Thaum lub rooj tsavxwm PCB lub tshuab nqus tsev ntim thiab xa tawm tom qab kev tshuaj xyuas cov khoom kawg, rau cov laug cam hauv kev txiav txim siab, cov tuam txhab tsim hluav taws xob dav dav yuav ua ntau cov khoom muag lossis npaj ntau cov khoom seem rau cov neeg siv khoom, thiab tom qab ntawd lub tshuab nqus tsev ntim khoom thiab khaws cia tom qab txhua pawg ntawm kev txiav txim. ua tiav.Tos khoom xa tuaj.Yog li vim li cas PCB boards xav tau lub tshuab nqus tsev ntim khoom?Yuav khaws li cas tom qab lub tshuab nqus tsev ntim khoom?Nws lub neej txee ntev npaum li cas?Cov nram qab no Xiaobian ntawm Xintonglian Circuit Court board tuam ntxhab yuav muab cov lus qhia luv luv rau koj.
Txoj kev cia ntawm PCB board thiab nws lub neej txee:
Vim li cas PCB boards xav tau lub tshuab nqus tsev ntim khoom?PCB board manufacturers muab qhov tseem ceeb rau qhov teeb meem no.Vim hais tias ib zaug PCB pawg thawj coj saib tsis raug kaw zoo, qhov chaw immersion kub, tin tsuag thiab cov ntaub qhwv qhov chaw yuav oxidize thiab cuam tshuam rau vuam, uas tsis haum rau kev tsim khoom.
Yog li, yuav ua li cas khaws cov PCB board?Lub rooj tsav xwm hauv Circuit Court tsis txawv ntawm lwm yam khoom, nws tsis tuaj yeem sib cuag nrog huab cua thiab dej.Ua ntej tshaj plaws, lub tshuab nqus tsev ntawm PCB board tsis tuaj yeem raug puas tsuaj.Thaum packing, ib txheej ntawm npuas zaj duab xis yuav tsum tau nyob ib puag ncig ntawm sab ntawm lub thawv.Kev nqus dej ntawm cov npuas zaj duab xis yog qhov zoo dua, uas ua lub luag haujlwm zoo hauv kev ya raws.Ntawm chav kawm, cov hlaws dej-pov thawj kuj tseem yog qhov tseem ceeb.Tom qab ntawd txheeb lawv tawm thiab sau npe rau lawv.Tom qab sib khi, lub thawv yuav tsum tau muab cais tawm ntawm phab ntsa thiab khaws cia rau hauv qhov chaw qhuav thiab qhov cua kom deb ntawm av, thiab yuav tsum tau tiv thaiv los ntawm tshav ntuj.Qhov kub ntawm lub tsev khaws khoom yog qhov zoo tshaj plaws tswj ntawm 23 ± 3 ℃, 55 ± 10% RH.Nyob rau hauv cov xwm txheej zoo li no, PCB boards nrog kev kho mob saum npoo xws li kub kub, electro-kub, tshuaj tsuag tin, thiab nyiaj plating feem ntau tuaj yeem khaws cia rau 6 lub hlis.PCB boards nrog kev kho deg xws li immersion tin thiab OSP feem ntau tuaj yeem khaws cia rau 3 lub hlis.
Rau PCB boards uas tsis tau siv rau lub sijhawm ntev, nws yog qhov zoo tshaj plaws rau cov tuam txhab tsim hluav taws xob los pleev xim ib txheej ntawm peb-pov thawj xim rau lawv.Cov dej num ntawm cov xim peb-pov thawj tuaj yeem tiv thaiv ya raws, plua plav thiab oxidation.Nyob rau hauv txoj kev no, lub neej cia ntawm PCB pawg thawj coj saib yuav nce mus rau 9 lub hlis.
