Hauv PCBA tsim, cov txheej txheem tswj hwm hluav taws xob yog ib qho tseem ceeb hauv kev ua kom muaj kev ruaj ntseg, kev siv hluav taws xob thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Hauv qab no yog qee cov ntsiab lus ntawm qhov system-theem lub zog tswj cov tswv yim:
1. Lub zog topology tsim
Switching fais fab mov
Xaiv lub tshuab hluav taws xob hloov hluav taws xob zoo, xws li hloov hom hluav taws xob (SMPS), kom txo tau lub zog siv hluav taws xob thiab tsim hluav taws xob.
Power Topology Optimization
Xaiv qhov tsim nyog lub hwj chim topology, xws li boost, phaw, step-up los yog flyback topology, raws li lub zog yuav tsum tau thiab input voltage ntau yam ntawm cov cuab yeej.
Multi-power supply design
Rau cov khoom siv loj, xav txog kev tsim khoom siv hluav taws xob ntau los txhim kho redundancy thiab kev ntseeg tau.
2. Kev Tswj Hluav Taws Xob Kev Sib Txuas Hluav Taws Xob (PMIC)
Xaiv qhov tsim nyog PMIC
Xaiv IC tswj fais fab sib xyaw ua ke kom yooj yim tsim thiab txhim kho kev ua haujlwm.
Optimization ntawm lub zog rails
Siv cov programmable PMICs tso cai rau kev hloov pauv ntawm qhov hluav taws xob thiab tam sim no rau cov hluav taws xob sib txawv.
3. Cov tswv yim txuag hluav taws xob
Pw tsaug zog hom
Tsim cov cuab yeej los txhawb ntau hom kev pw tsaug zog kom txo tau lub zog siv thaum tsis ua haujlwm.
Load Sensing
Siv cov txheej txheem kev ntsuas kev ntsuas kom tau txais kev kho qhov voltage thiab zaus ntawm cov khoom siv hluav taws xob raws li qhov xav tau ntawm kev thauj khoom.
Dynamic Voltage thiab zaus hloov kho
Siv Dynamic Voltage and Frequency Adjustment (DVFS) lub tswv yim los txo cov kev siv hluav taws xob los ntawm kev txo cov hwj huam hluav taws xob thiab zaus raws li qhov xav tau.
4. Fais fab mov overheating thiab tiv thaiv txhaum
Kev tswj cua sov
Siv cov ntsuas cua sov los saib xyuas cov ntsuas kub thiab ntsuas kev tiv thaiv kom tsis txhob muaj cua sov, xws li txo lub zog los yog ua kom muaj cua sov.
Kev tiv thaiv txhaum
Siv cov khoom siv hluav taws xob tshaj tam sim no, dhau-voltage, thiab luv luv-circuit tiv thaiv kom tsis txhob muaj hluav taws xob puas lossis puas tsuaj.
5. Fais fab kab lim thiab kev tswj qhov hluav taws xob
Cov lim
Siv cov lim fais fab kom txo cov suab nrov thiab cuam tshuam ntawm cov kab hluav taws xob.
Voltage regulators
Siv cov hluav taws xob tswj hluav taws xob ntawm cov hluav taws xob tseem ceeb los xyuas kom muaj kev ruaj ntseg voltage.
6. Lub zog rov qab thiab rov siv dua
Lub zog rov qab los
Xav txog cov cuab yeej siv hluav taws xob zoo xws li cov hnub ci vaj huam sib luag lossis cov khoom siv hluav taws xob thermoelectric kom txo cov roj teeb siv thiab ua kom muaj kev ruaj ntseg.
7. Kev tswj roj teeb
Kev xaiv roj teeb
Xaiv yam tsim nyog thiab muaj peev xwm ntawm cov roj teeb kom tau raws li lub zog ntawm cov khoom siv.
Kev soj ntsuam roj teeb
Ua raws li kev soj ntsuam thiab kev tswj xyuas lub roj teeb kom tsis txhob muaj kev tso tawm ntau dhau lossis tshaj tawm thiab txhim kho roj teeb lub neej.
Charge tswj
Siv cov hluav taws xob tswj hluav taws xob kom nyab xeeb thiab tswj cov roj teeb.
Xav txog cov txheej txheem tswj hwm hluav taws xob theem ua ke no tuaj yeem pab tsim lub zog txuag hluav taws xob, muaj txiaj ntsig zoo, thiab txhim khu kev qha PCBAs uas ua tau raws li cov khoom siv ua tau zoo thiab txuas ntxiv lawv lub neej. Nyob rau tib lub sijhawm, kev txiav txim siab txog kev ruaj ntseg, xws li kev siv hluav taws xob rov qab thiab rov siv dua, tuaj yeem pab txo qis kev vam khom thiab txo qhov cuam tshuam ib puag ncig ntawm cov khoom siv hluav taws xob pov tseg.
