Feem ntau faults ntawm soldering hlau - soldering hlau kho txoj kev
1, soldering hlau tsis kub li tom qab energization
soldering hlau tsis kub li tom qab energized tias lub soldering hlau muaj ib tug tawg Circuit Court txhaum, qhov no tsis ua hauj lwm yuav tshwm sim nyob rau hauv ob peb qhov chaw ntawm lub plug ntawm lub soldering hlau, lub soldering hlau core yog phem, cov hlau lead ntawm soldering hlau core yog disconnected, lub hwj chim qaum ntawm lub soldering hlau yog disconnected.
2, lub taub hau hlau soldering tsis noj tin
Soldering hlau taub hau tsis noj "tin Park pom lub taub hau uas nyuam qhuav yuav hlau tsis trimming ncaj qha siv, ua rau lub taub hau hlau tsis nyob rau hauv lub tin. Ntev siv lub taub hau soldering hlau tsis nyob rau hauv lub tin, soldering hlau taub hau. tuag los tsim, yuav tsum luas.
3, hluav taws xob hlau them
soldering hlau them rau cov neeg ua haujlwm vuam yog qhov txaus ntshai heev, hnyav yuav ua rau hluav taws xob poob siab, yog li thaum pom qhov tshwm sim ntawm hluav taws xob soldering hlau them yuav tsum tam sim txiav tawm lub hwj chim los xyuas. Muaj ntau ntau yam vim li cas rau cov hlau soldering them soldering hlau fais fab qaum txuas nrog rau hauv av hlau davhlau ya nyob twg; lub hwj chim qaum los ntawm lub soldering hlau tub ntxhais davhlau ya nyob twg tawm thiab ces kov lub grounding hlau screws, uas ua rau lub soldering hlau taub hau them lub hwj chim lead winding los ntawm to; fais fab mov hauv av nws tus kheej to.
4, Soldering hlau taub hau qhov
Thaum cov hlau soldering siv rau qee lub sijhawm, lub taub hau hlau yuav tshwm pits, lossis txheej txheej oxidation corrosion, kom cov duab ntawm ntug ntawm lub taub hau hlau tau hloov. Thaum ntsib qhov xwm txheej zoo li no, tuaj yeem ua cov txheej txheem oxidized thiab cov pits tawm, thiab xa mus rau hauv cov duab qub, thiab tom qab ntawd plated nrog tin, tuaj yeem rov qab siv dua.
Txoj kev kho hlau soldering
1, soldering hlau tsis kub tom qab fais fab tu txoj kev
(1) Thaum lub tshuab hluav taws xob muaj zog, pom tias lub taub hau ntawm lub taub hau tsis kub, feem ntau yog cov hlua hluav taws xob tawm, lossis lub plawv ntawm cov kab hlau soldering puas lawm, ntsib qhov xwm txheej zoo li no, cov khoom siv multimeter tuaj yeem siv los ntsuas qhov ntsuas. ob qhov kawg ntawm lub hwj chim ntsaws ntsaws R × lkn thaiv, yog tias lub ntsuas ntsuas multimeter tsis txav mus, qhia tias muaj qhov tsis ua haujlwm hauv Circuit Court.
(2) Ua ntej xyuas lub ntsaws nws tus kheej seb cov hlau lead puas raug txiav, yog tias tsis yog, ces koj tuaj yeem tshem cov pos hniav ntoo tuav, thiab tom qab ntawd siv lub multimeter los ntsuas ob lub taub hau ntawm lub plawv hlau, yog tias lub multimeter pointer tseem tsis txav, qhia tias lub plawv hlau puas, koj yuav tsum hloov lub plawv hlau.
(3) 35W endothermic soldering hlau lub plawv nruab nrab ntawm ob qho tib si ntawm qhov kev tiv thaiv tus nqi ntawm 1. Skfl los yog li ntawd, yog tias qhov ntsuas qhov ntsuas tsis zoo yog qhov qub, nws txhais tau hais tias lub plawv hlau zoo, qhov tsis ua haujlwm tshwm sim hauv cov khoom siv hluav taws xob, thiab lub ntsaws nws tus kheej, feem ntau ntawm qhov txhaum yog cov hlau lead tawg. Yuav tsum tau hloov lub plawv hlau, yuav yog tshiab nrog cov specifications ntawm lub plawv hlau tso rau hauv lub connecting pas nrig, cov hlau lead yog tsau nyob rau hauv lub fixing screws, thiab zawm lub terminals, nyob rau tib lub sij hawm, yuav tsum nco ntsoov hais tias lub plawv hlau mus rau. hlau lead los txiav tawm qhov ntau dhau, txhawm rau tiv thaiv ob qho tib si luv luv-circuit.
2, hlau taub hau them txoj kev tu
(1) Yog vim li cas rau lub taub hau soldering hlau them txhaum, ntxiv rau lub hwj chim qaum yog tsis ncaj ncees lawm kev cob cog rua rau lub grounding hlau davhlau ya nyob twg, muaj lwm yam yog vim li cas, uas yog, thaum lub hwj chim qaum ntawm lub soldering hlau lub plawv nres, thiab ces. kov lub grounding hlau ntsia hlau, uas ua rau lub taub hau soldering hlau them.
(2) qhov tsis ua haujlwm zoo li no, yooj yim ua rau hluav taws xob poob siab, thiab yuav ua rau cov khoom puas tsuaj, txhawm rau tiv thaiv cov hlua hluav taws xob, yuav tsum tsis tu ncua xyuas cov hlau tuav ntawm lub siab kab ntsia hlau seb puas muaj xoob thiab ploj, xws li xoob, lossis poob, kom phim rau lub sijhawm.
