1.3. Kev Tswj Thermal: Cov teeb meem cua sov xws li cov cua sov hauv cheeb tsam thiab cov cua kub tsis sib xws tuaj yeem cuam tshuam cov teeb liab kev ncaj ncees.Cov txheej txheem tswj xyuas thermal kom zoo, suav nrog cov thermal dissipation kom zoo thiab kev taug qab taug qab, yog qhov tseem ceeb rau kev tswj xyuas qhov ua tau zoo.
1.4. Mechanical stress: dabtsi yog khoov thiab dabtsi yog khoov tuaj yeem ua rau muaj kev ntxhov siab ntawm cov khoom siv hluav taws xob tsis zoo. Qhov kev ntxhov siab no tuaj yeem ua rau cov kab tawg, hloov pauv impedance, thiab teeb liab cuam tshuam.Ua tib zoo xav txog kev khoov lub vojvoog, khoov thaj chaw khoov, thiab qhov chaw tso khoom tuaj yeem txo cov teeb meem no.
2. Daim ntawv qhia ib kauj ruam los ntawm kev ua kom ntseeg tau cov teeb liab kev ncaj ncees
Tsim kom nruj-flex Circuit Court boards nrog zoo heev teeb liab kev ncaj ncees yuav tsum tau ua raws li cov lus qhia thiab cov kauj ruam. Cia peb delve rau hauv txhua cov lus qhia kom nkag siab zoo dua.
2.1. Txhais cov kev txwv tsim thiab cov kev xav tau: Pib los ntawm kev txheeb xyuas qhov yuav tsum tau ua, suav nrog cov khoom siv hluav taws xob, tshuab, thiab kev sib dhos.Kev nkag siab txog cov kev txwv no txij thaum pib tuaj yeem pab coj tus txheej txheem tsim.
2.2. Siv cov cuab yeej software rau simulation tsom xam: Siv electromagnetic simulators, teeb liab kev ntsuam xyuas kev ncaj ncees platforms thiab lwm yam software cuab yeej los simulate kev ua tau zoo ntawm lub Circuit Court board.Tshawb xyuas qhov tseem ceeb xws li impedance, crosstalk thiab kev xav kom paub txog cov teeb meem uas muaj peev xwm thiab ua kom tsim nyog hloov kho.
2.3. Plan stacking: Tsim kom muaj qhov zoo tshaj plaws txheej txheej txheej tsim kom muaj kev sib koom ua ke nruj thiab hloov tau yooj yim.Nco ntsoov xaiv cov ntaub ntawv tsim nyog rau txhua txheej kom ua tau raws li qhov yuav tsum tau ua thiab kev ntseeg tau. Xav txog kev tswj impedance, teeb liab kev ncaj ncees, thiab txhua yam kev ruaj ntseg thaum npaj stackup.
