Kev ceev faj rau kev siv 1W 3W siab zog LED nti
High-power LED teeb hlaws yog ib hom LED teeb hlaws. Piv nrog lub zog qis LED teeb hlaws, lub zog loj LED teeb hlaws muaj zog dua, ci ntsa iab thiab tus nqi siab dua. Qhov ntsuas tam sim no ntawm lub teeb hluav taws xob qis qis yog 20mA, thiab cov uas muaj qhov ntsuas tam sim no siab dua 20mA tuaj yeem suav tias yog lub zog siab.
Raws li qhov tshwm sim ntsuab, ib puag ncig tus phooj ywg thiab txuag hluav taws xob, nws yog dav siv hauv tsheb teeb, teeb nyem, teeb thiab lwm qhov chaw. Yog vim li cas vim li cas LED high-power yog li hu ua tsuas yog rau cov uas tsis muaj zog LEDs. Kuv tau sau tseg peb cov qauv kev faib tawm: Ib qho tuaj yeem muab faib ua 0.5W, 1W, 3W, 5W, 10W .... 100W raws li lub zog loj. Nws txawv, nyob ntawm lub zog tag nrho ntawm cov khoom ntim molded.
High-power LED teeb hlaws yuav tsum xyuam xim rau cov ntsiab lus hauv qab no:
1. Tus neeg siv khoom yuav tsum paub meej tias qhov zoo thiab qhov tsis zoo ntawm lub zog loj coj lub teeb hlaws ua ntej vuam lub zog loj coj lub teeb hlaws, txhawm rau tiv thaiv lub zog siab lub zog coj teeb hlaws tsis tuaj yeem teeb pom kev lossis hlawv tawm. Yog hais tias qhov tsis zoo electrode thim rov qab, nws yog ib qho yooj yim los hlawv qhov thim rov qab (qhov thim rov qab muaj qhov poob siab loj).
2. Lub reflow soldering kub cheeb tsam ntawm high-power LED teeb hlaws yuav tsum siab tshaj 6 qhov chaw kub, uas yog, lub sab sauv 6 qhov kub thiab txias zones 6 qhov kub thiab txias, thiab cov kiv cua txias tswj kev ua haujlwm zoo. Nyob rau hauv thaum ntxov hnub, nws yog tsis yooj yim sua rau ib co neeg siv reflow soldering nrog 3 down thiab 5 down. Muaj ob peb qhov chaw kub thiab txias lub sij hawm luv luv (qhov tseeb, reflow soldering yog txheej txheem ntawm cua sov thiab dehumidification los ntawm qhov kub thiab txias cheeb tsam mus rau qhov kub kub solder sib koom ua ke.
3. High-power LED teeb hlaws dai kom zoo dua nyob rau hauv ib puag ncig ntawm 40-60 degrees, ua tib zoo saib xyuas cov dej-pov thawj thiab tiv thaiv kom tsis txhob ya raws. Ua ntej reflow soldering, siv lub qhov cub 60-degree los tsim kua muag qhib lub pob txheej kom dehumidify rau ntau tshaj 6 teev (cov khoom tsis zoo yog siv tsis tau ntev).
4. Vim qhov tshwj xeeb ntawm high-power LED teeb hlaws, sim deviate me ntsis rau sab me me (tsis zoo ncej, trimmed ntug) thaum vuam.
5. Lub reflow soldering ceev ntawm high-power LED teeb hlaws yuav tsum tau tswj ntawm 300-500 mm / min. Piv txwv li 6 thaj chaw kub, muaj cov hlau lead-tin solder pob qij txha ntawm 220 degrees.
6. High-power coj teeb hlaws dai xav tias 7 qhov chaw kub, nrog cov hlau lead-tin solder pob qij txha ntawm 220 degrees.
7. High-power LED teeb hlaws dai yog siv rau xim sib cais BIN, voltage tis thiab kuj. Thaum ua cov chip mounter, xyuam xim rau kev siv cov xim sib cais BIN. Tsis txhob muab cov khoom ntawm cov xim sib txawv ntawm ob peb Feida tib lub sijhawm. Tshaj tawm yog paj.
8. High-power LED teeb hlaws hlaws tiv thaiv luv luv (lub teeb hluav taws xob) thaum lub pob zeb dawb txav ntawm lub tin, thiab nws yuav tsis teeb thaum qhov kev sib cuag tsis zoo, lossis tsis ruaj khov (nws yuav tsis teeb thaum nws qhib) .
9. Qhov teeb meem ntawm cov kuab tshuaj ntxuav ntawm high-power LED teeb hlaws dai, tiv thaiv dej cawv, Tianna dej, thiab lwm yam, tuaj yeem yooj yim ua rau discoloration ntawm lub hauv qab ntawm lub teeb, uas ua rau discoloration ntawm high-power LED teeb hlaws dai. Dawb hluav taws xob roj yog pom zoo.
10. High-power LED teeb hlaws yog siv los tiv thaiv electrostatic tawg thaum siv ferrochrome teeb, thiab lub zog loj LED teeb hlaws dai hauv zos rhuab tsis sib xws thiab tuag. Lub ferrochrome, workbench, thiab reflow soldering yuav tsum tau grounded, thiab lub zog ntawm ferrochrome yog nruab nrab.
