Kev npaj ntawm Cheebtsam
Kev npaj ntawm cov khoom tsim nyog yog thawj kauj ruam hauv kev tsim khoomLED vaj huam sib luag. LED chips, uas feem ntau yog tsim los ntawm cov khoom siv semiconductor xws li gallium arsenide lossis gallium nitride, yog qhov tseem ceeb ntawm LED panels. Siv cov txheej txheem nyuaj uas suav nrog kev loj hlob siv lead ua wafers, tso cov txheej txheem ntawm ntau yam ntaub ntawv siv txoj hauv kev xws li tshuaj vapor deposition (CVD), thiab tom qab ntawd tsim cov txheej txheem los tsim cov hluav taws xob thiab kho qhov muag ntawm LED, cov chips no tau tsim hauv cov khoom siv hluav taws xob semiconductor. Ntxiv nrog rau cov chips LED, Circuit Court boards yog qhov tseem ceeb. Cov txheej txheem ntau-cov kauj ruam yog siv los ua cov ntawv luam tawm, lossis PCBs. Lub tooj liab-clad laminate yog ua ntej. Cov kev teeb tsa hauv Circuit Court yog tom qab ntawd xa mus rau qhov chaw tooj liab siv cov tswv yim zoo li photolithography. Ua tib zoo npaj txoj hauv kev hluav taws xob tau tso rau hauv qhov chaw tom qab tsis xav tau tooj liab raug tshem tawm los ntawm etching. Txhawm rau tiv thaiv lub voj voog thiab tsis txhob cuam tshuam luv luv, lub npog ntsej muag yog siv tom qab lub qhov drilled rau cov khoom txuas. cov
Thaum tshav kub kub dab dej, uas dissipate lub tshav kub uas tsim thaum lub sij hawm ua hauj lwm, thiab diffusers, uas pab nyob rau hauv uniformly dispersing lub teeb emitted los ntawm lub LEDs, kuj tsim. Thaum tshav kub kub dab dej tuaj yeem tsim los ntawm cov hlau zoo li txhuas siv tuag-casting lossis machining, thaum diffusers feem ntau yog tsim los ntawm cov yas siv kev txhaj tshuaj molding lossis extrusion cov txheej txheem.
LED Chip Installation
LED chips yog affixed rau lub rooj tsavxwm Circuit Court tom qab cov khoom tau npaj. Cov txheej txheem no muaj tseeb heev yog hu ua nto-mount technology (SMT) lossis nti- ntawm-a- pawg thawj coj saib (COB). Siv cov stencil, solder paste yog pib siv rau PCB cov ntaub ntawv tshwj xeeb hauv SMT. Kev xaiv-thiab- qhov chaw tshuab yog siv los maj mam ntxig cov chips LED mus rau lub solder-coated pads. Cov cuab yeej no khaws cov chips ib tus neeg los ntawm ib lub tais thiab muab tso rau ntawm lub rooj tsavxwm siv lub tshuab nqus tsev{11}}suction nozzles. Tom qab muab tso rau, lub qhov cub reflow yog siv los ua cov PCB uas muaj cov chips LED ntsia. Cov tshuaj nplaum nplaum yog yaj hauv qhov cub los ntawm kev ua tib zoo tswj qhov kub thiab txias, uas ua rau cov khoom siv hluav taws xob thiab hluav taws xob sib txuas ntawm LED chips thiab lub rooj tsav xwm hauv Circuit Court. Txhawm rau lav qhov raug soldering tsis muaj overheating lossis ua mob rau cov chips LED tsis yooj yim, cov txheej txheem no yuav tsum muaj qhov kub thiab txias profile.
Hluav taws xob thiab Hluav taws xob sib dhos
Kev sib txuas hluav taws xob ntawm LED chips thiab lwm yam khoom siv hluav taws xob yog ua tom qab lub nti mounting. Cov kab hluav taws xob yuav tsum tau ua yog siv cov xov hlau lossis cov kab hluav taws xob. Txhawm rau kom lub zog ntawm LEDs thiab tswj lawv txoj haujlwm, suav nrog kev hloov xim lossis ci ntsa iab hauv cov xim - hloovLED vaj huam sib luag, tej yam kev sib txuas yog qhov tseem ceeb. Lwm yam khoom siv hluav taws xob, xws li cov tswj hwm thiab cov tsav tsheb, qee zaus kuj tau nruab rau ntawm lub rooj tsavxwm. Lub luag haujlwm ntawm kev hloov hluav taws xob nkag mus rau hauv qhov tsim nyog voltage thiab tam sim no xav tau los ntawm LED chips poob rau LED tsav tsheb. Conversely, controllers saib xyuas kev khiav hauj lwm xws li xim sib tov, dimming, thiab sequencing. LED vaj huam sib luag kev tsim hluav taws xob ua tiav los ntawm kev ua tib zoo soldering lossis txuas cov khoom no rau PCB.
Kev tiv thaiv thiab Encapsulation
LED vaj huam sib luag mus los ntawm cov txheej txheem encapsulating los tiv thaiv cov khoom siv hluav taws xob thiab LED chips los ntawm ib puag ncig cov ntsiab lus xws li ya raws, plua plav, thiab kev puas tsuaj. LED chips thiab Circuit Court board yog them nrog ib txheej encapsulant, uas feem ntau yog ib tug ntshiab los yog semi-pob tshab tshuaj xws li silicone los yog epoxy resin. Los ntawm kev ua kom lub teeb kis tau zoo thiab txo lub teeb poob, qhov encapsulant no tsis tsuas yog muaj kev tiv thaiv lub cev tab sis kuj tseem txhawb nqa LED vaj huam sib luag kev txhim kho kho qhov muag. Muaj ntau ntau txoj hauv kev rau encapsulating, suav nrog molding lossis tsuas yog sprinkling lub encapsulant ncaj qha rau ntawm lub rooj tsavxwm. Tom qab daim ntawv thov, lub encapsulant tau kho rau lub sijhawm teem tseg thiab ntawm qhov ntsuas kub uas tau txiav txim ua ntej kom khov thiab muab kev tiv thaiv ntev ntev -.
Muab cov khoom sib xyaw ntxiv
Tom qab lub encapsulation ntawm cov hluav taws xob thiab core LED Cheebtsam, lub vaj huam sib luag yog sib sau ua ke nrog cov khoom ntxiv xws li cov dab dej kub thiab diffusers. Txhawm rau kom tawg lub teeb sib npaug thiab tshem tawm cov hotspots, lub diffuser tau ua tib zoo muab tso rau hauv cheeb tsam LED. Feem ntau, mechanical fasteners lossis adhesives yog siv los txuas rau nws. Cov khoom siv hluav taws xob sib txuas, xws li thermal paste lossis cov ntaub qhwv, yog siv los ua kom cov cua sov-hloov efficiency ntawm cov cua sov- tsim cov khoom thiab cov dab dej kub. Lub dab dej kub yog tom qab ntawd ntsia, feem ntau nyob ze nrog cov chips LED lossis lub rooj tsav xwm hluav taws xob kom hloov cov cua sov kom zoo. Quality Assurance and Testing LubLED vaj huam sib luagmus los ntawm kev tswj xyuas kev ua tau zoo thiab cov txheej txheem kuaj ua ntej xa mus rau lub khw. Txhawm rau kom paub tseeb tias cov vaj huam sib luag LED ua haujlwm tau raug, kev ntsuas hluav taws xob tau ua los ntsuas qhov hloov pauv xws li voltage, tam sim no, thiab kev siv hluav taws xob. Lub panels 'xim rendering Performance index (CRI), xim kub, thiab lub teeb tso zis yog txhua yam ntsuas optically. Cov kev ntsuam xyuas no pab kom paub tseeb tias cov vaj huam sib luag LED xa cov teeb pom kev zoo sib xws thiab ua tiav cov kev xav tau ua haujlwm tsim nyog. Txhawm rau soj ntsuam cov vaj huam sib luag 'cov kav ntev, kev sim tshuab thiab ib puag ncig kuj tau ua. Txhawm rau ua kom cov vaj huam sib luag LED tuaj yeem zam tau ntau yam ntawm kev ua haujlwm, qhov no suav nrog kev sim rau kev poob siab, kev vibration, thiab qhov kub thiab txias - av noo. LED vaj huam sib luag tsuas yog suav tias tsim nyog thiab npaj rau kev faib tawm yog tias lawv ua tiav tag nrho cov kev xeem no. Txhawm rau ua kom tiav, kev tsim cov LED vaj huam sib luag yog ntau-theem, kev sib tw, thiab cov txheej txheem thev naus laus zis uas suav nrog txhua yam los ntawm kev npaj cov khoom mus rau kev tswj kom zoo. Txhawm rau tsim cov vaj huam sib luag LED uas siab{10}} zoo, ntev- kav ntev, thiab lub zog- ua haujlwm tau zoo, txhua txoj kev yuav tsum tau ua kom tiav thiab ua tib zoo saib kom meej. Cov txheej txheem tsim khoom rau LED vaj huam sib luag tau hloov nrog kev siv thev naus laus zis, uas yuav ua rau muaj txiaj ntsig ntau dua thiab cov khoom siv tau zoo hauv txoj kev.
