High precision circuit board zvinoreva kushandiswa kwehupamhi hwemutsara wemutsara, tumaburi tudiki, hupamhi hwemhete (kana kusava nehupamhi hwemhete), nemakomba akavigwa nemapofu kuti awane hupamhi hwepamusoro.Uye kunyatsojeka kunoreva kuti mhedzisiro ye "yakaonda, diki, nhete, yakatetepa" ichaunza zvisingadzivisiki zvinodikanwa zvakanyanya, tora upamhi hwemutsara semuenzaniso: O. 20mm mutsara wakafara, maererano nemirairo yekugadzira O. 16 ~ 0.24mm inokodzera, kukanganisa ndiko (O.20 ± 0.04) mm;uye O. Pamutsara wehupamhi hwe10mm, kukanganisa ndiko (0.10±0.02) mm.Sezviri pachena, kururamisa kwekupedzisira kwakapetwa kaviri, uye zvakadaro hazvisi zvakaoma kunzwisisa, saka izvo zvinodiwa zvepamusoro-soro hazvizokurukurwa zvakasiyana.Asi idambudziko rakakurumbira mukugadzira tekinoroji. 
(1) Fine waya tekinoroji
Iyo remangwana yakakwirira yakanaka waya hupamhi / nzvimbo ichashandurwa kubva pa0.20mm-O.13mm-0.08mm-0.005mm inogona kusangana nezvinodiwa zveSMT uye akawanda-chip package (Multichip Package, MCP).Nokudaro, nzira dzinotevera dzinodiwa.
①Kushandisa yakaonda kana yakanyanyisa-yakatetepa yemhangura foil (<18um) substrate uye yakanaka yepamusoro yekurapa tekinoroji. ②Kushandiswa kwefirimu yakaoma yakaoma uye yakanyorova firimu, yakaonda uye yakanaka mhando yakaoma firimu inogona kuderedza mutsara wakafara kukanganisa uye kukanganisa.Wet lamination inogona kuzadza madiki madiki emhepo, kuwedzera kunamatira kwemukati, uye kunatsiridza waya kutendeseka uye iko kurongeka. ③ Kushandisa electrodeposited photoresist firimu (Electro-deposited Photoresist, ED).Ukobvu hwayo hunogona kudzorwa muhupamhi hwe5-30/um, iyo inogona kuburitsa yakanyanya kukwana waya yakanaka, kunyanya yakakodzera kune yakamanikana mhete yakafara, isina mhete upamhi uye yakazara-bhodhi electroplating.Parizvino, kune anopfuura gumi mitsara yekugadzira ED munyika. ④Kushandisa parallel light exposure tekinoroji.Sezvo kuratidzwa kwechiedza chakafanana kuchikwanisa kukurira pesvedzero yekusiyana kwehupamhi hwemutsara inokonzerwa nechiedza che oblique che "point" mwenje sosi, waya dzakanaka dzine mitsara yehupamhi hwehupamhi uye mipendero yakachena inogona kuwanikwa.Zvisinei, parallel exposure equipment inodhura, inoda mari yakawanda, uye inoda kushanda munzvimbo ine hutsanana hwepamusoro. ⑤ Adopt otomatiki optical inspection tekinoroji (Automatic Optical Inspection, AOI).Iyi tekinoroji yave nzira yakakosha yekuona mukugadzirwa kwewaya dzakanaka, uye iri kukurumidza kusimudzirwa, kushandiswa nekuvandudzwa.Semuyenzaniso, AT&T Kambani ine gumi nerimwe AoIs, uye}tadco Kambani ine makumi maviri nerimwe AoIs anonyanya kushandiswa kuona magirafu emukati. (2) Microvia tekinoroji
Iwo maburi anoshanda emapuranga akadhindwa anoshandiswa pakukwirisa pamusoro anonyanya kuita basa rekubatanidza magetsi, izvo zvinoita kuti kushandiswa kweiyo microvia tekinoroji kuve yakakosha.Kushandisa zvakajairwa kudhirowa zvimedu uye CNC yekuchera michina kugadzira maburi madiki kune kutadza kwakawanda uye kudhura kwakanyanya.Naizvozvo, kuwanda kwemabhodhi akadhindwa kunonyanya kukonzerwa nekuwanda kwewaya nemapadhi.Kunyange zvazvo budiriro huru dzakaitwa, kugona kwayo kune painogumira.Kuti uwedzere kuvandudza densification (senge waya isingasviki 0.08mm), mutengo wacho ndewekukurumidza.litres, nokudaro kutendeukira kukushandiswa kwema micropores kuvandudza densification.
Mumakore achangopfuura, kubudirira kwakaitwa muCNC yekuchera muchina uye micro-drill tekinoroji, saka tekinoroji yegomba yakagadzira nekukurumidza.Ichi ndicho chinhu chikuru chakakurumbira mukugadzirwa kwePCB ikozvino.Mune ramangwana, tekinoroji yekugadzira maburi madiki ichanyanya kuvimba nemichina yekuchera CNC uye misoro midiki yakanaka, nepo maburi akaumbwa nelaser tekinoroji achiri akaderera kune ayo akaumbwa neCNC yekuchera michina kubva pakuona mutengo uye gomba mhando. . ①CNC yekuchera muchina Parizvino, tekinoroji yemuchina wekuchera CNC waita mabudiro matsva nekufambira mberi.Uye yakagadzira chizvarwa chitsva cheCNC yekuchera muchina unozivikanwa nekuchera maburi madiki.Kubudirira kwekuchera makomba maduku (pasi pe 0.50mm) nemuchina wekuchera micro-hole yakakwira 1 nguva kupfuura yeCNC yekuchera muchina, ine kukundikana kushoma, uye kumhanya kwekutenderera i11-15r / min;inogona kuboora O. 1 ~ 0.2mm maburi madiki, madiki emhando yepamusoro ane cobalt yakakwira anoshandiswa, uye ma plates matatu (1.6mm/block) anogona kurongedzerwa pakuboora.Kana chibooreso chikatyoka, chinogona kumira otomatiki uye kushuma chinzvimbo, otomatiki kutsiva chibooreso uye tarisa dhayamita (iyo magazini yekushandisa inogona kugarisa mazana ezvimedu), uye inogona kudzora otomatiki chinhambwe chinogara chiri pakati pechibooreso uye kavha. ndiro uye kudzika kwekuchera, saka maburi mapofu anogona kucherwa., uye haizokuvadza countertop.Iyo CNC yekuchera muchina tafura inotora mhepo cushion uye magineti inoyangarara mhando, inofamba nekukurumidza, yakareruka uye yakanyatsojeka, uye isingakwenye tafura.Michina yekudhirowa yakadaro parizvino iri kushomeka, seMega 4600 kubva kuPrute kuItaly, iyo ExcelIon 2000 yakatevedzana muUnited States, uye zvigadzirwa zvechizvarwa chitsva kubva kuSwitzerland neGermany. ② Chokwadi kune matambudziko mazhinji nelaser drilling yakajairwa CNC yekuchera michina uye madhiri ekuboora makomba madiki.Izvo zvakatadzisa kufambira mberi kweiyo micro hole tekinoroji, saka laser gomba etching yakabhadharwa, kutsvagisa uye kushandisa.Asi pane kukanganisa kunouraya, ndiko kuti, kuumbwa kwemakomba enyanga, iyo inowedzera nekuwedzera kweplate thick.Pamusoro pekusvibiswa kwekupisa kwekushisa kwepamusoro (kunyanya mabhodhi e-multi-layer), hupenyu nekuchengetedza kwechiedza, kudzokororwa kwegomba rekucheka uye mutengo, kusimudzirwa uye kushandiswa kwema microholes mukugadzirwa kwemabhodhi akadhindwa ane. anga akaganhurirwa.Nekudaro, laser ablation ichiri kushandiswa mutete uye akakwira-density microplates, kunyanya muiyo yepamusoro-density interconnect (HDI) tekinoroji yeMCM-L, senge M.Yakashandiswa mukubatanidzwa kwepamusoro-density kusanganisa polyester firimu etching muMs uye simbi deposition (sputtering technique).Kuvigwa kuburikidza nekuumbwa mune yakakwirira-density interconnect multilayer mabhodhi akavigwa uye mapofu kuburikidza nezvimiro anogona zvakare kuiswa.Nekudaro, nekuda kwebudiriro uye tekinoroji yeCNC yekuchera michina uye madiki madiki ekudhira, ivo vakakurumidza kusimudzirwa uye kushandiswa.Saka laser yakaboora maburi pamusoro Zvikumbiro mumabhodhi edunhu akaiswa hazvigone kuumba hutongi.Asi ichine nzvimbo mune imwe ndima. ③Tekinoroji yakavigwa, mapofu uye kuburikidza negomba Iko kusanganiswa kwekuvigwa, bofu uye kuburikidza negomba tekinoroji zvakare inzira yakakosha yekuvandudza dhizaini yakakwira yemaseketi akadhindwa.Kazhinji, akavigwa uye mapofu vias maburi madiki.Kuwedzera kuwedzera nhamba wirings pabhodhi, akavigwa uye mapofu vias vari interconnected pakati "pedyo" yemukati akaturikidzana, izvo zvikuru kunoderedza nhamba kuburikidza nemakomba akaumbwa, uye kugadzika ari oga disc kuchaderedza zvikuru nhamba vias.Yakaderedzwa, nekudaro ichiwedzera huwandu hweanoshanda wiring uye interlayer interlayer interconnection mubhodhi, uye nekuvandudza yakakwira density yekubatana.Naizvozvo, iyo yakawanda-layer board ine musanganiswa wekuvigwa, bofu uye kuburikidza-gomba inokwira kanenge katatu kupfuura yakajairwa yose-kuburikidza-gomba bhodhi chimiro pasi pehukuru hwakafanana uye nhamba yezvikamu.Saizi yebhodhi yakadhindwa yakasanganiswa nemaburi ichaderedzwa zvakanyanya kana huwandu hwematanho huchadzikiswa zvakanyanya.Naizvozvo, mune yakakwirira-density pamusoro pepamusoro pegomo akadhindwa mabhodhi, akavigwa uye mapofu kuburikidza nehunyanzvi ari kuwedzera kushandiswa, kwete chete pamusoro pepamusoro akadhindwa mabhodhi mumakomputa mahombe, michina yekukurukurirana, nezvimwewo, asiwo mumashandisirwo ehurumende nemaindasitiri.Yakave ichishandiswa zvakanyanya mumunda we, uye kunyangwe mune mamwe mabhodhi matete, senge matete mabhodhi ane anopfuura matanhatu akaturikidzana akasiyana PCMCIA, Smart, IC makadhi, nezvimwe. The akadhindwa redunhu mapuranga ane akavigwa uye bofu gomba zvivakwa zvinowanzopedzwa ne "split board" nzira yekugadzira, zvinoreva kuti inogona chete kupedzwa mushure menguva zhinji dzekutsikirira, kudhirowa, gomba plating, nezvimwe, saka kunyatsomira kwakakosha..
