[Inner Circuit] iyo yemhangura foil substrate inotanga kuchekwa kuita saizi yakakodzera kugadzirisa nekugadzira.Pamberi pe substrate firimu kudzvanya, zvinowanzo fanira kuomesera foil yemhangura paplate pamusoro nekukuya bhurashi uye micro etching, wobva wabatanidza iyo yakaoma firimu photoresist pairi tembiricha yakakodzera uye kumanikidza.Iyo substrate yakanamirwa neyakaoma firimu photoresist inotumirwa kune ultraviolet exposure muchina wekuratidzwa.Iyo photoresist ichaburitsa polymerization reaction mushure mekuvhenekerwa ne ultraviolet munzvimbo yakajeka yeasina kunaka, uye mutsara mufananidzo uri pane negative uchaendeswa kune yakaoma firimu photoresist pabhodhi pamusoro.Mushure mekubvarura firimu rinodzivirira riri pamusoro pefirimu, gadzira uye bvisa nzvimbo isina kuvhenekerwa pamusoro pefirimu nesodium carbonate aqueous solution, uye wobva waita ngura uye wobvisa iyo yakafumurwa foil yemhangura nehydrogen peroxide yakasanganiswa mhinduro kuti iite dunhu.Pakupedzisira, photoresist yefirimu yakaoma yakabviswa nechiedza che sodium oxide aqueous solution.
[Kudzvanya] bhodhi remukati redunhu mushure mekupedzwa richabatanidzwa nekunze redunhu copper foil negirazi fiber resin firimu.Usati wadzvanya, ndiro yemukati ichave yakasvibiswa (oxygenated) kuti ipfuure mhangura pamusoro uye kuwedzera kuvhara;Nzvimbo yemhangura yedunhu remukati yakakoshwa kuti ibudise kunamatira kwakanaka nefirimu.Kana ichipindirana, mapuranga emukati ematunhu ane mitsara inodarika matanhatu (kusanganisira) anofanira kukwizwa ari maviri maviri nemuchina weriveting.Wobva waiisa zvakatsvinda pakati pegirazi simbi mahwendefa ane ndiro inobatirira, woitumira kune vacuum press kuti iomese uye isungirire firimu racho nekudziya kwakakodzera nekumanikidza.Gomba rinonangwa redhidhi redhisheni rakadhindwa neX-ray otomatiki yekumisikidza tarisiro yemuchina wekuchera segomba rekutarisa rekurongeka kwemukati nekunze maseketi.Mupendero weplate uchachekwa zvakachekwa zvakanaka kuti ufambise kugadzirwa kunotevera.
[Kuchera] dhiraivha bhodhi redunhu nemuchina wekuchera weCNC kuti uboore nepaburi redunhu reinterlayer uye gomba rekugadzirisa rezvikamu zvewelding.Pakuchera, shandisa pini kugadzirisa bhodhi redunhu patafura yemuchina wekuchera kuburikidza negomba rakange racherwa, uye wedzera yakadzika yakadzika backing plate (phenolic ester plate kana huni pulp plate) nepamusoro pekuvhara ndiro (aluminium ndiro) kuderedza. kuitika kwekuchera burrs.
[Plated through Hole] mushure mekunge interlayer conduction channel yaumbwa, simbi yemhangura layer icharongwa pairi kuti ipedze kuitisa interlayer circuit.Chekutanga, chenesa bvudzi riri pagomba uye hupfu huri mugomba nekukuya bhurashi rinorema uye high-pressure washing, uye soak uye kuisa tini pacheneswa gomba kumadziro.
[Primary Mhangura] palladium colloidal layer, yobva yaderedzwa kuita simbi palladium.Dare redunhu rinonyudzwa mumushonga wekemikari yemhangura, uye ioni yemhangura mumushonga inoderedzwa uye inoiswa pamadziro egomba ne catalysis ye palladium metal kuti iite kuburikidza-gomba redunhu.Zvadaro, mhangura yemhangura mukati megomba yakakora nemhangura sulfate bath electroplating kusvika kune ukobvu hwakakwana kuti irambe kukanganiswa kweinotevera kugadzirisa uye sevhisi nharaunda.
[Outer Line Secondary Copper] kugadzirwa kwemutsara wekufambisa mufananidzo kwakafanana nemutsara wemukati, asi mukumisikidza mutsara, wakakamurwa kuva nzira dzekugadzira dzakanaka uye dzisina kunaka.Nzira yekugadzira yefirimu yakaipa yakafanana nekugadzirwa kwemukati wedunhu.Inopedzwa nekuisa zvakananga mhangura uye kubvisa firimu mushure mekuvandudzwa.Nzira yekugadzira yefirimu yakanaka ndeyekuwedzera yechipiri mhangura uye tin lead plating mushure mekuvandudzwa (mutobvu wetini munzvimbo ino unozochengetwa sechidziviriro chekudzikisira mune inotevera mhangura etching nhanho).Mushure mokubvisa firimu, iyo yakavharwa yemhangura foil inosvibiswa uye inobviswa nealkaline ammonia uye copper chloride yakasanganiswa mhinduro kuti iite nzira yewaya.Pakupedzisira, shandisa tin lead stripping solution kusvuura tin lead layer yakabudirira kuenda pamudyandigere (mumazuva ekutanga, tin lead layer yaichengetwa uye yaishandiswa kuputira dunhu sechidziviriro chekudzivirira mushure mekunyunguduka, asi ikozvino yakanyanya kunyungudika. isina kushandiswa).
[Anti Welding Ink Text Printing] pendi yekutanga yegirinhi yakagadzirwa nekudziya zvakananga (kana ultraviolet irradiation) mushure mekudhindwa kwescreen kuomesa firimu rependi.Nekudaro, mukudhinda nekuomesa, kazhinji inoita kuti pendi yakasvibira ipinde mukati memhangura yepamusoro yemutsara terminal kusangana, zvichikonzera dambudziko rechikamu welding uye kushandiswa.Iye zvino, kunze kwekushandiswa kwemapuranga akareruka uye akaomarara, anonyanya kugadzirwa ane photosensitive green pendi.
Iwo mameseji, trademark kana chikamu nhamba inodiwa nemutengi ichadhindwa pabhodhi nekudhindwa kwechidzitiro, uye ipapo ingi yependi ichaomeswa nekuomeswa nekupisa (kana ultraviolet irradiation).
[Contact Processing] anti welding yependi yakasvibirira inovhara yakawanda yemhangura yedunhu redunhu, uye chete materminal anobatika echikamu chewelding, bvunzo dzemagetsi uye kuisirwa bhodhi redunhu zvinoburitswa.Yakakodzera yekudzivirira layer ichawedzerwa kune ino yekupedzisira kudzivirira kugadzirwa kweoxide pamagumo ekubatanidza anode (+) mukushandiswa kwenguva refu, inokanganisa kugadzikana kwedunhu uye kukonzera kunetseka kwekuchengetedza.
[Kuumba Uye Kucheka] cheka bhodhi redunhu kuita zviyero zvekunze zvinodiwa nevatengi vane CNC yekuumba muchina (kana kufa punch).Paunenge uchicheka, shandisa pini kugadzirisa bhodhi redunhu pamubhedha (kana mold) kuburikidza negomba rakambodhirwa nzvimbo.Mushure mekucheka, chigunwe chegoridhe chichakuyiwa pakona ye oblique kuti zvive nyore kuisa uye kushandiswa kwebhodhi redunhu.Kune redunhu bhodhi rakaumbwa nemachipisi akawanda, X-yakaumbwa mitsara yekutyora inoda kuwedzerwa kuitira kufambisa vatengi kupatsanura uye kupatsanura mushure meplug-in.Pakupedzisira, chenesa guruva pabhodhi redunhu uye ionic zvinosvibisa pamusoro.
[Kuongorora Bhodhi Packaging] yakajairika kurongedza: PE firimu kurongedza, kupisa kunopisa firimu kurongedza, vacuum kurongedza, nezvimwe.
