Kev ruaj ntseg ntawm lub tsheb tsis muaj neeg tsav dav hlau (UAV) lub rooj tsav xwm tsav dav hlau yog 90% txiav txim siab los ntawm qhov zoo ntawm cov ntawv luam tawm Circuit Board (PCB). Davhlau maub los PCBs yuav tsum tiv taus qhov siab ntawm kev co thiab xyuas kom meej lub teeb liab; txawm tias me ntsis tsis xws luag tuaj yeem ua rau lub dav hlau poob. Niaj hnub no, raws li kev ntsuas tiag tiag thiab cov qauv kev lag luam, kuv yuav nthuav qhia qhov qeb duas ntawm cov tswj lub davhlau PCBs thiab cov ntsiab lus tseem ceeb xaiv.
Basic Knowledge: Cov Lus Qhia Tseem Ceeb ntawm Flight Controller PCBs
Lub davhlau tswj PCB, lub hauv paus tseem ceeb ntawm lub davhlau tswj system, ncaj qha cuam tshuam rau lub dav hlau cov lus teb ceev thiab kev ntseeg tau. Raws li kev tshawb fawb luam tawm nyob rau hauv 42nd qhov teeb meem ntawm phau ntawv journal *Electronic Cheebtsam thiab cov ntaub ntawv* nyob rau hauv 2023, cov nram qab no qhia yuav tsum tau hais txog rau lub davhlau tswj PCBs:
Hais txog cov txheej txheem txheej txheem, kev sib tw davhlau PCBs muaj 4 mus rau 8 txheej. Ntau- txheej txheej tsim tau zoo cais cov teeb liab cuam tshuam.
Hais txog kev xaiv cov khoom siv hauv pawg thawj coj: Rau siab - cov ntawv thov zaus, cov khoom siv uas tsis tshua muaj dielectric tsis tu ncua, xws li FR-4, lossis txawm tias qib siab Rogers cov ntaub ntawv.
Raws li qhov yuav tsum tau muaj tam sim no, tooj liab thickness yog tsim nyog, yuav tsum tau mus txog 1oz mus rau 2oz. Qhov no yog txhawm rau txo qhov tsis kam thiab kub tsim.
Cov txheej txheem kho deg muaj xws li tin plating, immersion kub, thiab OSP (Organic Solder Surface Mount). Immersion kub yog haum rau siab - daim ntawv thov kev ntseeg siab.
Hais txog ntawm txoj kab uas hla precision, qhov kam rau ntawm txoj kab uas hla yuav tsum tau tswj nyob rau hauv ± 0.05 hli los tiv thaiv soldering tsis xws luag.
Cov lus pom zoo yuav khoom
Qhov zoo ntawm lub davhlau tswj PCB ncaj qha txiav txim siab txoj sia nyob ntawm lub dav hlau. Yog tias koj ua qhov tseem ceeb tshaj plaws ntawm kev ruaj ntseg thiab kev ua neej ntev, nws qhov siab - cov txheej txheem kev tsim khoom raug thiab Qib 3 cov qauv xa khoom ua rau nws yog qhov kev xaiv zoo tshaj plaws ntawm kev ua lag luam. Nws kuj yog ib qho kev xaiv thaum pob nyiaj siv tsawg, tab sis kev soj ntsuam cov khoom siv tau zoo yog qhov tseem ceeb. Lwm lub npe muaj qhov ua tsis tau zoo hauv cov ntsuas kev ua haujlwm tseem ceeb thiab raug pom zoo tsuas yog rau kev txheeb xyuas tus qauv lossis tsis yog- daim ntawv thov tseem ceeb.
Txawm li cas los xij ntawm cov chaw tsim khoom koj xaiv, nws yog ib qho tseem ceeb kom ntseeg tau tias koj tus qauv tsim tsis haum rau PCB cov chaw tsim khoom tsim thiab thov cov ntaub ntawv xa tawm tshiab los ntawm lawv. Flight controller kev nyab xeeb pib nrog lub PCB txhim khu kev qha.
