LED Lamp Beads Moisture-proof Thiab Kho Txoj Kev

LED teeb hlaws noo-pov thawj thiab kev kho mob

 

 

Tsis ntev los no, lub caij nplooj ntoos hlav txias nyob rau sab qab teb tab tom los txog, ntau lub tuam txhab tsim khoom raug cuam tshuam, qhov laj thawj tseem ceeb yog vim li cas cov khoom siv raw hauv cov txheej txheem tsim cov dej noo hloov, yog li LED teeb hlaws yuav damp? Yuav ua li cas cuam tshuam rau qhov tsim ntawm qhov screen tom qab ntub dej?

 

01. Puas yog LED teeb hlaws dai damp?

 

Yog tias nws tau muab tso rau hauv qhov tsaus ntuj thiab ntub dej rau lub sijhawm ntev, LED teeb hlaws yuav damp. Nyob rau hauv tus txheej txheem ntawm damp, ib co kab ya raws nyob rau hauv cov dej vapor thiab huab cua yuav raug coj mus rau hauv lub LED pob, lub reflectors ntawm lub LED bracket yog silver-plated, cov nyiaj yuav oxidized, thiab cov nyiaj compound generated yog dub, txo. los yog poob lub peev xwm ntawm kev cuam tshuam, ua rau txo qis ntawm cov luminous flux ntawm LED, thiab cov dej noo no yuav ua rau muaj kev kub ntxhov thaum cov av noo siab hauv kev ua thiab vuam txheej txheem yuav ua rau muaj kev kub ntxhov los ua kev puas tsuaj rau cov khoom ya raws thaum nws undergoes cov txheej txheem kub, uas yog ib qho kev cuam tshuam loj heev. Yog tias muaj cov dej noo, cov dej noo nthuav tawm thaum lub sij hawm vuam, thiab cov wick yog qhov ua rau micro-bursting, uas ua rau tawg ntawm lub hauv paus tseem ceeb.

 

02. Moisture-proof kho txoj kev ntawm LED teeb hlaws dai

 

1. LED teeb hlaws tau ntim rau hauv cov hnab ntim dej noo thiab tiv thaiv zoo li qub aluminium ntawv ci, thiab cov pa tawm los ntawm kev nyem thiab tho lub hnab ntim khoom yuav tsum zam thaum tuav;

 

2. Thaum lub caij ntub dej, thaum lub hnab ntim dej tsis tau qhib, qhov kev pom zoo khaws cia yog: kub <30 degree, av noo <60%RH (zoo dua khaws cia rau hauv cov khoom pov thawj noo noo) thiab siv li ntawm 6 lub hlis;

 

3. Yog hais tias LED teeb hlaws hlaws tsis tau siv rau 6 lub hlis, nws raug nquahu kom nce qhov cub ua ntej siv nws dua, thiab dehumidification raug pom zoo (qhov pom zoo dehumidification mob yog 60 degree / 24H);

 

4. Tom qab lub ntim ntim tsis tau ntim, cov khoom siv tsis siv lub teeb ci LED yuav tsum tau nqus thiab kaw dua los yog muab tso rau hauv lub txee tsis muaj dej noo, thiab nws yog txwv tsis pub siv daim kab xev pob tshab, staples, thiab lwm yam rau kev sib khi yooj yim;

 

5. Ua ntej siv LED teeb hlaws dai, nws yog ib qho tsim nyog yuav tsum paub meej tias cov hlaws dai ntawm cov av noo ntawm daim npav muaj qhov tsis zoo. Yog tias cov hlaws tsis muaj dej noo ntau dua lossis sib npaug li 30% tsis muaj xim, ua kom qhov cub ci thiab dehumidification ua ntej siv (pom zoo de-cua sov: 60 degree / 24H)

 

6. Thaum lub teeb LED hlaws hlaws yog unpacked rau SMT, lawv tau raug mus rau lub rhiav ib puag ncig, thiab nws yog pom zoo kom tswj lub rhiav ib puag ncig: qhov kub <30 degree, thiab cov av noo yog tsawg tshaj li 60% rh;

 

7. Nyob rau lub caij ntuj sov, rau lub teeb vaj huam sib luag tom qab Reflow (ua ntej sib dhos lub teeb), nws raug nquahu kom muab tso rau hauv qhov chaw ua haujlwm rau 3-5 hnub.
