Nyob rau hauv cov txheej txheem ntawm kev tsim khoom, nws yeej ib txwm ntsib tias qee qhov ntawm cov hlaws teeb pom tau tias tsis tuaj yeem teeb pom kev thaum ib qho, ib txoj hlua, lossis ob peb txoj hlua ntawm cov hlaws teeb tsis tuaj yeem teeb thaum lub sijhawm kuaj tom qab mounting. Kab lus no yuav tham txog txoj kev vuam ntawm LED teeb hlaws.
Vuam txoj kev:
Ua ntej siv lub tshuab hluav taws xob hluav taws xob los hlawv ib co solder ntawm qhov zoo thiab qhov tsis zoo ntawm lub teeb hlaws (lub solder yuav tsum tsis txhob ntau dhau, txwv tsis pub, cov ntaub ntawv zoo thiab qhov tsis zoo yuav raug txuas ua ke thaum rhuab nrog rab phom cua kub), thiab tom qab ntawd siv rab phom kub cua kub rau qhov zoo thiab qhov tsis zoo ntawm tib lub sijhawm. Tom qab cov tin yog yaj, siv cov tweezers los muab cov electrodes zoo thiab tsis zoo ntawm lub teeb hlaws rau ntawm cov ntaub qhwv. Kev ua haujlwm yuav tsum ceev thiab raug, txwv tsis pub, rab phom kub yuav yaj lub pob yas ntawm LED thiab ua rau nws puas.
Thaum tsis muaj rab phom cua kub, cov txheej txheem vuam sib txawv tuaj yeem siv raws li cov qauv ntawm LED teeb hlaws thiab cov substrate siv. Lub SMD LED teeb hlaws pins yog semi-yas, uas yog, ib feem me me ntawm cov pins raug nthuav tawm ntawm ob sab ntawm lub teeb hlaws. Kuj tseem muaj cov pob yas tag nrho, uas yog, qhov zoo thiab tsis zoo electrodes ntawm lub teeb hlaws yog tag nrho nyob rau hauv qab ntawm lub nti.
Nws kuj yog yooj yim dua rau solder semi-yas teeb hlaws dai. Tsis tas li ntawd, ua ntej soldering, kub tin ntawm cov ntaub so ntswg (cov pins ntawm lub teeb hlaws yuav tsum tsis txhob raug soldered). Siv cov tweezers ntawm ob sab los tso cov ncej zoo thiab tsis zoo ntawm lub teeb hlaws rau ntawm cov ntaub qhwv. Siv koj cov ntiv tes los yog ib lub taub hau me me los nias lub teeb hlaws, thiab thaum kawg siv cov hluav taws xob soldering hlau kom ceev cov electrodes, thiab tib lub sij hawm, nias tus ntiv tes nrog lub zog tsim nyog (thaum cua sov, cov hlau nplaum yuav tsum tsis txhob ua. rub rov qab, thiab lub siab ntawm cov ntiv tes yuav tsum tsis txhob loj heev, txwv tsis pub nws yuav ua rau lub teeb hlaws dai).
Rau tag nrho cov-yas teeb hlaws, yog lub teeb bar substrate yog ib tug zoo tib yam Circuit Court board, ua ntej siv ib tug hniav los txhuam cov xim nyob ib ncig ntawm lub teeb hlaws pad kom nthuav tawm cov tooj liab hlau, thiab ces hlawv me ntsis tin ntawm lub ncoo, thiab solder lub. pad ua ntej. Tom qab ntawd muab cov hlau nplaum rau ntawm cov xov tooj tshiab uas tau muab tshem tawm thiab ua kom sov (tsis yog ntawm lub ncoo). Tom qab lub tin ntawm lub ncoo yog yaj, siv cov tweezers los tso cov khoom siv hluav taws xob ntawm lub teeb hlaws rau ntawm lub ncoo. Nias nws, thiab thaum kawg solder lub electrode nrog lub ncoo me me. Cov electrode nrog lub ncoo loj yuav tsum tau soldered ua ntej vim tias lub sijhawm cua sov ntev. Yog hais tias lub electrode yog soldered tom qab, lub teeb hlaws yuav zoo li overheated thiab puas.
Thaum soldering lub teeb hlaws nrog hluav taws xob soldering hlau, lub plhaub ntawm cov hluav taws xob soldering hlau yuav tsum tau zoo hauv av, thiab nws yog qhov zoo dua los hnav lub dab teg los tiv thaiv zoo li qub los tiv thaiv LED teeb hlaws los ntawm kev puas tsuaj los ntawm hluav taws xob thiab hluav taws xob zoo li qub. Tsis tas li ntawd, qhov ntxeev ntawm cov hlau soldering yuav tsum tau muab tso rau hauv ib lub voj voog ntawm cov nees kom nce qhov chaw sib cuag thiab ua kom lub sijhawm vuam luv.
