Yuav ua li cas siv thiab tswj qhov ntxeev ntawm cov hlau soldering:
(1) Cov laj thawj tseem ceeb yog vim li cas lub taub hau hlau tsis lo rau tin yog cov ntsiab lus hauv qab no. Thov zam lawv kom ntau li ntau tau:
(1) Qhov kub yog siab dhau, thiab nws yooj yim rau oxidize lub tin-dipped nto thaum nws tshaj 400 degree.
(2) Tsis yog txhua qhov chaw tinned yog tinned thaum siv. www.dgjs123.com
(3) Tsis tshua muaj flux thaum vuam; los yog siv active flux yuav ua rau saum npoo oxidize sai; dej-soluble flux yog corrosive ntawm qhov kub thiab txias thiab yuav ua puas lub taub hau ntawm cov hlau.
(4) Daim txhuam cev siv los so lub taub hau hlau muaj cov sulfur ntau dhau, qhuav dhau los yog qias neeg heev.
(5) Sib cuag nrog cov khoom organic xws li yas; lubricating roj los yog lwm yam compounds.
(6) Tin tsis huv lossis cov ntsiab lus tin tsawg dhau.
(2) Kev ceev faj thiab kev saib xyuas txoj hauv kev thaum siv lub taub hau soldering:
(1) Ua ntej lub hwj chim ntawm lub taub hau hlau soldering txhua hnub, tshem tawm cov oxides, av los yog flux ntawm lub taub hau soldering; thiab tshem tawm cov impurities los ntawm lub cev cua sov kom tiv thaiv lub taub hau ntawm lub taub hau los ntawm kev daig nrog lub cev cua sov lossis lub tes tsho. Nco ntsoov kaw lub taub hau ntawm lub taub hau kom paub tseeb tias nws nyob hauv qhov chaw.
(2) Thaum siv, ua ntej teem qhov kub ntawm ib ncig ntawm 200 degree rau preheating, thiab ces teem rau 300 degree thaum kub nce mus txog 300 degree. Thaum ncav cuag 300 degree, tin yuav tsum tau ntxiv rau lub tinned ib feem ntawm lub hauv ntej kawg ntawm lub soldering hlau taub nyob rau hauv lub sij hawm, thiab nws yuav stabilize rau 3 ~ 5 feeb, sim seb qhov kub thiab txias yog tus qauv, thiab ces teem rau qhov yuav tsum tau. kev khiav hauj lwm kub.
(3) Thaum welding, tsis txhob siv lub taub hau hlau los xaiv lossis nyem cov khoom uas tau welded, thiab tsis txhob siv kev sib txhuam los vuam. Qhov no yuav tsis pab cov thermal conduction thiab tej zaum yuav ua rau lub soldering hlau taub.
(4) Tsis txhob siv cov khoom ntxhib los txhuam cov hlau nplaum.
(5) Tsis txhob siv flux uas muaj chlorine lossis acid.
(6) Tsis txhob ntxiv ib qho kev sib xyaw rau hauv qhov chaw tin-dipped.
(7) Thaum tsis siv lub sijhawm ntev, txo qhov kub kom qis dua 200 degree, thiab ntxiv cov tin los tiv thaiv cov hlau nplaum. Tsis txhob so; tsuas yog so ntawm daim txhuam cev ntub dej thaum vuam, thiab rov smear lub taub nrog cov tin tshiab. qhia.
(8) Tom qab ua tiav cov haujlwm rau ib hnub, thaum tsis siv vuam, so lub taub hau ntawm lub taub hau kom huv si thiab rov nthuav tawm cov tin tshiab rau ntawm lub taub hau, muab tso rau ntawm cov hlau soldering thiab tua lub hwj chim.
(9) Yog hais tias lub tin-dip nto tau oxidized thiab tsis tuaj yeem tinned, los yog oxide zaj duab xis tau tig dub vim flux thiab tsis tuaj yeem tshem tawm nrog daim txhuam cev, koj tuaj yeem maj mam so nrog 600-800 grit sandpaper, thiab ces qhwv nws nrog tin hlau uas muaj flux. Nyob rau hauv lub wiped tin nto, sov nws kom txog thaum lub tin contacts thiab melts, ces ntxiv tin dua.
