1. VUAM HOM
Feem ntau, vuam vuam tuaj yeem faib ua peb hom: hluav taws xob soldering hlau vuam, cua sov platform vuam, cua sov platform vuam, cua sov platform vuam thiab reflow soldering vuam vuam:
A: Cov qauv feem ntau yog cov hluav taws xob sib dhos, xws li kev hloov thiab kho cov hluav taws xob sib xyaw. Tam sim no, LED tuam ntxhab, txhawm rau txuag lawv cov nqi ntau lawm, feem ntau siv cuav thiab siv cov hluav taws xob cuav soldering irons, ua rau muaj kev sib tiv tauj tsis zoo thiab qee zaum toast. Thaum lub sij hawm vuam sib tw, qhov no sib npaug rau kev tsim cov kab ke ntawm cov kab mob hlau - thiab lub ntiaj teb coj los siv rau cov hlaws teeb LED, tam sim ntawd hlawv lawv tawm.
B: Lub teeb uas tuag los ntawm vuam cua sov tau dhau los ua cov khoom lag luam me me kom tau raws li cov kev xav tau me me hauv kev xav tau ntawm cov khoom lag luam me txuas ntxiv. Vim yog qhov zoo ntawm cov khoom siv tsawg dua, cov kev ua haujlwm yooj yim thiab cov teeb meem cua sov tau ua cov kev siv cua sov (thiab kev tswj hwm ntawm vuam ceev, muaj qhov teeb meem ntawm kev ua kom muaj teeb meem ntawm kev tuag. Ib qho ntxiv, muaj qhov av ntawm cov cua sov cov khoom siv.
C: Wflow soldering feem ntau yog qhov kev ntseeg siab tshaj plaws, uas haum rau huab hwm coj ntau lawm thiab ua. Yog tias txoj kev ua haujlwm tsis raug, nws yuav ua rau muaj kev tsis txaus ntseeg ntau, xws li tsis tsim nyog kub, tsis zoo tshuab av, thiab lwm yam.
2. Kho kom muaj teeb meem tuag
Qhov no feem ntau tshwm sim. Thaum peb qhib lub pob, peb tsis them sai sai-pov thawj ntsuas. Feem ntau ntawm cov teeb hlaws dai rau ntawm kev ua lag luam tam sim no tau muab ntim nrog Silica Gel. Cov ntaub ntawv no yuav nqus dej. Thaum lub teeb tsom teeb cuam tshuam nrog noo noo, silica gel yuav thermal nthuav tawm tom qab kub vuam. Cov xaim kub kub, nti thiab cov bracket yuav deformed, ua rau lub chaw tso tawm nyob rau hauv ib puag ncig kub, thiab qhov chaw cia khoom, nrog cov av noo ntawm tsawg dua 85%; Nws raug nquahu kom siv cov LED nyob rau hauv nws cov khoom muaj mob qub hauv 3 lub hlis kom tsis txhob xeb ntawm lub bracket; Tom qab lub hnab ntim nqa tau qhib, nws yuav tsum tau siv kom sai li sai tau. Lub sijhawm no, qhov chaw cia kub yog 5 ℃ -30 ℃, thiab cov txheeb ze cov av noo qis dua 60%.
3. Tshuaj Tu
Tsis txhob siv cov kua dej tsis paub los ntxuav cov coj, vim tias nws yuav ua rau kev puas tsuaj ntawm LED colloid thiab txawm tias ua rau tawg colloid. Yog tias tsim nyog, thov huv si nrog cov cawv cawv hauv chav sov thiab cua ib puag ncig, nyiam dua li ntawm ib feeb ntawm kev ua tiav.
4. Deformation ua rau tuag lub teeb
Vim yog kev deformation ntawm qee cov vaj huam sib luag, cov neeg ua haujlwm yuav yauv phais yas. Raws li cov panels deform, lub teeb hlaws rau lawv kuj deformorm ua ke, rhuav cov xaim kub thiab ua rau lub teeb tsis pom kev. Nws raug nquahu kom ua cov yas phais ua ntej ntau lawm rau hom vaj huam sib luag no. Ntev los ua ke thiab tuav thaum lub sij hawm tsim khoom kuj tseem ua rau deformation thiab tawg ntawm cov xov hlau kub. Tsis tas li, nws tshwm sim los ntawm stacking. Txhawm rau pab txhawb nqa cov txheej txheem ntau lawm, lub teeb vaj huam sib luag yog cia li muab teev cia. Vim tias lub ntiajteb txawj nqus, txheej qis dua ntawm teeb hlaws hlaws yuav deformed thiab ua puas cov xov kub kub.
5. Lub tshav kub dissipation qauv, muab fais fab, thiab teeb pawg tswj hwm tsis sib xws
Vim tias tsis raugKev pab fais fabkev tsim qauv lossis xaiv, lub zog hluav taws xob tau tshaj qhov txwv siab tshaj plaws uas tau tiv thaiv tau (tshaj tam sim no, kev cuam tshuam tam sim no); Cov qauv siv hluav taws xob sov sov uas muaj teeb meem ntawm teeb pom kev zoo tuaj yeem ua rau lub teeb tuag thiab lub teeb ua ntej lub teeb lwj.
6. Lub Hoobkas Grounding
Nws yog ib qho tsim nyog los tshawb xyuas seb puas muaj cov xaim xaim hluav taws xob tag nrho ntawm lub Hoobkas yog qhov zoo
7. Lub Hluav Taws Xob Hluav Taws Xob Zoo Li Qub
Hluav taws xob zoo li cas tuaj yeem ua rau LED ua haujlwm tsis ua haujlwm, thiab nws raug nquahu kom tiv thaiv ESD los ntawm kev ua kom cov LED.
A: Thaum lub sijhawm kuaj thiab sib dhos, cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes zoo li qub thiab kev tawm tsam cov hnab looj tes qub.
B. Vuam thiab kuaj cov cuab yeej siv, cov ntxhuav ua haujlwm, cov khoom siv khaws cia, thiab lwm yam.
C. Siv lub If blower kom tshem tawm cov hluav taws xob zoo li qub tsim los ntawm kev sib txhuam thaum lub rooj khaws khoom coj thiab rooj sib txoos.
D. Cov thawv khoom rau teeb tsa LED Adopts cov khoom siv los tiv thaiv lub thawv, thiab lub hnab ntim tau ad electrostatic lub hnab.
E. Tsis txhob muaj qhov hnoos qeev thiab kov lub LED casually.
Qhov txawv txav xwm txheej uas LED kev puas tsuaj los ntawm ESD suav nrog:
A. Rov qab toast tuaj yeem ua rau muaj kev pom zoo hauv cov mob me, thiab lub teeb yuav tsis tig rau hauv cov neeg mob hnyav.
B. Cov qauv rau pem hauv ntej txo qis. LED tsis tuaj yeem tawm teeb thaum tsav los ntawm qis tam sim no.
C. Kev siv vuam tsis zoo ua rau lub teeb kom tsis txhob pom.
