Dab tsi yog qhov ua tau rau cov pob qij txha tsis zoo, thiab puas muaj kev daws teeb meem zoo?
(1) Cov pob khoom raug tsim, thiab cov tin tsis tuaj yeem kis mus rau tag nrho lub ncoo?
Qhov kub ntawm cov hlau soldering yog tsawg dhau, los yog lub hau ntawm cov hlau soldering me me dhau; lub ncoo yog oxidized.
(2) Thaum cov hlau raug tshem tawm, lub taub hau yog tsim?
Cov hlau soldering tsis kub txaus, flux tsis yaj, thiab cov kauj ruam ua haujlwm. Yog hais tias qhov kub ntawm cov hlau taub hau yog siab dhau, cov flux yuav evaporate thiab lub sij hawm soldering yuav ntev dhau lawm.
(3) Lub tin nto tsis du thiab wrinkled?
Lub soldering hlau kub yog siab dhau lawm thiab lub sij hawm soldering yog ntev heev.
(4) Loj rosin kis cheeb tsam?
Lub taub hau ntawm cov hlau soldering yog tuav nruj heev.
(5) Cov hlaws dai?
Lub tin hlau yog ntxiv ncaj qha los ntawm qhov kawg ntawm cov hlau soldering, ntau ntau cov tin yog ntxiv, lub ntsis ntawm cov hlau soldering yog oxidized, thiab cov hlau soldering raug ntaus.
(6) PCB sib cais txheej?
Qhov kub ntawm cov hlau soldering yog siab dhau lawm, thiab qhov kawg ntawm cov hlau soldering hits lub rooj tsavxwm.
(7) Dub rosin?
Kub siab heev.
