Yuav ua li cas khiav lub vuam scraping, plating thiab kuaj cov hluav taws xob soldering hlau
chais plaub
Scraping txhais tau tias ntxuav qhov saum npoo ntawm cov khoom hlau yuav tsum tau welded ua ntej vuam. Koj tuaj yeem siv rab riam, seem hlau sawb, thiab lwm yam los txhuam tawm (lossis zom nws nrog cov ntawv xuab zeb zoo lossis tshem tawm nrog cov ntxhib ntxhib) txheej oxide, roj stain los yog cov xim pleev xim rau ntawm qhov chaw vuam. kom txog thaum cov hlau tshiab raug nthuav tawm. Ua ntej welding lub rooj sib tham hauv tsev, koj kuj yuav tsum tau ua tib zoo txhuam cov tooj liab-clad sab nrog cov ntawv xuab zeb los yog dej xuab zeb. "Scraping" yog ib kauj ruam tseem ceeb los xyuas kom meej vuam zoo, tab sis nws feem ntau tsis quav ntsej los ntawm cov neeg pib tshiab. Yog hais tias lub scraping tsis ua kom zoo, tin plating yuav tsis zoo thiab vuam yuav tsis yooj yim. Nws yuav tsum raug sau tseg tias qee cov khoom siv lead ua tau plated nrog nyiaj, kub lossis tin enameled. Tsuav lawv tsis oxidized los yog tev tawm, tsis tas yuav khawb lawv. Yog tias muaj av nyob rau saum npoo, nws tuaj yeem raug tshem tawm nrog cov tawv tawv tawv. Qhov kev xaiv ntawm cov ntaub ntawv tuab yog qhov zoo tshaj plaws rau cov eraser loj siv rau kev kos duab. Qee qhov kub-plated transistor tus pin leads, thiab lwm yam, yuav nyuaj rau phaj nrog tin tom qab txheej txheej yog khawb tawm. Tsis muaj teeb meem dab tsi ntawm "scraping" yog siv, yuav tsum tau them nyiaj mloog mus tas li tig cov pins tivthaiv kom ntseeg tau tias thaj chaw ib puag ncig ntawm tus pins huv si.
plating
Plating yog tinning qhov chaw yuav tsum tau welded raws li qhia nyob rau hauv daim duab 4. Tom qab "scraping", lub soldering qhov chaw xws li tivthaiv pins thiab hlau hau yuav tsum tam sim ntawd coated nrog ib tug tsim nyog tus nqi ntawm flux, thiab ib tug nyias txheej ntawm tin yuav tsum tau plated. nrog ib tug soldering hlau los tiv thaiv saum npoo los ntawm oxidized dua thiab txhim kho cov solderability ntawm cov khoom. poj niam deev. Lub plated solder txheej yuav tsum nyias thiab sib xws, yog li tus nqi ntawm cov tin ntawm lub taub hau yuav tsum tsis txhob ntau dhau txhua zaus. Rau cov khoom siv xws li siv lead ua diodes thiab transistors uas ntshai tsam raug hlawv, nco ntsoov siv cov tweezers lossis rab koob-qhov ntswg pliers txhawm rau txhawm rau cov hauv paus hniav ntawm cov hlau lead pins ua ntej los pab dissipate tshav kub, thiab tom qab ntawd ua tin plating. Tin enameling ntawm Cheebtsam yog txheej txheem tseem ceeb hauv kev siv tshuab vuam los tiv thaiv kev phom sij xws li kev sib tsoo tsis tseeb thiab tsis tseeb soldering. Nws yuav tsum tsis txhob sloppy.
Kev ntsuas
Kev ntsuam xyuas yog los tshuaj xyuas cov tin-enameled Cheebtsam kom pom tias muaj kev kub nyhiab, deformations, lap welding (short circuits), thiab lwm yam. Rau cov khoom xws li capacitors, transistors, integrated circuits, thiab lwm yam, ib tug multimeter yuav tsum tau siv los xyuas seb lawv cov khoom puas zoo. Cov khoom uas pom tias yog qhov tsis zoo los yog puas yuav tsum tsis txhob rov siv dua.
