Cov txheej txheem tsim khoom rau cov khoom sib txawv ntawm LED zaub screen txawv. Noj LED modules ua piv txwv, thawj kauj ruam yog tsim thiab fabrication ntawm PCB board. Tom qab ntawd, cov chips LED, resistors, capacitors, thiab lwm yam khoom siv tau raug xa mus rau PCB pawg thawj coj siv siv tshuab nto mount (SMT). Reflow soldering thiab aging tests yog tom qab ntawd ua kom ntseeg tau qhov ci ntsa iab thiab xim sib xws rau txhua pixel.
Hauv kev tsim cov neeg tsav tsheb fais fab mov thiab tswj qhov system, lub hom phiaj yog nyob rau hauv Circuit Court tsim thiab precision sib dhos. Tom qab SMT thiab cov khoom siv soldering, PCB pawg thawj coj saib xyuas kev ua haujlwm thiab siab - qhov ntsuas kub ntawm kev laus kom paub tseeb tias nws ruaj khov nyob rau hauv qhov sib txawv voltage thiab load. Lub caij no, cov txheej txheem sab nrauv feem ntau yog tsim los siv cov txheej txheem stamping lossis tuag casting, ua raws li kev kho saum npoo los txhim kho cov cua sov thiab kev tiv thaiv.
Kev tsim cov txheej txheem txee thiab cov khoom siv pabcuam leans ntxiv rau cov txheej txheem machining. Aluminium alloys los yog steel raug txiav, khoov, welded, los yog tuag- nrum, thiab ces kho nrog tshuaj tsuag los yog anodizing los txhim kho corrosion kuj thiab zoo li. Thoob plaws hauv cov txheej txheem tsim khoom, cov txheej txheem kev sim nruj yog siv, xws li kev ntsuas dej tsis zoo, kev vibration, thiab kev laus, kom ntseeg tau tias muaj kev ntseeg siab thiab ua haujlwm ntev ntawm cov khoom kawg hauv kev siv tswv yim.
