SMD LED nti ntim txheej txheem qhia
Kev ua haujlwm tshwj xeeb ntawm LED ntim
1. Ua ntej yog LED nti tshuaj xyuas
Kev tshuaj xyuas microscopic: Txawm hais tias muaj kev puas tsuaj thiab pitting ntawm qhov chaw ntawm cov khoom, seb qhov loj thiab qhov loj ntawm LED nti electrode ua tau raws li cov txheej txheem yuav tsum tau ua; seb tus qauv electrode puas tiav.
2. Lub tshuab nthuav dav nthuav tawm zaj duab xis
Txij li cov chips LED tseem tab tom npaj nruj tom qab dicing, lub suab yog me me, uas tsis haum rau kev ua haujlwm ntawm cov txheej txheem tom ntej. Peb siv ib zaj duab xis expander los nthuav cov zaj duab xis ntawm lub bonded nti. Qhov kev ncua deb ntawm LED chips yog ncav cuag li 0.6 hli, thiab phau ntawv nthuav dav kuj siv tau, tab sis nws yog ib qho yooj yim los ua teeb meem phem xws li nti poob thiab pov tseg.
3. Kev faib tawm
Muab cov kua nplaum nyiaj los yog cov nplaum nplaum rau ntawm qhov chaw sib txuas ntawm LED bracket. Qhov nyuaj ntawm cov txheej txheem yog nyob rau hauv kev tswj tus nqi ntawm cov kua nplaum. Muaj cov ncauj lus kom ntxaws thev naus laus zis rau qhov siab ntawm colloid thiab txoj haujlwm ntawm cov kua nplaum. Vim tias cov kua nplaum nyiaj thiab cov nplaum nplaum muaj cov kev cai nruj heev ntawm kev khaws cia thiab siv, kev sib xyaw, thiab siv sijhawm ntawm cov kua nplaum nyiaj yog qhov tseem ceeb uas yuav tsum tau them nyiaj rau hauv cov txheej txheem.
4. Npaj kua nplaum
Nyob rau hauv sib piv rau cov kua nplaum dispensing, cov kua nplaum npaj yog siv lub kua nplaum npaj tshuab ua ntej lub tsho tiv no nyiaj kua nplaum nyob rau hauv lub rov qab electrode ntawm lub LED, thiab ces nruab lub LED nrog cov nyiaj kua nplaum rau sab nraum qab ntawm lub LED bracket. Qhov ua tau zoo ntawm kev npaj kua nplaum yog ntau dua li cov kua nplaum dispensing, tab sis tsis yog txhua yam khoom tsim nyog rau cov txheej txheem kua nplaum.
5. Phau ntawv splint
Muab cov nti LED nthuav dav rau ntawm lub rooj sib dhos ntawm lub rooj zaum, muab lub teeb ci LED nyob rau hauv qhov chaw teeb tsa, thiab muab cov chips LED ib qho los ntawm ib qho mus rau qhov sib txuas nrog ib rab koob hauv qab lub tshuab tsom. Piv nrog rau cov khib nyiab mounting tsis siv neeg, phau ntawv tho zaj duab xis muaj qhov zoo dua, nws yooj yim los hloov cov chips sib txawv txhua lub sijhawm, thiab nws tsim nyog rau cov khoom uas yuav tsum tau nruab ntau lub chips.
