Ikibaho cyiza cyane bivuga gukoresha umurongo mwiza w'ubugari / intera, umwobo muto, ubugari bwimpeta (cyangwa ubugari bwimpeta), hamwe nu mwobo washyinguwe nimpumyi kugirango ugere kubwinshi.Kandi ibisobanuro bihanitse bivuze ko ibisubizo bya "binini, bito, bigufi, binini" byanze bikunze bizana ibisabwa byuzuye, fata ubugari bwumurongo nkurugero: O. 20mm ubugari bwumurongo, ukurikije amabwiriza yo kubyara O. 16 ~ 0.24mm yujuje ibisabwa, ikosa ni (O.20 ± 0.04) mm;na O. Kubugari bwumurongo wa 10mm, ikosa ni (0.10 ± 0.02) mm.Biragaragara, ubunyangamugayo bwa nyuma bwikubye kabiri, kandi nibindi ntabwo bigoye kubyumva, bityo ibisabwa-bisobanutse neza ntabwo bizaganirwaho ukundi.Ariko nikibazo gikomeye mubuhanga bwo gukora. 
(1) Ikoranabuhanga ryiza
Kazoza keza cyane ubugari / intera bizahinduka kuva 0,20mm-O.13mm-0.08mm-0.005mm irashobora kuzuza ibisabwa na SMT hamwe na chip-chip nyinshi (Multichip Package, MCP).Kubwibyo, tekinoroji ikurikira irakenewe.
①Gukoresha insina yoroheje cyangwa ultra-thin umuringa (<18um) substrate hamwe nubuhanga bwiza bwo kuvura hejuru. UseGukoresha firime yoroheje yumye hamwe na firime itose, firime yoroheje kandi nziza yumye irashobora kugabanya ubugari bwumurongo kugoreka nudusembwa.Kumurika neza birashobora kuzuza icyuho gito cyumwuka, kongera guhuza imiyoboro, no kunoza ubunyangamugayo nukuri. ③ Ukoresheje amashanyarazi ya electrodepositike (Electro-yabitswe na Photoresist, ED).Umubyimba wacyo urashobora kugenzurwa murwego rwa 5-30 / um, ushobora kubyara insinga nziza cyane, cyane cyane ikwiriye ubugari bwimpeta, nta bugari bwimpeta na electroplating yuzuye.Kugeza ubu, ku isi hari imirongo irenga icumi itanga umusaruro. SingGukoresha tekinoroji igereranya tekinoroji.Kubera ko urumuri ruringaniye rushobora kunesha ingaruka zubugari bwumurongo uterwa nurumuri rudasanzwe rwumucyo "point" urumuri, insinga nziza zifite ubugari bwumurongo utomoye hamwe nimpande zisukuye zirashobora kuboneka.Nyamara, ibikoresho bisa nabyo birahenze, bisaba ishoramari ryinshi, kandi bisaba akazi mubidukikije bifite isuku cyane. ⑤ Kwemeza tekinoroji ya optique yo kugenzura (Automatic Optical Inspection, AOI).Iri koranabuhanga ryabaye uburyo bwingenzi bwo kumenya mugukora insinga nziza, kandi riratera imbere byihuse, rikoreshwa kandi riratera imbere.Kurugero, Isosiyete ya AT&T ifite 11 AoIs, naho} tadco Company ifite 21 AoIs zikoreshwa cyane mugushakisha ibishushanyo byimbere. (2) Ikoranabuhanga rya Microvia
Imyobo ikora yimbaho zacapwe zikoreshwa mugushiraho hejuru cyane cyane bigira uruhare rwumuriro wamashanyarazi, bigatuma ikoreshwa rya tekinoroji ya microvia ari ngombwa.Gukoresha ibikoresho bisanzwe bya drill bit hamwe na CNC yo gucukura kugirango ubyare utwobo duto bifite byinshi binaniranye nibiciro byinshi.Kubwibyo, ubwinshi bwibibaho byacapwe ahanini biterwa no kwagura insinga na padi.Nubwo hari byinshi bimaze kugerwaho, ubushobozi bwayo ni buke.Kugirango urusheho kunoza ubucucike (nk'insinga ziri munsi ya 0.08mm), igiciro cyihutirwa.litiro, bityo uhindukirira gukoresha micropore kugirango utezimbere.
Mu myaka yashize, intambwe imaze guterwa mu mashini ya CNC yo gucukura no mu buhanga bwa micro-drill, bityo ikoranabuhanga rya micro-hole ryateye imbere vuba.Nibintu byingenzi byingenzi bigaragara mubikorwa bya PCB.Mu bihe biri imbere, tekinoroji yo gukora utwobo duto izashingira cyane cyane ku mashini zogucukura za CNC ziteye imbere hamwe n’imitwe mito mito, mu gihe ibyobo byakozwe n’ikoranabuhanga rya laser bikiri munsi y’ibyakozwe n’imashini zicukura CNC duhereye ku biciro no ku bwiza bw’umwobo. . Machine Imashini yo gucukuraCNC Kugeza ubu, tekinoroji yimashini ya CNC ya dring imaze gutera intambwe nshya niterambere.Kandi yashizeho igisekuru gishya cyimashini yo gucukura CNC irangwa no gucukura utwobo duto.Imikorere yo gucukura umwobo muto (munsi ya 0,50mm) na mashini yo gucukura micro-umwobo iruta inshuro 1 ugereranije n’imashini isanzwe ya CNC isanzwe, hamwe no kunanirwa gake, kandi umuvuduko wo kuzunguruka ni 11-15r / min;irashobora gutobora O. 1 ~ 0.2mm micro-umwobo, ubuziranenge bwo mu rwego rwohejuru buto hamwe na cobalt nyinshi zirimo gukoreshwa, kandi amasahani atatu (1.6mm / blok) arashobora gutondekwa kugirango acukure.Iyo imyitozo ya biti ivunitse, irashobora guhita ihagarara ikamenyesha umwanya, igahita isimbuza bito hanyuma ikagenzura diameter (ikinyamakuru cyigikoresho gishobora kwakira ibice amagana), kandi irashobora guhita igenzura intera ihoraho hagati yimyitozo nigitwikirizo. isahani hamwe nubujyakuzimu, bityo umwobo uhumye urashobora gucukurwa., kandi ntizangiza kwangirika.Imashini ya dring ya CNC ikoresha uburyo bwo guhumeka ikirere hamwe na magnetiki ireremba hejuru, bigenda byihuse, byoroshye kandi byuzuye, kandi ntibizashushanya ameza.Imashini nkiyi ya myitozo irabura muri iki gihe, nka Mega 4600 yo muri Prute mu Butaliyani, serivise ya ExcelIon 2000 muri Amerika, hamwe n’ibicuruzwa bishya biva mu Busuwisi no mu Budage. Indeed Hariho ibibazo byinshi bijyanye no gucukura lazeri imashini zisanzwe za CNC hamwe nimyitozo yo gucukura umwobo muto.Byadindije iterambere rya tekinoroji ya micro, bityo gutobora laser umwobo byitabweho, ubushakashatsi no kubishyira mubikorwa.Ariko hariho ibibi byica, ni ukuvuga gushiraho imyobo yamahembe, ikiyongera hamwe no kwiyongera kwububiko bwa plaque.Usibye kwanduza ubushyuhe bwo hejuru (cyane cyane imbaho nyinshi), ubuzima no kubungabunga isoko yumucyo, gusubiramo umwobo wogosha nigiciro, kuzamura no gukoresha imyobo mito mugukora imbaho zacapwe bifite yagarukiye.Nyamara, gukuraho lazeri biracyakoreshwa muri microplate yoroheje kandi yuzuye cyane, cyane cyane mubuhanga buhanitse (HDI) bwa tekinoroji ya MCM-L, nka M. c.Byakoreshejwe muburyo bwo guhuza cyane guhuza firime ya polyester ikarishye muri Madamu hamwe no kubika ibyuma (tekinike ya sputtering).Gushyingurwa hifashishijwe uburyo bwo guhuza imiyoboro myinshi ihuza imbaho nyinshi zishyinguwe hamwe nimpumyi hakoreshejwe inyubako nazo zirashobora gukoreshwa.Ariko, kubera iterambere niterambere ryikoranabuhanga ryimashini zicukura CNC hamwe nuduce duto duto, zazamuwe vuba kandi zishyirwa mubikorwa.Gutyo, lazeri yatoboye umwobo hejuru Porogaramu mu mbaho zumuzunguruko ntizishobora kwiganza.Ariko iracyafite umwanya murwego runaka. TechnologyIkoranabuhanga rirashyinguwe, rihumye kandi rinyuze mu mwobo Ihuriro ry’ikoranabuhanga ryashyinguwe, rihumye kandi rinyuze mu mwobo naryo ni inzira yingenzi yo kuzamura ubwinshi bw’imirongo icapye.Mubisanzwe, gushyingurwa hamwe nimpumyi ni imyenge nto.Usibye kongera umubare wibyuma kurubaho, gushyingura hamwe nimpumyi zihumye zifitanye isano hagati yimbere "yegereye" imbere, ibyo bikaba bigabanya cyane umubare wu mwobo wakozwe, kandi gushiraho disiki yo kwigunga nabyo bizagabanya cyane umubare w. vias.Kugabanuka, bityo kongera umubare wogukora neza hamwe no guhuza imiyoboro ihuza imbaho, no kuzamura ubwinshi bwimikoranire.Kubwibyo, ikibaho cyibice byinshi hamwe nuruvange rwashyinguwe, impumyi kandi runyuze mu mwobo byibuze byibuze inshuro 3 kurenza ibisanzwe byose byanyuze mu mwobo munsi yubunini bumwe numubare wabyo.Ingano yibibaho byacapishijwe hamwe nu mwobo bizagabanuka cyane cyangwa umubare wibice bizagabanuka cyane.Kubwibyo, murwego rwo hejuru rwububiko bwanditseho imbaho zacapwe, zashyinguwe nimpumyi hakoreshejwe ikoranabuhanga ziragenda zikoreshwa, atari mubibaho byanditseho imashini hejuru ya mudasobwa nini, ibikoresho byitumanaho, nibindi, ariko no mubikorwa bya gisivili ninganda.Yarakoreshejwe kandi cyane murwego rwa, ndetse no mubibaho bito, nkibibaho bito bifite ibice birenga bitandatu bya PCMCIA zitandukanye, Smart, IC amakarita, nibindi. Uwiteka icapiro ryumuzingo ryanditseho umwobo ushyinguwe kandi uhumye ibyubatswe byuzuye muburyo bwa "split board" uburyo bwo kubyaza umusaruro, bivuze ko bushobora kurangira gusa nyuma yinshuro nyinshi zo gukanda, gucukura, gusiba umwobo, nibindi, bityo rero umwanya uhamye ni ngombwa cyane..
