Hauv cov tshuab siv dav hlau tsis muaj neeg siv, cov duab kis tau tus mob yog lub luag haujlwm rau kev xa cov duab tiag tiag - lub sijhawm ntes cov duab thiab cov ntaub ntawv video rau hauv av tau txais qhov kawg. Cov duab kis tau tus mob pcb, raws li nws cov khoom siv kho vajtse tseem ceeb, ncaj qha cuam tshuam rau kev ruaj ntseg, kev pom tseeb, thiab kev sib kis ntawm cov teeb liab kis.
Kev xaiv cov khoom haum rau siab - zaus kis tau tus mob
Lub drone duab kis tau tus mob feem ntau ua haujlwm nyob rau hauv siab -ntau zaus band, yog li cov ntaub ntawv pcb yuav tsum muaj kev ua tau zoo heev - zaus. Tsawg poob pawg thawj coj yog qhov zoo dua, nrog rau qhov ruaj khov dielectric tas li thiab qhov poob qis ntau npaum li qhov ua tau kom ua tau zoo txo cov teeb liab attenuation thaum lub sij hawm kis tau tus mob thiab xyuas kom meej kev sib kis ntawm cov duab thiab video ntaub ntawv. Piv txwv li, qee qhov tshwj xeeb siab - zaus boards tuaj yeem tswj xyuas hluav taws xob ruaj khov hauv qhov chaw siab - zaus, muab txoj hauv kev txhim khu kev qha rau cov duab xa tawm. Nyob rau tib lub sijhawm, qhov kub tsis kam ntawm cov ntaub ntawv tsis tuaj yeem tsis quav ntsej. Thaum lub sijhawm ya ntawm drones, cov duab kis tau tus mob tuaj yeem ua kom sov vim muaj kev ua haujlwm tas mus li. Lub rooj tsavxwm nrog lub iav hloov pauv kub tuaj yeem tswj cov qauv kev ruaj ntseg hauv qhov kub thiab txias ib puag ncig thiab zam kev ua haujlwm tsis zoo los ntawm qhov kub thiab txias.
Cov ntsiab lus tseem ceeb rau optimizing teeb liab kis tau tus mob hauv pcb ntau lawm
impedance piv
Lub impedance txuam ntawm pcb nyob rau hauv daim duab kis tau tus mob module yog ib qho tseem ceeb rau qhov zoo ntawm cov teeb liab kis tau tus mob. Vim lub siab zaus ntawm cov duab kis tau tus mob, impedance mismatch tuaj yeem ua rau muaj teeb meem kev xav, ua rau muaj teeb meem xws li duab stuttering thiab distortion. Nyob rau hauv cov txheej txheem tsim khoom, nws yog ib qho tsim nyog yuav tsum tau ua kom raug xam qhov impedance tus nqi ntawm cov kab sib kis raws li kev ua haujlwm zaus thiab cov yam ntxwv ntawm cov duab kis tau tus mob, thiab xyuas kom meej impedance txuam thiab txo cov teeb liab cuam tshuam los ntawm kev tsim cov kev txwv xws li qhov dav, thickness, thiab kev ncua deb ntawm cov av txheej ntawm cov kab sib txuas kom tsim nyog.
Layout thiab kev npaj cov kab ke
Thaum nteg tawm, nws yog ib qho tsim nyog yuav tsum cais qhov siab -frequency signal path los ntawm low-frequency signal path and the power supply part kom tsis txhob muaj kev cuam tshuam. Qhov siab - cov duab xaim hluav taws xob ntau zaus yuav tsum yog luv thiab ncaj li sai tau, txo qhov khoov thiab hla, thiab txo cov teeb liab qeeb thiab cuam tshuam. Nyob rau tib lub sijhawm, kev siv tag nrho cov txheej hauv av muab txoj hauv kev zoo rov qab rau siab - zaus cov cim, txhim kho cov nyhuv tiv thaiv, thiab suppresses electromagnetic cuam tshuam. Rau cov khoom siv hluav taws xob, nws yog ib qho tsim nyog los npaj cov lim capacitors kom tsim nyog los txo qhov cuam tshuam ntawm lub hwj chim mov suab nrov ntawm cov duab xa tawm thiab xyuas kom ruaj khov.
Cov txheej txheem yuav tsum tau ua kom ntseeg tau
High precision manufacturing txheej txheem
The pcb of the image transmission module often has high integration, dense circuits and hole positions, and strict requirements for manufacturing accuracy. Nyob rau hauv cov txheej txheem drilling, nws yog ib qho tsim nyog yuav tsum xyuas kom meej tias qhov pore loj ntawm micropores yog qhov tseeb thiab tsis sib xws, thiab kom ntseeg tau tias muaj kev ruaj ntseg thiab cov teeb liab txuas ntawm cov khoom. Kev tsim cov khoom siv hluav taws xob yuav tsum yog qhov tseeb, thiab cov kab dav thiab qhov sib txawv yuav tsum tau tswj nyob rau hauv ib qho kev ua yuam kev me me kom tsis txhob muaj teeb meem kev sib kis ntawm cov teeb meem tshwm sim los ntawm qhov tsis xws ntawm Circuit Court. Cov txheej txheem lamination yuav tsum ua kom muaj kev sib raug zoo ntawm txhua txheej, kev sib raug zoo ntawm cov txheej txheem siab, thiab tiv thaiv interlayer tev lossis teeb liab crosstalk.
Cov txheej txheem kho deg
Txhawm rau txhim kho cov kev ua tau zoo thiab kev tiv thaiv corrosion ntawm cov duab kis tau tus mob pcb, kev kho deg thev naus laus zis yog qhov tseem ceeb. Cov txheej txheem kub immersion yog ib qho ntawm cov kev xaiv uas feem ntau siv, uas tuaj yeem tsim cov txheej txheem kub thiab ruaj khov rau saum npoo ntawm pcb. Nws tsis tsuas yog muaj kev ntseeg siab ntawm vuam, tab sis kuj tseem tiv thaiv cov tooj liab txheej oxidation, ua kom muaj hluav taws xob ruaj khov thaum siv sijhawm ntev -. Rau qee cov duab kis tau tus mob uas yuav tsum tau tshwj xeeb, lwm txoj kev kho saum npoo xws li cov organic solder npog kev kho mob kuj tseem siv tau los txo cov nqi thaum ua tau raws li cov kev cai vuam.
Cov txheej txheem xeem nruj
Kev ntsuas hluav taws xob ua haujlwm
Ua cov kev ntsuas hluav taws xob ua tau zoo ntawm pcb ntawm cov duab kis tau tus mob, suav nrog kev ntsuas kev ntsuas hluav taws xob, kom ntseeg tau tias txhua qhov kev sib txuas hauv Circuit Court yog qhov qub thiab tsis muaj qhov qhib circuits; Kev ntsuas hluav taws xob tiv thaiv kom tsis txhob muaj teeb meem cuam tshuam los ntawm kev xau ntawm cov circuits. Nyob rau tib lub sijhawm, lub hom phiaj yog txhawm rau ntsuas qhov kev sib kis tau zoo ntawm - cov teeb liab zaus, siv cov cuab yeej tshaj lij los kuaj xyuas qhov tsis xws li teeb liab attenuation thiab theem hloov, thiab xyuas seb lawv puas ua tau raws li qhov yuav tsum tau ua ntawm cov duab xa mus.
Kev ntsuam xyuas kev ntseeg ntawm ib puag ncig
Qhov chaw ua haujlwm ntawm drones yog qhov nyuaj thiab puas tau - hloov pauv, thiab pcb ntawm cov duab xa tawm yuav tsum dhau qhov kev sim ib puag ncig nruj. Kev ntsuas kub siab tuaj yeem txheeb xyuas nws qhov kev ruaj ntseg hauv siab - qhov kub thiab txias ib puag ncig, zam kev ua haujlwm tsis ua haujlwm ntawm drones nyob rau hauv tshav ntuj ncaj qha lossis ua haujlwm ntev; Kev ntsuas kub qis simulates qhov chaw txias kom ntseeg tau tias cov teeb liab kis tau tus mob tsis cuam tshuam rau qhov kub thiab txias. Tsis tas li ntawd, kev ntsuam xyuas kev vibration kuj tseem ceeb rau simulate qhov kev vibration ib puag ncig thaum lub sij hawm drone ya davhlau, txheeb xyuas qhov ruaj khov ntawm pcb qauv thiab kev ntseeg siab ntawm cov khoom siv soldering, thiab tiv thaiv Circuit Court detachment los yog kev sib cuag tsis zoo los ntawm kev co.
Kev txiav txim siab tshwj xeeb rau kev yoog rau drone scenarios
Cov drones tuaj yeem ntsib ntau qhov chaw nyob hauv lub sijhawm ya davhlau, xws li qhov xav tau ntawm cov duab kis tau tus mob pcb kom muaj qee yam dej noo- pov thawj thiab plua plav- pov thawj muaj peev xwm. Nws qhov kev hloov pauv ib puag ncig tuaj yeem txhim kho los ntawm txheej txheej nrog peb cov pov thawj xim thiab lwm txoj hauv kev. Nyob rau tib lub sijhawm, xav txog qhov yuav tsum tau ua ntawm lub teeb yuag ntawm drones, pcbs yuav tsum nyias thiab hnyav li sai tau thaum ua kom muaj kev ua tau zoo. Cov boards nyias yuav tsum tau xaiv thiab cov qauv tsim kom zoo kom txo tau qhov cuam tshuam rau tag nrho qhov hnyav ntawm drones thiab ncua sij hawm ya davhlau.
