Ob peb txheej txheem ntawm luam tawm hauv Circuit Court board Yog raws li nram no:

1. Kev npaj vuam ua ntej: Kev npaj vuam ua ntej suav nrog kev ntxuav vuam txoj haujlwm, kev teeb tsa cov cuab yeej hluav taws xob thiab kev npaj cov khoom siv vuam, kev hloov pauv thiab cov cuab yeej tshwj xeeb. Sab tes laug laug hlau, sab laug tuav hluav taws xob ferrochrome (xaim hluav taws xob kom huv, thiab ua kom lub taub hau vuam tuav qhov vuam xwm txheej txhua lub sijhawm thiab nyob qhov twg).

2, qhov cua sov vuam qhov: yuav tsum tau them sai sai rau cua sov txhua qhov vuam tag nrho, ua kom sov sib npaug.

3, rau hauv cov hluav taws xob: tom qab ua kom sov qhov vuam ib feem yuav tsum tau kub, cov hluav taws xob txhuam cov hlau los ntawm lub qhov rooj rov mus kov qhov vuam.

4, tshem cov electrode: thaum cov electrode melts txaus, tshem tawm cov electrode tam sim ntawd.

5, tshem tawm hluav taws xob vuam: tom qab cov hlau txuas hla cov txheej vuam lossis qhov vuam qhov ntawm qhov chaw vuam, tshem cov hlau hluav taws xob.

Xuas tes ua xaim xaim vuam txuas cov laug cam, PCB Circuit board PCB rau vuam vuam cov kws tshaj lij, feem ntau yog qhov yooj yim, tab sis rau cov uas tsis tau vuam vuam rau, yuav muaj qee qhov nyuaj, tshwj xeeb tshaj yog vuam vuam yog tias ua yuam kev, tom qab ntawd yuav tsum tau muab tshem tawm teeb meem, ntsib qee qhov tsis zoo ntawm PCB PCB pawg thawj coj saib, Qhov tshwm sim ntawm txheej txheej txheej txheej ntog tawm yog qhov loj heev.
