2.Cov khoom siv
Cov ntaub ntawv yog qhov tseem ceeb heev thaum nws tuaj mus rau lub rooj sibtham tso rau hauv Circuit Court lossis lub rooj sibfwv hauv cov ntawv luam tawm. PCBs nrog cov ntaub ntawv tsis muaj peev xwm ua rau lub sijhawm tseem ceeb, tawg, ntes hluav taws, ua rau muaj kev phom sij lossis cuam tshuam txog kev lag luam. Uniwell tsuas yog siv cov ntaub ntawv zoo tshaj plaws rau txhua lub PCB kom txaus kom paub tseeb tias koj tau txais cov txiaj ntsim zoo tshaj plaws nrog rau cov teeb liab kis, kev thermal conductivity thiab kev nyab xeeb.
3. Hom tshuaj tiav hom
Cov nplais ntawm cov ntawv cog lus Circuit Court (PCB) yog ua los ntawm tooj los xyuas kom cov hluav taws xob ntws khiav zoo. Cov hlau no yuav tsum muaj kev tiv thaiv kom zoo los ntawm cov qauv kom tsis txhob oxidation thiab lwm yam kev txhav. Ib hom kev sib tw tiav ntau theem ntawm kev tiv thaiv tawm tsam. Lawv kuj pab nyob rau hauv qee yam kev siv, xws li nrog cov laug tshuab. Muaj ntau lub rooj sib tham ntawm Circuit Board yog tsim los ntawm cov kev xaiv uas pheej yig thiab yooj yim-rau-siv rau kim los yog nyuaj-rau-xeem tiav nyob rau hauv cov kev siv tshaj plaws.
Immersion kub (ENIG)
Electroless Nickel Immersion Kub yog ib feem ntawm cov txheej txheem nrov tshaj plaws uas siv dav rau kev sib cog lus tiav rau hnub no. Tsim los ntawm ob lub txheej ntawm txheej, ENIG qhov chaw 2-4 μ "Au dhau 120-200 μ" Ni. Cov kub npog cov xaim hluav taws xob ntawm lub xauv npoo thiab cov xees npuaj ntawm lub npoo hlau thaiv thiab tso cai rau circuits kom zoo zoo rau nws qhov chaw.
Kev Zoo: cov voj voog saum npoo av, Cov Khoom Taw Qhia Dawb thiab RoHS Ua Raws Li, Cov Txwv Txuas Ntev, Tight tolerances tuaj yeem tuav rau plated qhov.
Disadvantages: kim, teeb liab tsis zoo rau cov teebmeem kev paub teeb liab, dub ncoo.
Immersion nyiaj
Immersion Tin (IAg) siv ncaj nraim rau lub hauv paus hlau ntawm PCB ntawm kev xa tawm tshuaj. Nws yog ib qho kev xaiv pheej yig dua ENIG, thiab nws kuj yog RoHS-raws txoj cai. Ib qhov hnyav rau cov nyiaj siv hauv Immersion Silver yog 4-12u ". Vim txoj kev ua tau tooj thiab nyiaj sib cuam tshuam, lawv thiaj li sib kis mus rau ib leeg.
Kev Zoo: cov voj voog saum npoo av, Cov Twj Txheej thiab RoHS raws li, tighter tolerances tuaj yeem tuav rau plated qhov, tsis tshua poob rau Cov Ntawv Sau Tias Tseem Ceeb Hauv Daim Ntawv Tshaj Tawm.
Cov kev tsis zoo: tuav tswj PCB tuaj yeem ua teebmeem daws teeb meem, nws yog tus nqi zoo tshaj ENIG tab sis tsawg dua tus nqi zoo tshaj ntawm ISn, thiab qhov xaus yuav ua tau thiab oxidize.
Kev sib tw tin
Kev Tiv Thaiv (ISn) siv ncaj nraim mus rau lub hauv paus hlau ntawm PCB ntawm kev xa tawm tshuaj. Nws yog ib qho nqi pheej yig dua ENIG thiab Immersion Silver, thiab nws kuj yog RoHS-raws txoj cai. Ib tug tuab tuab raug rau Tuab Qhib Tin yog 20-50u ". Vim txoj kev tin thiab copper sib cuam tshuam, lawv thiaj li diffuse rau ib leeg.
Zoo: qhov chaw tiaj tiaj rau lub lauj kaub rau, Kev Taug Ceg-dawb thiab RoHS raws txoj cai, tighter tolerances tuaj yeem tuav rau plated qhov thiab yog ib qho kev xaiv zoo rau kev siv xovxwm zoo haum.
Cov kev tsis zoo: tuav tus PCB tuaj yeem tsim kev puas tsuaj thiab kev daws teeb meem, tin whiskers, luv dua lub neej dua ENIG.
HASL
HASL yog ib txoj hauv kev them taus uas yog siv cov tin / coj los tsim kom muaj kev tiv thaiv nyias ntawm PCB. Cov huab cua kub hnyiab yog siv los ntxuav cov hlau lead ntau los yog taum ntawm lub rooj tsavxwm. Ua ntej qhov kev lag luam, HASL qhov chaw muaj kev puas tsuaj vim muaj tej teeb meem ntawm RoHS ua rau.
Qhov zoo tshaj plaws: qis dua, txee lub neej ntev, thiab HASL yog cov ua haujlwm tshiab.
Disadvantages: tsis sib npaug ntawm sab nraud rau cov koob thaij, Cov Ntaus (Tsis Raug Raws Cai RoHS), tsis tuaj yeem tuav lub nrawm rau ntawm cov qhov hauv plated.
Pb-Dawb HASL
Cov tsis muaj teebmeem PCB cov hom phiaj yog tau txais vim muaj kev txhawj xeeb tom qab siv cov hlau lead hauv kev tsim. Pb-Dawb HAL tiav tau siv cov tooj liab los yog tooj sib khi nrog cov xees npua los tsim kev tiv thaiv kev tiv thaiv. Pb-Dawb HASL muaj qhov zoo thiab qhov tsis zoo ib yam li HASL tshwj tsis yog Pb-DAWB HASL yog RoHS raws thiab Lead-Free.
OSP
Ib qho PCB qhov sib tw tiav sib piv raws li ntsuab thov tsis muaj lus nug. Lub Organic Solderability Preservative (OSP) tsis qhia cov co toxins rau hauv tus txheej txheem. Es tsis txhob, ib qho chaw organic yog siv cov khoom sib txuas nrog tooj liab, tsim kom muaj cov kab hauv nruab cev uas tiv thaiv kev tiv thaiv corrosion.
Zoo: thaj chaw tiaj nyom rau kev siv phom, RoHS Raws Li Kev Cai thiab Taug Txhuas Dawb, Cov Nqi Siv Nyiaj. Cov tsis zoo yog; luv txee lub neej, tuav lub PCB tuaj yeem ua teeb meem daws teeb meem, thickness tsis yog ntsuas tau.
Disadvantages: luv txee lub neej, tuav lub PCB tuaj yeem ua teeb meem daws teeb meem, thickness tsis yog ntsuas tau.
Tawv kub
Ntawm qhov kim PCB deg lub hom phiaj, cov ntawv teev cov tawv kub tsis tshua muaj neeg pom thiab txaus siab rau lub neej ntev txee. Lawv feem ntau reserved rau cov khoom uas xav tias yuav tau txais kev siv ntau heev, siv nrog cov tawv nqaij ib txwm siv los ntawm 30 cov kub kub tshaj 100 cov txiv roj nickel rau 50 μt kub dhau 100 cov txiv roj nickel. Nws tsis nquag siv rau cov ntsiab lus tseem ceeb, vim tsis muaj qhov nyuaj. Taws kub yog feem ntau siv rau kev sib txuas ntawm ntug kev, roj teeb, thiab ib co kev ntsuas ntawv.
Qhov Zoo Tshaj Tawm rau Nyuaj Khoom Taw: cov hlau nplaum, Cov Taug Txhuas Dawb thiab RoHS Kev Tsis Txaus Siab, thiab lub neej txuag ntev.
Disadvantages: tsis tshua muaj nqi tshaj rau lwm cov kev sib tw, kev caij npav yuav tsum tau ua, thiab yuav tsum ua haujlwm ntxiv.
Uniwell muaj ntau hom kev sib tw tiav xws li ENEPIG, Wire Bondable Mos Gold, thiab lwm tus, nyob ntawm daim ntawv thov.
Xyuas kom koj tus PCBs ua raws li tau npaj tseg los ntawm kev txiav txim siab txhua kauj ruam hauv kev tsim khoom tsim rau koj cov kev xav tau. Ua li ntawd, koj yuav tsum tau txais kev pab ntawm ib lub tuam txhab muaj kev paub nrog cov neeg ua haujlwm zoo thiab muaj kev xaiv ntau yam.
