Ni gute PCB Ikoresha Ikoranabuhanga Mpuzamahanga? "Ikarita y'imitsi" Ihishe mu bikoresho by'ikoranabuhanga
Iyo ukoresheje kode ya QR kugira ngo umenye uburyo bwo kwishyura hakoreshejwe telefoni zigendanwa, iyo sisitemu yo kuyobora imodoka igena inzira nyayo, cyangwa iyo ibimenyetso bya satelite binyura mu isanzure kugira ngo bigere ku Isi, "agatsiko k'ikoranabuhanga" katagaragara kaba karimo gukora cyane - ikibaho cyacapwe (PCB). Iki kibaho gisa n'aho gisanzwe gikora nk'aho ikarita y'imitsi by'ikoranabuhanga, bivanga ibice bibarirwa muri za miriyari mu buryo bw'ubwenge. Kuva ku magare ahuriweho n'abanyamagare kugeza ku marobo yo gushakisha mu nyanja, kuva ku byuma bipima neza kugeza ku bigo by'itumanaho binyura ku mugabane, hejuru 90% by'ibikoresho by'ikoranabuhanga ku isi twishingikirize ku nkunga yayo. Uyu munsi, reka twirebere mu isi y'iyi "circuit board" kugira ngo turebe uburyo ikoresha ibikoresho n'ubukorikori kugira ngo ibe ibuye ry'ifatizo ryihishe ry'ikoranabuhanga rigezweho.
I. Ubumaji bwo Guhindura Imiterere: Kuva ku "Ibikoresho by'Ikoranabuhanga" kugeza ku "Ababyinnyi Bazingira"
1. Labyrinths zifite amashami
·Intangiriro zoroshye: PCB y'ibanze ifite urwego rubiri ikora nk'"inoti ya digital Post-it", iyobora imiyoboro ku mpande zombi. Uzayisanga muri calculators na remotes.
·Ibihangano by'ubukorikori bigoye: PCB zo mu rwego rwo hejuru zirata Inzego 68— "croissant ya digitale" ifite ubuziranenge. Utu duce (imbaraga, ikimenyetso, ubutaka) dukwira mu bunini bwa milimetero imwe gusa, nk'aho dushyira impapuro 68 z'impapuro nto cyane mu gishushanyo cya A4.
2. Ikomeye cyangwa Ihindagurika
·Imbaho zikomeye: Substrates za FR-4, "beto y'ikoranabuhanga," zigize urufatiro rw'amabati y'ababyeyi ya mudasobwa na televiziyo.
·Ibitangaza bihindagurika: PCB zihindagurika zishingiye kuri Polyimide (PI) zigonga Inshuro 30.000 idacika, ituma ecran za telefoni zigendanwa zishobora gupfunyika hamwe n'ibikoresho bifasha umutima gutera umutima mu mugongo bireba umubiri w'umuntu.
·Abapfumu b'ibihuzwa: Imiterere ihamye ihuza imbaraga n'ubushobozi bworoshye. Urugero, ibikoresho byo mu matwi bikoresha ibice bikomeye ku byuma bito n'ibice byoroshye ku nsinga, imikorere yo kuringaniza n'imiterere.
II. Ubuhanga mu by'Ibintu: Kuva ku "Intwaro zishyuha" kugeza ku "Imihanda minini"
1. Abarinda ibanze
Ubwiganze bwa FR-4: Kubara amafaranga kuri 70% Mu bikoresho bya PCB ku isi, FR-4 (epoxy igabanya umuriro) irahendutse, ikoreshwa mu buryo butandukanye, kandi iboneka muri byose kuva ku bikinisho kugeza ku bikoresho.
Abakinnyi bakomeye mu gushushanya ibyuma:
- Al₂O₃ substrates: "Inkingi irinda ubushyuhe" ku bikoresho bya moteri z'imodoka.
- Ibyuma bya AlN: Hamwe na Ubushobozi bwo gutwara ubushyuhe bwiyongera inshuro 200 kurusha FR-4, birinda uduce twa 5G base station kudashyuha cyane.
2. Abahanga mu gukwirakwiza amakuru menshi
PTFE na Rogers: Ibi bikoresho byitwa "imihanda minini y'amasimbuka," bikoresha amashanyarazi make kandi bidakoresha amashanyarazi menshi (hasi kugeza kuri 2.1) bifasha kohereza neza ubutumwa bwa 5G—ni ngombwa kuri routers na antene za satelite.
3. Udushya mu byuma by'ingenzi
- Ibintu bya aluminiyumu: "Ibikoresho bikonjesha by'ikoranabuhanga" bikoreshwa mu gukwirakwiza ubushyuhe bwa LED.
- PCB z'umuringa mwinshi: "Imitsi y'amashanyarazi" ifite 100A+, ni ingenzi cyane kuri sisitemu za bateri za EV.
III. Ubukorikori bwa Nanoscale: Imiyoboro ya Micron-Level
1. Ihuriro ry'Ubucucike Bukomeye (HDI)
Tekereza kubaka umujyi ku cyuma gisa n'inzara. Microvias () n'inzira zihishe/zishyinguwe zihindura inzira zigororotse zihinduka Imiyoboro ya 3D. Imiterere ya motherboard ya iPhone Ibice birenga 100,000 muri 50cm²—bingana no gupakira abantu 200.000 ku rupapuro rwa A4!
2. Irangi ry'ubuso: "Ingando ya Zahabu"
- NDEMERA: Agace gato ka zahabu gafite nanometero gakingira ibimenyetso byangiritse—ni byiza cyane gukoreshwa muri 5G no mu buvuzi.
- HASL: Igipfunyika cya tin-lead gipima ikiguzi n'imikorere y'ibikoresho by'ikoranabuhanga bisanzwe.
- Ishami rishinzwe kuzimya umuriro ry’abakorerabushake: A Filimi y'umwimerere ifite ubugari bwa 0.2μm byoroshya gushongesha ariko bisaba kugenzura ubushuhe.
3. Ubuhanga bwihariye
- Gucukura mu buryo bugenzurwa: "Acupuncture y'ikoranabuhanga" yirinda kwangiza ibice by'imbere mu buryo bw'ingenzi.
- PCB zifite umwobo umwe: Emera ko habaho guhuza impande zidafite imigozi n'udusanduku tw'ibyuma mu bikoresho by'inganda.
IV. Ahazaza Haragaragara: PCB mu gihe cy'ubwenge
1. Amasano ari hejuru
Kuri 6G (100+ GHz), substrates zifite dielectric constants igihombo cy'ikimenyetso cya kabiri.
2. Impinduramatwara mu guhuza
Ibice byashyizwemo: Utwuma duto (chips) na capacitors (capacitors) biri mu gice cya PCB ubwacyo—bigabanya ingano y'ibikoresho byambarwa na 30%.
3. Guhanga udushya mu bidukikije
Ibikoresho bitagira icyuma gikoreshwa mu gusya kandi bishobora kongera gukoreshwa (urugero, epoxy ishingiye ku binyabuzima) ijyanye n'amabwiriza ya RoHS, binazana urukurikirane rushya rw'inshingano zo kubungabunga ibidukikije mu by'ikoranabuhanga.
Umusozo: Gukora ku "mpera z'imitsi" z'ikoranabuhanga
Ubutaha ugiye gusenya telefoni ishaje, reba PCB yayo yangiritse. Buri gice cy'inyuma ni icya injeniyeri umukono, buri buye rito rihuza igihamya cy'ubuhanga mu bikoresho. Kuva ryavumburwa muri 1936, PCB yavuye ku "gikoresho gitwara ibintu" gusa ijya ku metronome y'iterambere ry'ikoranabuhanga: amabati yoroshye yafashije gutwara ibintu, amabati yo mu bwoko bwa "high-frequency" yubatse ibiraro by'itumanaho, kandi HDI yafunguye ingufu zitagira imipaka za chip.
Mu gihe turota ibintu bidasanzwe, ibinyabiziga byigenga, n'ubushakashatsi bw'ikirere, ibuka—icyerekezo cyose gitangirana n'iri jambo rituje igikanka cy'ikoranabuhanga, itwara ibimenyetso bya za tiriyari hirya no hino ku isi.
Itsinda ubushyuhe bw'ikoranabuhanga iherereye muri buri murongo usobanutse neza. Ahazaza h'ikiremwamuntu, byemewe bucece n'aya "makarita y'imitsi" atagaragara.
