Puas yog lub tshuab hluav taws xob muaj zog hluav taws xob zoo lossis lub zog qis?
Lub tshuab hluav taws xob tsis muaj, lub zog siab lossis lub zog me me!
Muaj ntau hom hluav taws xob rau hluav taws xob hlau, cov me me yog 15 watts, 20 watts, loj dua yog 200 watts, 300 watts, thiab rab yaj phom-style 500 watts. Thaum ua haujlwm vuam, lub zog ntawm cov hlau yuav tsum tau txiav txim siab raws li cov khoom siv vuam, thiab qee zaum lub zog ntawm cov hluav taws xob tiv tauj hlau yuav tsum raug xaiv raws li lub caij ntuj no (lub caij ntuj no, lub caij ntuj sov). Rau cov khoom siv hluav taws xob, 15 watts txog 20 watts yog qhov zoo. Yog tias koj siv 500 watts, ib zaug cov hlau soldering poob, nws yuav yog qhov dub. Tau kawg, nws tsis zoo.
Txawm hais tias qhov kev xaiv lub zog tsim nyog los yog tsis yog nyob ntawm qhov ua kom yaj thiab ntws ntawm cov solder. Cov txheej txheem no tsis pub dhau peb vib nas this. Yog tias nws ntev dhau lawm, nws yuav ua rau cov khoom siv hluav taws xob puas, yog tias nws luv dhau, qhov vuam yuav tsis txhim khu kev qha, thiab cov pob qij txha yuav tsis du.
Feem ntau, soldering hlau nrog me me ko taw xws li resistors, capacitors, transistors, thiab cov blocks sib xyaw yuav tsum tau siv nrog 20-watt soldering hlau. Nws yog tsim nyog siv 35 watts mus rau 40 watts thaum vuam cov dab dej kub, transformers, shielding npog thiab lwm yam loj-ko taw, los yog grounding loj cheeb tsam tooj liab-clad daim hlau. Yog li ntawd, raws li cov khoom siv vuam, lub zog ntawm cov hlau soldering yuav tsum raug xaiv kom raug. Tsis muaj lub zog siab lossis lub zog qis.
Taw qhia rau lub hauv paus ntsiab lus ntawm hluav taws xob soldering hlau
False soldering txhais tau hais tias tsuas yog ib qho me me ntawm cov tin yog welded ntawm qhov sib koom ua ke, ua rau muaj kev sib cuag tsis zoo thiab cuam tshuam rau thiab tawm. False welding txhais tau hais tias nws zoo li welded rau saum npoo, tab sis nws tsis yog welded. 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 tib si ntawm cov xwm txheej no tsuas yog zam tau nrog kev siv dav dav, ceev faj kev siv vuam. Thaum soldering circuit boards, nco ntsoov tswj lub sijhawm kom zoo. Yog tias nws ntev dhau lawm, lub rooj tsav xwm Circuit Court yuav raug hlawv, lossis daim ntawv tooj liab yuav poob. Thaum tshem cov khoom los ntawm lub rooj tsav xwm hauv Circuit Court, lo lub hau ntawm cov hluav taws xob soldering hlau 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 qee qhov kev sib raug zoo nrog lub ntim, cov duab thiab qhov ntev ntawm cov hlau taub hau. Thaum lub ntim ntawm cov hlau taub hau yog qhov loj, lub sijhawm khaws cia ntev dua. Tsis tas li ntawd, txhawm rau ua kom tau raws li qhov xav tau ntawm cov khoom siv sib txawv, cov duab ntawm cov hlau taub hau yog txawv, thiab cov khoom siv yog lub khob hliav qab, chisel, ncig bevel thiab lwm yam.
Siv lub ohm ntau yam ntawm multimeter los ntsuas seb puas muaj qhov qhib Circuit Court lossis luv luv ntawm ob qho kawg ntawm lub ntsaws, thiab tom qab ntawd siv Rx1000 lossis Rx10000 ntau yam 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 sab hauv hom hluav taws xob soldering hlau yog ua los ntawm cov nickel-chromium tsis kam tiv thaiv hlau qhov txhab ntawm lub plooj (porcelain raj). Nws kuj yog hais txog 2.5kΩ (20W), thiab qhov kub ntawm cov hlau soldering feem ntau ncav cuag li 350OC. Vim hais tias cov cua sov sab hauv hom hluav taws xob soldering hlau muaj cov yam ntxwv ntawm cov cua kub ceev, lub teeb yuag, tsis muaj zog noj, me me thiab siab thermal efficiency, nws tau siv dav. Tom qab cov hlau nplaum txuas nrog lub hwj chim, yog tias nws tsis kub lossis tsis kub dhau, xyuas seb qhov hluav taws xob hluav taws xob puas qis dua AC210V (qhov voltage ib txwm yuav tsum yog AC220V). Yog tias qhov hluav taws xob tsawg dhau lawm, nws yuav ua rau muaj cua sov tsis txaus thiab nyuaj rau kev 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 rau kev siv hluav taws xob ntawm cov kab nruab nrab 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 tus cwj mem ntsuas, nws qhia tau tias tus lej xoom raug them (muaj qhov sib txawv ntawm xoom kab thiab lub ntiaj teb). Qhov qhib Circuit Court ntawm cov kab nruab nrab, qhov nce ntawm cov av tsis kam ntawm cov kab nruab nrab lossis qhib Circuit Court ntawm cov khoom siv hauv av thiab cov av ntawm cov theem kab yuav tag nrho ua rau cov kab nruab nrab raug them.
