PCB ntim tau txais kev saib xyuas ntxiv. Kev ntim khoom zoo PCB tuaj yeem ua kom muaj kev ua tau zoo thiab ruaj khov ntawm cov khoom siv hluav taws xob, thaum tseem txhim kho kev tsim khoom thiab txo cov nqi tsim khoom. Yog li, peb yuav tsum ua li cas nrog PCB ntim?
1, Xaiv txoj kev ntim khoom tsim nyog
Muaj ob hom kev ntim khoom PCB: phau ntawv ntim thiab tshuab / automated ntim. Kev ntim cov ntawv ntim yog tsim rau cov xwm txheej me me, thiab cov khoom siv tuaj yeem ua manually soldered rau PCBs raws li xav tau; Tshuab / automated ntim yog tsim rau ntau lawm thiab tuaj yeem txiav cov khoom siv rau PCBs los ntawm cov tshuab. Kev xaiv cov txheej txheem ntim yuav tsum yog raws li qhov xav tau tiag tiag thiab cov xwm txheej tsim khoom.
2, Npaj cov cuab yeej thiab cov khoom tsim nyog
Thaum ua PCB ntim, nws yog ib qho tsim nyog yuav tsum tau npaj cov cuab yeej tsim nyog thiab cov khoom siv, xws li PCB boards, cov khoom siv, cov xov hlau, cov chaw nres tsheb, cov tshuaj coatings, thiab lwm yam. Yog tias cov khoom loj yuav tsum tau ua, cov khoom siv tau zoo thiab cov khoom siv xws li tsis siv neeg. vuam tshuab, steel mesh tshuab luam ntawv, thiab lwm yam yuav tsum tau.
3, Txheeb xyuas cov ntaub ntawv tiv thaiv cov ntaub ntawv phau ntawv
Ua ntej PCB ntim, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam cov khoom siv thiab qhia meej txog lawv qhov ntsuas, qhov ntev, tus pin txoj haujlwm, thiab lwm yam ntaub ntawv. Tsuas yog nyob rau hauv txoj kev no tuaj yeem kho PCB tsim thiab ntim khoom.
4, Ua PCB tsim
Thaum tsim ib lub PCB, qhov ntev, tus pin txoj hauj lwm, drilling txoj hauj lwm, thiab lwm yam tsis ntawm lub PCB pob yuav tsum tau txiav txim raws li cov ntaub ntawv nyob rau hauv cov ntaub ntawv tivthaiv phau ntawv. Nyob rau tib lub sijhawm, cov yam ntxwv xws li cov tuab, cov txheej txheem, thiab cov txheej txheem ntim khoom ntawm PCB pawg thawj coj yuav tsum tau txiav txim siab.
5, Ua PCB ntim
Thaum ua cov khoom ntim PCB, cov khoom yuav tsum tau soldered mus rau lub rooj tsavxwm PCB ua ntej, tom qab ntawd npog nrog cov tshuaj coatings, thiab thaum kawg soldered rau cov khoom los ntawm immersion los yog immersion soldering.
