Ibhodi lesifunda eliphakeme eliphakeme lisho ukusetshenziswa komugqa omuhle ububanzi / izikhala, izimbobo ezincane, ububanzi bendandatho emincane (noma ububanzi bendandatho (noma i-ring izimbobo zokuthola ukufezekisa ubukhulu.
Ukucaciswa okuphezulu kusho ukuthi umphumela 'wenhlawulo, omncane, omncane, futhi omncane "uzokuholela ezifuyweni eziphezulu zokunemba. Thatha umugqa ububanzi njengesibonelo:
I-0.20mm Line Ububanzi, 0.16 ~ 0.24mm akhiqizwa ngokuya ngemithetho efanelekile, futhi iphutha (0.20 ± 0.04) MM; Ngenkathi umugqa ububanzi obungu-0.10mm, iphutha ngu (0.1 Kepha kuyinkinga evelele kubuchwepheshe bokukhiqiza.
Ubuchwepheshe obuncane nobuminyene
Esikhathini esizayo, ububanzi obukhulu obunobukhulu obuphakeme buzosuka ku-0.20mm-0.13mm-0.08mm-0.005mm ukufeza izidingo ze-SMT ne-Multi-Chip Packal (Mulitichip Package, MCP). Ngakho-ke, ubuchwepheshe obulandelayo buyadingeka.
①ubstrate
Kusetshenziswa i-foil ye-foil ye-foil emincane noma ye-ultra-mncane (<18um) substrate nobuchwepheshe bokwelashwa okuhle.
②process
Usebenzisa i-Thinner Dryner Film nenqubo yokunamathisela emanzi, ifilimu elincanyana elisha futhi elihle linganciphisa ukuhlanekezela komugqa kanye nezinkinga. Ifilimu elimanzi lingagcwalisa izikhala ezincanyana zomoya, khulisa ukunamathela kwesikhombimsebenzisi, futhi uthuthukise ubuqotho kanye nokunemba.
Ifilimu ye-Photoresist ye-Photoresist
I-Photoresist ebekelwe i-Electro-ebekiwe (ed). Ubukhulu bawo bungalawulwa ku-5-30 / Um, futhi kungakhiqiza izintambo ezinhle kakhulu. Ilungele ikakhulukazi ububanzi bendandatho emincane, akukho bubanzi bendandatho kanye ne-electrote egcwele yeplate. Njengamanje, kunemigqa engaphezu kweshumi yokukhiqiza e-Ed emhlabeni.
④ Ubuchwepheshe bokuchayeka kokukhanya okufanayo
Kusetshenziswa ubuchwepheshe bokuvezwa kokukhanya okufana. Njengoba ukuvezwa kokukhanya okufanayo kunganqoba ithonya lokuguquguquka kobubanzi obubangelwa imisebe ekhanyayo "iphuzu" elikhanyayo, ucingo oluhle olunosayizi onobubanzi obuhle nemiphetho ebushelelezi engatholakala. Kodwa-ke, imishini yokuvezwa okufanayo iyabiza, ukutshalwa kwezimali kuphezulu, futhi kuyadingeka ukuthi usebenze endaweni ehlanzekile kakhulu.
⑤automatic optical wokuhlola ubuchwepheshe
Usebenzisa ubuchwepheshe bokuhlola okuzenzakalelayo. Lobu buchwepheshe sebuphenduke izindlela ezisemqoka zokutholwa ekwenziweni kwezintambo ezinhle, futhi kuyakhuthazwa ngokushesha, kufakwa futhi kuthuthukiswe.

Ubuchwepheshe obunobuchwepheshe be-micropororous
Izimbobo ezisebenzayo zamabhodi aphrintiwe asetshenziselwa ukufakwa ebukhoneni ubuchwepheshe be-microplorous asetshenziselwa ukuxhumeka ngogesi, okwenza ukusetshenziswa kobuchwepheshe be-microporous kubaluleke kakhulu. Kusetshenziswa izinto ezijwayelekile zokumba kanye nemishini yokumba e-CNC ukukhiqiza izimbobo ezincane kunehluleka okuningi nezindleko eziphakeme.
Ngakho-ke, ubukhulu bamabhodi aphezulu bagxile kakhulu ekuconyweni kwezintambo namaphara. Yize imiphumela emihle itholwe, kungenzeka ukuthi kulinganiselwe. Ukuqhubeka nokwenza ngcono ubuningi (njengezintambo ezingaphansi kuka-0.08mm), izindleko ziyakhuphuka. , Ngakho-ke, phenduka ukuze usebenzise ama-micropores ukuze uthuthukise ukuhlanganiswa.
Eminyakeni yamuva nje, imishini yokumba izinombolo yokulawula kanye nobuchwepheshe be-micro-drill yenze ama-breakthroughs, futhi ngaleyo ndlela ubuchwepheshe be-micro-hole buye bakhula ngokushesha okukhulu. Lesi yisici esiyinhloko esivelele ekukhiqizweni kwe-PCB yamanje.
Esikhathini esizayo, ubuchwepheshe bokwakha umgodi bamba ama-Micro-hole buzothembela kakhulu emishini yokushayela ethuthukile ye-CNC kanye namakhanda amancane amancane, futhi izimbobo ezincane ezakhiwe yi-laser technology zisaphansi kwalezo ezakhelwe imishini yokushayela ye-CNC kusuka ngombono wezindleko kanye nekhwalithi yomgodi.
Umshini wokumba we-①cnc
Njengamanje, ubuchwepheshe beCNC Drilling Machine wenze ama-Breakthrough amasha nenqubekela phambili. Futhi kwakha isizukulwane esisha somshini wokumba kwe-CNC obonakala ngokumba izimbobo ezincane.
Ukusebenza kahle kokumba izimbobo ezincane (ngaphansi kuka-0.50mm) womshini wokushayela umgodi we-micro-hole kuphakeme kakhulu kunalokho komshini wokushayela i-CNC, ngokuhluleka okumbalwa, nejubane lokujikeleza kungu-11-15r / min; Ingashayela i-0.1-0.2mm micro-holes, isebenzisa okuqukethwe okuphezulu kwe-cobalt. I-drill encane esezingeni eliphakeme ingadonsa amapuleti amathathu (1.6mm / block) ifakwe phezulu komunye nomunye. Lapho i-drill bit yephuliwe, ingamisa ngokuzenzakalelayo futhi ibike isikhundla, ibheke ngokuzenzakalelayo i-drill bit bese ibheka ububanzi phakathi kwethiphu yokudonsa), futhi ingalawula ngokuzenzakalela ibanga eliphakathi kwethiphu yokumba), futhi kungahle kulawule i-countertop. Ithebula eliphakeme lomshini wokumba kwe-CNC lamukela i-air cushion kanye nohlobo lwe-magnetic magritation, olungashukumisela ngokushesha, okulula futhi okunembile ngaphandle kokushaya itafula.
Imishini enjalo yokumba njengamanje iyafunwa, njenge-mega 4600 kusuka ePrarite e-Italy, e-Excelson 2000 Series e-United States, nemikhiqizo yesizukulwane esisha evela eSwitzerland naseJalimane.
②Laser yokumba
Kunezinkinga eziningi kakhulu ngemishini yokumba evamile ye-CNC kanye nama-bits drill ukumba izimbobo ezincane. Iye yathi inqubekela phambili yobuchwepheshe obuncanyana umgodi, ngakho-ke i-laser ablation idonsele ukunakwa, ukucwaninga kanye nesicelo.
Kepha kunokushiyeka okubulalayo, okungukuthi, ukwakheka komgodi wephondo, okuba kubi kakhulu njengoba ubukhulu bepuleti bukhuphuka. Kuhlanganiswe nokungcoliswa kokushisa okushisa okuphezulu (ikakhulukazi amabhodi we-multilayer), impilo kanye nokugcinwa komthombo wokukhanya, ukuphindaphinda kwezimbobo zokugqwala, kanye nezindleko, ukukhushulwa kanye nokusetshenziswa kwezimbobo ezincane ekukhiqizweni kwamabhodi aphrintiwe kuvinjelwe. Kodwa-ke, ukucwaswa kwe-laser kusasetshenziswa kumapuleti amancanyana futhi aphezulu ama-micpororous, ikakhulukazi kubuchwepheshe be-MCM-LOPH-DENSHENTITY InterConnect (HDI), njenge-polyester ifilimu etching kanye nokubekwa kwensimbi kuma-MCM. (Ubuchwepheshe obukhohlisayo) busetshenziswa ekuxhumekeni okuhlangene okuphezulu.
Ukwakheka kwama-viais angcwatshwe ku-High-density uxhumano amabhodi we-multilayer ama-milconner angcwatshwe futhi angaboni ngezakhiwo ezimpumputhe nazo zingafakwa. Kodwa-ke, ngenxa yentuthuko yezobuchwepheshe yemishini yokumba e-CNC kanye nokushayela ama-micro-micro-a, bathuthukiswa ngokushesha futhi basebenza. Ngakho-ke, ukusetshenziswa kwe-laser dripling emabhodini we-surface Mount Ball awakwazi ukwakha isikhundla esivelele. Kepha kusenayo indawo ensimini ethile.
I-③bukela, eyimpumputhe, nobuchwepheshe be-pay hole
Ubuchwepheshe obuyimpumputhe, obumpumputhe, nobuchwepheshe bezinhlanganiso ze-Bhole buyindlela ebalulekile yokwandisa ubungako bemibuthano ephrintiwe. Ngokuvamile, izimbobo ezibunjiwe nezimpumputhe ziyizimbobo ezincane. Ngaphezu kokukhulisa inani le-wiring ebhodini, izimbobo ezingcwatshwe futhi ezingaboni zixhumeke kakhulu yileva yangaphakathi, futhi ukulungiswa kwe-isolate disk kuzonciphisa kakhulu, kanye nokwenza isibalo sokuxhumeka okusebenzayo kanye nokuxhumana kwe-interconnection.
Ngakho-ke, ibhodi elinemibuthane elinenhlanganisela yokungcwatshwa, okuyimpumputhe, kanye nezimbobo eziphakeme okungenani zinezikhathi ezi-3 eziphakeme zokuxhumeka kwe-interconnection kunesakhiwo esijwayelekile sebhodi eligcwele ngaphansi kwesilinganiso esilinganayo nenombolo yezendlalelo. Uma kungcwatshwe, izimpumputhe, usayizi wamabhodi aphrintiwe ahlanganiswe nezimbobo kuzoncishiswa kakhulu noma inani lezendlalelo lizoncishiswa kakhulu.
Ngakho-ke, emabhodini aqongelwe kakhulu afakwe endaweni ebekwe phezulu, angcwatshwe kanye nobuchwepheshe obuyimpumputhe abasekusetshenzisiwe, hhayi emabhodini aphrintiwe angaphezulu kwamakhompyutha amakhulu, imishini yokuxhumana, njll., Kepha nezicelo zomphakathi. Kusetshenziswe futhi kabanzi ensimini, ngisho nakwamanye amabhodi amancane, njenge-PCMcia, ama-smard, amakhadi e-IC namanye amabhodi amancane aphansi.
Amabhodi wesifunda aphrintiwe anezinhlaka ezingcwatshwe futhi ezimpumputhe zivame ukuqedwa yizindlela zokukhiqiza "ezingezansi", okusho ukuthi kumele ziphothulwe ngokucindezela okuningi, ukumba, kanye nokufakwa okunembile kubaluleke kakhulu.
