu tinocherekedzawo kuti mabhodhi anochinjika akagadzirisa akawanda ematambudziko ehuremu hwepamusoro, anogona kuchinjirwa kune yakakwira tembiricha isina-alloy maitiro, uye inochinjika yekudzivirira zvinhu haina renje uye zvimwe zvinhu pane zvakatipoteredza "muurayi runyorwa."
Huihe Circuits ikambani yekugadzira PCB, inoshandisa nzira dzakaonda dzekugadzira kuti ive nechokwadi chekuti chigadzirwa chePCB chemutengi wega wega chinogona kutumirwa nenguva kana kusati kwarongwa.Sarudza isu, uye haufanirwe kunetseka nezve zuva rekutumira.
