Cov teeb meem tsim khoom ntawm tuab tooj liab PCB feem ntau suav nrog cov hauv qab no:
1. Kev xaiv cov khoom siv
Thick copper PCB yuav tsum tau siv cov ntaub ntawv uas muaj siab conductivity thiab thermal conductivity, xws li tooj liab, tooj dag, thiab lwm yam. Cov ntaub ntawv no yog kim thiab nyuaj rau txheej txheem, yog li nws yuav tsum tau xaiv cov ntaub ntawv tsim nyog kom tau raws li qhov yuav tsum tau ua ntawm cov khoom.
2. Cov txheej txheem tsim khoom
Kev tsim cov txheej txheem ntawm cov phaj tooj liab tuab PCBs yog qhov nyuaj dua li PCBs zoo tib yam, yuav tsum muaj ntau yam txheej txheem xws li txiav, drilling, electroplating, etching, thiab lwm yam. kuj tseem tswj cov kev txwv ntawm txhua txoj kev los xyuas kom meej qhov zoo thiab ruaj khov ntawm cov khoom.
3. Kev kho cua sov
Thick tooj liab PCB xav tau kev kho cua sov kom tshem tawm cov kev ntxhov siab sab hauv, txhim kho cov khoom siv hluav taws xob thiab hluav taws xob. Thaum lub sij hawm kho cua sov txheej txheem, nws yog ib qho tsim nyog los tswj qhov tsis xws li qhov kub thiab txias, lub sij hawm, thiab txoj kev ua kom txias kom zoo thiab ruaj khov ntawm cov khoom.
4. Vuam
Qhov nyuaj vuam ntawm tuab tooj liab PCB yog qhov siab, thiab cov khoom siv vuam tsim nyog thiab cov txheej txheem yuav tsum tau siv los xyuas kom meej vuam zoo thiab kev ntseeg tau. Lub caij no, kev saib xyuas yuav tsum tau them nyiaj rau kev tiv thaiv qhov tshwm sim ntawm vuam tsis xws luag thaum lub vuam txheej txheem.
5. Kev ntsuam xyuas kev ntseeg siab
Thick tooj liab PCB yuav tsum muaj kev ntseeg siab nruj, xws li kev ntsuas qhov ntsuas hluav taws xob, ntsuas hluav taws xob tiv thaiv, ntsuas huab cua tiv thaiv, thiab lwm yam, txhawm rau txheeb xyuas qhov zoo thiab ruaj khov ntawm cov khoom. Cov kev ntsuam xyuas no yuav tsum tau ua nyob rau hauv ib puag ncig sib txawv los simulate qhov kev siv tiag tiag.
Hauv cov ntsiab lus, cov teeb meem tsim khoom ntawm tuab tooj liab PCB feem ntau tsom rau kev xaiv cov khoom siv, kev tsim khoom, kev kho cua sov, vuam, thiab kev ntsuas kev ntseeg siab. Txhawm rau tsim cov phaj tooj liab zoo zoo PCBs, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom tsim nyog thiab cov txheej txheem tsim khoom, tswj cov txheej txheem ntawm txhua tus txheej txheem, thiab ua cov kev ntsuam xyuas nruj.
