Qhov thib ob xaiv yog ntau ruaj ntseg, vim nws tsis ua rau xeb lub Rooj Tswjhwm Saib. Tus thawj hom tshuaj txhuam yuav ntxuav tawm nrog dej, yog li lawv muaj pes tsawg leeg muaj yam uas yuav ua tau teeb meem xov tooj cua kiag li lawm.

Nws yuav tsum tau muab sau tseg tias cov tshuaj yeeb dej caw yuav raug manufactured lead-raws li los yog tsis. Qhov thib ob hom tshuaj txhuam yog environmentally kev nyab xeeb.

Yuav ua li cas mus xaiv thiab cia cov khoom?

Nyob rau hauv thiaj li yuav tau hauj lwm ua zoo thiab meej, koj yuav tsum mus yuav qhov "txoj cai" solder muab tshuaj txhuam. Ua ntej ntawm tag nrho cov, koj yuav tsum xyuam xim rau cov kev yam ntxwv ntawm cov khoom: cov av noo thiab cua kub, cia nta.

Cov hais cov ntaub ntawv uas muaj peev xwm poob nws zoo, nyob ntawm seb cov laus. Cov kev xaiv nyob ntawm seb yam ntawm cov nplej zom thiab nws tau. Ntawm cov hoob kawm, ib tug tseem ceeb tshaj yuav yog tus nqi ntawm cov khoom. Solder muab tshuaj txhuam, tus nqi ntawm uas yog hais txog $ 10 rau 50 grams thiab saum toj no, muag xwb nyob rau hauv daim ntawv pov thawj kev muag khoom cov ntsiab lus.

Nrog hais txog qhov cia cov ntaub ntawv, nws yog tsim nyog los muab tso rau hauv lub tub yees nyob qhov twg qhov kub thiab txias tsis sawv saum toj no 4 degrees. Thaum lub sij hawm uas nws siv nyob rau hauv lub chav tsev yuav tsum sov tab sis tsis kub (tsis ntau tshaj 25 ⁰ C). Ya li yuav tsum tsis txhob mus txog 80%. Ua ntej siv, tus tshuaj yuav tsum tau rhuab rau chav tsev kub thiab xwb ces qhib lub can. Tej zaum nws yuav siv sijhawm txog li 6 teev.

Nta ntawm daim ntawv thov cov ntaub ntawv uas

Brazing solder muab tshuaj txhuam nws muaj nws tus kheej nuances. Piv txwv li, qhov chaw uas tus tshuaj yuav tsum muaj ntaub ntawv, yuav tsum muaj kiag li huv si, qhuav thiab defatted. Tus nqi rau qhov ntev ntawm lub chaw ua hauj lwm yuav tsum tau raws li nrees tsau nyob rau hauv ib tug kab rov tav txoj hauj lwm.

Ib qhov chaw uas yuav propaivatsya yuav tsum tau them kom tiav nrog rau cov tshuaj yeeb dej caw. Tom qab hais tias, sim heev precisely muab tso rau lub rooj tsavxwm tag nrho cov tsim nyog paub meej. Tam sim no koj muaj peev xwm npaj mus rau lub cua sov ntawm cov khoom nrog ib tug plaub hau tshuab. Lub dav hlau li yuav tsum tsis txhob yuav muaj zog dhau. Nws kub yuav tsum txog 150 degrees raws li ntev raws li lub tshuaj txhuam suab los ntawm tag nrho cov flux. Tom qab hais tias, lub dav hlau yuav ua tau kub (200-250 ⁰ C).

Tom qab tag nrho cov ua hauj lwm board yuav tsum tau txias thiab ntxuav lub seem ntawm lub substance. Qhov no txoj kev nyob rau hauv lub hom nplej zom.
