Iko kukosha kweiyo yepasi rose electroplating PCB indasitiri yakura nekukurumidza muhuwandu hwekubuda kukosha kweindasitiri yechikamu chemagetsi.Ndiyo indasitiri ine chikamu chikuru mune zvemagetsi chikamu chekugovera indasitiri uye inogara yakasarudzika.Iko kukosha kwegore negore kwe electroplating PCB inosvika mabhiriyoni makumi matanhatu emadhora ekuAmerica.The Vhoriyamu zvigadzirwa zvemagetsi ari kuwedzera kuonda uye pfupi, uye zvakananga stacking vias pamusoro kuburikidza-bofu vias inzira yekugadzira kuwana mukuru-density interconnection.Kuti uite gomba rakanaka rekuisa, kutanga kwezvose, flatness yegomba pasi inofanira kuitwa zvakanaka.Pane nzira dzakati wandei dzekugadzira yakajairwa gomba repamusoro, uye iyo electroplating gomba yekuzadza nzira inomiririra imwe. Pamusoro pekudzikisira kudiwa kwekuwedzera kwekuvandudza maitiro, iyo electroplating uye gomba rekuzadza nzira inopindirana neazvino maitiro emidziyo, iyo inobatsira kuwana kuvimbika kwakanaka. Electroplating gomba kuzadza kune zvinotevera zvakanakira: (1) Zvinobatsira kugadzira Stacked uye Via.on.Pad ( HDI Circuit Board ); (2) Kuvandudza kushanda kwemagetsi uye rubatsiro high-frequency design ; (3) Inobatsira kubvisa kupisa; (4) Iyo plug gomba uye yekubatanidza magetsi inopedzwa mune imwe nhanho; (5) Mabofu maburi akazadzwa ne electroplated mhangura, iyo ine yakakwirira kuvimbika uye nani conductivity pane conductive guruu.
Muviri Kufurira Parameters Iwo emuviri maparamita anofanirwa kudzidzwa ndeaya: anode type, cathode-anode spacing, yazvino density, agitation, tembiricha, rectifier uye waveform, nezvimwe. (1) Anode type.Kana zvasvika kune anode marudzi, hachisi chinhu chinopfuura soluble anodes uye insoluble anodes.Soluble anodes anowanzo phosphorus-ine mabhora emhangura, ayo ari nyore kugadzira anode slime, anosvibisa plating solution, uye anokanganisa kushanda kweiyo plating solution.Insoluble anodes, inozivikanwawo seinert anodes, inowanzo sanganisira titanium mesh yakavharwa neokisidhi yakasanganiswa yetantalum uye zirconium.Insoluble anode, kugadzikana kwakanaka, hapana anode kugadzirisa, hapana anode sludge, yakakodzera kupuruzira kana DC electroplating;zvisinei, kushandiswa kwezvinowedzera zvakakura. (2) Chinhambwe pakati pecathode neanode.Dhizaini yepakati pakati pecathode uye anode mune electroplating kuburikidza nekuzadza maitiro yakakosha, uye dhizaini yemhando dzakasiyana dzemidziyo zvakare yakasiyana.Zvisinei, zvinofanira kutaurwa kuti pasinei nokuti yakagadzirwa sei, haifaniri kutyora mutemo wekutanga waFara. (3) Kukurudzira.Kune akawanda marudzi ekukuchidzira, akadai semakanika kuzununguka, kudengenyeka kwemagetsi, kuzunguzika kwegasi, kubvongodza mhepo, Mudzidzisi zvichingodaro. Kune electroplating uye kuzadza, inowanzofarirwa kuwedzera jet dhizaini zvichienderana nekugadziriswa kwechinyakare mhangura silinda.Zvisinei, ingave iyo jet yepasi kana jet yedivi, nzira yekuronga jet chubhu uye mhepo inokurudzira chubhu muhumburu;chii chinonzi jet kuyerera paawa;chii chinhambwe pakati pejet tube uye cathode;kana jet yedivi yakashandiswa, jeti iri pane anode Front kana kumashure;kana jeti yepasi yakashandiswa, ichaita kuti kusaenzana kubvongodze, uye chigadziro cheplating chichave chisina kusimba chinosimudzwa kumusoro uye pasi;Kuita bvunzo yakawanda. Uye zvakare, iyo yakanyanya kunaka nzira ndeyekubatanidza yega jet chubhu kune inoyerera mita, kuitira kuti uwane chinangwa chekutarisa kuyerera.Nekuda kwekuyerera kwejeti hombe, mhinduro yacho inopisa, saka kutonga kwekushisa kunokosha zvakare. (4) Yazvino density uye tembiricha.Yakaderera ikozvino density uye yakaderera tembiricha inogona kuderedza deposition chiyero chepamusoro mhangura, uku ichipa yakakwana Cu2 uye inopenya mugomba.Pasi pemamiriro aya, gomba rekuzadza gomba rinowedzerwa, asi kushanda kweplating kunoderedzwa zvakare. (5) Mugadzirisi.Iyo inogadzirisa chinhu chakakosha chinongedzo mune electroplating process.Parizvino, tsvagiridzo ye electroplating uye kuzadza inongogumira kune yakazara-bhodhi electroplating.Kana iyo muenzaniso electroplating uye kuzadza ichifungidzirwa, iyo cathode nzvimbo ichava diki kwazvo.Panguva ino, zvinodiwa zvakakwirira zvinoiswa kumberi kwekubuda chaiko kwemugadzirisi. Kusarudzwa kweiyo inobuda chaiyo yeinogadzirisa inofanirwa kutariswa zvinoenderana nemutsara wechigadzirwa uye saizi yeiyo via gomba.Iyo yakatetepa mitsetse uye madiki maburi, iyo yakakwirira iyo yechokwadi zvinodiwa zvemugadziri anofanira kunge ari.Kazhinji, zvinokurudzirwa kusarudza rectifier ine kubuda kwechokwadi mukati me5%.Kusarudza rectifier iyo yakanyanya kujeka kuchawedzera mari mumidziyo.Paunenge uchiisa waya yekubuda tambo yeinogadzirisa, tanga isa iyo yekugadziridza pamucheto wetangi yeplating zvakanyanya sezvinobvira, izvo zvinogona kuderedza kureba kwetambo yekubuda uye kuderedza nguva yekusimuka kwepulse ikozvino.Sarudzo yeinogadzirisa inobuda tambo yakatarwa inofanirwa kusangana nemutsara wevoltage kudonha kwetambo inobuda mukati me 0.6V pa80% yeiyo yakanyanya kubuda ikozvino.Kazhinji, iyo inodiwa cable cross-sectional nzvimbo inoverengerwa zvichienderana neazvino kutakura kugona kwe2.5A/mm:.Kana iyo yepakati-chikamu nharaunda yetambo yakanyanya kudiki, kureba kwetambo yakarebesa, kana mutsara wevoltage inodonha yakakura kwazvo, iyo yekufambisa ikozvino haisviki kukosha kwazvino kunodiwa pakugadzirwa. Kune tangi yekuputira ine hupamhi hwetangi yakakura kupfuura 1.6m, nzira yekudyisa magetsi maviri inofanirwa kutariswa, uye kureba kwetambo mbiri kunofanirwa kuenzana.Nenzira iyi, iyo bilateral ikozvino kukanganisa inogona kuvimbiswa kudzorwa mukati meimwe siyana.Inogadzirisa inofanira kubatanidzwa kumativi ose maviri eflybar yega yega tangi yekuputira, kuitira kuti ikozvino pamativi maviri echidimbu inogona kugadziriswa zvakasiyana. (6) Waveform.Parizvino, kubva pakuona waveform, kune marudzi maviri e electroplating nekuzadza: pulse electroplating uye DC electroplating.Idzi nzira mbiri dze electroplating uye kuzadza gomba dzakadzidzwa.Iyo yechinyakare inogadzirisa inoshandiswa kuDC electroplating uye kuzadza gomba, iri nyore kushanda, asi kana ndiro yacho yakakora, hapana chingaitwa.PPR rectifier inoshandiswa pulse electroplating uye gomba kuzadza, iyo ine akawanda nhanho oparesheni, asi ine yakasimba kugadzirisa kugona kweakakora mu-process board.
Kufurira kwe substrate Kufuridzirwa kwe substrate pa electroplating uye kuzadza gomba hakugoni kuregererwa.Kazhinji, pane zvinhu zvakaita se dielectric layer material, hole shape, aspect ratio, uye kemikari copper plating. (1) Dielectric layer zvinhu.Izvo zvinyorwa zve dielectric layer zvine mhedzisiro pakuzadza gomba.Kwete-girazi reinforcements zviri nyore kuzadza makomba pane girazi fiber reinforcements.Zvinokosha kucherechedza kuti girazi fiber protrusions mugomba ane zvinokanganisa makemikari mhangura.Muchiitiko ichi, kuoma kwekuzadzwa kwegomba re electroplating ndiko kuvandudza kunamatira kweiyo electroless plating seed layer, pane iyo gomba rekuzadza iyo pachayo. Muchokwadi, electroplating uye kuzadza maburi pagirazi fiber reinforced substrates yakashandiswa mukugadzirwa chaiko. (2) Aspect ratio.Parizvino, tekinoroji yekuzadza gomba yemakomba emhando dzakasiyana uye saizi inokosheswa nevaviri vanogadzira uye vanogadzira.Kugona kuzadza gomba kunokanganiswa zvakanyanya nehupamhi hwegomba kusvika kudhayamita reshiyo.Zvichienderana, DC masisitimu anoshandiswa zvakanyanya kutengeserana.Mukugadzira, saizi yegomba ichave yakatetepa, kazhinji dhayamita i80pm ~ 120Bm, gomba kudzika kuri 40Bm ~ 8OBm, uye ukobvu-dhayamita reshiyo haipfuure 1: 1. (3) Electroless copper plating layer.Ukobvu uye kufanana kwe electroless copper plating layer uye nguva yekumira mushure me electroless copper plating zvese zvinokanganisa gomba rekuzadza kuita.Electroless mhangura yakatetepa kana kuti ine ukobvu husina kuenzana, uye gomba rayo rekuzadza gomba harina kunaka.Kazhinji, zvinokurudzirwa kuzadza makomba kana ukobvu hwekemikari mhangura iri> 0.3pm.Mukuwedzera, iyo oxidation yekemikari mhangura inewo kukanganisa kwakashata pagomba rekuzadza gomba.
