Urupapuro rw'umuringa ruzungurutseIfite uruhare runini mu nganda ziteye imbere nka za electronic circuits, bateri nshya z'ingufu, no kurinda ingufu za elegitoroniki. Imikorere yayo n'ubwizerwe bwayo bigenwa n'uburyo ikorwa neza ndetse n'uburyo ihinduka. Iyi nkuru irasuzuma urugendo rwuzuye rwo gukora za rolledurupapuro rw'umuringamu buryo bw'umwuga kandi igasobanura uburyo iha imbaraga inganda zigezweho binyuze mu bisubizo byabugenewe.
I. Uburyo bwo gukora ibintu busanzwe: Kunoza imikorere n'imikorere myiza
1. Gucana Ingot y'umuringa: Aho gutangirira ubuziranenge n'imiterere
Hakoreshejwe umuringa ukozwe mu buryo bwa elegitoroniki (≥99.99%), ibikoresho bishongeshwa mu cyuma gishyushye kandi bigashyirwa mu byuma bifite ubugari bwa mm 100–200. Igipimo cy'ubukonje kigenzurwa cyane kugira ngo habeho uduce duto, dusa kandi hirindwe ko hacikamo uduce mu gihe cyo kuzunguruka nyuma.
2. Gushyuha cyane: Intambwe ya mbere mu kugabanya ububyibuho
Uduce tw'umuringa dushyushye cyane tukazunguruka kugeza kuri 5–10mm kuri 700–900°C hakoreshejwe icyuma gisya gishobora gusubira inyuma. Gusiga amavuta bigabanya kwangirika kw'udupira kandi bikagabanya stress z'imbere mu gucukura, bigashyiraho urufatiro rwo kuzunguruka neza.
3. Gusukura no gukoresha neza ubuso
Uruvange rwa aside nitrike-sulfuriki (10–15% by'ibipimo) rukoreshwa mu gukuraho ogisijeni. Uburyo bwo gutunganya amashanyarazi bugabanya ubukana bw'ubuso (Ra) kugeza munsi ya 0.2μm, bigatuma umusaruro uba mwiza mu gukomeza kuzunguruka.
4. Kuzunguruka neza: Kugera ku buziranenge bwo ku rwego rwa mikoroni
Uburyo bwinshi bwo gukonjesha bugabanya umuringa kugeza kuri mm 0.1–0.2. Hamwe n'inganda zikora ubukana bwinshi n'ubunini bwa laser (± 2μm), ihindagurika ry'ubunini riguma muri 1%. Imbaraga zo gukonjesha n'ubukana bigenzurwa neza kugira ngo hirindwe ko impande zicika.
5. Gutembera kuri foil: Gukora ubuso buto cyane
Uruganda rukora foil ruteye imbere rukoresha uburyo bwo guhindura icyuho gito n'amavuta kugira ngo rugere ku bugari bwa 9–90μm. Irangi ry'ubuso rirenze ISO 1302 grade 12, rikwiriye gukoreshwa mu ruhu rwa 5G rukoresha uruhu rwinshi.
6. Gukuraho amavuta: Intambwe ya nyuma yo gusukura ubuso
Gusukura hakoreshejwe ikoranabuhanga rigezweho hamwe no gukuraho amavuta ya alkaline (pH 11–13) bikuraho amavuta asigaye yo gukurura. Ibisigazwa bya karuboni bigenzurwa munsi ya 5mg/m², bigatanga urufatiro rwiza rwo gutunganya ubuso.
7. Gukata no gupakira: Ubuhanga mu nganda hamwe n'ubwiza bw'ubwiza
Ibikoresho bitwikiriwe na diyama bifite ubugari bwa ± 0.1mm. Ibicuruzwa bishyirwa mu cyuma gikingira ogisijeni kandi bikabikwa ahantu hagenzurwa n'ikirere (25±2°C, ≤70% RH) kugira ngo bikomeze koherezwa.
II. Gutunganya Ibikoresho Bijyanye n'Ikoranabuhanga: Kongera Imikorere Yihariye mu Nganda
1. Annealing: Guhindura Imiterere ya Mechanical
Umutima woroshye (O):Ishyizwe ku bushyuhe bwa 400–600°C munsi y’ikirere cya H₂/N₂ mu gihe cy’amasaha 2–4. Ingufu zo gukurura zigabanuka zikagera kuri 200–250MPa kandi uburebure bukazamuka bukagera kuri 25–40%, bikaba ari byiza cyane mu kuzunguruka kw’urukiramende.
Uburakari bukomeye (H):Igumana imbaraga zikomejwe n'akazi (400–500MPa), ikanatuma ibice bya IC bigumana ubusugire.
2. Ubuvuzi bw'ubuso: Kuvugurura imikorere
Gukangura:Guca ibintu mu buryo bw'imiti birema udusimba twa 1–2μm, byongera uburyo resin ifatana na 1.5N/mm cyangwa irenga—bikemura ibibazo byo gutandukanya imiterere y'urumuri mu mbaho za 5G.
Igipfunyika cya nikeli/agasanduku:Irangi rya 0.1–0.3μm ritanga ubudahangarwa bwa 10× corruption, rikwiriye kuri bateri za EV.
Igipfukisho gishyuha cyane:Ingufu za Zn nano-coating zigumana ubushyuhe burambye kuri dogere selisiyusi 300, zigafasha insinga z'indege zikenewe.
III. Guha imbaraga inganda z'ingenzi binyuze mu guhanga udushya mu mikorere
Ikoranabuhanga:Igitambaro cya 9μm gifatanye n'icyuma gishyushya gifasha ubugari bw'umurongo wa HDI munsi ya 12μm, gitanga ingufu zo gukora terefone zigendanwa.
Bateri za EV:Agapapuro k'umukara gafite uburebure bwa ≥20% gashobora gukomera mu gutwi inshuro zirenga 3000, bigatuma bateri ikomeza gukora neza.
Uburinzi bwa EMI:Urupapuro rwa nikeli rufite uburinzi bwa 120dB kuri 10GHz, rukaba rwiza cyane ku bikorwa remezo by’ikigo cy’amakuru.
IV. CIVEN METAL: Gushyiraho Ibipimo ngenderwaho mu Gutunganya Udupapuro tw'Umuringa
Nk'umuyobozi muriagapapuro k'umuringa kazinzeinganda,ICYUMA CYA CIVENyashyizeho uburyo bworoshye bwo gukora buvanga inzira zisanzwe n'uburyo bwo guhindura ibintu mu buryo busanzwe:
Amaduka yo gusukura cyane hamwe n'uburyo bwo kugenzura MES bifasha ±2μm ubugari n'ubugari ≤1I.
Amatanura yo gukurura ashobora gushyirwa mu buryo bwa porogaramu atwara ibintu 20 byihariye icyarimwe.
"Isomero ryo gutunganya ubuso" ryihariye rigizwe n'ubwoko 12 bwo gukaraba hamwe n'uburyo 8 bwo gushushanya hakoreshejwe amashanyarazi, hamwe n'amasaha 72 yo gusubiza.
Kunoza imikorere no gushakisha ibicuruzwa byinshi bigabanya ibiciro bya foil byihariye ho 15–20% ugereranije n'impuzandengo ku isoko.
Kuva ku biti binini bya milimetero kugeza ku biti bito cyane, gukora ibiti by'umuringa bizungurutse ni imbyino y'ubumenyi bw'ibikoresho n'ubuhanga mu by'ubuhanga. Uko impinduka za 5G n'ingufu zigenda zitera imbere, ni amasosiyete ahuza ubuziranenge busanzwe n'uburyo bwo guhindura ibintu mu buryo bwimbitse gusa ashobora gukomeza gutera imbere.ICYUMA CYA CIVENari guteza imbere iyi mpinduka, afasha Ubushinwaurupapuro rw'umuringainganda zizamuka mu ruhererekane rw'agaciro ku isi.
