Soldering lub xov tooj cua sib xyaw rau hauv cov laug cam yog qhov yooj yim dua li txuas cov xov hlau dawb, vim tias lub qhov hauv cov laug cam txig kho qhov zoo sib xws. Txawm hais tias nyob ntawm no, ib yam nkaus thiab, qhov tshwm sim ntawm kev ua haujlwm yuav nyob ntawm kev paub thiab me ntsis ntawm hmoov. Lub voj voog thawj thawj, sib sau ua ke rau ntawm lub khob cij, feem ntau yuav tsis tiav zoo. Tab sis tsis txhob chim siab - dhau sijhawm, qhov zoo ntawm kev sib txuas yuav tsuas loj hlob.
Cov Lus Qhia
Kauj ruam 1
Yog li, lub hom phiaj ntawm kev txhim kho microcircuit ntawm ib pawg yog ua kom zoo sib xws, muaj kev sib txuas zoo. Cov haujlwm no tuaj yeem tawg ua ob peb kauj ruam.
Kauj ruam 2
Thawj kauj ruam yog ib txhij coj cov ham thiab qhov taub ntawm ib tug twb rhuab soldering hlau mus rau qhov chaw uas koj xav tau los tsim kev twb kev txuas. Nco ntsoov tias qhov kawg ntawm cov hlau soldering yuav tsum tau nyob rau hauv kev sib cuag nrog ob tus pin txhawm rau kom ua thiab cov txiag nws tus kheej.
Kauj ruam 3
Tsis txhob hloov txoj haujlwm ntawm kub taub hau soldering kom txog rau thaum hu rau tag nrho thaj chaw yog tusyees them nrog ham. Qhov no tuaj yeem siv sijhawm ntev li ib nrab ntawm ob mus txog lub sijhawm thib ob - lub sijhawm no txaus rau cov cua kub txaus ntawm cov ntsiab lus soldering.
Kauj ruam 4
Tam sim no koj yuav tsum khij voj voos qhov kawg ntawm cov hlau soldering nyob ib ncig ntawm kev tiv tauj yuav raug ua nyob rau hauv ib lub voj voog, tib lub sijhawm txav cov nqov mus rau qhov tsis sib xws. Nyob rau hauv tib txoj kev, siv li ntawm 1 hli ntau dua ntawm cov cam rau lub chaw soldered. Los ntawm lub sijhawm no, cov ntsiab lus soldering yuav yog li kub kub uas, nyob rau hauv qhov kev cuam tshuam ntawm qhov chaw muaj zog ntawm lub cev, tus kav hlau yaj yog tusyees tshaj li cov chaw muag khoom.
Kauj ruam 5
Tam sim no uas koj tau thov txaus tus nqi solder rau lub cheeb tsam soldered, koj tuaj yeem tshem cov xov hlau tawm ntawm qhov chaw ntawd kom ua soldered.
Kauj Ruam 6
Kauj ruam kawg yog kom nrawm nrawm hlau soldering mus deb ntawm qhov chaw mus rau soldered. Lub sijhawm no, thaum lub hedgehog kua solder, them nrog txheej nyias ntawm flux, yuav siv nws daim ntawv kawg, solidifying.
