2. Kev ntim khoom siab heev thiab kev sib koom ua ke
Cov yam ntxwv me me: Muaj nyob rau hauv cov pob khoom txheem kev lag luam thiab cov qhov ntau thiab tsawg tshwj xeeb rau cov qauv tsim uas txwv qhov chaw.
Kev sib xws ntawm qhov chaw: Sib xws nrog cov khoom siv xaiv thiab tso tsis siv neeg thiab cov txheej txheem reflow soldering, ua rau muaj kev tsim khoom ntau.
Kev tsim kho ruaj khov: Siv cov khoom siv ceramic, ferrite, lossis cov khoom sib xyaw ua ke nrog cov khoom tiav (Ni/Sn, Au) uas tsim nyog rau cov xwm txheej ib puag ncig hnyav.
ESD thiab kev tiv thaiv thermal: Cov yam ntxwv tiv thaiv uas suav nrog tuaj yeem tiv taus ESD cov xwm txheej (txog li 2kV HBM) thiab qhov kub thiab txias ua haujlwm.
3. Txhim kho kev ntseeg siab thiab kev ua kom zoo dua rau daim ntawv thov
Kev ua haujlwm siab ntawm kev rho tawm: Muab kev rho tawm ntawm qhov chaw nres nkoj mus rau qhov chaw nres nkoj feem ntau tshaj 20 dB kom tiv thaiv kev sib txuas ntawm cov teeb liab tsis xav tau.
Muaj peev xwm tswj hwm fais fab: Txhawb nqa cov theem fais fab los ntawm milliwatts mus rau ntau lub watts nyob ntawm qhov loj me ntawm pob thiab tsim.
Kev kho kom zoo rau tus qauv: Muaj nyob rau hauv cov kev teeb tsa uas tau kho kom zoo rau cov ntawv thov tshwj xeeb (Wi-Fi, cellular, Bluetooth, thiab lwm yam) nrog cov yam ntxwv S-parameters.
