PCBA ua ntau lawm, yog ib qho ntawm cov kauj ruam tseem ceeb heev yuav ua rau muaj kev cuam tshuam weld, thiab muaj peev xwm txawm tias yog vuam tsis zoo, thiab tuaj yeem suav tias yog PCBA vuam nyob rau hauv cov kev tshwm sim tsis txaus ntseeg.
Weld tsis zoo nyob rau hauv cov txheej txheem vuam vim tias tsis raug lossis tus neeg tsis ua haujlwm ntawm lub rooj tsavxwm yog tsawg dua, ua rau muaj kev sib cuag tsis zoo rau peb hu ua Virtual Welding; Qhov chaw vuam vuam virtual yog qhov zoo sib xws yog vim: Ua ntej, lub sijhawm vuam, tsis tau siv lub sijhawm vuam, ua rau lub sijhawm vuam plaub, ua rau lub sijhawm vuam ua kom ntev dhau los lossis ntev dhau; Thib ob, teeb meem flux, tej zaum yuav yog flux, cov flux yuav luv heev lossis ntev heev, cov flux yuav yog cov flux yuav yog cov flux. Cov teeb meem ntsws, tej zaum yuav tsis txaus ntawm flux, lossis txo qis; Thib peb, cov solding hlau taub hau kub yog qhov tsis zoo, qhov ntsuas ntawm cov teeb meem hluav taws xob, qhov zoo tshaj ntawm cov vuam cov teeb meem hauv cov yam ntxwv tsis zoo.
