6 Txheej ENIG FR4 Heavy Copper PCB
Hnyav tooj liab PCB yog ib txheej ntawm cov ntawv ci tooj liab sib txuas ntawm iav epoxy substrate ntawm cov ntawv luam tawm Circuit Court.Thaum lub thickness ntawm tiav tooj liab yog ntau tshaj los yog sib npaug rau 2oz, nws yog txhais raws li hnyav tooj liab PCB.hnyav tooj liab PCB muaj qhov zoo tshaj plaws extensibility thiab tsis txwv los ntawm kev ua haujlwm kub.Txawm tias nyob rau hauv huab cua corrosive heev, tooj liab PCB yuav tsim ib tug muaj zog thiab tsis muaj tshuaj lom passivation tiv thaiv txheej.hnyav tooj liab PCB yog dav siv nyob rau hauv ntau yam khoom siv hauv tsev, cov khoom siv high-tech, tub rog, kev kho mob thiab lwm yam khoom siv hluav taws xob.Daim ntawv thov ntawm cov tooj liab hnyav PCB ua rau lub rooj tsav xwm hauv Circuit Court, cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob, muaj lub neej ua haujlwm ntev.Nyob rau tib lub sijhawm, nws yuav pab tau kom yooj yim lub ntim ntawm cov khoom siv hluav taws xob.
Peb Qhov Zoo
Qhov siab tshaj plaws tooj liab thickness ntawm tus qauv yog 8oz, thiab tooj liab thickness yog 6oz nyob rau hauv loj ntau lawm
Qhia cov cuab yeej ua haujlwm siab ntawm PCB kev lag luam txhua xyoo los xyuas kom meej cov txheej txheem PCB zoo heev
Ua haujlwm lean ntau lawm, saib xyuas qhov kev ua tau zoo ntawm kev tsim khoom thiab txhim kho tus nqi xa khoom
Teeb meem hauv kev tsim khoom hnyav tooj liab PCB
1. Nyob rau hauv cov txheej txheem ntawm etching, yog tias etching tsis huv, lub siab yuav tsis ncav cuag tus qauv, uas yuav ua rau luv luv Circuit Court.
2. Thick tooj liab PCB yog ib qho yooj yim rau foaming tus neeg sawv cev nyob rau hauv cov txheej txheem ntawm solder daim npog qhov ncauj number case manufacturing.
3. Cov seem ntawm cov tuab tooj liab PCB yog qhov siab tshaj plaws hauv cov txheej txheem drilling, qhov tuab thiab cov ntsia hlau taub hau yog qhov siab tshaj plaws.
4. Nyob rau hauv cov txheej txheem ntawm nias, nws yog ib qho yooj yim uas yuav tshwm sim teeb meem xws li tsis txaus kua nplaum filling, kua nplaum ntws ntau dhau, tsis sib xws thickness thiab voids.
