Chifukwa Chake Zinthu za PCB Ndi Zofunika mu UAVs
Ma drone osiyanasiyana ali ndi ntchito zosiyanasiyana—koma onse amadalira msana wokhazikika wa PCB kuti atsimikizire kulimba kwa chizindikiro, kukana kutentha, komanso mawonekedwe opepuka. Choyipa chapansi panthaka chingayambitse:
- Kuchedwa kwa chizindikiro mu ma feed a FPV nthawi yeniyeni
- Kusokoneza kwa RF mu ma module a radar
- Kugwedezeka pansi pa katundu wotentha kwambiri
- Kuphatikizika kofooka ndi kufalikira kwa madera mu ndege yothamanga kwambiri
Kuyerekeza Zinthu: Rogers vs PTFE vs FR4-TG170 vs Polyimide
| Zinthu Zofunika | Mphamvu ya Dielectric | Tg (Kusintha kwa Galasi °C) | Kutayika kwa Chizindikiro | Kulemera | Mtengo | Makesi Ogwiritsira Ntchito |
|---|---|---|---|---|---|---|
| Rogers 4350B | Zabwino kwambiri | 280°C | Zochepa Kwambiri | Wocheperako | Pamwamba | Ma RF apamwamba kwambiri, ma radar drones |
| PTFE | Wapamwamba | >300°C | Zotsika kwambiri | Zochepa | Pamwamba Kwambiri | Ma UAV ankhondo, ma module ozindikira EMI |
| FR4-TG170 | Zabwino | 170°C | Wocheperako | Wocheperako | Zotsika mtengo | Ma drone ogwiritsidwa ntchito nthawi zonse, PCB yowongolera ndege |
| Polyimide | Zabwino kwambiri | 260°C | Zochepa | Zochepa Kwambiri | Pakatikati | Ma PCB osinthasintha, nyumba zoyendetsedwa ndi ma drone |
Zindikirani: Ngakhale kuti Rogers ndi PTFE amapereka mawonekedwe abwino kwambiri a RF, FR4-TG170 ikadali yoyenera kwambiri popanga bajeti, ndipo polyimide imakondedwa mu ntchito zosinthasintha/zolimba monga manja a UAV opindika.
Mukufuna kuchepetsa thupi popanda kuwononga mphamvu? Timathandizanso mapangidwe a PCB okhala ndi aluminiyamu komanso achitsulo kuti mugwiritse ntchito ma drone ofunikira kutentha.
Malangizo Ochokera ku Ntchito
- FPV Drone: FR4-TG170 kapena Polyimide
- UAV Yoyendetsedwa ndi AI (monga, NVIDIA Jetson TX2 yomwe ili mkati): Rogers 4350B
- Drone Yoteteza kapena Yoyang'anira: PTFE kapena Rogers yokhala ndi chitetezo cha EMI
- Drone Yopindika kapena Yopepuka: Polyimide (zomangira zolimba zosinthasintha)
Upangiri wa Akatswiri Ochokera ku Mapulojekiti Enieni a UAV
"Mu imodzi mwa mapulojekiti athu ogulitsa NATO, Rogers 4350B idasankhidwa kuti igwiritsidwe ntchito pa radar ya AI drone. Idasintha kwambiri chiŵerengero cha ma signal-to-noise pa ranges yayitali."
— Mtsogoleri wa Ukadaulo wa RichPCBA
"Kwa kasitomala wopanga ma drone opindika ogwiritsa ntchito, kusintha kugwiritsa ntchito polyimide kumachepetsa kusweka kwa bolodi ndikuwonjezera moyo wosinthasintha ndi kanayi."
— Woyang'anira Pulojekiti, Gawo la Flex PCB
Lankhulani ndi Mainjiniya Athu Musanasankhe
Tathandiza opanga ma drone oposa 150 ku Europe, Middle East, ndi ku US kupanga ma PCB stackups oyenera cholinga. Kaya simukudziwa bwino za kutayika kwa dielectric, ma thermal coefficients, kapena kukhazikika kwa lamination, tili pano kuti tikuthandizeni.
