Kodi Mungasankhe Bwanji Zinthu Zoyenera za PCB pa Machitidwe Apamwamba a Radar?
Kusankha zinthu za PCB ndikofunikira kwambiri pakupanga makina a radar, zomwe zimakhudza mwachindunji magwiridwe antchito, kudalirika, komanso mtengo. Ma radar osiyanasiyana, monga radar yamagalimoto ya millimeter-wave, radar yoteteza mpweya, ndi radar yowunikira pansi, amafunikira zinthu zinazake za PCB. Nkhaniyi ikupereka chitsogozo chatsatanetsatane chosankha zinthu zoyenera za PCB zama makina a radar kuti agwire bwino ntchito komanso moyenera.
Chifukwa chiyani Zinthu Zofunika pa PCB mu Radar Systems
Zofunikira pafupipafupi
Makina a radar amagwira ntchito m'malo okwera kwambiri, monga 24 GHz kapena 77 GHz pa radar yamagalimoto.
Zizindikiro zama frequency apamwamba zimafuna zipangizo zokhala ndi dielectric constant yotsika (Dk) ndi dielectric loss yotsika (Df) kuti zitsimikizire kukhulupirika kwa chizindikiro ndikuchepetsa kutayika.
Magwiridwe antchito a kasamalidwe ka kutentha
Makina a radar nthawi zambiri amagwira ntchito ndi mphamvu zambiri. Zipangizo zomwe zimakhala ndi kutentha kwambiri ndizofunikira kwambiri kuti kutentha kuchotsedwe bwino.
Kudalirika Pamikhalidwe Yovuta
Makina a radar a magalimoto ayenera kupirira kutentha kwambiri, chinyezi, ndi kugwedezeka.
Ma radar ankhondo amakumana ndi nyengo yoipa kwambiri, zomwe zimafuna zipangizo zolimba komanso zolimba.
Zipangizo Zodziwika za PCB za Machitidwe a Radar
Zipangizo za Rogers
Mitundu Yovomerezeka: Rogers 5880, Rogers 4350B
Zinthu Zofunika Kwambiri:
Chokhazikika cha dielectric chotsika komanso kutayika
Kukhazikika kwabwino kwambiri kwa kutentha ndi CTE yotsika (coefficient of thermal expansion)
Yoyenera kugwiritsa ntchito ma radar a ma millimeter-wave komanso ma radar a pafupipafupi kwambiri.
Milandu Yoyenera Kugwiritsa Ntchito: Rada ya mafunde a Millimeter, rada yankhondo, ma module olumikizirana pafupipafupi.
Zipangizo za Taconic
Mitundu Yovomerezeka: Taconic TLY, RF-35
Zinthu Zofunika Kwambiri:
Yotsika mtengo poyerekeza ndi zipangizo za Rogers
Kugwira ntchito pang'ono pa ntchito zogwiritsa ntchito pafupipafupi mpaka pamlingo wapamwamba.
Milandu Yoyenera Kugwiritsa Ntchito: Rada ya magalimoto, rada yowunikira ma frequency apakati.
Zipangizo Zosinthidwa za FR-4
Zinthu Zofunika Kwambiri:
Kugwiritsa ntchito ndalama zambiri
Kugwira ntchito bwino kudzera mu zokutira zapadera zogwiritsira ntchito pafupipafupi.
Makhalidwe Abwino Ogwiritsira Ntchito: Makina a radar odula mtengo, zida zazing'ono zowunikira.
Zipangizo za Polyimide (PI)
Zinthu Zofunika Kwambiri:
Zipangizo zosinthika zopangira mapangidwe ovuta
Makhalidwe abwino kwambiri a kutentha ndi makina.
Magwiritsidwe Abwino: Ma module ophatikizidwa a radar, makina osinthika a antenna.
Masitepe Osankha Zinthu Zoyenera za PCB
Sankhani Kutengera Mafupipafupi
Gwiritsani ntchito zinthu zotsika mtengo monga Rogers 5880 kuti mugwiritse ntchito radar ya pafupipafupi kwambiri.
Sankhani FR-4 yosinthidwa kuti igwiritsidwe ntchito mosavuta komanso mosavuta.
Ganizirani Zofunikira pa Mphamvu ndi Kutentha
Ma radar amphamvu kwambiri ayenera kugwiritsa ntchito zipangizo zomwe zimakhala ndi mphamvu yotenthetsera kutentha kwambiri, monga ma laminate okhala ndi zitsulo.
Yerekezerani ndi Mikhalidwe Yachilengedwe
Ma radar ankhondo ndi amlengalenga amapindula ndi zinthu zotentha kwambiri komanso zosagwira chinyezi monga PTFE kapena polyimide.
Kugwira Ntchito Moyenera ndi Mtengo
Pa mapulojekiti omwe ali ndi bajeti yochepa, sankhani FR-4 yosinthidwa pamene mukuonetsetsa kuti ikukwaniritsa zofunikira pakugwira ntchito.
Zolakwa Zofala mu Kusankha Zinthu Zofunika pa PCB
Kudalira Chinthu Chimodzi Chokha
Ma module osiyanasiyana a radar angafunike zipangizo zosiyanasiyana za PCB. Mwachitsanzo, ma module a RF amafuna ma Rogers, pomwe ma module owongolera angagwiritse ntchito FR-4.
Kuyang'ana Kasamalidwe ka Kutentha
Ngakhale zipangizo zitakhala zogwira ntchito bwino pa kutentha, mapangidwe oyenera a sinki yotenthetsera ndi ofunikira kuti kutentha kuthe bwino.
Kunyalanyaza Zovuta Zopanga
Zipangizo zogwira ntchito bwino nthawi zambiri zimafuna luso lapadera lokonza zinthu, choncho onetsetsani kuti wogulitsa wanu akhoza kuthana ndi zovutazi.
Kutsiliza: Chinsinsi cha Kugwira Ntchito Kwabwino Kwambiri kwa PCB ya Radar
Kusankha zinthu zoyenera za PCB ndikofunikira kuti makina a radar agwire bwino ntchito, kudalirika, komanso kugwiritsa ntchito bwino ndalama. Pa makina a radar omwe amagwiritsa ntchito pafupipafupi, Rogers ndi Taconic zipangizo zimapereka ntchito yabwino kwambiri. Pazinthu zomwe zimafuna ndalama zochepa, FR-4 yosinthidwa ingapereke njira ina yotsika mtengo.
Kugwirizana ndi wopanga PCB wodziwa bwino ntchito kumatsimikizira kusankha bwino zinthu ndi chithandizo cha kupanga mapulogalamu anu a radar.
