Vim li cas cov khoom siv PCB tseem ceeb hauv UAVs
Cov drones sib txawv muaj lub luag haujlwm sib txawv - tab sis txhua tus vam khom rau lub hauv paus PCB ruaj khov kom ntseeg tau tias lub teeb liab muaj kev ruaj khov, tiv taus cua sov, thiab cov yam ntxwv tsis hnyav. Cov substrate tsis raug tuaj yeem ua rau:
- Kev ncua sij hawm ntawm lub teeb liab hauv lub sijhawm tiag tiag FPV pub
- Kev cuam tshuam RF hauv cov modules radar
- Kev khoov thaum muaj kev kub ntxhov siab
- Kev nplaum tsis zoo thiab kev tawg tsis zoo hauv kev ya dav hlau uas muaj kev co siab
Kev Sib Piv Khoom Siv: Rogers vs PTFE vs FR4-TG170 vs Polyimide
| Khoom siv | Lub zog dielectric | Tg (Kev Hloov Iav ° C) | Kev Poob Teeb Liab | Qhov hnyav | Tus nqi | Cov Qauv Siv |
|---|---|---|---|---|---|---|
| Rogers 4350B | Zoo heev | 280°C | Qis heev | Nruab nrab | Siab | Cov drones radar uas muaj zaus siab heev |
| PTFE | Zoo tshaj plaws | >300°C | Qis heev | Qis | Siab heev | Tub Rog UAV, EMI-sensitive modules |
| FR4-TG170 | Zoo | 170°C | Nruab nrab | Nruab nrab | Pheej yig | Cov drones siv dav dav, PCB tswj kev ya dav hlau |
| Polyimide | Zoo heev | 260°C | Qis | Qis heev | Nruab Nrab | Cov PCBs uas yoog tau, cov qauv drone uas muab tais tau |
Lus Cim: Thaum Rogers thiab PTFE muaj cov yam ntxwv RF zoo dua, FR4-TG170 tseem yog qhov sib npaug zoo tshaj plaws rau kev tsim peev nyiaj, thiab polyimide yog qhov nyiam dua hauv cov ntawv thov flex / rigid-flex zoo li caj npab UAV uas tuaj yeem tais tau.
Xav kom txo qhov hnyav yam tsis muaj kev cuam tshuam rau lub zog? Peb kuj txhawb nqa cov qauv PCB uas muaj txhuas thiab hlau rau cov qauv drone uas muaj cua sov thiab tsis kub dhau.
Cov Lus Qhia Raws Li Daim Ntawv Thov
- FPV Drone: FR4-TG170 lossis Polyimide
- AI-Powered UAV (piv txwv li, NVIDIA Jetson TX2 onboard): Rogers 4350B
- Kev Tiv Thaiv lossis Kev Soj Ntsuam Drone: PTFE lossis Rogers nrog EMI shielding
- Lub Drone Uas Muab Tau Los Yog Sib Nqus Tau: Polyimide (flex-rigid stackups)
Cov Lus Qhia Los Ntawm Cov Kws Tshaj Lij Los Ntawm Cov Haujlwm UAV Tiag
"Hauv ib qho ntawm peb cov haujlwm rau NATO tus neeg muab khoom, Rogers 4350B tau raug xaiv rau AI drone radar interface. Nws tau txhim kho qhov sib piv ntawm lub teeb liab thiab suab nrov ntawm qhov ntev."

Tham nrog Peb Cov Engineers Ua Ntej Koj Txiav Txim Siab
Peb tau pab ntau tshaj 150 lub tuam txhab tsim drone hauv Tebchaws Europe, Middle East, thiab Tebchaws Meskas tsim cov PCB stackups uas tsim nyog rau lub hom phiaj. Txawm hais tias koj tsis paub meej txog kev poob dielectric, cov coefficients thermal, lossis kev ruaj khov ntawm lamination, peb nyob ntawm no los pab.
