Kungani i-ENIG PCB Manufacturing Ilungele Izicelo Zemvamisa Ephakeme

Njengomgogodla wezinto zikagesi zesimanje, ama-PCB abalulekile ekusebenzeni kwemishini kagesi. Phakathi kokuqedwa okuhlukahlukene okusetshenziselwa ama-PCB, i-Electroless Nickel Immersion Gold (ENIG) yaziwa kabanzi ngokusebenza kwayo okukhethekile nokwethembeka. I-Highleap Electronic ikhiqiza ama-PCB e-ENIG anekhwalithi ephezulu, izindleko eziphansi, ukusebenza okuzinzile, namandla okukhiqiza ububanzi bomugqa ongu-2/2mil kanye ne-pitch ENIG PCB. Kulesi sihloko, sizocubungula izinqubo eziwumongo zokukhiqiza i-ENIG PCB, sigqamise izinzuzo zayo, sihlole izinselelo, futhi sichaze ukuthi kungani ihlala iyinketho ephezulu ezimbonini eziningi, kusukela kubathengi be-electronics kuya kwi-aerospace.

Iyini i-ENIG (Electroless Nickel Immersion Gold)?

I-ENIG, emele i-Electroless Nickel Immersion Gold, iyindawo engaphezulu esebenza ngempumelelo esetshenziswa ekukhiqizeni i-PCB. Iqukethe izendlalelo ezimbili ezihlukene: ungqimba lwe-nickel olulandelwa ucwecwe oluncane lwegolide. Umsebenzi oyinhloko walezi zendlalelo ukuvikela ithusi elingaphansi ekufakweni kwe-oxidation kuyilapho uhlinzeka ngendawo ethembeke kakhulu yezingxenye ze-soldering.

Ngaphezu kokuvikela i-PCB ekugqwaleni nasekulimaleni kwemishini, isiphetho se-ENIG siqinisekisa ukudayiswa okuhle kakhulu, ukuguquguquka kukagesi, nokuzinza kokushisa, okuyenza ifaneleke kakhulu izingxenye zephimbo elihle kanye nezicelo zamafrikhwensi aphezulu.

Inqubo ye-ENIG: Izigaba ezinemininingwane Zokukhiqiza

Inqubo ye-ENIG ibandakanya izigaba ezimbalwa ezibalulekile okufanele zilawulwe ngokucophelela ukuze kuqinisekiswe ukuqedwa kwekhwalithi ephezulu. Lapha, sihlahlela isigaba ngasinye ngokuningiliziwe:

1. PCB Surface Ukulungiselela

Ngaphambi kokuba noma yikuphi ukucwenga kwenzeke, indawo yethusi ye-PCB kufanele ilungiswe kahle. Lokhu kuhilela ukuhlanzwa, ukucwiliswa okuncane, nokusebenzisa ithusi ukuze kuqinisekiswe ukunamathela okufanele kongqimba lwe-nickel. Ukungcola okufana nokungcola okuphilayo kanye ne-oxidation kususwa ngezixazululo zokuhlanza i-alkaline. Ngemva kwalokho, indawo yethusi igxilwa kancane ukuze kwakheke ukuthungwa okuqinile, okuthuthukisa ukunamathela kongqimba lwe-nickel.

2. I-Nickel Deposition (I-Electroless Nickel)

Esinyathelweni sokucwenga i-nickel engenawo ugesi, ingxubevange ye-nickel-phosphorus ifakwa endaweni yethusi kusetshenziswa inqubo yokunciphisa amakhemikhali. Lokhu kucwecwa kwenziwa ngaphandle kokusetshenziswa kwamandla kagesi, okwenza kube kuhle kumajiyometri ayinkimbinkimbi kanye nezindawo ezingewona ama-conductive. I-nickel isebenza njengesithiyo sokuvikela ithusi elingaphansi, ivimbela i-oxidation kanye nokugqwala ngesikhathi sokuphila kwe-PCB.

Ngokuvamile, ubukhulu bengqimba ye-nickel busukela kuma-microns angu-3-7. Okuqukethwe kwe-phosphorus ku-nickel kungahluka phakathi kuka-2% no-14%, okuthinta ukumelana nokugqwala kokuqeda. Amazinga aphezulu e-phosphorus aholela ekwenyukeni kokumelana nokugqwala kanye nokungagugi, kanti amazinga aphansi e-phosphorus athuthukisa ukubola.

3. Ukucwiliswa Igolide Deposition

Ukulandela i-nickel plating, i-PCB icwiliswa kwisisombululo esiqukethe ama-ion egolide. Le nqubo yokucwiliswa kwegolide iwukugudluka, lapho ama-athomu egolide athatha indawo yama-athomu e-nickel angaphezulu, akhe ungqimba oluncane lwegolide olufana nolunye. Ungqimba lwegolide lokucwiliswa ngokuvamile luphakathi kwama-micrometer angu-0.05-0.23 ubukhulu.

Lolu ngqimba lwegolide lufeza izinjongo ezimbalwa ezibalulekile:

• Ukuvikelwa kokugqwala: Igolide limelana kakhulu ne-oxidation, iqinisekisa ukuthi i-PCB igcina ukusebenza kwayo ngokuhamba kwesikhathi, ikakhulukazi ezindaweni ezinokhahlo.
• Ukumelana nokuxhumana okuphansi: Isendlalelo segolide sithuthukisa ukusebenza kukagesi kwe-PCB ngokuhlinzeka ngendawo yokuxhumana ezinzile futhi engamelani nenqubo yokuhlanganisa.
• I-Solderability: Isendlalelo segolide sithuthukisa ukuthengiswa kwe-PCB, okwenza kube lula ukufeza amalunga athembekile e-solder ngesikhathi somhlangano.

4. Ukuhlanza, Ukomisa, kanye Nokuhlolwa Kwekhwalithi

Uma inqubo yokucwiliswa kwegolide isiqediwe, i-PCB iyahlanzwa ukuze isuse noma imaphi amakhemikhali ayinsalela. I-PCB bese yomiswa, futhi ukuhlolwa kokulawulwa kwekhwalithi kuyenziwa ukuze kuqinisekiswe ukuthi isiphetho sihlangabezana nazo zonke izindinganiso ezidingekayo. Lokhu kufaka phakathi ukuhlolwa okubonakalayo kokufana nokuhlolwa kokunamathela ukuze kuqinisekiswe ukuthi izendlalelo ze-nickel nezegolide ziboshwe ngokuvikelekile.

Izinzuzo ezibalulekile ze-ENIG Surface Finish

I-ENIG inikezela ngezinzuzo ezimbalwa ezihlukile kunezinye iziqephu ze-PCB, eziyenza ibe inketho ekhethwayo ezinhlelweni eziningi ezisebenza kahle kakhulu.

1. Superior Surface Planarity

Enye yezinzuzo eziphawuleka kakhulu ze-ENIG ukuhleleka kwayo okuyingqayizivele kwendawo. Ingaphezulu elibushelelezi neliyisicaba libalulekile lapho uhlanganisa izingxenye zephimbo elihle. I-ENIG iqinisekisa ukuthi izingxenye ezifana ne-Ball Grid Arrays (BGAs) kanye namaphakheji e-chip-on-board (COB) zenza ukuthintana okuthembekile kukagesi, kunciphisa amathuba okuba nokukhubazeka kokusoda njengamajoyinti abandayo e-solder.

2. Ukuqina Okuphezulu Nokuphila Isikhathi Eside

I-ENIG yaziwa ngempilo yayo yeshelufu ende kanye nokuqina. Isendlalelo se-nickel sinikeza indawo eqinile, engagugi, kuyilapho ungqimba lwegolide lunikeza isivikelo ku-oxidation kanye nokugqwala. Lezi zici zenza i-ENIG ibe inketho efanelekile yama-PCB asetshenziswa ezindaweni ezinokhahlo, njengalezo ezitholakala ku-aerospace, izimoto, kanye nogesi wezokwelapha.

3. Ukuhambisana Kokubili Ukusoda Okungaholeli Nokungaholeli Okusekelwe Umthofu

I-ENIG ihambisana ngokugcwele nazo zombili izinqubo zokudambisa ezingenamthofu nezisekelwe kumthofu, okuyenza ibe nezinto ezihlukahlukene kakhulu. Lokhu kuvumelana nezimo kubaluleke kakhulu njengoba imboni iqhubekela phambili ekuthobeleni i-RoHS kanye nezinqubo zokukhiqiza ezinobungani nemvelo. I-ENIG iqinisekisa amajoyinti e-solder athembekile kuzo zombili izimo, okwenza kube ukukhetha okuhle kakhulu kubakhiqizi abadinga ukuhambisana nezindinganiso zamazwe ngamazwe.

4. Ukusebenza Kahle Kagesi

I-ENIG ithandwa ngenxa yokumelana kwayo okuphansi kokuxhumana kanye nokusebenza okuphezulu, iqinisekisa ukulahleka kwesignali okuncane ezinhlelweni ezisebenza kakhulu. Lokhu kubaluleke kakhulu emikhakheni efana nezokuxhumana, izinhlelo zokusebenza ze-RF (ifrikhwensi yomsakazo), namandla kagesi, lapho ukusebenza kahle kukagesi kubaluleke kakhulu.

5. I-Solderability Ethuthukisiwe

Ungqimba oluncane lwegolide lwe-ENIG luthuthukisa ukuthengiselana kwe-PCB. Iqinisekisa ukuthi amalunga e-solder akha ngendlela enokwethenjelwa, enciphisa amathuba okuhlangana okubandayo kwe-solder kanye nebhuloho. Lokhu kubaluleke kakhulu kubuchwepheshe be-surface mount technology (SMT) kanye nobuchwepheshe be-chip-on-board (COB), lapho ikhwalithi yamalungu e-solder ithinta ngokuqondile ukusebenza nokuphila isikhathi eside komkhiqizo wokugcina.

Ukuqhathanisa i-ENIG Nenye I-PCB Surface Finishes

Ukuze uqonde kangcono inani le-ENIG, ake siyiqhathanise nezinye ezivamile ze-PCB surface finishes:

• I-HASL : Nakuba i-HASL ingabizi kakhulu futhi inikeza ukushintshwa okuhle, ayinawo uhlaka oludingekayo lwezingxenye ze-fine-pitch. Ukuphela kwe-HASL okusekelwe ku-lead kungaba yinkinga nasezisetshenzisweni zemvamisa ephezulu, lapho indawo elukhuni ingabangela ukuphazamiseka kwesignali.

• I-OSP : I-OSP iyindlela ehlukile eshibhile kune-ENIG, inikeza isembozo esivikelayo phezu kobuso bethusi. Kodwa-ke, inikeza ukumelana okuncane kwe-oxidation futhi ayifaneleki ezindaweni ezidinga ukuqina kwesikhathi eside, njengasezinhlelweni zempi noma zezokwelapha.

• Isiliva Esicwilisiwe (ImAg) : Njenge-ENIG, i-ImAg inikeza ukushintshwa okuhle kanye nokuhleleka kwendawo. Kodwa-ke, i-ImAg isengozini enkulu yokungcoliswa kanye nokushiswa ngokuhamba kwesikhathi, okwenza ingathembeki kangako ekusetshenzisweni ngezidingo zesikhathi eside.
