11. Kev Paub Txog

LED vuam qee qhov kev paub thiab ceev faj

Cov cuab yeej thiab cov khoom siv raw: coj hluav taws xob hlau nrog lub nplhaib electrostatic, hnav cov khaub ncaws electrostatic, khau static ultrasonic

tshuab lossis cawv hloov.Lub vuam kub yog nyob ib ncig ntawm 260, lub sij hawm yog tswj nyob rau hauv 3S, lub vuam taw tes yog

saum toj no 3.5MM los ntawm hauv qab ntawm cov gel, thiab cov hlau soldering yuav tsum tau grounded.Thaum welding, nws yog qhov zoo tshaj rau welding

tsis zoo electrode ntawm lub teeb-emitting raj ua ntej, thiab ces solder lub zoo electrode ntawm lub teeb-emitting raj.

Thov coj welding.Nyob rau hauv cov ntaub ntawv ntawm lub hwj chim-on, tsis txhob high-temperature ua hauj lwm saum 80. Yog hais tias muaj high-temperature.

kev khiav hauj lwm, cua sov yuav tsum tau ua.anti-static:

(1) Txhua tus neeg ua haujlwm koom nrog hauv xiav, ntsuab, dawb thiab ntshav LEDs yuav tsum tau siv cov kev ntsuas tiv thaiv zoo li qub, xws li: nrog rau electrostatic

nplhaib, khaub ncaws zoo li qub, thiab khau zoo li qub.

(2) Thaum siv lub nplhaib hlau electrostatic, lub nplhaib electrostatic yuav tsum tau ua hauv av, thiab qhov sib txawv ntawm qhov

av xaim thiab av xaim yuav tsum tsis pub tshaj 5V lossis impedance yuav tsum tsis pub tshaj 25 ohms.

(3) Ib qho av xaim yuav tsum tau nruab rau ntawm ob lub tshuab ua haujlwm thiab lub rooj ua haujlwm.

Thaum siv LEDs, qhov tam sim no yuav tsum tsis pub tshaj 20MA, nyiam dua 15-18MA.

Thaum txhim kho lub LED, nws raug nquahu kom siv lub tes tsho qhia rau nws. Tsis txhob nruab nws nrog cov hlau lead deformed.

Ua ntej qhov kub thiab txias rov qab mus rau qhov qub, LED yuav tsum raug tiv thaiv los ntawm kev co lossis lwm yam quab yuam.

9.Yog tias koj xav tau ntxuav lub LED, nws raug nquahu kom siv ultrasonic ntshiab coj. Yog tias tsis muaj ultrasonic tu tshuab, koj

tuaj yeem siv cawv hloov pauv, tab sis lub sijhawm ntxuav yuav tsum tsis pub tshaj ib feeb.

Lus Cim: Tsis txhob siv cov kuab tshuaj organic (xws li acetone, thiab dej Tianna) los ntxuav lossis so lub LED colloid.

Lub illuminating yog txawv txav los yog sab hauv ntawm lub colloid yog tawg, ua rau kev puas tsuaj rau lub puab kub hlau ntawm lub coj thiab lub wafer.

10.Thaum tus coj yog khoov los yog folded, thov tsis txhob mus ze rau cov gel. Khaws qhov deb ntawm cov kua nplaum thiab cov gel kom ntau

mas 3mm. Txwv tsis pub, lub bracket nyob rau hauv lub coj colloid yuav tsum tau muab cais los ntawm lub kub hlau. Tus naj npawb ntawm folds ntawm tus pin ntawm

tib qhov chaw tsis tuaj yeem tshaj peb. Khoov rau 90 thiab rov qab mus rau qhov qub qub ib zaug.
