Vim li cas Circuit Boards yuav tsum tau pleev xim?

Sab pem hauv ntej thiab sab nraub qaum ntawm pcb Circuit Court yog cov txheej tooj liab. Hauv kev tsim thiab tsim khoom ntawm pcb circuits, seb cov txheej tooj liab yog tsim los ntawm tus nqi sib txawv los yog los ntawm ob qho - lej ntxiv thiab rho tawm txoj kev, qhov kawg tshwm sim yog du thiab txij nkawm- dawb nto . Txawm hais tias lub cev muaj zog ntawm tooj liab tsis zoo li aluminium, hlau, magnesium, thiab lwm yam, nyob rau hauv qhov chaw ntawm dej khov, ntshiab tooj liab thiab oxygen yog yooj yim heev rau oxidized; xav txog lub hav zoov ntawm co2 thiab dej vapor nyob rau hauv cov huab cua, tag nrho cov tooj liab nto Ib tug redox cov tshuaj tiv thaiv tshwm sim sai heev thaum sib cuag nrog cov pa. Xav tias qhov tuab ntawm cov txheej tooj liab nyob rau hauv pcb Circuit Court yog nyias dhau lawm, cov tooj liab tom qab cua oxidation yuav dhau los ua hluav taws xob quasi - lub xeev ruaj khov, uas yuav ua rau cov khoom siv hluav taws xob zoo heev ntawm txhua qhov pcb circuits.

Txhawm rau kom thaiv cov tooj liab oxidation zoo dua, kom zoo dua cais cov hluav taws xob vuam ib feem ntawm pcb Circuit Court los ntawm qhov tsis yog - hluav taws xob vuam ib feem ntawm pcb Circuit Court thaum fais fab vuam, thiab kom zoo dua tswj qhov chaw ntawm lub pcb Circuit Court, lub technical engineers tau tsim thiab tsim qee yam tshwj xeeb Architectural Coatings. Xws li architectural txheej tuaj yeem txhuam tau yooj yim rau ntawm qhov chaw ntawm pcb Circuit Court, uas ua rau muaj kev tiv thaiv txheej tuab uas yuav tsum nyias nyias, thiab thaiv kev sib cuag ntawm tooj liab thiab roj. Cov txheej txheej ntawm plating no yog hu ua tooj liab, thiab cov khoom siv raw yog siv lub npog ntsej muag.
