Ua ntej tshaj plaws, koj yuav tsum tau txais cov cuab yeej tsim nyog thiab cov ntaub ntawv. Ua ntej, koj xav tau lub zog hlau zoo nkauj. Hluav Taws Xob - tsawg kawg 100 watts. Zoo dua, siv cov hlau soldering tshaj qhov qhib hluav taws. Nws muaj qhov loj thiab ua kom qhov kub uas xav tau ntev. Xws li soldering qhov muag tsis tshua muaj hnub no, tab sis yog tias koj muaj ib daim ntawm tooj liab ntawm qhov hnyav haum, txuas nrog lub xov hlau rau nws, koj tuaj yeem ua koj tus kheej ib ntus hlau soldering.

Thib ob - koj xav tau ham, piv txwv li cov qauv tin. Thiab qhov thiaj li hu ua flux. Fluxes yog cov ntaub ntawv uas siv los muab cov hlua khi cov hlau thaum txhawm thiab vuam hlau. Hloov chaw ntawm rosin tsoos, nws yog qhov zoo dua los siv etched hydrochloric acid - zinc chloride (ZnCl2). Koj tuaj yeem txais zinc chloride koj tus kheej. Txhawm rau ua qhov no, poob rau 3-4 "ntsiav tshuaj" ntawm zinc lossis ntau dua rau hauv lub raj mis nrog diluted 1: 1 hydrochloric acid kom txog thaum lawv nres yaj. Hauv cov ntawv zoo ib yam, zinc muab rau tsev kawm lub chaw soj nstuam loj. Koj tseem tuaj yeem siv daim ntawm cov roj teeb ntawm kev siv. Nws raug nquahu los ua qhov haujlwm tau piav qhia hauv huab cua huv. Koj tuaj yeem siv borax raws li flux, muaj yav tas los calcined kom nws tsis ua npuas ncauj thaum soldering.

Npaj ua txoj haujlwm tseem ceeb thiab lub luag haujlwm tseem ceeb. Lub tank, ntawm chav kawm, yuav tsum khoob, rinsed thiab qhuav. Peb ua tib zoo tiv thaiv qhov chaw ntawm xau nrog av nplaum thiab degrease nws. Qhov zoo ntawm koj kev ua haujlwm yuav ncaj qha nyob ntawm qhov raug thiab raug ntawm koj cov kev ua.
