Kev ceev faj rau kev siv vuam siv hluav taws xob siab LED teeb hlaws rau lub zog txuag dej nyab
Lub zog muaj hwj chim loj LED teeb hlaws vuam txheej txheem yog kom ntseeg tau tias lub zog txuag dej nyab teeb yog lub hauv paus ntawm qhov ua tau zoo ntawm tag nrho cov khoom kab. Hom vuam hlau siv dab tsi hauv cov txheej txheem vuam yog cov txheej txheem thev naus laus zis, thiab cov hlau txuas siv yog LED nti (tseem hu ua nti) thiab tus pin sab nraud. Yog tias muaj teeb meem zoo nrog tus neeg xyuas pib nruab nrab ntawm kev sib txuas hluav taws xob, tag nrho lub zog txuag dej nyab teeb yuav raug muab pov tseg. Dab tsi yuav tsum tau them sai sai rau thaum vuam lub zog loj LED teeb hlaws?
Cov hlau no tuaj yeem yog xaim kub, xaim nyiaj, xaim hlau lossis tooj liab hlau. Ib txwm siv xov kub ruaj khov. Vim li cas ho tsis' peb tsis siv ob peb lwm cov xov hlau? Cov xov tooj tooj liab suav nrog ib leeg siv tooj liab tooj liab thiab tooj liab-plated tooj liab hlau. Tus nqi ntawm cov xov tooj tooj liab yog tus nqi qis, thiab qhov ntsuas xws li txhav, tawv, thiab tawm dag zog yog qhov siab. Txawm li cas los xij, cov xaim tooj liab tau yooj yim rau oxidize thiab cov txheej txheem kev sib koom ua ke tsis ruaj khov.
Muaj ob hom tseem ceeb ntawm kev siv hluav taws xob muaj zog zoo: kev siv lub tshuab ua kom siv lub tshuab ua kom sov thiab rov ua kom rov zoo dua. Kev siv lub tshuab ua kom haum yog haum rau txhua hom LEDs, thaum rov ua kom zoo dua qub tsuas yog tsim rau LEDs hauv cov thim rov qab-puab cov pob. Lens ntim cov LEDs tsis tuaj yeem hla rov qab siv dua, vim tias qhov ntsuas qhov ntsuas kub ntawm lub PC tsuas yog li 120 ° C.
Phau ntawv vuam siv hluav taws xob txuag hluav taws xob tsim hluav taws xob yog txhawm rau txuas cov pins thiab aluminium substrates ua ke los ntawm cov kub kub yaj yaj, thiab tib lub sijhawm tsho hauv qab ntawm LED tooj liab substrates thiab aluminium substrates nrog cov roj ua kom sov sov roj.
Txawm hais tias muaj cov hlau lead xaim lossis cov hlau tsis muaj cov hlau lead zoo rau siv los siv, cov ntsuas kub yuav tsum tsis pub tshaj 320 ℃ thiab lub sijhawm siv tshuaj yuav tsum raug tswj tsis pub dhau 1-3S. Txwv tsis pub, qhov kub thiab txias ntawm cov hlau txuas yuav ua rau PN txuas ntawm lub nti.
Cov txheej txheem soldering hlau yuav tsum tau ua haujlwm raws tus qauv txhawm rau tiv thaiv cov hlau ntxeev los ntawm kev hlawv cov pwm sab saum toj colloid lossis cov bracket, uas yuav cuam tshuam rau kev siv LED ib txwm muaj. Txhawm rau zam kom tsis txhob them lub teeb LED, cov hlau yuav tsum tau muab pov rau hauv av.
