Txheem rau kev ntsuas qhov zoo ntawm cov pob qij txha hauv hluav taws xob soldering hlau thiab ua rau cov pob qij txha tsis zoo
1. Txheem Tin Point
(1) Cov tin dots tsim ib qho chaw sab hauv.
(2) Tin dots yuav tsum yog puag ncig, du, tsis muaj pinholes lossis rosin stains.
(3) Hlau pins, thiab qhov ntev ntawm tus pins yuav tsum nyob nruab nrab ntawm 1-1.2MM.
(4) Cov tsos ntawm ib feem ko taw qhia zoo flowability ntawm tin.
(5) Tin puag ncig tag nrho cov tin sab sauv thiab ib feem taw.
2. Kev txiav txim siab ntawm cov ntsiab lus uas tsis yog tus qauv tin
(1) False soldering: Zoo li soldered tab sis tsis tiag tiag soldered, feem ntau yog vim qias neeg solder pads thiab pins, los yog tsis txaus soldering flux thiab cua sov lub sij hawm.
(2) luv luv Circuit Court: Ib qho khoom siv nrog taw yog luv luv Circuit Court ntawm lawv vim yog solder ntau dhau, lossis vim kev ua haujlwm tsis raug los ntawm cov neeg soj ntsuam siv cov tweezers, xyoob sticks, thiab lwm yam, ua rau muaj kev sib cuag luv luv ntawm ko taw. Qhov no kuj muaj xws li residual tin slag ua rau luv luv Circuit Court ntawm ko taw.
(3) Kev sib txawv: Vim qhov tsis raug ntawm qhov chaw ntawm lub cuab yeej ua ntej vuam lossis yuam kev tshwm sim thaum lub sij hawm vuam, cov pins tsis nyob hauv thaj tsam ntawm cov ntaub qhwv.
(4) Tsawg tin: Tsawg tin yog hais txog lub ntsiab lus tin yog nyias dhau los npog tag nrho cov ntawv tooj liab ntawm qhov, uas cuam tshuam rau kev sib txuas thiab kho cov nyhuv.
(5) Cov tin ntau dhau: Cov ko taw ntu tau npog tag nrho nrog cov tin thiab ua rau sab nraud, ua rau cov tsos thiab cov ntaub qhwv lub ntsej muag ntawm qhov pom tsis pom, thiab tsis tuaj yeem txiav txim siab seb puas yog qhov thiab cov ntaub qhwv zoo soldered.
(6) Cov khoom tsis raug: Yog tias cov lus qhia tshwj xeeb lossis hom khoom tso tawm tsis ua raws li cov cai ntawm kev ua haujlwm lossis BOM lossis ECN, nws raug suav tias yog qhov tsis raug.
(7) Cov khoom ploj: Qhov chaw uas yuav tsum tau muab tso rau hauv qhov chaw, ua rau muaj qhov sib txawv vim qhov txawv txav.
(8) Tin pob thiab slag: Ntau cov khoom siv solder thiab slag txuas rau saum npoo ntawm PCB board tuaj yeem ua rau me me pin luv Circuit Court.
(9) Polarity thim rov qab: Yog tias qhov tseeb polarity orientation tsis sib haum nrog cov txheej txheem ua, nws suav tias yog qhov yuam kev polarity.
3. Ua rau cov pob qij txha tsis zoo
(1) Ua cov pob tin, tin tsis tuaj yeem kis thoob plaws tag nrho cov ntaub qhwv
Qhov kub ntawm cov hlau soldering yog tsawg dhau, los yog lub taub hau ntawm lub taub hau me me dhau; Solder ncoo oxidation.
(2) Ua ib lub taub hau thaum tshem cov hlau soldering
Lub soldering hlau tsis kub txaus, thiab lub soldering flux tsis melted, uas yuav siv sij hawm los ntawm kauj ruam. Qhov kub ntawm lub taub hau hlau soldering yog siab dhau lawm, cov flux evaporates, thiab lub sijhawm vuam ntev dhau lawm.
