Kev ceev faj thaum siv 3w siab zog coj
High-power LED teeb hlaws yog tsuas yog siv nyob rau hauv tsev so, tsev so, squares, tuav, chaw ua si, chaw ua si, pej xeem chaw thiab tag nrho cov teeb uas yuav tsum tau lub zog txuag lub teeb.
Kev ceev faj ntau hauv kev siv lub zog loj LED teeb hlaws:
1. Vuam tej yam kev mob
Reflow soldering: Thov preheat nyob rau hauv 2 feeb ntawm 150 ° C, thiab ua 1 soldering nyob rau hauv 5s ntawm 240 ° C tom qab cua sov.
soldering hlau welding: Siv ib tug kub-tswj soldering hlau nrog ib tug siab tshaj plaws kub ntawm 25W, nws lub ntsis kub tsis siab tshaj 320 ° C, thiab ua kom tiav cov soldering ib zaug nyob rau hauv 3 vib nas this. Tsis txhob siv lwm lub zog rau cov khoom thaum soldering. Tsis txhob khoov lub Circuit Court board tom qab soldering tiav.
2. Ntim
Txij li thaum cov dej nqus dej ntawm cov resin ua rau cov dej evaporation thiab nthuav dav thaum lub sij hawm vuam, uas tuaj yeem ua rau lub ntsej muag tev, lub hom phiaj ntawm cov khoom ntim khoom yog los xyuas kom meej tias cov dej noo qis tshaj plaws hauv lub hnab ntim khoom.
High-power LED teeb hlaws dai
Cov khoom yuav tsum tau siv nyob rau hauv ib xyoos txij li hnub ntim. Ua ntej lub hnab ntim tau qhib, nws yuav tsum tau muab cia rau hauv ib puag ncig nrog qhov kub ntawm 5 ~ 30 ° C thiab cov av noo ntawm tus txheeb ze ntawm< 60%.="" tom="" qab="" lub="" hnab="" ntim="" tsis="" tau="" ntim,="" cov="" khoom="" yuav="" tsum="" tau="" welded="" thiab="" siv="" nyob="" rau="" hauv="" 24="" teev,="" txwv="" tsis="" pub="" cov="" khoom="" yuav="" tsum="" tau="" muab="" cia="" rau="" hauv="" ib="" qho="" chaw="" nrog="" ib="" tug="" kub="" ntawm="" 5="" ~="" 30="" °="" c="" thiab="" ib="" tug="" txheeb="" ze="" humidity="">< 30%="" tsis="" muaj="" ntev="" tshaj="" li="" ib="" lub="" lim="" tiam;="" yog="" tias="" muaj="" cov="" khoom="" siv="" tsis="" siv,="" thov="" muab="" lawv="" rov="">
Lub hnab ntim dej tsis zoo yog kaw thiab khaws cia. Yog tias cov khoom siv ntau tshaj qhov kev cia siab saum toj no lossis ntub dej, nws yuav tsum tau ci ntawm 60 ± 5 ℃ rau 12 teev. Lub electrode nto ntawm cov khoom yog kub-plated, uas yooj yim rau corroded los yog discolored, uas ua rau vuam nyuaj. Nws raug nquahu kom siv nws sai li sai tau. Saib xyuas kom tsis txhob muaj kev hloov pauv sai hauv qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej.
3. Kev tiv thaiv hluav taws xob zoo li qub
High-brightness xiav, ntsuab thiab dawb cov khoom yog rhiab heev rau hluav taws xob zoo li qub. Hauv kev siv, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau cov hluav taws xob hluav taws xob uas yuav ua rau cov khoom puas lossis puas. Thov siv lub ncoo conductive rau hauv av lub workbench uas yog nyob rau hauv kev sib cuag nrog cov khoom los ntawm kev tiv thaiv; qhov kawg ntawm cov hlau soldering yuav tsum tau grounded; pom zoo siv ionizer.
