Ukobvu hwe ENIG plating hunodzivirira ngura yemapedhi matema, hunochengetedza kubatana kwe solder, uye hunotsigira kusabatana kwakawanda. Nickel iri pa 3–6 μm inopa chipingamupinyi chinopararira nguva dzose pamapedhi emhangura uye inochengetedza nzira dzemagetsi, nepo 0.05–0.15 μm yegoridhe ichidzivirira nickel kubva mukuoxidation kusvika yasangana. Kutsauka kuri pasi pe 3 μm nickel kana 0.05 μm yegoridhe kunowedzera zvakanyanya kutadza kubatana mumaPCB ane density yakakura, fine-pitch.

Ongororo yeMaitiro ekugadzira ENIG Plating
Kuisa ENIG plating kunotanga nekuiswa kwenickel isina magetsi pamapedhi emhangura, uchishandisa reaction yemakemikari kugadzira nickel-phosphorus layer yakapararira zvakaenzana. Ukobvu hwenickel hunokanganisa zvakananga simba remakanika uye kufambisa magetsi—zviyero zviri kunze kwe2.5–7 μm zvinowedzera kutadza kwekuunganidza uye zvinoderedza hupenyu hwechigadzirwa. Danho regoridhe rekunyudza rinofukidza nickel negoridhe re0.05–0.23 μm kuburikidza ne ionic displacement, zvichipa kufukidza kusina void uye chimiro chakarurama chezviyo. Kudzora chiyero chenickel-phosphorus kunosarudza kunaka kwekupedzisira, nepo ukobvu hwegoridhe hwakafanana hunodzivirira kufamba kwenickel uye kunoderedza njodzi yekuora. Lonnmeter LONN-T850 XRF tester inoyera nemazvo zvidimbu zvese, ichigonesa kudzora kwakasimba kwePCB plating quality uye kutevedzera mitemo yeENIG plating thickness.
Nhungamiro dzeKukora uye Zvinangwa zveHunhu zveENIG
Ukobvu hwenickel plating yeENIG hunofanira kugara mukati me2.5–7 μm kuti isvike pazvinodiwa neIPC-4552B, nekuvimbika kwakanyanya kunowanikwa kubva pa3.0–6.0 μm. Iyi nickel range inoita kuti solder ikwanise kusunganidzwa zvakanaka, chipingamupinyi chakagadzikana chekupararira kwemhangura, uye kudzivirira ngura zvinobudirira mumagadzirirwo ePCB ane density yakakura uye echinyakare. Goridhe rekunyudza rinofanira kuyera 0.05–0.23 μm, richivandudza dziviriro yenickel uku richidzivirira brittle solder joints; goridhe rakajairika uye rakavimbika i0.05–0.15 μm yekushandisa mukugadzirwa kwehuwandu.
Kutsauka kubva pamatanho aya ekukora kweplate kunowedzera njodzi yekukanganisika. Nickel layers dziri pasi pe2.5 μm dzinokonzera ngura nekukurumidza, black pad, uye solder joints dzisina simba. Nickel yakawandisa inogona kukonzera kushushikana kwemukati asi kashoma kuti isashande mukati memiganhu yakatarwa. Goridhe rakatetepa pane 0.05 μm rinogonesa nickel oxidation, zvichikanganisa nguva yekushanda kwayo uye kugona kwayo kusunganidzwa. Goridhe riri pamusoro pe0.23 μm rinotungamira mukunyorova kusina kunaka, goridhe rakanyunguduka zvakanyanya, uye majoints asingavimbike nekuda kwekupwanyika.
Kudzora ukobvu hweENIG kwakakodzera kunomisa kufamba kwe nickel kuenda kugoridhe, zvichichengetedza kuramba kwakasimba uye kudzivirira kutadza kushanda zvakanaka. Maumbirwo ezviyo akakwana muzvikamu zvese zviri zviviri anovimbisa kufambiswa kwemhepo uye kupera kwakafanana kwenzvimbo, zvakakosha kuti isashande zvakanyanya munzvimbo dzinobatanidza uye munzvimbo dzeBGA. Vagadziri veLonnmeter XRF vanogadzira otomatiki vanopa kuyerwa kwakananga kwezvikamu zve nickel negoridhe, vachitsigira nhungamiro idzi dzakasimba dzemhando yepamusoro pamatanho ese ekugadzira maPCB.
Mabhenefiti Akakosha eENIG ePrinted Circuit Boards
ENIG inopa planarity yepamusoro, zvichiita kuti zvive nyore kuisa zvikamu zvakanaka uye zvine density yakawanda pamabhodhi edunhu akadhindwa. Goridhe rakasimba rinosimudzira kugona kusungirirwa, richikurudzira kubatana kwakasimba uye kusina kukanganisa. Nickel layers dzakafanana pasi pegoridhe dzinodzivirira oxidation uye kufamba, dzichisimbisa kuramba kwengura uye dzichitsigira kutenderera kwakawanda kwekusungirirwa. Muzvidzidzo zvinodzorwa, ENIG PCB inopedzisa kupfuura HASL nekuchengetedza kuramba kwakaderera kwekusangana uye kugara kwenguva refu pasi pehunyoro hwakawanda uye kushushikana kwekupisa. Kune zvigadzirwa zvemagetsi zvepamusoro, ENIG finish inowedzera kuvimbika kwetekinoroji yekusungirirwa pamusoro uye inodzivirira kubva mukuora kwezvakatipoteredza.
Kugadzirisa Maitiro EPCB Yako neLONN-T850 XRF Plating Thickness Tester
Zvinhu Zvakanyanya Kunaka zveLONN-T850 XRF Analyzer
Lonnmeter's LONN-T850 XRF plating thickness tester inoshandisa high-resolution Silicon Drift Detector (SDD) kuti inyatsoyera nickel-phosphorus uye gold layers muPCB printed circuit board manufacturing. Iyi detector inoita kuti ukobvu huve hwakarurama kusvika kuma nanometers, zvakakosha kuti isangane ne ENIG plating thickness standards. Matekiniki ekuyera XRF akabatanidzwa muLONN-T850 anopa throughput rates yakakodzera mitsetse yekugadzira yakawanda, achitsigira batch analysis inosvika 300 samples paawa. Kuwana data nekukurumidza kunogonesa mhinduro yekukurumidza, kubvisa kunonoka kunowanzoitika munzira dzinoparadza.
Kubatanidzwa Kwakatsetseka neKushanda Kwekugadzira PCB
Zvinhu zvinoburitswa otomatiki zvinovimbisa kuteverwa kwePCB yega yega yakayerwa, zvichienderana nezvinodiwa zvekudzora mhando mukugadzirwa uye kugadzirwa kwebhodhi redunhu rakadhindwa. Iyi interface iri nyore kushandisa, yakagadzirirwa nguva shoma yekudzidziswa, inobatsira kukurumidza kushandiswa nevashandi vatsva nemainjiniya vane ruzivo. Ruzivo rwese rwekuyera runogona kutumirwa kunze kwenyika kuti rudzore maitiro ehuwandu uye kuongororwa kweaudit, zvichiita kuti zvive nyore kutevedzera zvinodiwa ne electroless nickel immersion gold plating process.
Kupa Hunhu Hwakanaka muENIG Plating Control
Kudzivirira kukanganisa kunoitika nekuisa chiratidzo chekuchinja kusati kwasangana, zvichitsigira kudzora kwakanaka kwePCB plating quality. Kugona kwemuchina uyu we analyzer panguva imwe chete kunodzivirira kufamba kwe nickel uye kunoita kuti ma solder joints arambe akasimba, zvichipfuura nzira dzechinyakare dzekuyera ukobvu hwePCB. Mashandisirwo ekushandisa anosanganisira kushandiswa kwegoridhe risina electroless nickel mumagetsi kusvika ku ENIG vs. HASL PCB finishes, zvichipa mhedzisiro yakajairika uye yakavimbika yekugadzira printed circuit board.
Kumbira Mutengo weLONN-T850 XRF Analyzer
Chikwata chebasa rehunyanzvi cheLonnmeter chinobatsira nekupa mazano akagadzirwa uye rutsigiro rwemaitiro, zvichivandudza kunaka kwemhando uye kuwedzera goho kuburikidza ne nickel gold plating yema circuit boards. Fomu rekukumbira redhijitari rinogonesa mhinduro dzakagadzirwa, zvichiita kuti maitiro ekutenga ave nyore kune mainjiniya nevatengi.
Mibvunzo Inowanzo bvunzwa
Chii chinonzi kuyera ukobvu hweplating uye nei zvichikosha pakuvimbika kwePCB?
Kuyera ukobvu hweplating kunoyera nickel negoridhe pamusoro pePCB. Ukobvu husingawanikwe hunokonzera kusagona kusunganidzwa zvakanaka, hunogona kukonzera ngura, uye hunokurumidza kufamba kwegoridhe.
Ndeapi makobvu anokurudzirwa ekuisa ENIG plating mukugadzirwa kwePCB?
Mitemo yeindasitiri inotaura nezve nickel pa 2.5–7 μm uye goridhe pa 0.05–0.23 μm. Mhando idzi dzinowedzera kuvimbika kwemajoini e solder, dzinodzivirira ngura ye nickel, uye dzinodzivirira kufamba kwegoridhe uku dzichideredza kushandiswa kwegoridhe zvisina kufanira.
