Ua ntej: LED PIN txoj kev ua qauv
1. Nws yog ib qho tsim nyog rau 2 hli los ntawm gel kom khoov lub bracket.
2. Kev sib tsoo qhov yuav tsum ua tiav nrog ib tug clamp los yog ib tug kws tshaj lij.
3. Kev txhim kho sab nrauv yuav tsum tau ua kom tiav ua ntej qhov vuam siv.
4. Kev txhim kho sab nrauv yuav tsum xyuas kom cov yas qiv thiab cov kis tau zoo ib yam li lub rooj tsavxwm.
Qhov thib ob, them nyiaj rau cov hlua khau LED thiab txiav ko taw
Vim hais tias tus tsim yuav tsum tau khoov thiab txiav taw, thaum khoov thiab txiav cov LED, qhov chaw ntawm txoj hlua khoov thiab txiav tawm yog ntau tshaj 3 hli ntawm qhov qis hauv qab ntawm cov gel.
Cov khoov nyom yuav tsum tau muab ua ntej welding. Thaum siv lub teeb plug-in teeb, lub suab ntawm lub pcb board qhov sib tshuam ua rau tus pin pin suab. Thaum txiav qhov ko taw, qhov kev sib txuas ntawm kev siv lub tshuab ua rau lub siab siv hluav taws xob muaj zog, yog li lub tshuab yuav tsum muaj kev ruaj ntseg thiab ua hauj lwm los tiv thaiv kev ua haujlwm (lub tsom iav raug ntaus kom tua hluav taws xob).
Thib peb, LED ntxuav
Yuav tsum tau saib xyuas tshwj xeeb yog thaum tu cov kua tshuaj nrog tshuaj, vim qee cov tshuaj muaj peev xwm tuaj yeem ua rau ntawm lub gel thiab ua rau tsis muaj pa taws xws li trichlorethylene, acetone, thiab cov zoo li. Nws yuav tsum wiped thiab raus hauv ethanol kom tsawg dua 3 feeb ntawm chav tsev kub.
Qeb plaub, Cov kev tiv thaiv kab mob ntawm cov roj tiv thaiv kab mob
Overcurrent tiv thaiv yuav siv tau los muab LED series tiv resistors kom tswj lub lag luam.
Tus nqi kuj yog xam raws li: R = (VCC-VF) / YOG
VCC yog lub zog mov | voltage regulator voltage, VF yog lub LED tsav voltage, YOG yog qhov tam sim no
Tsib, LED welding conditions
1. Cov kav hlau (soldering iron soldering): Cov kav hlau ci (30W) yuav tsum tsis txhob sov siab tshaj 300 tawm C, lub sij hawm siv tsis ntev tshaj 3 seconds, thiab txoj haujlwm nyob rau hauv qhov kav dej yog qhov tsawg kawg yog 2 hli ntawm lub pob tag.
2. Kev yoj tes: Lub siab tshaj plaws ntawm kev sib dhos saum nruab ntug yog 260 ° C, lub sijhawm laug sij hawm tsawg tshaj li 5 feeb, thiab qhov chaw nyob sib dhos yog tsawg kawg yog 2 hli ntawm lub pob tawm.
