Iko kukosha kwekubuda kweglobal electroplating PCB indasitiri inotora kukurumidza kuwedzera kwechikamu chehuwandu hwekubuda kukosha kweindasitiri yechikamu chemagetsi. Ndiyo indasitiri ine chikamu chikuru mune zvemagetsi chikamu indasitiri uye inobata chinzvimbo chakasiyana. Iko kukosha kwegore negore kwe electroplated PCB inosvika mabhiriyoni makumi matanhatu emadhora ekuAmerica. Kuwanda kwezvigadzirwa zvemagetsi kuri kuita kureruka, kutetepa, kupfupika uye kudiki, uye kunanga kuturikidzana kwevias pamapofu inzira yekugadzira kuwana hukama hwepamusoro-density. Kuti uite basa rakanaka rekuisa makomba, pasi pegomba panofanira kunge rakatsetseka. Pane nzira dzakati wandei dzekugadzira yakajairwa gomba repamusoro, uye iyo electroplating gomba yekuzadza nzira ndeimwe yevamiriri. Pamusoro pekudzikisa kudiwa kwekuwedzera kwekuvandudza maitiro, iyo electroplating uye kuzadza maitiro inoenderana neazvino maitiro emidziyo, iyo inobatsira kuwana kuvimbika kwakanaka.

Electroplating gomba kuzadza kune zvinotevera zvakanakira:

(1) Inobatsira kugadzirwa kwemakomba akaturikidzana (Akaturikidzwa) uye pa-disk maburi (Via.on.Pad);

(2) Kuvandudza kushanda kwemagetsi uye kubatsira high-frequency design;

(3) Kubatsira pakupisa 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 pesimba parameters

Iwo emuviri maparamendi anoda kudzidzwa ndeaya: anode type, anode-cathode spacing, ikozvino density, agitation, tembiricha, rectifier uye waveform, nezvimwe.

(1) Anode type. Kana zvasvika kune anode marudzi, hapana chimwe chinopfuura soluble anodes uye insoluble anodes. Anode inonyungudika kazhinji ibhora remhangura yephosphorous, iri nyore kugadzira anode dope, kusvibisa mhinduro yeplating, uye kukanganisa kushanda kwemushonga weplating. Insoluble anodes, inozivikanwawo seinert anodes, inowanzo umbwa netitanium mesh yakavharwa neakasanganiswa oxides etantalum uye zirconium. Insoluble anode, kugadzikana kwakanaka, hapana anode kuchengetedza, hapana anode mud chizvarwa, pulse kana DC electroplating inoshanda; zvisinei, kushandiswa kwezvinowedzera zvakakura.

(2) Chinhambwe pakati pecathode neanode. Dhizaini yepakati pakati pe cathode uye anode mu electroplating gomba rekuzadza nzira yakakosha, uye dhizaini yemhando dzakasiyana dzemidziyo haina kufanana. Zvisinei, inofanira kutaurwa kuti pasinei nokuti yakagadzirwa sei, haifaniri kutyora mutemo wekutanga waFara.

3) Kukurudzira. Kune marudzi akawanda ekukurudzira, kusanganisira mechanical kuzununguka, kuzunguza kwemagetsi, kuzunguza kwemhepo, kubvongodza mhepo, uye jet (Eductor).

Kune electroplating uye maburi ekuzadza, inowanzo farira kuwedzera jet dhizaini zvichienderana nekugadziriswa kwechinyakare mhangura silinda. Zvisinei, ingave iri pasi jet kana jet side, nzira yekuronga jet tube 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 jet yepasi yakashandiswa, inokonzera kusaenzana kusanganisa, uye kugadzirisa kweplating kuchamutswa kusina simba uye kusimba pasi; nhamba, nzvimbo, uye kona yejeti pajeti chubhu zvinhu zvose zvinofanirwa kutariswa pakugadzira humburumbira yemhangura. Kuedza kwakawanda kunodiwa.

Uye zvakare, iyo yakanyanya kunaka nzira ndeyekubatanidza yega jet chubhu kune inoyerera mita, kuitira kuti uwane chinangwa chekutarisa chiyero chekuyerera. Nekuti kuyerera kwejeti kwakakura, mhinduro iri nyore kugadzira kupisa, saka kutonga kwekushisa kwakakoshawo.

(4) Yazvino density uye tembiricha. Yakaderera ikozvino density uye yakaderera tembiricha inogona kuderedza pamusoro pemhangura deposition rate, uku ichipa yakakwana Cu2 uye inopenya mugomba. Pasi pemamiriro ezvinhu aya, kugona kuzadza gomba kunowedzerwa, asi panguva imwechete iyo plating inoshanda yakaderedzwa.

(5) Mugadzirisi. Iyo inogadzirisa chinhu chakakosha chinongedzo mune electroplating process. Parizvino, tsvagiridzo yekuzadza gomba re electroplating inongogumira kune yakazara plate electroplating. Kana iyo pateni electroplating gomba kuzadza ikatariswa, nzvimbo yecathode ichava diki kwazvo. Panguva ino, zvinodikanwa zvakakwirira kwazvo zvinoiswa kumberi kwekubuda chaiko kweanogadzirisa.

Iko kurongeka kweiyo rectifier kunofanirwa kusarudzwa zvinoenderana nemutsara wechigadzirwa uye saizi yeVia. Iyo yakatetepa mitsetse uye madiki maburi, inokwidza iyo yechokwadi zvinodiwa zveanogadzirisa. Kazhinji, rectifier ine kubuda kwechokwadi kweisingasviki 5% inofanira kusarudzwa. Iko kurongeka kwepamusoro kweiyo yakasarudzwa inogadzirisa ichawedzera mari yekushandisa. Kune inobuda tambo wiring yeinogadzirisa, tanga isa chinogadzirisa padivi petangi replating zvakanyanya sezvinobvira, kuitira kuti hurefu hwetambo yekubuda hugone kuderedzwa uye iyo pulse ikozvino yekusimuka nguva inogona kuderedzwa. Kusarudzwa kweiyo inogadzirisa inobuda tambo yakatarwa inofanirwa kugutsa kuti mutsara wevoltage inodonha yetambo yekubuda iri mukati me0.6V kana iyo yakanyanya kubuda ikozvino iri 80%. Iyo inodiwa cable cross-sectional area inowanzoverengwa maererano nezvino-kutakura simba re 2.5A / mm:. Kana iyo mhiri-chikamu nzvimbo yetambo idiki zvakanyanya kana kureba kwetambo yakarebesa, uye mutsara wemagetsi unodonha wakakurisa, iyo yekufambisa yazvino haisvike kukosha kwazvino kunodiwa pakugadzirwa.

Kune matangi ekuputira ane groove yakafara kupfuura 1.6m, nzira yemagetsi yemativi maviri inofanira kutariswa, uye kureba kwetambo dzemativi maviri kunofanirwa kuenzana. Nenzira iyi, inogona kuve nechokwadi kuti iyo bilateral ikozvino kukanganisa inodzorwa mukati meimwe siyana. Iyo inogadzirisa inofanirwa kubatanidzwa kune yega yega flybar ye plating tank, kuitira kuti ikozvino pamativi maviri echimedu inogona kugadziridzwa zvakasiyana.

(6) Waveform. Parizvino, kubva pakuona kwemasaveforms, kune marudzi maviri ekuzadza gomba remagetsi: pulse electroplating uye DC electroplating. Zvose electroplating uye nzira dzekuzadza dzakadzidzwa. Iyo yakananga ikozvino electroplating gomba yekuzadza inotora iyo yechinyakare rectifier, iri nyore kushanda, asi kana ndiro yakakora, hapana chinogona kuitwa. Pulse electroplating gomba kuzadza kunoshandisa PPR rectifier, iyo ine akawanda nhanho ekushanda, asi ine yakasimba kugadzirisa kugona kweakakora mu-process board.

Kufurira kwe substrate

Kufuridzira kwe substrate pane electroplated gomba kuzadza hakufaniriwo kuregererwa. Kazhinji, pane zvinhu zvakaita se dielectric layer material, gomba chimiro, ukobvu-kusvika-diameter reshiyo, uye kemikari yemhangura plating.

(1) Chigadzirwa cheiyo dielectric layer. Izvo zvinyorwa zve dielectric layer zvine mhedzisiro pagomba rekuzadza. Kuenzaniswa negirazi fiber reinforced materials, isiri-girazi yakasimbiswa zvinhu zviri nyore kuzadza makomba. Zvakakosha kucherechedza kuti girasi fiber protrusions mugomba ine mhedzisiro yakaipa pamakemikari emhangura. Muchiitiko ichi, kuoma kwe electroplating kuzadza gomba ndiko kuvandudza kusungirirwa kwembeu yembeu ye electroless plating layer, panzvimbo yegomba rekuzadza iyo pachayo.

Muchokwadi, electroplating uye kuzadza maburi pagirazi fiber reinforced substrates yakashandiswa mukugadzira chaiko.

(2) Hukobvu kune dhayamita reshiyo. Parizvino, vese vanogadzira uye vanogadzira vanoisa kukosha kukuru kune tekinoroji yekuzadza makomba emhando dzakasiyana uye saizi. Iko kugona-kuzadza gomba kunokanganiswa zvakanyanya negomba ukobvu-kusvika-dhayamita reshiyo. Zvichienderana, DC masisitimu anoshandiswa zvakanyanya kutengeserana. Mukugadzira, saizi yegomba ichave yakatetepa, kazhinji 80pm～120Bm mudhayamita, 40Bm～8OBm pakadzika, uye reshiyo yekukora kusvika kudhayamita haifanire kudarika 1:1.

(3) Electroless copper plating layer. Ukobvu uye kufanana kwe electroless copper plating layer uye nguva yekuisa mushure me electroless copper plating zvese zvinokanganisa gomba rekuzadza kuita. Iyo electroless mhangura yakanyanya kutetepa kana kusaenzana mukukora, uye gomba rayo rekuzadza gomba harina kunaka. Kazhinji, zvinokurudzirwa kuzadza gomba kana ukobvu hwekemikari mhangura iri> 0.3pm. Mukuwedzera, iyo oxidation yekemikari mhangura inewo kukanganisa kwakashata pagomba rekuzadza gomba.
