Cov txheej txheem teeb tsa LED thiab cov tseev kom muaj yog dab tsi?
Raws li qhov xwm txheej ib txwm muaj, txheej txheem teeb tsa LED thiab cov tseev kom muaj yog raws li hauv qab no
1. Soldering hlau vuam xav tau: qhov ntsuas kub ntawm cov hlau txuas (siab tshaj 30W) yuav tsum tsis pub tshaj 300 ℃; lub sij hawm soldering yuav tsum tsis pub tshaj 3 vib nas this; txoj hauj lwm soldering yuav tsum yog yam tsawg 2 hli ntawm cov colloid.
Dip soldering: qhov kub siab tshaj plaws ntawm dip soldering yog 260 ℃; lub sij hawm soldering poob tsis ntau tshaj 5 vib nas this; txoj hauj lwm dip soldering yog yam tsawg 2 hli deb ntawm colloid.
LED tus pin shaping txoj kev:
Kev hloov pauv ntawm LED teeb yuav tsum tau ua nrog tus jig lossis los ntawm tus kws tshaj lij.
Txoj kev txhawb nqa yuav tsum ua kom tiav ua ntej vuam.
Lub LED yuav tsum yog 2 hli deb ntawm cov colloid txhawm rau khoov lub bracket.
Lub bracket yuav tsum tau tsim los xyuas kom meej tias tus pin thiab qhov sib nrug zoo ib yam nrog lub rooj tsav xwm hauv Circuit Court.
2. LED txoj kev teeb tsa
Them sai sai rau kev teeb tsa cov xov hlau sab nraud ntawm ntau yam khoom siv txhawm rau tiv thaiv kev teeb tsa polarity tsis raug. Cov cuab yeej yuav tsum tsis txhob nyob ze rau qhov cua sov, thiab cov haujlwm ua haujlwm yuav tsum tsis txhob tshaj qhov nws tau txwv.
Nco ntsoov tsis txhob teeb lub LED thaum cov pins deformed.
Thaum txhim kho LED, nws raug nquahu kom siv lub tes tsho qhia rau txoj haujlwm.
Ua ntej qhov ntsuas kub rov qab mus rau qhov qub, LED yuav tsum tau tiv thaiv los ntawm kev co lossis lwm lub zog
Kev saib xyuas tshwj xeeb yuav tsum tau ua thaum ntxuav cov colloid nrog tshuaj, vim tias qee yam tshuaj tuaj yeem ua rau cov colloid puas thiab ua rau muaj xim tsis zoo, xws li trichlorethylene thiab acetone. Nws tuaj yeem so thiab dipped hauv ethanol tsis pub ntev tshaj 3 feeb ntawm chav sov.
Thaum txiav txim siab teeb tsa hauv lub qhov, suav qhov loj thiab ua siab ntev ntawm lub ntsej muag thiab qhov nyob deb ntawm lub rooj tsav xwm hauv Circuit kom tsis txhob muaj lub siab ntau dhau ntawm tus tuav.
3. Ua haujlwm thiab cia kub ntawm ntau yam coj:
LED teeb emitting diode Topr-25 ℃ ~ 85 ℃ 、 Tstg-40 ℃ ~ 100 ℃
LED zaub Topr-20 ℃ ~ 70 ℃ 、 Tstg-20 ℃ ~ 85 ℃
LED pixel raj Topr-20 ℃ ~ 60 ℃ 、 Tstg-20 ℃ ~ 70 ℃
