Nov yog qee cov lus qhia kws paub txog yuav ua li cas txiav txim siab no:
1. Kev them taus
Nyob rau hauv cov nqe lus ntawm kev sib piv ntawm HASL lead-dawb thiab HASL coj, peb yuav hais tias tus qub yog kim dua.Yog li ntawd, yog tias koj nyob rau hauv ib tug nruj pob nyiaj siv los yog xav kom txuag tau nyiaj, mus rau ib tug HASL lead ua tiav yog ib txoj hauv kev zoo dua los txuag nyiaj.
2. RoHS ua raws
Muab cov teeb meem kev noj qab haus huv thiab lub cev muaj teeb meem cuam tshuam nrog kev siv cov khoom siv hluav taws xob, qhov tob ntawm qhov cuam tshuam uas hla kev kuaj xyuas lub rooj tsav xwm coj mus rau cov neeg siv khoom tsim nyog.
Kev ua raws RoHS tam sim no yog tus qauv rau feem ntau cov haujlwm PCB thiab cov neeg siv khoom feem ntau tau saib xyuas cov lus qhia no.Vim li no, xaiv HASL cov khoom tsis muaj hlau lead yog qhov kev xaiv zoo dua yog tias koj xav ua RoHS-raws li Circuit Court boards.
Qhov no yog vim muaj ntau dua concentration ntawm tin thiab ib qho me me ntawm tooj liab.Raws li tsis muaj txhuas siv ntawm no, koj tuaj yeem paub tseeb tias cov teeb meem kev noj qab haus huv tsis zoo uas nws nce tsis muaj dab tsi txhawj txog.
Ib qho tseem ceeb rau kev ua tiav, txawm li cas los xij, yog tias tsis muaj cov khoom zoo hauv PCB.Cov khoom xws li BGAs thiab SMDs tsis zoo rau qhov kev hwm no.
3. Durability yuav tsum
Ntxiv rau kev tiv thaiv tooj liab thiab lwm yam tseem ceeb, kev ua haujlwm ntawm kev kho saum npoo yuav tsum txuas ntxiv mus rau kev txhim kho lub zog ntawm PCB.Qhov ntau ruaj ib lub rooj tsavxwm dhau los ntawm nws daim ntawv thov, nws yuav kav ntev dua.
4. Daim ntawv thov thiab kev ua haujlwm
Daim ntawv thov, piv txwv li qhov twg lub rooj tsavxwm coated nrog ib qho ntawm cov kev ua tiav no yuav raug siv, yog qhov tseem ceeb rau kev txiav txim siab.Vim li no, daim ntawv thov lossis cov ntaub ntawv siv yuav tsum raug coj mus rau hauv tus account los pab xaiv qhov tsim nyog.
5. Xav txog ib puag ncig
Tsis txhob nkim ib puag ncig nrog daim ntawv thov lossis siv rooj plaub.Los ntawm ib puag ncig ntawm no peb txhais tau tias hom lossis theem ntawm qhov raug pom tias cov ntawv luam tawm Circuit Board (PCB) zoo li yuav raug cuam tshuam thaum nws tau coated nrog lub npoo tiav.
Ib puag ncig feem ntau yog hais txog qhov kub thiab txias - txawm tias hnyav los yog mob me.Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, siv HASL cov khoom tsis muaj hmoov txhuas raws li nws tau ua raws RoHS, uas ua rau nws tus phooj ywg zoo rau ob tus neeg siv thiab ib puag ncig ib puag ncig.
6. Xaiv ENIG tshaj HASL kev kho qhov chaw tsis muaj hlau lead
Peb (3) cov kev xaiv tseem ceeb ua ntej koj rau PCB nto tiav yog HASL, HASL Lead Free thiab ENIG.Txawm hais tias peb cov ntaub ntawv no muaj cov khoom sib txawv, ib qho tuaj yeem yog qhov kev xaiv zoo dua li lwm tus.
Ua ntej, koj yuav tsum xaiv HASL tsis pub dhau HASL vim nws yog RoHS raws, uas txhais tau hais tias nws tuaj yeem siv rau ntau yam ntawm PCB tiav.Qhov tseeb tias nws muaj cov khoom zoo heev yog lwm qhov muag.
Ntawm qhov tod tes, yog tias koj xav txuag nyiaj thiab ua haujlwm ntawm PCBs uas xav tau qhov kub thiab txias, HASL yog qhov kev xaiv zoo.
Yog tias koj tsis paub meej tias ob qho tib si HASL tsis muaj txhuas thiab HASL yuav tau ua haujlwm li cas, ces xaiv electroless nickel immersion kub (ENIG) yog qhov kev xaiv zoo tshaj.Tsis tas li ntawd, ENIG yuav luag zoo ib yam li HASL tsis muaj txhuas, xws li ua raws RoHS.
Zhejiang NeoDen Technology Co., Ltd. tau raug tsim thiab xa tawm ntau yam me me thiab qhov chaw tshuab txij li xyoo 2010. Ua kom zoo dua ntawm peb tus kheej muaj kev paub txog R&D, kev cob qhia zoo, NeoDen yeej lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
Peb ntseeg hais tias cov neeg zoo thiab cov neeg koom tes ua rau NeoDen yog ib lub tuam txhab zoo thiab tias peb txoj kev cog lus rau Innovation, Diversity thiab Sustainability kom ntseeg tau tias SMT automation yog siv tau rau txhua tus neeg nyiam nyiam nyob txhua qhov chaw.
