Ua tau 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.
(3) Puas yog tin nto tsis du los yog wrinkled?
Qhov kub ntawm cov hlau soldering yog siab dhau thiab lub sijhawm vuam ntev dhau lawm.
(4) Puas yog thaj tsam ntawm rosin dispersion loj? Tuav lub taub hau taub hau kom du.
(5) Cov hlaws dai? Ntxiv tin hlau ncaj qha los ntawm lub taub hau soldering, ntxiv ntau cov tin, oxidize lub taub hau, thiab ntaus cov hlau soldering.
(6) PCB delamination? Qhov kub ntawm cov hlau soldering yog siab dhau lawm, thiab lub taub hau ntawm cov hlau soldering hits lub rooj tsavxwm.
(7) Dub rosin? Kub siab heev
Kev txiav txim siab ntawm cov ntsiab lus tsis yog txheej txheem 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 los ntawm cov khoom siv ntau dhau ntawm cov taw, thaum lwm qhov tshwm sim tshwm sim los ntawm kev siv tsis raug ntawm cov tweezers, xyoob sticks, thiab lwm yam los ntawm cov neeg ua haujlwm soj ntsuam, ua rau luv luv ntawm cov 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 soldering los yog ua yuam kev tshwm sim thaum lub sij hawm soldering, cov pins tsis nyob rau hauv lub cheeb tsam solder pad.
(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 kev txhim kho.
(5) Multi tin: Cov ko taw yog tag nrho nrog cov tin thiab tsim ib qho chaw sab nrauv, ua rau qhov
Lub ntsej muag thiab cov ntaub qhwv lub ntsej muag tsis tuaj yeem pom, thiab nws tsis paub meej tias cov khoom thiab cov ntaub qhwv tau 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.
