3. Kev kho yuav nyuaj
Yog tias muaj ntau txheej txheej PCB ntsib teeb meem, ces nws yuav nyuaj rau kho.Qee cov khaubncaws sab nraud povtseg yuav tsis raug saib los ntawm sab nraud, ua rau nws nyuaj rau txheeb xyuas qhov ua rau cov khoom siv lossis lub cev puas tsuaj.Ntxiv rau, koj yuav tsum xav txog cov naj npawb ntawm cov khoom sib xyaw ua ke ntawm lub rooj tsavxwm vim nws ua rau kev kho kom yooj yim dua kom tiav.
Qhov txawv: Ib Txheej PCB Vs Ntau Txheej PCB
1. Cov txheej txheem tsim khoom
Ib txheej PCB dhau los ua cov txheej txheem tsim khoom ntev.Feem ntau, nws yuav siv ntau yamCNC machiningcov txheej txheem los tsim lub rooj tsavxwm.Tag nrho cov txheej txheem suav nrog kev txiav-drilling-graphics tso-etching-solder daim npog qhov ncauj thiab luam ntawv.
Tom qab ntawd, nws dhau los ntawm kev kho saum npoo ua ntej raug kuaj, tshuaj xyuas, thiab ntim rau kev xa khoom.
Lub caij no, multilayer PCBs yog tsim los ntawm cov txheej txheem tshwj xeeb.Nws koom nrog overlaying prepreg thiab foundational txheej txheej ua ke los ntawm kev kub siab thiab kub.Qhov no ua kom ntseeg tau tias huab cua yuav tsis nkag mus rau ntawm txhua txheej.Tsis tas li ntawd, nws txhais tau hais tias resin yuav npog cov conductors thiab cov nplaum uas ruaj txhua txheej ua ke melts thiab kho kom raug.
2. Khoom siv
Ib txheej thiab ntau txheej PCBs yog tsim los siv hlau, FR-4, CEM, Teflon, thiab polyimide cov ntaub ntawv.Txawm li ntawd los, tooj liab yog qhov kev xaiv tshaj plaws.
3. Tus nqi
Zuag qhia tag nrho, ib txheej PCB yog tus nqi tsawg dua li ntau txheej PCB.Qhov no feem ntau yog vim cov ntaub ntawv siv, lub sijhawm tsim khoom, thiab kev txawj ntse.Lwm yam yuav cuam tshuam rau tus nqi, suav nrog qhov loj me, lamination, lub sijhawm ua haujlwm, thiab lwm yam.
4. Daim ntawv thov
Feem ntau, ib txheej PCBs yog siv rau cov khoom siv yooj yim, thaum ntau txheej PCBs muaj ntau dua rau cov thev naus laus zis, xws li smartphones.
Kev txiav txim siab seb koj xav tau ib txheej lossis ntau txheej PCBs
Nws yuav pab tau yog tias koj txiav txim siab seb puas yuav tsum muaj ntau txheej lossis ib txheej luam tawm Circuit Board rau koj qhov project.Tom qab ntawd, xav txog hom phiaj xwm twg koj muaj thiab qhov zoo tshaj plaws haum yog dab tsi.Nov yog tsib lo lus nug uas koj yuav tsum nug koj tus kheej:
