Taw qhia ntawm SMD LED nyiaj hlau hlau
Silver alloy hlau yog ib yam khoom uas hloov ib txwm kub hlau. Cov khoom tseem ceeb yog ib qho siv lead ua nyiaj, nrog cov ntsiab lus dav dav ntawm 90% -99%. Lwm cov khoom xyaw yog ntau yam kab kawm.
Nyiaj hlau hlau yog ib yam khoom uas tau tshwm sim nyob rau hauv LED kev lag luam los hloov cov tsoos kub hlau nyob rau hauv ob xyoos dhau los. Raws li tus nqi kub tau nce ntxiv hauv ob xyoos dhau los, tus nqi ntawm cov hlau kub siv rau Led ntim kuj tseem nce ntxiv. Nyob rau tib lub sijhawm, tus nqi ntawm cov khoom lag luam Led tau txuas ntxiv poob. Yog li ntawd, pheej yig lwm txoj kev-nyiaj alloy hlau, yuav tawm ntawm lub sijhawm. Raws li kev txheeb cais los ntawm cov koom haum tso cai, txij li lub Rau Hli 2011, kwv yees li 1/3 ntawm Led ntim cov tuam txhab tau hloov pauv los ntawm cov hlau kub mus rau cov nyiaj hlau, thiab qhov kev nkag mus yuav tsum nce mus rau 80% thaum kawg ntawm 2012! Lub ntsiab
Tam sim no, cov tuam txhab muaj feem cuam tshuam hauv Suav teb av loj, Taiwan thiab Nyij Pooj tau tsim cov khoom zoo sib xws, thiab lawv cov thev naus laus zis txawv me ntsis.
Qhov zoo
1. Tus nqi pheej yig. Piv nrog rau cov hlau kub ntawm tib txoj kab uas hla, tus nqi ntawm cov nyiaj hlau tsuas yog kwv yees li ib feem tsib ntawm cov hlau kub;
2. Zoo conductivity;
3. Lub solderability yog zoo dua thaum soldering nrog nyiaj-plated bracket;
4. zoo reflectivity, tsis muaj lub teeb nqus, ci tuaj yeem nce li ntawm 10% piv nrog kev siv cov hlau kub;
5. Zoo cua sov dissipation;
Ua tsis tau
1. Daim ntawv thov ntawm cov khoom siv hluav taws xob niaj hnub siv hluav taws xob tsis paub qab hau lossis yuav tsum tau nruab nrog kev tiv thaiv nitrogen ua ntej nws tuaj yeem siv.
2. Cov kev cai siab tshaj plaws rau cov tuam ntxhab. Yuav kom ua tiav cov txiaj ntsig xav tau, nws feem ntau siv sijhawm ntev los debug cov khoom siv thaum ntxov.
