1. Anti-static

Lub rooj sib dhos zaub yuav tsum muaj kev ntsuas zoo tiv thaiv zoo li qub.Dedicated anti-static av, anti-static pem teb, anti-static soldering hlau, anti-static rooj lev, anti-static nplhaib, anti-static khaub ncaws, av noo tswj, khoom siv hauv av (tshwj xeeb tshaj yog cov ko taw cutter), thiab lwm yam. yuav tsum tau, thiab yuav tsum tau xyuas tsis tu ncua nrog ib tug static meter .

2. Tsav Circuit Court tsim

Kev teeb tsa ntawm tus tsav tsheb IC ntawm tus tsav tsheb Circuit Court board ntawm cov zaub module kuj tseem cuam tshuam qhov ci ntawm LED.Txij li thaum cov zis tam sim no ntawm tus tsav tsheb IC raug xa mus ntev ntawm PCB pawg thawj coj saib, qhov hluav taws xob poob ntawm txoj kev sib kis yuav loj dhau, uas yuav cuam tshuam rau qhov kev ua haujlwm ib txwm muaj ntawm LED thiab ua rau nws qhov ci ntsa iab.Peb feem ntau pom tias qhov ci ntsa iab ntawm LEDs nyob ib ncig ntawm cov zaub module yog qis dua hauv nruab nrab, uas yog vim li cas.Yog li ntawd, txhawm rau kom ntseeg tau qhov sib xws ntawm qhov screen brightness, nws yog ib qho tsim nyog los tsim tus tsav tsheb Circuit Court faib daim duab.

3. Tsim tus nqi tam sim no

Lub nominal tam sim no ntawm LED yog 20mA.Feem ntau, nws raug pom zoo tias qhov siab tshaj plaws ua haujlwm tam sim no tsis pub ntau tshaj 80% ntawm tus nqi nominal.Tshwj xeeb tshaj yog rau cov lus qhia nrog lub suab me me, tus nqi tam sim no yuav tsum tau qis dua vim qhov tsis zoo ntawm cov cua sov dissipation.Raws li kev paub dhau los, vim qhov tsis sib xws ntawm qhov nrawm nrawm ntawm cov xim liab, ntsuab, thiab xiav LEDs, tam sim no tus nqi ntawm cov xiav thiab ntsuab LEDs yuav tsum raug txo kom raws li lub hom phiaj kom muaj qhov sib xws ntawm qhov sib npaug ntawm cov xim dawb ntawm lub vijtsam. tom qab siv mus ntev.

4. Cov teeb sib xyaw

LEDs ntawm tib xim thiab sib txawv brightness theem yuav tsum tau muab sib xyaw, los yog muab tso rau raws li lub teeb insertion daim duab tsim raws li txoj cai discrete los xyuas kom meej qhov sib xws ntawm brightness ntawm txhua xim ntawm tag nrho cov screen.Yog tias muaj teeb meem hauv cov txheej txheem no, lub teeb ci hauv zos ntawm cov zaub yuav tsis sib haum, uas yuav cuam tshuam ncaj qha rau cov nyhuv ntawm LED zaub.

5. Tswj lub verticality ntawm lub teeb

Nyob rau hauv-kab LEDs, yuav tsum muaj cov txheej txheem txaus los xyuas kom meej tias cov LED yog perpendicular rau lub PCB board thaum dhau lub cub tawg.Txhua qhov sib txawv yuav cuam tshuam rau qhov ci ntsa iab ntawm LED uas tau teeb tsa, thiab cov xim thaiv nrog qhov ci tsis sib xws yuav tshwm sim.

6. Wave soldering kub thiab lub sij hawm

Qhov kub thiab lub sij hawm ntawm yoj pem hauv ntej vuam yuav tsum nruj me ntsis tswj.Nws raug pom zoo tias qhov ntsuas kub ua ntej yog 100 ℃ ± 5 ℃, thiab qhov kub siab tshaj plaws yuav tsum tsis pub tshaj 120 ℃, thiab qhov kub ua ntej yuav tsum nce siab.Lub vuam kub yog 245 ℃ ± 5 ℃.Nws raug pom zoo tias lub sijhawm yuav tsum tsis pub tshaj 3 vib nas this, thiab tsis txhob vibrate lossis poob siab lub LED tom qab lub cub tawg kom txog thaum nws rov qab mus rau qhov kub thiab txias.Qhov ntsuas kub tsis tu ncua ntawm lub tshuab yoj soldering yuav tsum tau kuaj xyuas tsis tu ncua, uas yog txiav txim los ntawm cov yam ntxwv ntawm LED.Overheating lossis fluctuating kub yuav ua rau lub LED puas ncaj qha los yog ua rau cov teeb meem tsis zoo, tshwj xeeb tshaj yog rau cov me me puag ncig thiab oval LEDs xws li 3 hli.

7. Vuam tswj

Thaum lub LED zaub tsis teeb, feem ntau muaj ntau tshaj 50% qhov tshwm sim los ntawm ntau hom virtual soldering, xws li LED tus pin soldering, IC tus pin soldering, tus pin header soldering, thiab lwm yam. nruj kev txhim kho cov txheej txheem thiab ntxiv dag zog rau kev soj ntsuam zoo los daws.Kev kuaj vibration ua ntej tawm hauv lub Hoobkas kuj yog ib txoj kev tshuaj xyuas zoo.

8. Thaum tshav kub kub dissipation tsim

LED yuav ua kom muaj cua sov thaum nws ua haujlwm, qhov kub thiab txias dhau yuav cuam tshuam rau qhov attenuation ceev thiab ruaj khov ntawm LED, yog li lub tshav kub dissipation tsim ntawm PCB board thiab qhov cua thiab cua kub dissipation tsim ntawm lub txee yuav cuam tshuam rau kev ua haujlwm ntawm LED.
