Vim li cas lub tin ib txwm ua raws li lub taub hau soldering thaum siv hluav taws xob soldering hlau?
Yog tias lub taub hau vuam ntawm cov hluav taws xob soldering hlau tsis noj tin, lub hau ntawm cov hlau soldering yuav sai sai no oxidized vim qhov kub thiab txias. Feem ntau hu ua hlawv kom tuag! Tom qab oxidation, lub ntsis ntawm cov hlau soldering tig dub, thiab nws yog ib qho nyuaj rau yaj thiab solder ua ntej! Koj yuav pom tias qhov kub ntawm cov hlau qub yog siab heev, thiab txawm tias cov khib nyiab me me tuaj yeem ua rau tawg! Tab sis lub solder tsis tuaj yeem kub! Yog li ntawd lub taub hau hlau yuav tsum khaws ib txheej ntawm cov tin zaj duab xis los tiv thaiv cov hlau taub hau ntawm oxidation. Thaum vuam, cov cua sov tuaj yeem hloov mus rau lub sijhawm kom ntseeg tau tias qhov vuam zoo.
Thiab koj hais tias yuav ib txwm muaj ntau tshaj solder ntawm lub ntsis ntawm cov hlau soldering, uas kuj yog ib qho tshwm sim. Thaum soldering, lub melted solder yeej ib txwm ntws los ntawm qhov chaw uas tsis muaj kub mus rau qhov chaw uas muaj kub. Yog li peb tuaj yeem siv qhov zoo ntawm qhov no. Thaum kho lub rooj tsav xwm hauv Circuit Court thiab tshem tawm qhov chaw, siv cov hlau nplaum los nqus ib feem ntawm cov hlua ntawm tus pins qub. Tau kawg, nws yuav zoo dua los siv lub tin absorber thiab tin absorber kom tshem tawm cov solder.
Tom qab cov hlau taub hau absorbs ntau tshaj solder, peb tuaj yeem siv cov txheej txheem ntawm kev co cov hlau soldering maj mam, thiab siv inertia los co tawm cov tshaj solder ntawm lub taub hau soldering. Feem ntau, dipped lub taub hau ntawm rosin, thiab tom qab ntawd co koj lub dab teg sai sai, pov lub solder rau hauv lub thawv rosin. Thiab thaum peb xav noj tin rau tus thawj pins, los yog tin rau cov xov hlau, los yog solder cov thawj nyob rau hauv lub Circuit Court board, peb muaj peev xwm siv lub taub hau ntawm soldering hlau noj solder nyob rau hauv lub rosin, thiab ncaj qha noj tin los yog solder rau. thawj tus pins los ua rau nws. vuam thiab lwm yam.
Thaum siv cov hlau soldering, xyuam xim rau cov ntsiab lus hauv qab no:
(1) Txheeb xyuas cov kab hluav taws xob thiab rwb thaiv tsev. Ua ntej siv cov hlau soldering, xyuas seb cov xaim hluav taws xob puas yog thiab seb qhov rwb thaiv tsev ntawm lub plhaub thiab lub rhaub puas zoo, kom tsis txhob poob lossis hluav taws xob poob.
(2) Tin rau ntawm qhov kawg ntawm cov hlau soldering. Tus tshiab soldering hlau taub yuav tsum tau tinned ua ntej siv. Ua ntej, siv cov ntawv xuab zeb zoo los yog cov ntaub ntawv zoo kom tshem tawm cov oxide ntawm lub taub hau ntawm lub taub hau, thiab tom qab ntawd ua kom sov nrog hluav taws xob. Thaum cov hlau taub hau tig los ntawm cov ntshav liab mus rau ntshav xim av, thov ib txheej ntawm rosin, thiab maj mam txhuam cov hlau nplaum rau ntawm nws, yog li ntawd lub hau ntawm cov hlau taub hau yog coated nrog ib txheej nyias ntawm solder. Lub solder yuav tsum tau thov tusyees. Yog tias qee qhov tsis noj tin, nws txhais tau tias qhov chaw tsis huv. Lub sijhawm no, nws yuav tsum tau rov tinned raws li cov txheej txheem saum toj no.
Tom qab siv lub sij hawm ntev ntawm cov hlau taub hau, qhov qub tiaj tus duab yuav hloov. Lub sij hawm no, tus pin yuav tsum tau unscrewed, lub soldering hlau taub yuav tsum tau muab tshem tawm, thiab tus thawj zoo yuav tsum tau refiled nrog ib daim ntawv, thiab tinned.
(3) Kev tswj qhov kub thiab txias. Qhov kub ntawm cov hlau taub hau yuav tsum tsim nyog. Thaum kub siab dhau lawm, nws yooj yim rau oxidize thiab tig dub, uas cuam tshuam rau tinning; Yog tias qhov kub thiab txias qis dhau, nws tsis tsim nyog rau lub melting ntawm solder thiab cuam tshuam rau vuam zoo. Kho qhov kub ntawm cov hlau taub hau tuaj yeem ua tiav los ntawm kev hloov qhov ntev nws protrudes. Qhov ntev ntawm qhov ntev ntawm cov hlau taub hau tawm, qhov kub thiab txias; conversely, qhov luv ntawm sticking tawm ntev, qhov siab dua qhov kub.
(4) Vuam txoj kev. Hom hluav taws xob soldering hlau yuav tsum raug xaiv raws li qhov loj ntawm qhov vuam, thiab lub zog hluav taws xob hluav taws xob yuav tsum tau siv thaum lub tshuab ua haujlwm loj. Ua ntej vuam, siv cov ntawv xuab zeb los yog cov ntaub ntawv hlau los txhuam qhov vuam ntawm qhov chaw ua haujlwm thiab nthuav tawm cov hlau huv. Tom qab dipping lub preheated soldering hlau taub nrog rosin (cov kauj ruam no yuav raug tshem tawm yog hais tias lub solder hlau muaj rosin nyob rau hauv), tshem tawm nws. Nyob rau hauv txoj hauj lwm vuam, ntxiv solder hlau rau welding kom khov kho (lub solder yuav tsum tsis txhob ntau dhau). Rau cov workpieces loj, vuam nto tuaj yeem ua kom sov ua ntej, thiab yog tias qhov vuam tsis zoo nyob rau ib zaug, nws tuaj yeem welded ob peb zaug. Yog vim li cas rau cov tsis zoo soldering yog feem ntau yog hais tias lub soldering nto tsis huv los yog lub soldering kub yog tsawg. Lub sijhawm no, yuav tsum tau siv lub zog hluav taws xob ntau dua.
(5) Ua tib zoo saib xyuas kev nyab xeeb. Thaum soldering, hluav taws xob soldering hlau yuav tsum tau ua tib zoo saib xyuas, thiab tsis txhob kov yuav tsum zam. Yog hais tias muaj ntau dhau ntawm lub taub ntawm cov hlau soldering, nws yuav tsum tau muab tshem tawm maj mam thiab tsis muab pov tseg. Thaum tsis siv ib ntus, nws yuav tsum tau muab tso rau ntawm ib lub taub hau hlau, lossis muab tso rau hauv qhov chaw uas tsis muaj cua sov. Tsis txhob muab tso rau hauv random kom tsis txhob scalding lwm yam khoom. Thaum tsis siv sijhawm ntev, lub zog yuav tsum raug txiav tawm kom tsis txhob muaj oxidation ntau dhau ntawm lub taub hau hlau. Feem ntau, cov hluav taws xob soldering hlau yuav tsum tau muab tso rau hauv qhov chaw qhuav kom tsis txhob ntxov ntxov corrosion ntawm cov cua sov ua haujlwm hlau.
