1. Dab tsi yog qhov sib txawv ntawmKub Platingthiabkev raus dejHauv PCB?
Sinking Kub thiab Kub plating yog ob cov txheej txheem kho hauv qab kev kho hauv pcb, nrog lub ntsiab sib txawv raws li hauv qab no:
Tsim txoj kev: Deposition ntawm Nickel Txheej (anti-oxidation) thiab kub txheej ntawm tooj liab substrate los ntawm kev tawm tsam oxidation; Kub plating yog tiav ncaj qha los ntawm electrolysis, nrog ib daim txheej kub nyias (feem ntau yog 0.05-0.1 μ m).
Kev ua yeeb yam sib txawv: Qhov tso nyiaj kub yog tuab dua (0.1-) Kub plating muaj cov hnav zoo dua (ntxig thiab tshem tawm lub neej ntau dua lossis sib npaug rau 5000 zaug kom tau kub dua (txog 260 degree).
Daim Ntawv Thov Kev Ua Yeeb Yam: Cov Kub Tog Kub yog siv rau high-precision PCBbs (flatness tsawg dua lossis sib npaug ntawm 0.2 μ mg khoom siv; Kub plating yog haum rau cov ntsaws nruab nrab xws li kub ntiv tes (sib chwv tiv taus<10m Ω), ensuring high-frequency connection stability.
Yuav xaiv li cas?
Tus nqi thiab cov txheej txheem ua nyuaj
Tus nqi ntawm Socking Kub yog tus nqi siab (feem ntau yog vim muaj cov nyiaj ntau), thiab nws kuj yuav tsum tiv thaiv lub "dub disk disk".
Kub plating noj cov nyiaj ntau dua ntawm kub thiab yog haum rau kev tsim khoom loj.
Tsim txoj kev
Kev tso nyiaj kub tsuas yog ua tiav los ntawm kev phiv tshuaj oxidation-txo cov kev cuam tshuam, qhov chaw kub atoms hloov lub tooj liab saum npoo los ua txheej.
Kub plating yog cov txheej txheem uas siv electroplating kom npog cov tooj liab nrog lub npib tsib xee kub txheej los ntawm cov khoom siv hluav taws xob electrochemical.
Vuam Performance
Cov kub-plated nto yog smoother thiab tsawg tshaj rau virtual soldering thaum soldering, xws li ua kom muaj cov cim tseem ceeb (xws li BGA ntim khoom siv).
Kub plating, vim nws lub siab hardness thiab zoo cua sov dissipation kev ua tau zoo, xav tau ntau tshav kub disdering ntawm lub cuab yeej (tshwj xeeb yog phau ntawv soldering los ntawm cov tib neeg).
Nyob rau hauv cov nqe lus ntawm thickness, cov yam ntxwv ntawm cov txheej kub yog qhov tso nyiaj kub, thaum lub kub-plated txheej yog thicker (hauv qab 0.05um) thiab muaj xim sib dua. Cov khoom antioxidant ntawm ob qho tib si yog qhov zoo dua rau cov ntawv tso nyiaj kub, thaum kub plating yog ntau tshaj kis oxidation.
Kev Tshaj Tawm Hloov Ntsuas Kev Mob
Vim yog qhov tseeb tias cov tso nyiaj kub tsuas muaj cov txheej kub ntawm cov hlua kub, theoretically cov nqaij tawv yuav me dua.
Kub plating yuav cuam tshuam nrog cov cim high-zaus vim muaj cov khoom sib nqus ntawm cov khoom noj npib tsib xee, thiab yuav tsum tau siv nrog kev ceev faj hauv RF teb.
Piv rau qhov yooj yim kub, kub plating tau hnav ntau dua, thiab kub plating tshuab yog siv rau ntau cov ntiv tes lossis cov ntiv tes.
Cov Kev Xaiv Xaiv
Rau cov laug cam siab, xws li BGA pob nrog ib qho kev sib nrug ntawm tsawg dua 0.5 hli, nws raug pom zoo kom xaiv cov kem imagersion.
Thaum ntau qhov vuam lossis ntev lub sijhawm yog yuav tsum tau (piv txwv li oxidation tsis kam), nws raug nquahu kom xaiv xaiv cov kub kub.
RauHigh-zaus / Kev Kub CeevCov rooj zaum, nws raug nquahu kom xaiv cov plating kub, raws li txheej npib tsib xee plated nrog kub yuav cuam tshuam rau kev sib kis ntawm cov cim nrawm nrawm.
Rau cov nquag tso thiab unplugged qhov chaw xws li kub ntiv tes thiab cov sib txuas, nws raug pom zoo kom xaiv cov plating kub.
Rau qee lub sijhawm uas xav tau hluav taws xob tiv thaiv hluav taws xob, nws pom zoo kom xaiv cov plating kub.
