Ubusobanuro buhanitse bwibibaho byumuzunguruko bivuga gukoresha umurongo mwiza wubugari / intera, imyobo ya micro, ubugari bwimpeta (cyangwa ubugari bwimpeta), hamwe nu mwobo uhishe hamwe nimpumyi kugirango ugere kubwinshi.
Ubusobanuro buhanitse bwerekeza ku bisubizo bya "binini, bito, bigufi, binini" byanze bikunze bizana ibisabwa byuzuye, bifata ubugari bwumurongo nkurugero: ubugari bwumurongo wa 0,20mm, ukurikije amabwiriza yo gutanga 0.16 ~ 0.24mm nkuko byujuje ibisabwa, ikosa ni (0,20 ± 0.04) mm; n'ubugari bwumurongo wa 0,10 mm, ikosa ni (0.1 ± 0.02) mm muburyo bumwe. Biragaragara ko ubunyangamugayo bwa kabiri bwikubye kabiri, kandi nibindi ntabwo bigoye kubyumva, kubwibyo bisabwa bisobanutse Ntibikiri kuganirwaho ukundi, ariko nikibazo gikomeye mubuhanga bwikoranabuhanga.
1.Ikoranabuhanga ryiza
Mugihe kizaza, uburebure bwumurongo muremure / intera bizaba kuva kuri 0.20mm kugeza 0.13mm kugeza 0.08mm kugeza 0.005mm kugirango byuzuze ibisabwa na SMT hamwe na chip nyinshi (Mulitichip Package, MCP). Kubwibyo, tekinoroji ikurikira irakenewe:
①Gukoresha insina yoroheje cyangwa ultra-thin umuringa (<18um) substrate hamwe nubuhanga bwiza bwo kuvura hejuru.
② Gukoresha firime yoroheje yumye hamwe na lamination itose, 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.
③Electrodeposited Photoresist (ED) irakoreshwa. Umubyimba wacyo urashobora kugenzurwa murwego rwa 5 ~ 30 / um, ushobora kubyara insinga nziza cyane. Irakwiriye cyane cyane ubugari bwimpeta, nta bugari bwimpeta hamwe nisahani yuzuye. Kugeza ubu, ku isi hari imirongo irenga icumi itanga umusaruro.
DKwemeza tekinoroji ya tekinoroji. Kubera ko urumuri ruringaniye rushobora gutsinda ingaruka zubugari bwumurongo uterwa nurumuri rudasanzwe rwumucyo wa "point" urumuri, insinga nziza ifite ubugari bwumurongo nukuri kandi irashobora kuboneka. Nyamara, ibikoresho bisa nkibikoresho birahenze, bisaba ishoramari ryinshi, kandi bisaba gukorera ahantu hasukuye cyane.
DKwemeza tekinoroji ya optique yo gutahura. Iri koranabuhanga ryabaye uburyo bwingenzi bwo gutahura mugukora insinga nziza kandi riratera imbere byihuse, rikoreshwa kandi riratera imbere.
2.Ikoranabuhanga rya micropore
Imyobo ikora yibibaho byanditseho imbaho zacapwe zikoreshwa cyane cyane muguhuza amashanyarazi, bigatuma ikoreshwa rya tekinoroji ya micro-umwobo ari ngombwa. Gukoresha ibikoresho bisanzwe bya drill bit hamwe na CNC imashini zogucukura kugirango zibyare utwobo duto bifite kunanirwa kandi nigiciro kinini.
Kubwibyo, ubucucike bwinshi bwanditseho imbaho zumuzingi ahanini bikozwe ninsinga nziza. Nubwo ibisubizo bikomeye byagezweho, ubushobozi bwabo ni buke. Kugirango turusheho kunoza ubucucike (nk'insinga ziri munsi ya 0.08 mm), igiciro cyazamutse cyane Kubwibyo, micro-pores ikoreshwa mugutezimbere.
Mu myaka yashize, intambwe imaze guterwa mu ikoranabuhanga ry’imashini zicukura CNC na micro-bits, bityo ikoranabuhanga rya micro-umwobo ryateye imbere byihuse. Nibintu byingenzi byingenzi bigaragara mubikorwa bya PCB.
Mu bihe biri imbere, tekinoroji yo gukora micro-umwobo izashingira cyane cyane kumashini ya CNC igezweho yo gucukura hamwe na micro-imitwe myiza. Ibyobo bito byakozwe na tekinoroji ya lazeri biracyari munsi yumwobo muto wakozwe na mashini yo gucukura CNC uhereye kubiciro ndetse nubwiza bwumwobo.
Imashini yo gucukura
Kugeza ubu, tekinoroji ya CNC yo gucukura yateye intambwe nshya niterambere. Kandi yakoze ibisekuru bishya bya mashini yo gucukura CNC irangwa no gucukura utwobo duto.
Imikorere yo gucukura umwobo muto (munsi ya 0,50mm) mumashini icukura micro-umwobo iruta inshuro 1 ugereranije n’imashini zisanzwe za CNC zisanzwe, hamwe no kunanirwa gake, kandi umuvuduko ni 11-15r / min; 0.1-0.2mm ya mwobo irashobora gucukurwa. Ubwiza buhanitse bwo mu rwego rwohejuru buto buto burashobora gucukurwa mukubika amasahani atatu (1.6mm / igice).
Iyo imyitozo ya biti ivunitse, irashobora guhita ihagarara ikanatanga raporo aho ihagaze, igahita isimbuza bito hanyuma ikagenzura diameter (isomero ryibikoresho rishobora kwakira ibice amagana), kandi irashobora guhita igenzura intera ihoraho hamwe nubujyakuzimu bwimbitse bwimyitozo kandi isahani yo gupfuka, kugirango ibyobo bihumye bishobora gucukurwa, Ntabwo bizacukura ameza.
Imbonerahamwe yimashini ya dring ya CNC ikoresha uburyo bwo guhumeka ikirere hamwe nubwoko bwa magnetique, bigenda byihuta, byoroheje kandi neza neza bitarinze kumeza. Imashini zicukura ubu zirazwi cyane, nka Mega 4600 yo muri Prurite mu Butaliyani, Excellon 2000 ikurikirana muri Amerika, hamwe nibicuruzwa bishya nk'Ubusuwisi n'Ubudage.
IndeedHariho ibibazo byinshi bijyanye na laser yo gucukura imashini isanzwe ya CNC yo gucukura na bits yo gucukura imyobo ya micro. Byadindije iterambere rya tekinoroji ya micro-umwobo, bityo isuri ya laser yitabweho, ubushakashatsi no kuyishyira mubikorwa.
Ariko hariho inenge yica, ni ukuvuga, gushiraho imyobo yamahembe, bigenda bikomera uko ubunini bwikibaho bwiyongera. Hamwe nubushyuhe bukabije bwo gukuraho ubushyuhe (cyane cyane imbaho nyinshi), ubuzima no kubungabunga amasoko yumucyo, gusubiramo ukuri kwimyenge yatewe, hamwe nigiciro, kuzamura no gukoresha imyobo mito mubibaho byanditse ni bike.
Nyamara, imyobo ya lazeri iracyakoreshwa muri microplate yoroheje cyane, cyane cyane muri tekinoroji ya MCM-L ihuza cyane (HDI), nka firime ya polyester yometseho umwobo hamwe no gushira ibyuma muri MCMS (Ikoranabuhanga rya Sputtering) ikoreshwa ifatanije nuburebure -ubucucike.
Gukora ibyobo byashyinguwe mubucucike bwinshi buhujwe nimbaho nyinshi zubatswe hamwe nububiko bwimpumyi kandi buhumye nabyo birashobora 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 haracyariho ahantu runaka.
③ yashyinguwe, impumyi, binyuze mu mwobo tekinoloji yashyinguwe, impumyi, ikoresheje uburyo bwo guhuza imiyoboro nayo ni inzira yingenzi yo kongera ubucucike bwumuzingo wacapwe.
Mubisanzwe, imyobo yashyinguwe nimpumyi ni utwobo duto. Usibye kongera umubare winsinga kurubaho, umwobo ushyinguwe nimpumyi ukoresha "hafi" ihuza imiyoboro ihuza ibice, igabanya cyane umubare wu mwobo wakozwe kandi ibyapa byo kwigunga nabyo bizagabanuka cyane, bityo byongere umubare wogukoresha neza no guhuza imiyoboro ihuza imbaho, no kongera ubucucike bwimikoranire.
Kubwibyo, ikibaho cyibice byinshi byahujwe no gushyingurwa, impumyi, no kunyura mu mwobo bifite ubwuzuzanye bwikubye byibuze inshuro 3 kurenza ubw'ibisanzwe bisanzwe byuzuye byuzuye umwobo ku bunini bumwe n'umubare w'ibyiciro. Niba ushyinguwe, impumyi, nubunini bwibibaho byacapishijwe hamwe nu mwobo bizagabanuka cyane cyangwa umubare wibice bizagabanuka cyane.
Kubwibyo, mubucucike bukabije bwubatswe hejuru yububiko bwanditseho, tekinoroji yashyinguwe hamwe nimpumyi zubuhumyi zirakoreshwa cyane, atari mubibaho byanditse hejuru yububiko bwa mudasobwa nini nibikoresho byitumanaho, ariko no mubikorwa bya gisivili ninganda. Yarakoreshejwe kandi mu murima, ndetse no mu mbaho zimwe zoroshye, nka PCMCIA zitandukanye, Smard, amakarita ya IC hamwe n’ibindi bito bitandatu.
Ikibaho cyumuzunguruko cyacapwe hamwe nu mwobo wubatswe hamwe nimpumyi muri rusange byuzuzwa nuburyo bwo gukora "sub-board", bivuze ko bishobora kurangira nyuma yamasahani menshi yo gukanda, gucukura, gusiba umwobo, nibindi, bityo guhagarara neza ni ngombwa cyane.
