Yuav ua li cas solder

Cov lus nug no yuav ua li cas solder, rau qhov niaj hnub tsev craftsmen thiab cov kws kho-tshwj xeeb yog tsis tsim nyog niaj hnub no. Tab sis thaum nws los mus rau nws, nws puv tawm zoo li hais tias dag txog Leo Tolstoy, uas hlub mus ua si qhov balalaika, tiam sis hmoov tsis ua tsis tau.

Txij li thaum lub masters kawm rau yaj lead thiab tin twb tinkers, uas twb koom nyob rau hauv lub soldering hlau teb.

Joined ua ntej soldering stripped thiab degreased nrog roj. Plev rhuab soldering hlau yog dipped nyob rau hauv rosin los yog ammonia. Yog hais tias cov pa luam yeeb ciali tsis muaj zog, nws txhais tau tias soldering hlau yog npaj txhij rau kev siv.

Ntiab rosin soldering ntxeev los ntawm hlau oxides. Refined soldering ntsis yog dipped nyob rau hauv solder (feem ntau yog tin) thiab nyob muaj mus txog rau thaum nws yog them nrog ntawv ci. Qhov no zaj duab xis yog kis tshaj lub saum npoo ntawm lub hlws ris qhov chaw, i.e. "Tin" nws. Ces, nyob lub hlws ris ntawm kis ib thooj ntawm solder uas yog tsim nyog mus cuag lub workpieces.

Yuav ua li cas solder tsis tau siv ib soldering hlau? Nws yog tej zaum yuav siv tshuaj tebchaw uas muaj peev xwm tso "solder" nrog ib qho kev nce rau hauv lawv kub. Qhov no solder muab tshuaj txhuam. Lawv yog cov tseem ceeb rau soldering nyob rau hauv ib tug tej thaj chaw deb qhov chaw. Cov tshuaj txhuam yog thov mus rau lub hlws ris site thiab rhuab.

Tam sim no cia saib yuav ua li cas solder txhuas. Nws tsis yog ib qho yooj yim ua, txij thaum lub tu nto ntawm lub txhuas oxide zaj duab xis yog tsim dua. Kuaj pom ntawm no zaj duab xis thiaj li daim ntawv cog lus lub zog. Yog li ntawd, sai li sai tau tom qab ntxuav lub saum npoo ntawm hlws ris qhov chaw nyob rau ib tug txhuas workpiece nchuav passive flux. Qhov no yuav ua tau ib tug rosin, glycerol thiab ib yam ntawm cov fatty acids.

Aluminium solder yog hwj chim soldering. Yog hais tias kom xaiv flux, lub txhuas yog yooj yim soldered. Nws saum npoo ntawm tinned tooj liab hlau yuav soldered tsis muaj teeb meem.

Muaj lwm txoj kev: tus nto txheej ntawm txhuas trimmed preform yog lubricated rosin, tooj liab hmoov sprinkled. Tom qab lub lag luam no, soldering ntawm qhov chaw yuav nqa tawm nyob rau hauv lub li ib txwm soldering tin.

Tsis li ntawd, ntev dhau los hloov los ntawm cov kav dej ntawm cov hlau tuaj yas khoom. Yuav ua li cas solder yas kav? Nws ua li nws nyuaj heev yog hais tias muaj yog ib tug tsim nyog lub cuab tam rau lawv welding.

Nyob rau cua sov apparatus txuas nozzle yuav tsum tau loj. Lub regulator yog teem lub kub tshaj 2700 Celsius.

Thaum rhuab nozzle nyob rau vuam siv lub tshuab, npaj thiab txiav yuav tsum tau ntev ntawm cov yeeb nkab. Yuav tsum tau muab tshem tawm burrs thiab roughness, thiab ces tus yeeb nkab yog muab tso rau cim sib npaug zos rau ntawm qhov tob ntawm lub haum. Tom qab cua sov rau cov yeeb nkab nkag mus rau hauv haum rau koj ib measured ntev. Lub Vuam chaw yog degreased. Tam sim no yog lub sij hawm ntawm cov cua kub thiab soldering.

Lub rhuab nozzle pov tseg rau ntawm ib sab ntawm lub vuam apparatus yog thawj muab tso rau hauv haum, vim hais tias nws exhibits thicker phab ntsa, uas yuav tsum tau heev cua sov. Lub haum yuav tsum tau nrees zaum saum lub nozzle. Nyob rau lwm cov tes lub vuam siv lub tshuab mus rau lub thib ob nozzle "tso" yas yeeb nkab.

Sov-up lub sij hawm ntawm cov yeeb nkab thiab haum yog teev nyob rau hauv cov lus qhia rau cov vuam siv lub tshuab. Thaum lub sij hawm ntawm cov cua kub ntawm qhov chaw lawv tsis txhob tig, txij li thaum nws muaj peev xwm ua rau yas compression.

Matured cua kub lub sij hawm, ces cov khoom raug muab tshem tawm los ntawm lub nozzles, thiab yog tswvcuab maj mam mus rau hauv cov yeeb nkab haum mus rau ib tug cim ua yav tas los. Ntswj lub chaw ua hauj lwm daim yuav tsis tau.

Tam sim no uas koj paub yuav ua li cas solder yas kav.
