Cov xwm txheej feem ntau ntawm hluav taws xob Soldering Irons thiab lawv txoj kev tu
1) Cov hlau soldering tsis kub li tom qab tau powered
Thaum ntsib qhov txhaum no, koj tuaj yeem siv lub ohm thaiv ntawm lub multimeter los ntsuas ob qhov kawg ntawm lub ntsaws. Yog tias rab koob tsis txav mus, nws txhais tau hais tias muaj qhov qhib Circuit Court txhaum. Thaum lub ntsaws nws tus kheej tsis muaj qhov tsis ua haujlwm, koj tuaj yeem tshem tawm tus kov Bakelite thiab siv lub tshuab ntsuas ntau los ntsuas ob txoj hauv kev ntawm cov tub ntxhais hlau soldering. Yog tias rab koob tseem tsis txav mus, nws txhais tau hais tias cov tub ntxhais hlau soldering puas lawm thiab yuav tsum tau hloov nrog ib qho tshiab. Yog hais tias qhov kev tiv thaiv tus nqi ntawm ob txoj hauv kev ntawm cov tub ntxhais hlau soldering yog ntsuas li ntawm 2.5 kiloohms, nws txhais tau hais tias cov tub ntxhais hlau soldering yog qhov zoo. Qhov txhaum tshwm sim hauv lub hwj chim coj thiab ntsaws. Feem ntau cov faults yog txhuas hlau tawg thiab ntsaws kev sib cuag disconnection. Koj tuaj yeem txuas ntxiv siv Rx1 thaiv ntawm multimeter los ntsuas qhov ntsuas tus nqi ntawm cov hlau lead kom pom qhov teeb meem.
Txoj kev los hloov cov tub ntxhais hlau soldering yog kom loosen cov ntsia hlau uas txhim kho cov hlau lead hauv cov tub ntxhais hlau, tshem cov hlau lead, tshem tawm cov tub ntxhais hlau hlau los ntawm cov pas txuas txuas, tom qab ntawd ntxig cov hlau txuas tshiab ntawm tib lub ntsiab lus rau hauv. txuas tus pas nrig, thiab txhim kho cov hlau lead ntawm cov ntsia hlau kho. Thiab ua tib zoo txiav tawm cov xov hlau ntau kawg ntawm cov tub ntxhais hlau soldering los tiv thaiv ob txoj hauv kev luv luv.
Thaum ntsuas ob qhov kawg ntawm lub ntsaws, yog tias rab koob ntawm lub multimeter qhia ze rau 0 ohms, nws txhais tau hais tias muaj qhov cuam tshuam luv luv. Qhov taw tes ua txhaum feem ntau yog luv luv hauv lub ntsaws, lossis cov ntsia hlau crimping uas tiv thaiv lub zog hlau lead los ntawm kev tig tau poob, ua rau nws txuas nrog cov hlau lead ntawm cov tub ntxhais hlau soldering. Cov hlua hluav taws xob raug txiav thiab qhov luv luv tshwm sim. Thaum pom qhov ua txhaum ntawm qhov luv luv, nws yuav tsum tau ua raws li lub sijhawm thiab lub hwj chim yuav tsum tsis txhob tig rov qab kom tsis txhob hlawv lub fuse.
(2) Lub taub hau soldering yog them
Ntxiv rau qhov laj thawj yog vim li cas cov hlau txuas hluav taws xob vim tias cov hlua hluav taws xob txuas nrog hauv av hlau davhlau ya nyob twg, lwm qhov laj thawj yog vim li cas tom qab cov hlua hluav taws xob poob los ntawm cov hlua hlau txuas txuas, nws kov cov hlau hauv av dua, ua rau lub taub hau soldering puas lawm. raug nqi. Qhov kev ua txhaum no feem ntau yuav ua rau muaj hluav taws xob poob siab thiab cov khoom puas. Vim li no, nco ntsoov xyuas seb cov crimping screws puas xoob lossis ploj lawm. Yog tias nws poob los yog puas lawm, nws yuav tsum tau hloov nyob rau lub sijhawm (qhov kev ua haujlwm ntawm cov ntsia hlau crimping yog los tiv thaiv lub taub hau ntawm lub taub hau poob vim stretching thiab twisting ntawm lub hwj chim txhuas thaum siv)
(3) Lub taub hau hlau tsis "noj tin"
Tom qab siv mus ntev, lub taub hau hlau yuav dhau los ua oxidized thiab tsis lo rau lub tin. Qhov no yog qhov tshwm sim ntawm "hluav taws rau tuag", tseem hu ua "noj tin".
Thaum muaj qhov teeb meem inertia uas tsis "noj tin", koj tuaj yeem siv cov ntawv xuab zeb zoo los yog cov ntaub ntawv rov qab polished cov hlau nplaum los yog cov ntaub ntawv tawm tshiab stubble, thiab tom qab ntawd rov plated nrog solder txuas ntxiv siv nws.
(4) Lub qhov dej tshwm rau ntawm lub taub hau hlau
Thaum lub tshuab hluav taws xob siv hluav taws xob siv rau lub sijhawm, qhov pits lossis oxide zaj duab xis corrosion yuav tshwm sim ntawm cov hlau nplaum, ua rau cov duab ntawm cov hniav ntawm cov hlau taub hau hloov. Thaum ntsib cov xwm txheej zoo li no, koj tuaj yeem siv cov ntaub ntawv tshem tawm cov oxide txheej thiab cov pits, thiab tom qab ntawd muab phaj nrog tin, thiab koj tuaj yeem rov siv dua.
(5) Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm lub taub hau hlau, cov ntsiab lus hauv qab no yuav tsum tau them rau:
1) Nquag so lub taub hau nrog cov ntaub ntub dej los yog cov ntaub so ntub dej kom cov hlau taub hau zoo coated nrog cov tin thiab tiv thaiv corrosion ntawm cov hlau taub hau los ntawm cov seem seem.
2) Thaum vuam, rosin lossis qaug zog acidic flux yuav tsum tau siv.
3) Thaum welding tiav, cov seem seem ntawm cov hlua hlau yuav tsum tau muab khaws cia kom tsis txhob muaj cov txheej txheem oxide thaum rov ua dua.
