Hauv kev lag luam aerospace, txhua qhov yuam kev me tuaj yeem ua rau muaj kev puas tsuaj loj, yog li ntawd, kev ntseeg siab ntawm cov khoom siv hluav taws xob yog xav tau heev. Raws li ib feem tseem ceeb ntawm aerospace electronic systems, kev ua tau zoo ntawm kev ntseeg siab boards ncaj qha cuam tshuam rau kev nyab xeeb ntawm kev ya davhlau thiab lub hom phiaj ua tiav lossis tsis ua tiav.
Ib puag ncig aerospace yog qhov nyuaj heev. Thaum ya hauv huab cua, lub dav hlau yuav tsum tiv taus kev co hnyav, kev hloov pauv ntawm huab cua siab thiab kub. Siv lub dav hlau neeg nrog caij ua piv txwv, qhov kub sab nraud ntawm qhov siab tshaj plaws tuaj yeem ncav cuag qhov siab tshaj 50 degrees Celsius, thaum qhov kub ntawm lub cav tuaj yeem ncav cuag ntau pua degrees Celsius. Nyob rau hauv qhov chaw, satellites thiab lwm yam spacecraft ntsib hnyav tej yam kev mob xws li nqus tsev vacuum, cosmic rays, thiab alternating kub thiab tsis kub. Piv txwv li, thaum lub satellite nyob rau sab hnub tuaj, qhov kub tuaj yeem nce mus txog 100 degrees Celsius, tab sis thaum nws nkag mus rau sab ntxoov ntxoo, nws yuav poob qis mus rau ntau tshaj 100 degrees Celsius. Nyob rau hauv ib puag ncig zoo li no, cov rooj sib tham muaj kev ntseeg siab yuav tsum ua kom muaj kev ruaj ntseg ntawm cov tshuab hluav taws xob.
Txhawm rau hloov mus rau cov xwm txheej no, kev xaiv cov khoom siv rau kev ntseeg siab boards yog nruj heev. Cov ntaub ntawv ua tau zoo xws li polyimide feem ntau yog siv los ua substrates. Polyimide muaj qhov ua tau zoo heev - qhov kub thiab txias thiab tuaj yeem tswj xyuas lub cev thiab hluav taws xob ruaj khov nyob rau hauv qhov chaw kub siab -. Nws cov iav hloov pauv kub feem ntau yog nyob nruab nrab ntawm 250℃-350 degree, uas tuaj yeem tiv thaiv substrate deformation cuam tshuam rau kev ua haujlwm ntawm qhov kub thiab txias. Nyob rau tib lub sijhawm, nws qhov qis- qhov kub thiab txias kuj tseem zoo heev, nws yuav tsis ua rau qhov kub thiab txias ib puag ncig thiab tseem tuaj yeem tuav lub zog zoo txhua yam. Ntxiv mus, polyimide muaj kev ua haujlwm zoo rwb thaiv tsev, uas tuaj yeem tiv thaiv Circuit Court luv Circuit Court thiab xyuas kom ruaj khov teeb liab kis tau tus mob.
Nyob rau hauv cov nqe lus ntawm kev tsim, lub siab ntseeg board txais lub tswv yim ntawm redundancy tsim. Piv txwv li, rau qhov tseem ceeb circuits, ntau txoj hauv kev hauv Circuit Court nrog tib lub luag haujlwm yuav raug tsim. Thaum lub Circuit Court tsis ua haujlwm, lwm cov circuits tuaj yeem ua haujlwm tam sim ntawd thiab xyuas kom tsis muaj kev cuam tshuam ntawm lub kaw lus. Hauv kev tswj hwm ntawm satellites, ntau yam redundancy feem ntau teeb tsa hauv circuits rau cov haujlwm tseem ceeb xws li kev tswj tus cwj pwm. Tsis tas li ntawd, kev tsim cov kab hluav taws xob tau ua tib zoo ua kom zoo los ntawm kev npaj cov kab layout kom tsim nyog, txo cov teeb liab cuam tshuam, thiab txhim kho qhov tseeb ntawm cov teeb liab kis tau tus mob. Los ntawm kev siv ntau-txheej txheej thaiv cov thev naus laus zis, qhov chaw xaim hluav taws xob tau nce ntxiv thaum siv hauv av thiab cov txheej txheem hluav taws xob rau kev tiv thaiv, txo qhov cuam tshuam ntawm electromagnetic cuam tshuam ntawm cov teeb liab.
Cov pawg ntseeg siab ntseeg tau ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntau lub tshuab aerospace. Nyob rau hauv lub davhlau tswj system, nws ua kom muaj kev sib kis tau zoo thiab ua tiav ntawm kev tswj hwm lub davhlau, uas cuam tshuam rau kev hloov pauv ntawm lub dav hlau tus cwj pwm ntawm lub davhlau thiab kev nyab xeeb tsaws. Nyob rau hauv satellite kev sib txuas lus systems, kom ntseeg tau ruaj khov kis tau tus mob ntawm cov ntaub ntawv nyob rau hauv complex chaw electromagnetic ib puag ncig thiab ua kom tiav kev sib txuas lus txhim khu kev qha ntawm satellites thiab av chaw nres tsheb. Nyob rau hauv cov txheej txheem navigation ntawm qhov chaw sojntsuam, lub rooj tsavxwm muaj kev ntseeg siab kom ntseeg tau tias qhov kev sojntsuam tuaj yeem tau txais thiab ua tiav cov cim taw qhia hauv qhov chaw nyob deb ntawm lub hnub qub, thiab ya raws li lub orbit predetermined.
Txhawm rau kom ntseeg tau qhov zoo ntawm cov rooj tsav xwm muaj kev ntseeg siab, kev lag luam aerospace tau tsim kom muaj kev tswj hwm nruj. Pib los ntawm kev yuav khoom ntawm cov khoom siv raw, kev sim nruj yog ua rau txhua pawg ntawm cov ntaub ntawv kom ntseeg tau tias ua raws li cov qauv. Kev saib xyuas lub sijhawm tiag tiag thiab kev tshuaj xyuas zoo yog ua tiav rau txhua txoj haujlwm hauv cov txheej txheem tsim khoom. Tom qab cov khoom tiav lawm, yuav tsum tau ua ib qho kev simulation ib puag ncig zoo, xws li kev ntsuas kub thiab qis qis, kev ntsuas kev vibration, kuaj hluav taws xob, thiab lwm yam. Hauv kev ntsuas kub thiab qis qis, simulate qhov kub thiab txias ntau yam uas cov khoom yuav tau ntsib thoob plaws hauv nws lub neej, ua ntau txhiab lossis ntau lub voj voog kev sim, thiab kuaj seb cov khoom puas tuaj yeem ua haujlwm ib txwm nyob ntawm qhov kub thiab txias. Tsuas yog lub rooj tsavxwm muaj kev ntseeg siab uas dhau txhua qhov kev xeem tuaj yeem nkag mus rau hauv cov khoom siv aerospace.
