LED module ntau lawm pib nrog kev ua ntawm PCBs thiab cov khoom siv hluav taws xob. PCBs yog fabricated raws li specifications hais txog pixel suab, qhov ntev, thiab Circuit Court tsim; Tom qab ntawd, nto-mount thev naus laus zis (SMT) cov cuab yeej siv los txuas cov khoom siv-xws li LED hlaws, tsav chips, resistors, thiab capacitors- mus rau lub rooj tsavxwm ntawm lawv qhov chaw xaiv. Tom qab muab cov khoom pov tseg, cov txheej txheem rov ua dua yog ua haujlwm los tsim kev sib txuas ruaj ntseg ntawm cov khoom thiab cov PCB pads. Cheebtsam uas yuav tsum tau los ntawm - qhov mounting undergo cais insertion thiab soldering kauj ruam. Thaum soldering ua tiav, lub rooj tsav xwm hauv Circuit Court tau kuaj pom los txheeb xyuas cov teeb meem xws li cov pob qij txha uas ploj lawm, cov pob qij txha txias txias, luv luv Circuit Court, los yog qhov chaw tsis raug, kom ntseeg tau tias lub module yog npaj rau lub zog tom ntej - ntawm kev sim.
Tom ntej no, LED module tau txais kev sib dhos thiab kev tiv thaiv kev ua haujlwm. Cov txheej txheem PCB raug teeb tsa rau hauv lub tsev yas lossis cov qauv tsim, ua raws li cov khoom siv xws li lub ntsej muag lub ntsej muag, cov khoom sib txuas, thiab cov hlua khi. Rau sab nraum zoov LED modules, kev tiv thaiv ntxiv -xws li cov roj hmab tsis muaj dej thiab cov sealant- yog siv los siv cov txheej txheem sealing zoo los txhim kho dej thiab hmoov av. Thaum lub sij hawm sib dhos, qhov chaw thiab qhov chaw ntawm cov hlaws LED raug tshuaj xyuas kom tsis txhob muaj kev puas tsuaj xws li kev cuam tshuam, khawb, lossis kev sib txuas xoob. Tom qab kev sib sau ua ke, lub module qhov flatness, cov ntsiab lus sib txuas, thiab tag nrho cov kev tsim zoo raug kuaj xyuas kom ntseeg tau tias cov khoom haum thiab kev sib haum xeeb.
Lub hwj chim- ntawm kev sim thiab kev laus yog ua raws li cov kauj ruam tseem ceeb hauv kev ua kom cov khoom zoo. Lub hwj chim yog siv, thiab cov qauv kev sim yog siv los xyuas kom meej tias cov hlaws liab, ntsuab, thiab xiav LED teeb pom kev zoo; Kev kuaj xyuas kuj tseem ua rau qhov ci, xim tsis sib xws, thiab pom qhov tsis sib xws. Txhua yam teeb meem-xws li cov pixels tuag, qhov ci tsis sib xws, xim sib txawv, lossis cov duab tsis ua haujlwm hauv cheeb tsam-yuav tsum tau kho lossis hloov tam sim. Tom qab ua tiav qhov kev sim thawj zaug, cov qauv feem ntau tau siv lub sijhawm txuas ntxiv ntawm lub zog- ntawm kev laus kom nthuav tawm qhov muaj peev xwm soldering tsis xws luag lossis cov khoom tsis ua haujlwm. Thaum kawg, tsim nyog LED modules raug ntxuav, serialized, thiab ntim; lawv ces categorized los ntawm cov qauv rau warehouses los yog xa mus rau lub rooj sib txoos theem rau tag nrho LED zaub screen. Los ntawm cov txheej txheem suav nrog cov khoom sib txuas, kev sib txuas, kev sib dhos, kev kho kev tiv thaiv, kev ntsuas kev ua tau zoo, thiab kev laus, LED modules tau lees paub kom xa cov khoom zoo tshaj plaws thiab kev ua haujlwm ruaj khov.
