Yuav ua li cas siv soldering hlau taub hau revival paste thiab dab tsi ceev faj
Lub taub hau hlau tau oxidized tom qab lub sijhawm luv luv. Lub oxidized soldering hlau ntsis tsis yooj yim rau soldering Cheebtsam, yog li nws yuav tsum tau hloov. Tam sim no muaj ib tug soldering hlau tip resurrection paste, uas yog yooj yim thiab economical, thiab lub soldering hlau taub muaj lub neej tshiab. Ua tau zoo tshem tawm oxide txheej ntawm vuam taub. Thiab tinned lub taub dua kom ua tiav lub hom phiaj ntawm kev rov tsim dua tshiab ntawm lub ntsis. Nws tuaj yeem rov kho txhua yam ntawm cov lus qhia hlau uas tau hlawv dub vim oxidation.
Yuav ua li cas siv soldering hlau taub hau txhawb siab cream:
1. Kev ua haujlwm rov tsim dua yuav tsum tau ua thaum qhov kub ntawm qhov vuam taub yog 300 degree ~ 360 degree.
2. Cia lub taub hau ntawm cov hlau nplaum nplaum tawm tsam cov nplaum uas sawv rov los dua thiab tos ob peb feeb.
3. Ntxuav lub taub hau nrog daim txhuam cev los yog tooj liab.
4. Coated nrog ib txheej tshiab tin, lub taub hau ntawm cov hlau soldering tuaj yeem ua kom huv li tshiab.
Yog tias cov nyhuv rov tsim dua tsis pom tseeb tom qab ib qho kev ua haujlwm, cov kauj ruam tuaj yeem rov ua dua 3-4 zaug kom txog thaum cov nyhuv xav tau tiav, thiab tom qab ntawd txheej txheej tin tshiab tuaj yeem raug plated.
Cov kev ceev faj
Feem ntau siv daim txhuam cev hlau los so lub hau ntawm cov hlau soldering, vim tias cov ntaub so huv heev, ua rau cov oxidation ncaj qha ntawm cov tin txheej, uas yog ib qho yooj yim ua rau lub hau ntawm cov hlau soldering kom kub tuag (tsis yog hais txog. lub tin). Nyob rau hauv rooj plaub no, txawm tias qhov kub thiab txias tau nce, qhov kub tsis kub txaus. Tin, ces raws li txoj kev siv saum toj no los daws.
Thaum lub taub hau regenerated abrasive tseem nyob rau ntawm lub taub hau rau soldering, lub abrasive adheres rau lub Circuit Court board, uas yuav ua rau corrosion thiab puas rau lub rooj tsav xwm Circuit Court. Thov tshem tawm tag nrho cov abrasive ntawm lub taub hau ua ntej soldering.
Thaum cov hlau taub hau kub hnyiab dub thiab oxidizes thiab tsis lo rau tin, tsis txhob siv cov ntaub ntawv rau saum npoo ntawm cov hlau taub hau. Cov txheej txheem ntawm cov hlau nplaum yog nyias heev. Kev siv cov ntaub ntawv tuaj yeem yooj yim ua rau cov hlau nplaum tawg tag nrho. Nrog rau kev kho cov hlau nplaum tom qab muab tshuaj txhuam, koj tsuas yog yuav tsum tau nruab qhov siv cov hlau nplaum rau ntawm cov hlau soldering, tig lub zog kom sov, thiab thaum kub nce mus txog qhov kub ntawm koj li niaj zaus soldering kub, dip lub taub hau rau hauv kev kho. tus neeg sawv cev, thiab ces tam sim ntawd tin lub taub nrog tin hlau, reciprocating Tsuas yog ob peb zaug.
Solder paste yog tsim rau soldering rau ntawm qhov chaw du, xws li ob lub hlau hlau nrog qhov chaw du, hlau soldering, haum rau tag nrho cov khoom siv sab nraud (nco ntsoov ntxuav nws) thiab tsis haum rau BGA soldering vim nws tsis muaj nplaum!
