Cov khoom siv thov kev txiav txim siab zoo thiab sim ua tau zoo raws li hauv qab no:
(1) Soldering hlau soldering: soldering hlau (txog 30W) hau kub tsis tshaj 300 ° C; pob tshab zaub soldering lub sijhawm tsis tshaj 3 vib nas this; vuam txoj hauj lwm yog tsawg kawg 2 hli los ntawm colloid.
(2) Dip soldering: qhov kub siab tshaj plaws ntawm dip soldering yog 260 ° C; lub sij hawm dip soldering tsis tshaj 5 vib nas this; dip soldering txoj hauj lwm yog tsawg kawg 2 hli los ntawm colloid.
Pin txoj kev tsim qauv
(1) Nws yog qhov yuav tsum tau khoov lub kauj vuam 2 hli deb ntawm lub khoob.
(2) Kev sib sau tes yuav tsum tau ua nrog lub clamp lossis los ntawm ib tug kws tshaj lij.
(3) Kev sib sau tes yuav tsum tau ua tiav ua ntej vuam.
(4) Cov ntawv sib sau ua ke yuav tsum ua kom paub tseeb tias cov pins thiab yov yob sib xyaw nrog pawg tswj hwm.
Ua haujlwm thiab cia kub
(1) LED LAMPS LED Topr-25 ° C ~ 85 ° C, Tstg-40 ° C ~ 100 ° C
(2) LED Tso Tawm Tsa cov zaub Topr-20 ° C ~ 70 ° C, Tstg-20 ° C ~ 85 ° C
(3) QHOV ROOJ-QHOV ROOJ LED TEEBPS cov raj kub Topr-20 ° C ~ 60 ° C, Tstg-20 ° C ~ 70 ° C
LED txoj kev teeb tsa
(1) Ua tib zoo saib xyuas rau kev npaj ntawm cov kab sab nraud ntawm ntau yam khoom siv los tiv thaiv lub polarity los ntawm tsis raug. Cov cuab yeej yuav tsum tsis txhob muab tso dhau rau hauv cov cua sov thiab cov haujlwm kev ua haujlwm yuav tsum tsis pub dhau nws cov kev txwv tshwj xeeb.
(2) Nco ntsoov tsis txhob teeb lub LED nrog tus pin deformed.
(3) Thaum nws tau txiav txim siab los nruab rau hauv lub qhov, laij seb qhov loj me thiab kev zam ntawm lub ntsej muag thiab lub suab ntawm lub rooj tsav xwm kom tsis txhob muaj kev ntxhov siab ntau dhau ntawm lub bracket.
(4) Thaum txhim kho lub LED, cov lus qhia yog tso nrog lub tes tsho coj qhia.
(5) Ua ntej cov cua kub soldering rov qab mus rau qhov qub, LED yuav tsum muaj kev tiv thaiv los ntawm ib qho kev vibration lossis sab nraud quab yuam.
Kev Tu Kom Huv: Kev tu yuav tsum tau ua thaum tu cov gel nrog tshuaj. Cov zaub pob tshab yog puas tsuaj los ntawm qee cov tshuaj lom neeg thiab ua rau fading xws li trichlorethylene lossis acetone. Nws tuaj yeem muab so thiab tsau nrog ethanol tsawg dua 3 feeb ntawm qhov kub.
