Ubunini bwa ENIG plating burinda ingese y'umukara, bubungabunga ubusugire bw'ingingo, kandi bugashyigikira ubushobozi buke bwo guhangana n'ibintu. Nickel kuri 3–6 μm itanga uruzitiro ruhoraho rwo gukwirakwiza uduce tw'umuringa kandi igakomeza inzira z'amashanyarazi, mu gihe zahabu ya 0.05–0.15 μm irinda nikeli kwangirika kugeza igihe ivanze n'ibintu. Gutandukana munsi ya 3 μm nikeli cyangwa zahabu ya 0.05 μm byongera cyane intege nke zo guhura n'ibintu muri PCB zifite ubucucike bwinshi kandi zitoshye.

Incamake y'Inzira yo Gushyiramo Imbunda muri ENIG
Gushyira ENIG mu gitereko bitangirira ku gushyira nikeli idafite amashanyarazi ku dupapuro tw'umuringa, hakoreshejwe uburyo bwa chemical kugira ngo habeho urwego rwa nikeli-fosforusiya rungana. Ubunini bwa nikeli bugira ingaruka zitaziguye ku mbaraga za mekanike no ku buryo amashanyarazi acukurwamo—agaciro kari hanze y’urwego rwa 2.5-7 μm byongera ibibazo byo guterana kandi kagabanye igihe cyo kubaho k'umusaruro. Intambwe ya zahabu yo kwibiramo itwikira nikeli zahabu ya 0.05-0.23 μm binyuze mu kwimura ionic, bigatanga uburyo bwo gutwikira nta kintu na kimwe n'imiterere nyayo y'ingano. Kugenzura igipimo cya nikeli-fosforusiya bigena ubwiza bw'umusozo, mu gihe ubunini bwa zahabu buringaniye burinda kwimuka kwa nikeli kandi bikagabanya ibyago byo kwangirika. Isuzuma rya Lonnmeter LONN-T850 XRF ripima neza urwego rwombi, rituma habaho kugenzura ubuziranenge bwa PCB no kubahiriza amahame y'ubunini bwa ENIG mu gitereko.
Amabwiriza y'ubunini n'intego z'ubuziranenge kuri ENIG
Ubugari bwa nikeli kuri ENIG bugomba kuguma hagati ya 2.5–7 μm kugira ngo buzuze amahame ya IPC-4552B, aho ubwizigirwa bwo hejuru bugera kuri 3.0–6.0 μm. Ubu bwoko bwa nikeli butuma habaho ubushobozi bwo gusoda neza, imbogamizi ihamye yo gukwirakwiza umuringa, no kurwanya ingese neza mu miterere ya PCB ifite ubucucike bwinshi kandi isanzwe. Izahabu yo mu mazi igomba gupima 0.05–0.23 μm, ikarinda nikeli mu gihe ikarinda ingingo zo gusoda zicika; urwego rwa zahabu rusanzwe kandi rwizewe ni 0.05–0.15 μm kugira ngo ikoreshwe mu buryo bwinshi.
Gutandukana n'ibi bipimo by'ubugari bw'icyuma byongera ibyago byo kwangirika. Uduce twa nikeli turi munsi ya 2.5 μm dutera ingese vuba, agapira k'umukara, n'ingingo zisoda zigacika intege. Nikeli nyinshi ishobora gutera imbaraga imbere ariko gake cyane ntishobora gucika mu ntera yagenwe. Indabyo ntoya kurusha 0.05 μm ituma nikeli ishonga, ikagabanya igihe cyo kuyisiga no kuyisoda. Indabyo iri hejuru ya 0.23 μm ituma itose nabi, ishonga cyane, kandi ingingo zitizewe bitewe n'uko zihinduka.
Ubunini bwa ENIG bugenzura neza imiterere y’icyuma gifata nikeli kikajya muri zahabu, bigakomeza kugira ubushobozi bwo guhangana n’ikintu kandi bikarinda ko kidakora neza. Imiterere myiza y’ibinyampeke muri ibyo bice byombi ituma habaho imikorere myiza no kurangiza neza ubuso, bikaba ari ingenzi mu kugira ubushobozi bwo guhangana n’ikintu mu bice bihuza n’icyuma n’ibice bya BGA. Imashini zisesengura za Lonnmeter XRF zikora ku buryo bwikora zipima neza imiterere y’icyuma gifata nikeli na zahabu, zishyigikira aya mabwiriza akomeye y’ubuziranenge mu bipimo byose by’inganda za PCB.
Ibyiza by'ingenzi bya ENIG ku mabwiriza yacapwe
ENIG itanga uburyo bwiza bwo gushyira ibintu mu buryo bunoze kandi bufite ubucucike bwinshi ku mbaho zacapwe. Indabyo ikomeye yongerera ubushobozi bwo gusoda, ikanafasha guhuza neza kandi nta kibazo kirimo. Uduce duto twa nikeli munsi ya zahabu turinda ogisijeni no kwimuka, bikomeza ubudahangarwa bw'ingufu kandi bishyigikira inzira nyinshi zo gusoda. Mu bushakashatsi bwagenzuwe, ENIG PCB irangizwa neza kurusha HASL kuko ikomeza kudakora neza no kuramba neza mu gihe cy'ubushuhe bwinshi n'ubushyuhe bwinshi. Ku nganda zigezweho z'ikoranabuhanga, irangizwa rya ENIG rituma ikoranabuhanga ryo gushyira ku buso rikomeza kwizerwa kandi rikarinda kwangirika kw'ibidukikije.
Gutunganya Uburyo bwawe bwa PCB ukoresheje LONN-T850 XRF Plating Thickness Tester
Ibiranga by'ingenzi bya LONN-T850 XRF Analyzer
Imashini ipima ubunini bwa LONN-T850 XRF ya Lonnmeter ikoresha icyuma gipima ubunini bwa Silicon Drift Detector (SDD) gifite ubushobozi bwo gupima neza imiterere ya nickel-phosphorus na zahabu mu nganda za PCB zacapwe. Iki gikoresho gipima ubunini kugeza kuri nanometers, ni ingenzi cyane kugira ngo cyuzuze amahame ngenderwaho y’ubunini bwa ENIG. Ubuhanga bwo gupima XRF buhuriweho muri LONN-T850 butanga igipimo cyo gukoresha neza imiyoboro y’umusaruro mwinshi, bushyigikira isesengura ry’ingero zigera kuri 300 ku isaha. Gushakisha amakuru vuba bituma habaho uburyo bwo guhita utanga ibitekerezo, bikuraho gutinda gukunze kugaragara mu buryo bwangiza.
Guhuza neza n'imikorere y'inganda za PCB
Ibikoresho byo gutanga raporo byikora byemeza ko buri PCB yapimwe ishobora gukurikizwa, bihuye n'ibisabwa mu kugenzura ubuziranenge mu gushushanya no gukora urubuga rwacapwe. Uburyo bworoshye bwo gukoresha, bwagenewe igihe gito cyo guhugura, bworohereza abakozi bashya n'abahanga bamenyereye gukoresha vuba. Amakuru yose yo gupima ashobora koherezwa mu mahanga kugira ngo agenzurwe neza ibikorwa by'ibarurishamibare no gusuzuma igenzura, byoroshya kubahiriza amabwiriza agenga uburyo bwo gushushanya zahabu idafite amashanyarazi ya nikeli.
Gutanga Ubuhanga mu Kugenzura Imiterere ya ENIG
Gukumira ubusembwa mu buryo bwihuse bigerwaho binyuze mu gushyira ibimenyetso ku binyuranyo mbere yo guteranya, bigafasha kugenzura neza ubuziranenge bwa PCB. Ubushobozi bwa multilayer butuma nickel yimuka icyarimwe kandi bugatuma ingingo zisoda zikomera, birenga uburyo gakondo bwo gupima ubunini bw'ubuso bwa PCB. Ingero zikoreshwa zihera ku gukoresha zahabu idafite amashanyarazi ya nickel mu bikoresho by'ikoranabuhanga kugeza ku kurangiza kwa PCB kwa ENIG ugereranyije na HASL, bitanga ibisubizo bisanzwe kandi byizewe ku nganda zacapwe.
Saba igiciro cya LONN-T850 XRF Analyzer
Itsinda rya serivisi za tekiniki rya Lonnmeter rifasha mu gutanga ibitekerezo byihariye no gushyigikira ibikorwa, kunoza ireme no kongera umusaruro mu bijyanye no gushushanya zahabu ya nikeli ku mbaho z’amashanyarazi. Ifishi yo gusaba serivisi y’ikoranabuhanga ituma habaho ibisubizo byihariye, byoroshya inzira yo gutanga ibiciro ku bahanga n’abaguzi.
Ibibazo Bikunze Kubazwa
Gupima ubugari bwa plating ni iki kandi kuki ari ingenzi kugira ngo PCB ibe iyizerwa?
Gupima ubugari bw'ibice bya platingi bipima urwego rwa nikeli na zahabu ku buso bwa PCB. Ubunini burenze urugero butera kudakoresha neza ibicanwa, bugatera kwangirika kw'udupira tw'umukara, kandi bugatuma zahabu yimuka vuba.
Ni ubuhe bunini busabwa mu gukora PCB mu gushyiramo ENIG?
Amabwiriza y’inganda agaragaza nikeli iri kuri 2.5–7 μm n’izahabu iri kuri 0.05–0.23 μm. Izi ntera zongerera ubushobozi bwo gukoresha neza ibyuma bisoda, zikarinda kwangirika kwa nikeli, kandi zikabuza kwimuka kwa zahabu mu gihe zikagabanya ikoreshwa rya zahabu ritari ngombwa.
