Kev taw qhia txog cov ntsiab lus ntawm hluav taws xob soldering hlau
Vuam yog ib qho mob uas tsuas yog ib qho me me ntawm cov tin yog soldered ntawm qhov sib koom ua ke, ua rau muaj kev sib cuag tsis zoo thiab qee zaus ntawm thiab tawm. False welding txhais tau hais tias nws zoo li welded rau saum npoo, tab sis qhov tseeb nws tsis yog. Qee zaum cov hlau lead tuaj yeem rub tawm los ntawm kev sib koom ua ke los ntawm kev rub tawm ntawm tes. Ob qhov xwm txheej no yuav ua rau muaj teeb meem loj rau kev debugging thiab kev saib xyuas ntawm cov khoom siv hluav taws xob. Ob qho xwm txheej no tsuas yog zam tau nrog kev siv dav dav, ua tib zoo siv vuam. Thaum vuam Circuit Court boards, nco ntsoov tswj lub sijhawm. Yog tias nws ntev dhau lawm, lub rooj tsav xwm hluav taws xob yuav raug hlawv lossis daim ntawv tooj liab yuav poob. Thaum tshem cov khoom los ntawm lub rooj tsav xwm hauv Circuit Court, koj tuaj yeem muab cov hlau nplaum rau ntawm qhov sib koom ua ke thiab rub tawm cov khoom tom qab cov tin ntawm cov khoom sib koom ua ke. Qhov kub ntawm cov hlau soldering muaj ib qho kev sib raug zoo nrog lub ntim, cov duab, ntev, thiab lwm yam ntawm cov hlau taub hau. Thaum lub ntim ntawm cov hlau taub hau yog qhov loj, lub sijhawm tuav yuav ntev dua. Tsis tas li ntawd, txhawm rau hloov kho raws li qhov yuav tsum tau muaj ntawm cov khoom siv vuam sib txawv, cov duab ntawm cov lus qhia ntawm cov hlau sib txawv. Feem ntau muaj xws li cone, chisel, ncig bevel, thiab lwm yam.
Siv lub ohm teeb tsa ntawm multimeter los ntsuas seb puas muaj qhov qhib lossis luv luv ntawm ob qho kawg ntawm lub ntsaws, thiab tom qab ntawd siv Rx1000 lossis Rx10000 teeb tsa los ntsuas qhov tsis kam ntawm lub ntsaws thiab lub plhaub. Yog tias tus taw tes tsis txav los yog qhov kev tawm tsam ntau dua 2-3MΩ, nws tuaj yeem siv tau yam tsis muaj qhov xau. Cov tub ntxhais hlau ntawm cov cua sov hauv hluav taws xob soldering hlau yog ua los ntawm cov nickel-chromium tsis kam tiv thaiv hlau qhov txhab ntawm lub raj plooj (porcelain tube). Nws kuj yog hais txog 2.5kΩ (20W). Qhov kub ntawm cov hlau soldering feem ntau tuaj yeem ncav cuag li 350OC. Cov cua sov sab hauv soldering hlau muaj cov yam ntxwv ntawm cov cua kub ceev, lub teeb yuag, tsis muaj zog noj, me me thiab siab thermal efficiency, yog li nws tau siv dav.
Tom qab cov hlau nplaum txuas nrog lub hwj chim, nws tsis kub lossis tsis kub dhau. Xyuas seb qhov hluav taws xob hluav taws xob qis dua AC210V (qhov voltage ib txwm yuav tsum yog AC220V). Tsis tshua muaj hluav taws xob yuav ua rau tsis txaus cua sov thiab nyuaj rau soldering. Lub taub hau hlau yog oxidized los yog qhov txuas ntawm lub hauv paus kawg ntawm lub taub hau ntawm cov hlau thiab cov phab ntsa sab hauv ntawm lub raj sab nraud yog oxidized. Yog vim li cas vim li cas cov kab nruab nrab raug them yog tias nyob rau hauv peb-theem plaub-xaim fais fab mov, cov kab nruab nrab yog hauv av thiab muaj peev xwm zoo ib yam li lub ntiaj teb. Yog tias lub teeb neon ci ntsa iab thaum kuaj nrog lub ntsuas hluav taws xob ntsuas hluav taws xob, nws qhia tau tias cov kab nruab nrab raug them (muaj qhov sib txawv ntawm cov kab nruab nrab thiab lub ntiaj teb). Ib qho qhib Circuit Court nyob rau hauv nruab nrab kab, nce nyob rau hauv lub grounding kuj ntawm lub nruab nrab kab, ib tug qhib Circuit Court nyob rau hauv lub hauv av down conductor, los yog ib tug grounded theem kab yuav ua rau lub nruab nrab kab yuav electrified.
