1. Siv tam sim no:
Vim hais tias sab hauv LED zaub muaj cov yam ntxwv ntawm kev nce ceev tam sim no nrog qhov nce me ntsis hauv qhov hluav taws xob, qhov tam sim no ntau dhau yuav ua rau hlawv ntawm LED teeb lossis txo qis ntawm qhov ci. Thaum siv nws, tus resistor yuav tsum tau muab ntxiv rau hauv series nrog lub teeb LED kom txo tau qhov tam sim no. , Sab hauv LED zaub yuav tsum ua haujlwm raws li cov xwm txheej tam sim no. Feem ntau, nws raug pom zoo tias tam sim no los ntawm LED yog 15-19mA.
2. Kev ntsuas ci ci thiab cov lus qhia khoom:
(1) Thaum kuaj pom thiab siv LEDs, txhua lub LED yuav tsum tau muab nrog tib lub sijhawm tam sim no, uas yog, qhov ntsuas tam sim no tsis tu ncua, txhawm rau xyuas kom pom qhov ci zoo ib yam. Qhov tam sim no yuav tsum zoo dua tsis tshaj 20mA, thiab nws yog qhov zoo tshaj los siv qhov tam sim no ntawm 15-19mA.
(2) Thaum siv cov khoom siv spectrophotometric, thov faib thiab siv lawv nyob rau hauv qhov kev txiav txim ntawm tus lej BIN. Koj tsis tuaj yeem sib xyaw LEDs nrog tus lej BIN sib txawv hauv tib yam khoom kom tsis txhob muaj qhov sib txawv ntawm cov xim, qhov ci, thiab qhov hluav taws xob. Yog tias koj xav sib xyaw BIN tus lej, koj tuaj yeem muab cov lej BIN uas nyob ib sab ua ke, tab sis sim zam lawv.
Peb. Kev tiv thaiv zoo li qub
(1) Tag nrho cov cuab yeej thiab cov cuab yeej uas tiv tauj rau sab hauv LED zaub yuav tsum tau ua kom zoo, tshwj xeeb tshaj yog cov hlau nplaum thiab cov tin furnaces yuav tsum tau zoo hauv av.
(2) Cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes tiv thaiv zoo li qub, khau tiv thaiv zoo li qub thiab cov khaub ncaws tiv thaiv zoo li qub.
(3) Anti-static dab teg yuav tsum tau sim txhua hnub, thiab cov uas tsis dhau yuav tsum tau hloov.
(4) Yog hais tias lub LED raug puas los ntawm hluav taws xob zoo li qub, nws yuav qhia tau qee yam tsis zoo: qhov hluav taws xob tam sim no nce, zoo li qub rau pem hauv ntej voltage txo los yog nce, tsis teeb los yog emits txawv txav nyob rau hauv qis tam sim no ntsuas.
4. Sab hauv LED zaub vuam tej yam kev mob:
(1) soldering hlau welding: qhov kub ntawm cov hlau soldering (qhov siab tshaj 30W) yuav tsum tsis pub tshaj 300 degree; lub sij hawm soldering yuav tsum tsis pub tshaj 3 vib nas this; txoj hauj lwm soldering yuav tsum yog tsawg kawg 3 hli ntawm lub colloid.
(2) Dip soldering: qhov kub siab tshaj ntawm dip soldering yog 260 degree; lub sij hawm dip soldering tsis ntau tshaj 5 vib nas this; lub dip soldering txoj hauj lwm yog tsawg kawg yog 2 mm deb ntawm lub colloid.
5. Lead forming method:
(1) Lub bracket yuav tsum nyob deb 2 hli ntawm lub colloid kom tsis txhob tawg lub colloid los yog ua puas lub sab hauv.
(2) Kev tsim cov stent yuav tsum tau ua nrog cov khoom siv lossis cov kws tshaj lij.
(3) Txoj kev txhawb nqa yuav tsum ua kom tiav ua ntej vuam.
(4) Thaum tsim lub bracket, xyuas kom meej tias cov pins thiab qhov sib txawv yog raws li lub rooj tsav xwm hauv Circuit Court.
6. Sab hauv LED zaub installation txoj kev:
(1) Ua tib zoo saib xyuas cov txheej txheem ntawm cov xov hlau sab nraud ntawm ntau yam khoom siv los tiv thaiv kev teeb tsa polarity tsis raug. Cov cuab yeej yuav tsum tsis txhob nyob ze rau cov cua sov
(2) Nco ntsoov tsis txhob teeb tsa sab hauv LED zaub thaum lub pins deformed.
(3) Thaum txiav txim siab los nruab rau hauv lub qhov, xam qhov loj thiab siab ntev ntawm lub ntsej muag thiab lub qhov nyob deb ntawm lub rooj tsav xwm Circuit Court kom tsis txhob muaj siab dhau ntawm lub bracket.
(4) Thaum txhim kho sab hauv tsev LED cov ntxaij vab tshaus, nws raug nquahu kom siv lub tes tsho qhia rau qhov chaw.
(5) Ua ntej vuam qhov kub thiab txias rov qab mus rau qhov qub, nws yog ib qho tsim nyog kom tsis txhob muaj kev vibration lossis sab nraud quab yuam ntawm sab hauv LED zaub.
7. Kev ntxuav:
Kev saib xyuas tshwj xeeb yuav tsum tau saib xyuas thaum ntxuav cov colloid nrog cov tshuaj, vim qee cov tshuaj tuaj yeem ua rau lub ntsej muag ntawm cov colloid thiab ua rau tsis muaj xim xws li trichlorethylene thiab acetone. Nws tuaj yeem muab so thiab dipped hauv ethanol tsis pub dhau 3 feeb ntawm chav tsev kub.
8. Ua haujlwm thiab cia kub:
(1) LED LAMPS lub teeb-emitting diode Topr{2}} degree ~ 85 degree, Tstg-40 degree ~ 100 degree
(2) LED DISPLAYS zaub Topr-20 degree ~ 70 degree , Tstg -20 degree ~ 85 degree
(3) Sab nraum zoov LED LAMPS pixel tube Topr -20 degree ~ 60 degree , Tstg -20 degree ~ 70 degree
