LED Teeb hlaws yog feem ntau welded

Tso ncaj qha rau LED teeb hlaws hauv cov txheej txheem vuam, thov ua raws li cov cai hauv qab no: 1. Nco ntsoov hnav hnab looj tes anti-static, anti-static dab teg, thiab lwm yam. thaum lub sijhawm tsim khoom tiag. Tsuas yog txhuas. Vim tias cov av noo ntawm tib neeg lub cev ntawm lub rooj zaum ua haujlwm yog 60% -90%, qhov hluav taws xob zoo li qub ntawm tib neeg lub cev yuav ua rau cov khoom siv lead ua ntawm lub teeb ci LED hlaws. Tom qab ib lub sij hawm, LED teeb hlaws yuav qhia tsis ua hauj lwm thiab tuag teeb. 2. Vuam kub yog 260 C, 3 vib nas this. Kub kub thiab ntev dhau lawm yuav hlawv cov chips phem. Txhawm rau tiv thaiv kom zoo dua ntawm LED teeb hlaws, LED teeb hlaws thiab PC boards yuav tsum tau khaws cia ntawm qhov deb ntawm ntau tshaj 2 hli los ua kom cov vuam kub dispel. 3. Qhov kev khiav hauj lwm ib txwm tam sim no ntawm qhov ncaj-inserted LED teeb hlaws yog 20mA, thiab micro fluctuations ntawm qhov voltage yuav ua rau muaj qhov hloov pauv loj ntawm tam sim no. Yog li ntawd, thaum lub sij hawm tsim ntawm lub Circuit Court tsim, sib txawv tam sim no -limiting resistors yuav tsum tau them raws li qhov voltage thiab xa mus rau LED teeb hlaws dai kom ntseeg tau tias LED teeb hlaws dai nyob rau hauv lub zoo tshaj plaws ua hauj lwm lub xeev. Thaum qhov tam sim no loj dhau lawm, LED teeb hlaws hlaws yuav ua rau lub neej luv, qhov tam sim no me dhau, thiab qhov yuav tsum tau ua kom pom kev ci ntsa iab tsis tuaj yeem ua tiav. Peb lub tuam txhab yuav faib cov LED teeb hlaws thaum batch mov, uas yog, LED teeb hlaws tsis muaj nyob rau hauv tib lub pob khoom zoo ib yam, kom ntseeg tau qhov sib xws ntawm cov khoom tiag. Tam sim no, ntau hom LED teeb hlaws vuam txoj kev: 1. Ib leeg hlau welding: lub ntsis ntawm lub ntsis ntawm cov hlau soldering tsis tshaj 300 C, lub vuam lub sij hawm tsis pub tshaj 3 vib nas this, thiab vuam txoj hauj lwm yog tsawg kawg yog 2 hli los ntawm cov colloid. 2. Summit welding: Qhov kub siab tshaj plaws ntawm cov vuam vuam yog 260 ° C, lub sijhawm vuam tsis pub tshaj 5 vib nas this, thiab qhov chaw ntub dej ntub dej yog tsawg kawg 2 hli los ntawm cov colloid. Ncaj nraim ntxig LED teeb hlaws vuam nkhaus pins txoj kev: 1. Yuav tsum yog 2 hli los ntawm collagen kom khoov lub bracket. 2. Kev tsim ntawm lub bracket yuav tsum xyuas kom meej cov pins thiab qhov sib txawv raws li cov kab board. 3. Kev tsim ntawm lub bracket yuav tsum tau ua nrog ib tug fixture los yog los ntawm ib tug kws tshaj lij. 4. Kev tsim ntawm lub bracket yuav tsum ua kom tiav ua ntej vuam.
