Yuav ua li cas tiv thaiv hluav taws xob ntawm hluav taws xob hlau
Ua rau hluav taws xob to ntawm hluav taws xob soldering hlau
Yog vim li cas rau qhov to ntawm lub soldering hlau yog feem ntau yog tshwm sim los ntawm cov to ntawm lub soldering hlau core.
Cov tub ntxhais hlau soldering yog tsim los ntawm cov cua sov xaim, cov txheej txheem insulating thiab ib txheej insulating. Thaum cov txheej txheej insulating raug ya raws los yog kev laus rau lub sijhawm ntev, cov txheej txheem rwb thaiv tsev yuav txo qis, uas ua rau cov xau ntawm cov tub ntxhais hlau soldering. Tom qab ntawd nws dhau los ntawm lub tshav kub hloov lub plhaub ntawm cov hluav taws xob soldering hlau thiab lub taub ntawm cov hlau soldering.
Tus kov ntawm cov hluav taws xob soldering hlau tseem yuav xau hluav taws xob tom qab kev laus dhau lawm.
Tom qab hluav taws xob xau tshwm sim nyob rau hauv cov hluav taws xob soldering hlau, qhov teeb meem loj heev, thiab nws yooj yim heev ua rau hluav taws xob poob siab, uas yog qhov tsis zoo rau tib neeg thiab cov khoom siv hluav taws xob thiab hluav taws xob yuav tsum tau kho. Thov hloov cov tub ntxhais hlau soldering thiab cov khoom xau tam sim ntawd, thiab hloov lawv tag nrho yog tias tsim nyog.
Yuav ua li cas tiv thaiv hluav taws xob ntawm hluav taws xob hlau
1. Ua ntej kho lub multimeter mus rau AC voltage iav, txuas cov kev sim dub coj mus rau hauv av, thiab txuas cov kev sim liab coj mus rau qhov kawg ntawm cov hlau hluav taws xob. Saib seb lub multimeter puas muaj kev nyeem ntawv. Yog tias muaj kev nyeem ntawv, nws ua pov thawj tias cov hluav taws xob soldering hlau tau xau thiab yuav tsum tau kho.
2. Disassemble cov hluav taws xob soldering hlau, nrhiav cov hauv av hauv av, thiab tom qab ntawd nrhiav qhov kev tiv thaiv txuas nrog lub rooj tsav xwm hauv Circuit Court raws cov xaim hauv av, thiab ntsuas nws cov nqi tiv thaiv. Yog tias nws siab tshaj 5 ohms, nws raug txiav txim siab kom hlawv thiab yuav tsum tau hloov pauv (qhov xau yog qhov loj heev. Qee zaum, lub resistor puas lawm), thiab yog tias tus nqi tsis kam yog qhov qub, thov paub meej tias qhov kev sib cuag ntawm cov soldering. hlau plug yog zoo.
3. Tshem tawm cov hluav taws kub hnyiab thiab hloov nrog ib qho tshiab. Nco ntsoov tias txawm hais tias tus nqi tsis kam ntawm qhov resistor yog 0 ohms, nws ua lub luag haujlwm tiv thaiv thiab yuav tsum tsis txhob luv luv ntawm no!
4. Tom qab hloov, siv lub multimeter kom paub meej tias qhov kev tiv thaiv tus nqi ntawm qhov chaw taws teeb ntsuas ntawm qhov tsis kam thiab hauv av.
5. Tom qab kev kho tiav lawm, siv lub tshuab multimeter kom paub meej tias qhov kev tiv thaiv tus nqi ntawm lub taub hau hlau thiab cov xaim hauv av. Yog tias tus nqi tiv thaiv nyob rau hauv 2 ohms, nws ua pov thawj tias kev kho tau zoo.
