Tham txog kev tsim thiab ntim tshuab ntawm LED teeb hlaws
1. Cov txheej txheem ntau lawm
1.1 Kev Tu: Siv ultrasonic los ntxuav PCB lossis LED bracket thiab ziab nws.
1.2 Mounting: Tom qab lub hauv qab electrode ntawm LED tuag (loj wafer) yog npaj nrog nyiaj kua nplaum, nws yog nthuav, thiab nthuav tuag (loj wafer) yog muab tso rau ntawm lub pos siv lead ua lub rooj, thiab ib tug pos siv lead ua cwj mem yog siv nyob rau hauv lub microscope. Ib qho yog ntsia rau ntawm cov ntaub qhwv sib xws ntawm PCB lossis LED bracket, thiab tom qab ntawd sintered los kho cov kua nplaum nyiaj.
1.3 Siab vuam: Siv cov txhuas hlau los yog kub hlau bonder los txuas cov electrode rau LED tuag los ua cov hlau lead rau kev txhaj tshuaj tam sim no. Yog hais tias lub LED yog ncaj qha mounted rau PCB, ib tug txhuas hlau vuam tshuab feem ntau yog siv. (Kev tsim lub teeb dawb TOP-LED xav tau ib lub xov hlau kub)
1.4 Encapsulation: Tiv thaiv LED tuag thiab sib txuas cov xov hlau nrog epoxy los ntawm kev xa tawm. Dispensing kua nplaum rau ntawm lub rooj tsavxwm PCB muaj cov kev cai nruj ntawm cov duab ntawm cov colloid tom qab kho, uas yog ncaj qha ntsig txog qhov ci ntawm lub teeb ci tiav. Cov txheej txheem no tseem yuav ua haujlwm ntawm cov ntsiab lus phosphors (dawb LEDs).
1.5 Soldering: Yog hais tias lub backlight qhov chaw yog SMD-LED los yog lwm yam ntim LEDs, cov LEDs yuav tsum tau soldered rau lub PCB ua ntej cov txheej txheem los ua ke.
1.6 Zaj duab xis txiav: Tuag-txiav ntau yam diffusion films, reflective films, thiab lwm yam yuav tsum tau rau lub backlight nrog ib tug punch.
1.7 Kev sib dhos: Manually nruab ntau yam ntaub ntawv ntawm lub teeb rov qab rau hauv txoj haujlwm kom raug raws li qhov xav tau ntawm cov duab kos.
1.8 Kev Xeem: Tshawb xyuas seb cov duab hluav taws xob tsis zoo ntawm lub teeb pom kev zoo thiab qhov sib xws ntawm lub teeb pom kev zoo.
1.9 Ntim: Cov khoom tiav tau ntim thiab khaws cia raws li xav tau.
2. Ntim txheej txheem
2.1 Lub luag haujlwm ntawm LED ntim
Nws yog txhawm rau txuas cov hlau lead sab nraud rau cov electrode ntawm LED nti, tiv thaiv LED nti tib lub sijhawm, thiab ua lub luag haujlwm hauv kev txhim kho lub teeb pom kev zoo. Cov txheej txheem tseem ceeb yog mounting, siab vuam, thiab ntim.
2.2 LED pob daim ntawv
LED ntim cov ntaub ntawv tuaj yeem hais tau ntau yam, feem ntau raws li kev thov sib txawv los txais yuav qhov sib thooj sab nraud, ntsuas kub dissipation thiab teeb pom kev zoo. LEDs tau muab faib ua Teeb-LED, TOP-LED, Sab-LED, SMD-LED, High-Power-LED, thiab lwm yam.
