Ikibaho cyumuzingi-cyerekezo cyerekeranye no gukoresha umurongo mwiza w'ubugari / intera, imyobo ya micro, ubugari bwimpeta (cyangwa nta bugari bwimpeta) hamwe nu mwobo uhishe hamwe nimpumyi kugirango ugere kubwinshi.

Ubusobanuro buhanitse bivuze ko ibisubizo by "byiza, bito, bigufi, kandi binanutse" byanze bikunze biganisha ku bisabwa bisobanutse neza. Fata ubugari bwumurongo nkurugero:

Ubugari bwa 0,20mm, 0.16 ～ 0.24mm yakozwe hakurikijwe amabwiriza yujuje ibyangombwa, kandi ikosa ni (0,20 ± 0.04) mm; mugihe ubugari bwumurongo wa 0,10mm, ikosa ni (0.1 ± 0.02) mm, biragaragara ko ubunyangamugayo bwa nyuma bwiyongereyeho ikintu cya 1, nibindi rero ntabwo bigoye kubyumva, bityo ibisabwa byukuri ntibizaganirwaho ukwe. Ariko nikibazo gikomeye mubuhanga bwo gukora.

Tekinoroji ntoya kandi yuzuye

Mu bihe biri imbere, umurongo-mwinshi w'ubugari / ikibanza kizaba kuva kuri 0.20mm-0.13mm-0.08mm-0.005mm kugira ngo byuzuze ibisabwa na SMT hamwe n’ibipapuro byinshi (Mulitichip Package, MCP). Kubwibyo, tekinoroji ikurikira irakenewe.
UbSubstrate

Ukoresheje umuringa unanutse cyangwa ultra-thin umuringa (<18um) substrate hamwe nubuhanga bwiza bwo kuvura hejuru.
RoIbikorwa

Gukoresha firime yoroheje yumye hamwe no gutondeka neza, firime yoroheje kandi nziza yumye irashobora kugabanya ubugari bwumurongo no kugoreka. Filime itose irashobora kuzuza icyuho gito cyumwuka, kongera interineti ihuza, kandi igateza imbere ubunyangamugayo nukuri.
FilimeElectrodeposited firime

Amashanyarazi yabitswe na Photoresist (ED) arakoreshwa. Umubyimba wacyo urashobora kugenzurwa murwego rwa 5-30 / um, kandi urashobora gutanga insinga nziza cyane. Irakwiriye cyane cyane ubugari bwimpeta, nta bugari bwimpeta na plaque yuzuye amashanyarazi. Kugeza ubu, ku isi hari imirongo irenga icumi itanga umusaruro.
Technology Ikoreshwa rya tekinoroji

Gukoresha tekinoroji ya tekinoroji. Kubera ko urumuri ruringaniye rushobora kunesha ingaruka zubugari bwumurongo uterwa nimirasire ya oblique yumucyo "point" yumucyo, insinga nziza ifite ubugari bwumurongo wuzuye kandi impande zombi zirashobora kuboneka. Nyamara, ibikoresho bisa nkibikoresho birahenze, ishoramari ni ryinshi, kandi birasabwa gukorera ahantu hasukuye cyane.
TechnologyIkoranabuhanga rya optique yo kugenzura

Gukoresha tekinoroji ya optique yo kugenzura. Iri koranabuhanga ryabaye uburyo bwingenzi bwo kumenya mugukora insinga nziza, kandi riratera imbere byihuse, rikoreshwa kandi riratera imbere.

Ihuriro rya elegitoroniki

Ikoranabuhanga rya microporome

Imyobo ikora yimbaho ​​zacapwe zikoreshwa mugushira hejuru ya tekinoroji ya microporome ikoreshwa cyane cyane muguhuza amashanyarazi, bigatuma ikoreshwa rya tekinoroji ya microporome ari ngombwa. Gukoresha ibikoresho bisanzwe byo gucukura hamwe na mashini yo gucukura CNC kugirango ubyare utwobo duto dufite kunanirwa kwinshi nigiciro kinini.

Kubwibyo, ubucucike bwinshi bwibibaho byanditse byibanda cyane cyane ku gutunganya insinga na padi. Nubwo ibisubizo bikomeye byagezweho, ubushobozi bwayo ni buke. Kugirango turusheho kunoza ubucucike (nk'insinga ziri munsi ya 0.08mm), igiciro kirazamuka. , Hindukira rero gukoresha micropores kugirango utezimbere.

Mu myaka yashize, imashini zicukura zumubare hamwe nubuhanga bwa micro-drill byateye intambwe, bityo tekinoroji ya micro-hole yateye imbere byihuse. Nibintu byingenzi byingenzi bigaragara mubikorwa bya PCB.

Mu bihe biri imbere, tekinoroji yo gukora micro-umwobo izashingira cyane cyane kumashini zogucukura za CNC zateye imbere hamwe na microse nziza, kandi umwobo muto wakozwe na tekinoroji ya laser uracyari munsi yuwakozwe n’imashini zicukura CNC ukurikije ibiciro ndetse nubwiza bw’umwobo. .
Imashini yo gucukura

Kugeza ubu, tekinoroji yimashini ya CNC yo gucukura imaze gutera intambwe niterambere. Kandi yashizeho igisekuru gishya cyimashini yo gucukura CNC irangwa no gucukura utwobo duto.

Imikorere yo gucukura umwobo muto (munsi ya 0,50mm) yimashini icukura 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 gucukura 0.1-0.2mm micro-umwobo, ukoresheje ibintu byinshi bya cobalt. Bito-byujuje ubuziranenge bito birashobora gutobora amasahani atatu (1,6mm / blok) ashyizwe hejuru yundi. Iyo imyitozo ya biti yamenetse, irashobora guhita ihagarara ikamenyesha umwanya, igahita isimbuza bito hanyuma ikagenzura diameter (isomero ryibikoresho rishobora gufata ibice amagana), kandi irashobora guhita igenzura intera ihoraho hagati yigitambara nigitwikirizo. n'ubujyakuzimu bwimbitse, bityo imyobo ihumye irashobora gucukurwa, Ntabwo izangiza konte. Imbonerahamwe hejuru yimashini ya dring ya CNC ikoresha uburyo bwo guhumeka ikirere hamwe nubwoko bwa magnetique, bishobora kugenda byihuse, byoroshye kandi byuzuye bitarinze kumeza.

Imashini zogucukura ubu zirasabwa, nka Mega 4600 yo muri Prurite mu Butaliyani, serivise ya Excellon 2000 muri Amerika, hamwe n’ibicuruzwa bishya biva mu Busuwisi no mu Budage.
Gucukura

Hano haribibazo byinshi byimashini zisanzwe za CNC hamwe na bits yo gucukura umwobo muto. Byadindije iterambere rya tekinoroji ya micro-hole, bityo gukuraho lazeri byakwegereye ibitekerezo, ubushakashatsi no kubishyira mubikorwa.

Ariko hariho inenge yica, ni ukuvuga, gushiraho umwobo w'amahembe, bigenda bikomera uko ubunini bw'isahani bwiyongera. Hamwe no kwanduza ubushyuhe bwo hejuru cyane (cyane cyane imbaho ​​nyinshi), ubuzima no kubungabunga isoko yumucyo, gusubiramo ibyobo byangirika, hamwe nigiciro, kuzamura no gukoresha imyobo mito mugukora imbaho ​​zacapwe byarabujijwe . Nyamara, gukuraho lazeri biracyakoreshwa mubisahani bito kandi binini cyane, cyane cyane muri MCM-L ikorana buhanga cyane (HDI), nka firime ya polyester hamwe no gushira ibyuma muri MCMs. (Ikoranabuhanga rya Sputtering) rikoreshwa muguhuza kwinshi kwinshi.

Ishirwaho rya vias yashyinguwe mubucucike bwinshi buhuza imbaho ​​nyinshi zishyinguwe hamwe nimpumyi hakoreshejwe inyubako nazo zirashobora gukoreshwa. Ariko, kubera iterambere niterambere ryikoranabuhanga ryimashini za CNC zicukura na micro-myitozo, zazamuwe vuba kandi zishyirwa mubikorwa. Kubwibyo, ikoreshwa rya laser yo gucukura hejuru yububiko bwumuzingi ntibishobora gukora umwanya wiganje. Ariko iracyafite umwanya murwego runaka.

③Buhanga, buhumyi, kandi binyuze mu mwobo

Gushyingura, guhuma, no guca mu mwobo tekinoroji nayo ni inzira yingenzi yo kongera ubucucike bwumuzingo wacapwe. Mubisanzwe, gushyingurwa no guhuma ni ibyobo bito. Usibye kongera umubare winsinga kurubaho, umwobo ushyinguwe nimpumyi urahuzwa nu gice cyimbere "cyegereye", kigabanya cyane umubare wanyuze mu mwobo wakozwe, kandi gushiraho disiki yo kwigunga nabyo bizagabanuka cyane, bityo byongere umubare wogukoresha neza no guhuza imiyoboro ihuza imbaho, no kunoza imikoranire.

Kubwibyo, ikibaho cyibice byinshi hamwe nuruvange rwashyinguwe, impumyi, hamwe nu mwobo bifite byibuze inshuro 3 hejuru yubucucike bwimikoranire kurenza ibisanzwe byuzuye-byuzuye umwobo munsi yubunini bumwe numubare wabyo. Niba yashyinguwe, impumyi, Ingano yimbaho ​​zacapwe zifatanije nu mwobo zizagabanuka cyane cyangwa umubare wibice uzagabanuka cyane.

Kubwibyo, mubucucike bukabije bwubatswe hejuru yububiko bwanditse, tekinoroji yashyinguwe hamwe nimpumyi zubuhumyi zagiye zikoreshwa cyane, atari mubibaho byanditse hejuru yububiko bwa mudasobwa nini, ibikoresho byitumanaho, nibindi, ariko no mubikorwa bya gisivili ninganda. Yarakoreshejwe kandi mu murima, ndetse no mu mbaho ​​zimwe zoroshye, nka PCMCIA, Smard, amakarita ya IC hamwe n’ibindi bito bitandatu.

Ikibaho cyumuzunguruko cyanditseho imyobo yashyinguwe kandi ihumye muri rusange byuzuzwa nuburyo bwo gukora "sub-board", bivuze ko bigomba kurangizwa hakoreshejwe gukanda inshuro nyinshi, gucukura, no gusiba umwobo, bityo umwanya uhamye ni ngombwa cyane.
