Qhov zoo ntawm MCCBs yog dab tsi?
MCPCBs muaj ntau qhov zoo dua li cov qauv PCBs, suav nrog cov cua kub zoo dua, txhim kho thermal stability, thiab muaj zog txhua yam. Lawv kuj muaj peev xwm txhawb nqa ntau dua tam sim no thiab muab cov rwb thaiv tsev zoo dua thiab tiv thaiv kev cuam tshuam electromagnetic.
Dab tsi yog qhov tsim kev txiav txim siab rau ceramic PCBs?
Tsim cov ceramic PCB yuav tsum tau txiav txim siab tshwj xeeb vim yog cov khoom tshwj xeeb ntawm cov khoom siv ceramic. Thermal expansion coefficients, mechanical zog, thiab kev xav tau ntawm ceramic vias yog txhua yam tseem ceeb tsim los xav txog. Nws yog ib qho tseem ceeb uas yuav tau ua hauj lwm nrog cov chaw tsim tshuaj paus uas muaj kev txawj ntse hauv ceramic PCB tsim thiab kev tsim khoom los xyuas kom meej cov txiaj ntsig zoo tshaj plaws.
Cov ntaub ntawv dab tsi yog siv los ua ceramic PCBs?
Ceramic PCBs feem ntau yog tsim los ntawm alumina (Al2O3) lossis aluminium nitride (AlN) ceramics. Alumina feem ntau yog siv rau nws cov thermal conductivity thiab hluav taws xob rwb thaiv tsev zog, thaum AlN paub txog nws zoo heev thermal conductivity thiab high hluav taws xob rwb thaiv tsev.
Kuv tuaj yeem ua kom kuv lub PCBA zoo li cas?
Txhawm rau kom ntseeg tau tias koj lub PCBA zoo, nws yog ib qho tseem ceeb uas yuav tsum tau ua haujlwm nrog cov chaw tsim khoom lag luam txhim khu kev qha thiab paub txog uas ua raws li cov txheej txheem tswj xyuas nruj. Tsis tas li ntawd, ua tiav kev sim thiab tshuaj xyuas cov khoom tiav tuaj yeem pab txheeb xyuas cov teeb meem lossis qhov tsis xws luag.
Qhov txawv ntawm PCBA thiab PCB yog dab tsi?
PCB yog hais txog lub rooj tsav xwm lub cev uas muaj cov khoom siv hluav taws xob thiab hluav taws xob sib txuas, thaum PCBA hais txog cov khoom tiav tom qab cov khoom siv hluav taws xob tau teeb tsa ntawm PCB.
Yam khoom siv twg tuaj yeem siv hauv PCBA?
Muaj ntau yam khoom siv uas tuaj yeem siv rau hauv PCBA, suav nrog cov khoom siv saum npoo av (SMDs), cov khoom siv los ntawm lub qhov, kev sib xyaw ua ke (ICs), resistors, capacitors, thiab ntau lwm yam.
Lub neej ntev ntawm PCB yog dab tsi?
Lub neej ntev ntawm PCB yog nyob ntawm ntau yam, nrog rau qhov zoo ntawm cov khoom siv, cov khoom siv ib puag ncig uas siv PCB, thiab qhov kev ntxhov siab ntau npaum li cas rau ntawm lub rooj tsavxwm. Txawm li cas los xij, nrog kev tsim thiab tsim khoom tsim nyog, PCB tuaj yeem kav ntev li ob peb xyoos.
Dab tsi yog txheej txheem ntawm kev tsim khoom PCB?
Cov txheej txheem ntawm kev tsim PCB feem ntau suav nrog kev tsim lub voj voog schematic, tsim ib qho kev teeb tsa ntawm lub voj voog, luam tawm cov txheej txheem rau ntawm lub rooj tsavxwm, etching txoj kev tooj liab mus rau lub rooj tsavxwm, drilling qhov rau cov khoom, thiab txuas cov khoom rau lub rooj tsavxwm. Lub rooj tsavxwm raug kuaj xyuas kom ntseeg tau tias nws ua haujlwm raws li qhov xav tau.
Dab tsi yog qhov txiaj ntsig ntawm kev siv PCB?
PCBs muab ntau cov txiaj ntsig zoo dua lwm txoj hauv kev tsim hluav taws xob hluav taws xob, suav nrog txo qhov loj thiab qhov hnyav, nce kev ntseeg tau, thiab yooj yim ntawm kev sib dhos thiab ntau lawm. Tsis tas li ntawd, PCBs tuaj yeem tsim los tsim kom muaj kev sib txuas ntawm cov khoom siv hluav taws xob thiab tuaj yeem ua kom haum rau ntau yam khoom.
Dab tsi yog cov txheej txheem txheej txheej?
Rau kev thov sib txawv, peb tuaj yeem ua qhov sib txawv ntawm qhov sib txawv kom tau raws li cov neeg siv khoom.Sau qhov chaw tiav, qhov zoo tshaj plaws Technology Co, Limited muaj peev xwm ua rau koj cov ntaub ntawv. HAL PCB: huab cua kub leveling (HAL), uas siv Sn los ua nto tiav, nyeem ntxiv... OSP PCB: Organic solderability preservative (OSP), nyeem ntxiv... ENIG PCB: Electroless Nickel / Immersion Kub (ENIG), Immersion kub ntawm ncoo, nyeem ntxiv ... ENEPIG PCB: electroless nickel electroless palladium immersion kub (ENEPIG), nyeem ntxiv
