SMD LED teeb hlaws vuam txoj kev
Muaj ntau txoj kev vuam rau SMD LED teeb hlaws. Cov hauv qab no yog ib qho ntawm cov kev siv feem ntau rau kev siv. Ua ntej, siv lub tshuab hluav taws xob hluav taws xob los scald qee qhov 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 ces siv phom cua kub. Tshav kub qhov zoo thiab qhov tsis zoo nyob rau tib lub sijhawm. Tom qab lub tin yog yaj, siv tweezers los tso qhov zoo thiab qhov tsis zoo ntawm lub teeb hlaws rau ntawm cov ntaub qhwv.
Kev ua haujlwm yuav tsum ceev ceev thiab raug, txwv tsis pub, rab phom kub yuav yaj thiab puas lub pob yas ntawm LED.
Thaum tsis muaj rab phom cua sov, cov txheej txheem vuam sib txawv kuj tuaj yeem siv raws li cov qauv ntawm LED teeb hlaws thiab cov substrate siv. Cov pins ntawm SMD LED teeb hlaws yog cov yas ntim ib nrab, uas yog, ib feem me me ntawm cov pins raug nthuav tawm ntawm ob sab ntawm lub teeb hlaws, xws li cov khoom siv feem ntau 5730, 7020, 4014, thiab lwm yam.; tseem muaj tag nrho cov yas encapsulated, uas yog, qhov zoo thiab tsis zoo electrodes ntawm lub teeb hlaws yog tag nrho ntawm cov nti. hauv qab, xws li 3030 thiab lwm yam. Nws kuj tseem yooj yim dua rau vuam ib nrab lub teeb lub teeb hlaws xws li 7020. Tsis tas li ntawd, ua ntej soldering, koj yuav tsum sov me ntsis tin ntawm lub ncoo (pins ntawm lub teeb hlaws yuav tsum tsis txhob tinned), thiab siv tweezers ntawm ob sab los tso. qhov zoo thiab tsis zoo ncej ntawm lub teeb hlaws correspondingly. Nyob rau hauv lub ncoo, nias lub teeb hlaws nrog koj tus ntiv tes los yog ib tug me me ntswj ntsia hlau, thiab thaum kawg siv cov hluav taws xob soldering hlau kom sai li sai tau cov electrode raug, thiab nyob rau tib lub sij hawm nias down nrog lub zog tsim nyog ntawm tus ntiv tes (thaum cua sov, lub soldering. hlau tsis tuaj yeem rub rov qab thiab tawm mus, thiab lub siab ntawm tus ntiv tes yuav tsum tsis txhob loj dhau, txwv tsis pub cov hlaws teeb yuav puas).
Rau tag nrho cov yas-encapsulated teeb hlaws dai (xws li 3030), yog tias lub teeb sawb substrate yog ib lub rooj tsav xwm zoo tib yam, ua ntej siv cov hniav los txhuam cov xim nyob ib ncig ntawm lub teeb hlaws kom nthuav tawm cov xov tooj ntawm tes, thiab tom qab ntawd hlawv me ntsis tin rau. cov pads. solder lub electrode nrog lub ncoo loj, thiab tom qab ntawd muab cov hluav taws xob soldering hlau rau ntawm cov xov tooj liab tshiab uas tau muab tshem tawm kom sov (tsis tuaj yeem muab tso rau ntawm lub ncoo). Tom qab lub tin ntawm lub ncoo yog melted, siv tweezers los tso tus ncej sib thooj ntawm lub teeb hlaws rau ntawm lub solder. Lub siab me ntsis ntawm lub phaj tuaj yeem ua tiav, thiab thaum kawg solder cov electrodes nrog cov ntaub me me. Cov electrode nrog lub ncoo loj yuav tsum tau soldered ua ntej vim tias lub sijhawm cua sov yuav tsum tau ntev. Yog hais tias lub electrode yog soldered tom qab, lub teeb hlaws yog yooj yim overheated thiab puas.
Yog hais tias lub teeb bar substrate yog ib qho txhuas substrate, cov txheej txheem saum toj no tsis tuaj yeem siv, vim hais tias cov circuits siv aluminium substrate yog tsim los kom nyias nyias. Thaum vuam lub teeb hlaws ntawm hom teeb ci no, kev siv hluav taws xob tuaj yeem siv los txuas lub teeb hlaws, thiab aluminium phaj nyob rau sab nraum qab ntawm qhov zoo thiab tsis zoo electrode pads ntawm lub teeb hlaws tuaj yeem ua kom sov tib lub sijhawm. Tom qab lub tin ntawm lub ncoo yog melted, lub teeb hlaws dai rau ntawm lub ncoo. Cia li nias me ntsis. Lub tshuab cua sov tuaj yeem yuav los ntawm Taobao, lossis nws tuaj yeem hloov tau los ntawm lub zog hluav taws xob hluav taws xob loj (tsis pub tsawg dua 100W).
Thaum soldering lub teeb hlaws nrog cov hluav taws xob soldering hlau, lub plhaub ntawm cov hluav taws xob hlau yuav tsum tau zoo hauv av, thiab nws yog qhov zoo tshaj plaws los hnav lub tsho tiv thaiv zoo li qub los tiv thaiv hluav taws xob thiab hluav taws xob zoo li qub los ntawm kev puas tsuaj rau LED teeb hlaws. 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.
