Hobaneng ha thepa ea PCB e le ea bohlokoa ho li-UAV
Di-drone tse fapaneng di na le mesebetsi e fapaneng—empa kaofela di itshetlehile hodima mokokotlo o tsitsitseng wa PCB ho netefatsa botsitso ba lets'oao, ho hanyetsa mocheso, le mabaka a bobebe a sebopeho. Substrate e fosahetseng e ka lebisa ho:
- Tieho ea lets'oao liphepelong tsa FPV tsa nako ea sebele
- Tšitiso ea RF ho li-module tsa radar
- Ho sotha tlas'a meroalo e phahameng ea mocheso
- Ho khomarela ho fokolang le ho qhaqha ha leqhubu sefofaneng se nang le ho thothomela ho hoholo
Papiso ea Lintho: Rogers vs PTFE vs FR4-TG170 vs Polyimide
| Thepa | Matla a Dielectric | Tg (Phetoho ea Khalase °C) | Tahlehelo ea Letšoao | Boima ba 'mele | Litšenyehelo | Linyeoe tsa Tšebeliso |
|---|---|---|---|---|---|---|
| Rogers 4350B | E babatsehang | 280°C | Tlase Haholo | E itekanetseng | Holimo | RF e phahameng, li-drone tsa radar |
| PTFE | E phahameng | >300°C | E tlase haholo | Tlase | Holimo Haholo | Li-UAV tsa sesole, li-module tse utloang EMI |
| FR4-TG170 | Ho lokile | 170°C | E itekanetseng | E itekanetseng | E theko e tlase | Li-drone tsa merero e akaretsang, PCB ea taolo ea sefofane |
| Polyimide | E babatsehang | 260°C | Tlase | Tlase Haholo | Mahareng | Li-PCB tse Flex, meaho ea li-drone tse ka menwang |
Hlokomela: Leha Rogers le PTFE di fana ka dibopeho tse ntle tsa RF, FR4-TG170 e ntse e le tekanyo e ntle ka ho fetisisa bakeng sa ho haha tekanyetso, mme polyimide e kgethwa ditshebedisong tse flex/rigid-flex jwalo ka matsoho a UAV a ka menwang.
Na u batla ho fokotsa boima ba 'mele ntle le ho beha matla kotsing? Re boetse re tšehetsa meralo ea PCB e tšehelitsoeng ke aluminium le ea tšepe bakeng sa li-module tsa drone tse bohlokoa haholo mochesong.
Khothaletso e Thehiloeng ho Kopo
- Drone ea FPV: FR4-TG170 kapa Polyimide
- UAV e tsamaisoang ke AI (mohlala, NVIDIA Jetson TX2 e kene): Rogers 4350B
- Drone ea Tšireletso kapa ea Tlhokomelo: PTFE kapa Rogers e nang le tšireletso ea EMI
- Drone e menwang kapa e bobebe: Polyimide (li-stackups tse thata tse flex-rigid)
Keletso ea Litsebi ho tsoa ho Merero ea 'Nete ea UAV
"Ho e 'ngoe ea merero ea rona bakeng sa mofani oa NATO, Rogers 4350B e khethiloe bakeng sa sebopeho sa radar sa drone ea AI. E ntlafalitse haholo karolelano ea lets'oao-lerata libakeng tse telele."
— Moetapele oa Tekheniki oa RichPCBA
"Bakeng sa moreki ea etsang li-drone tsa bareki tse ka menwang, ho fetohela ho polyimide ho fokolitse ho petsoha ha boto le ho eketsa bophelo ba ho flexa ka makhetlo a 4."

Buisana le Baenjiniere ba Rona Pele U Etsa Qeto
Re thusitse bahlahisi ba fetang 150 ba didrone Europe, Bochabela bo Hare, le US ho rala di-PCB tse loketseng morero. Hore na ha o na bonnete ka tahlehelo ya dielectric, di-coefficients tsa mocheso, kapa botsitso ba lamination, re mona ho thusa.
