Yuav ua li cas koj kuaj qhov tsis kam ntawm ib qho hluav taws xob soldering hlau?
Hluav taws xob soldering hlau yog cov cuab yeej tseem ceeb rau kev tsim hluav taws xob thiab kev kho hluav taws xob, feem ntau yog siv rau cov khoom siv vuam thiab cov xov hlau. Nws tuaj yeem muab faib ua hluav taws xob hluav taws xob sab hauv hluav taws xob thiab hluav taws xob sab nraud hluav taws xob soldering hlau raws li cov qauv siv tshuab. Raws li kev ua haujlwm, nws tuaj yeem muab faib ua cov hlau tsis-suction soldering thiab suction soldering hlau. Raws li kev siv sib txawv, nws tuaj yeem muab faib ua ntau lub zog soldering hlau thiab qis zog soldering hlau.
Kev ntsuam xyuas hluav taws xob hluav taws xob muaj peb ntu: kev ntsuas kev tiv thaiv hauv av (lub xeev txias / kub), qhov ntsuas hluav taws xob to, thiab kev ntsuas tam sim no.
1. Grounding resistance test ntawm hluav taws xob soldering hlau hauv lub xeev txias:
Thaum tsis muaj hwj chim, txuas ib kawg ntawm lub multimeter sojntsuam mus rau hauv av davhlau ya nyob twg ntawm lub hwj chim plug thiab lwm kawg mus rau lub ntsis ntawm lub soldering hlau mus kuaj cov ntaub ntawv;
2. Kev ntsuam xyuas hauv av ntawm hluav taws xob soldering hlau nyob rau hauv lub xeev cua sov:
Txuas lub hwj chim, tig rau ntawm cov hlau soldering, thiab txuas ib kawg ntawm lub multimeter sojntsuam mus rau hauv av davhlau ya nyob twg ntawm lub qhov (socket), thaum lwm kawg hu rau lub rooj tsavxwm kuaj uas yog nyob rau hauv kev sib cuag nrog lub soldering hlau. Ntsuas qhov tshwm sim;
3. Kev ntsuas hluav taws xob hluav taws xob thiab kev ntsuas hluav taws xob tam sim no ntawm cov hluav taws xob soldering hlau zoo ib yam li cov qauv ntsuas kev tiv thaiv. Nws yuav tsum tau muab sau tseg tias lub multimeter yuav tsum tau hloov lub zog los yog kho qhov chaw ntawm lub multimeter sojntsuam hlau thaum ntsuas tam sim no.
Yuav ua li cas xaiv ib tug hluav taws xob soldering hlau?
(1) Thaum welding integrated circuits, transistors, thiab cov khoom uas ua rau thermal puas, xav txog kev siv 20W sab hauv cua sov lossis 25W sab nraud cua sov soldering hlau.
(2) Thaum welding thicker xov hlau los yog coaxial cables, xav txog siv 50W sab hauv rhuab los yog 45-75W externally rhuab soldering hlau.
(3) Thaum vuam cov khoom loj dua, xws li cov hlau chassis grounding pads, yuav tsum siv lub tshuab hluav taws xob uas muaj zog tshaj 100W.
(4) Cov duab ntawm lub taub hau taub hau yuav tsum yoog raws li qhov yuav tsum tau ua ntawm qhov chaw welded thiab qhov sib dhos ntom ntom ntawm cov khoom.
Cias muab tso, lub hwj chim thiab hom hluav taws xob soldering hlau yuav tsum raug xaiv tsim nyog raws li cov khoom siv vuam. Yog hais tias lub workpiece yuav tsum tau welded loj, lub hwj chim ntawm hluav taws xob soldering hlau siv yuav tsum siab dua. Yog tias lub zog qis, qhov vuam kub qis dhau lawm, lub vuam yaj maj mam maj mam, cov flux tsis yooj yim rau evaporate, cov pob qij txha tsis du thiab ruaj khov, uas yuav ua rau muaj qhov tsis zoo ntawm qhov zoo thiab vuam lub zog, thiab txawm tias qhov sib txawv ntawm qhov sib txawv. solder tsis tuaj yeem yaj, ua rau vuam ua tsis tau. Txawm li cas los xij, lub zog ntawm cov hlau soldering yuav tsum tsis txhob siab dhau. Yog tias nws siab dhau lawm, nws yuav hloov cov cua kub ntau dhau mus rau qhov chaw welded, ua rau cov pob qij txha ntawm cov khoom sib txuas ua rau overheat, uas yuav ua rau cov khoom puas tsuaj, ua rau cov ntawv ci tooj liab ntawm cov ntawv luam tawm hauv Circuit Court poob, thiab solder ntws nrawm dhau ntawm qhov chaw vuam, uas tswj tsis tau.
