Rigid-flex board / 8 wosanjikiza PCB yamakutu am'makutu a Bluetooth
Gulu la Rigid-Flex PCBs (onani chithunzi 1 kuti mudziwe zambiri)
A rigid-flex ndi bolodi lomwe limaphatikiza kukhazikika ndi kusinthasintha, kukonza zonse zolimba za bolodi lokhazikika komanso kusinthasintha kwa bolodi losinthika.
Gawo laling'ono: TG yapakatikati, TG yapamwamba, yotsika kwambiri ya dielectric, yotsika Df FR4, zinthu zama frequency apamwamba.
Mitundu ya substrate: Shengyi, Tenghui, Lianmao, Rogers, Panasonic, DuPont, Taihong.
Kumaliza pamwamba: HASL, HASL(Pb Yaulere), ENIG, Tin Yomiza, Siliva Womiza, Kupaka Golide, OSP, ENIG + OSP, ENEPIG.
Rigid-Flex Board Au/Ni Type
b Kuyika golide kumatha kugawidwa kukhala golide woonda ndi golide wandiweyani molingana ndi makulidwe. Nthawi zambiri, golide pansi pa 4u”(0.41um) amatchedwa golide woonda, pomwe golide woposa 4u” amatchedwa golide wandiweyani. ENIG imatha kupanga golide wochepa thupi, osati golide wandiweyani. Kuyika golide kokha kungapange golide woonda komanso wandiweyani. Kukula kwakukulu kwa golide wandiweyani pa bolodi yosinthika kumatha kupitilira 40u ”. Golide wandiweyani amagwiritsidwa ntchito makamaka m'malo ogwirira ntchito omwe ali ndi zofunikira zomangira kapena kukana kuvala.
b Kuyika kwa golide kumatha kugawidwa kukhala golide wofewa ndi golide wolimba potengera mtundu. Golide wofewa ndi golide wamba, pomwe golide wolimba ndi cobalt wokhala ndi golide. Ndi chifukwa chakuti cobalt amawonjezedwa kuti kuuma kwa golide wosanjikiza kumawonjezeka kwambiri kuposa 150HV kuti akwaniritse zofunikira zokana kuvala.
Ubwino wa Rigid-Flex Board
Masiku ano, mapangidwe akutsata kwambiri miniaturization, mtengo wotsika komanso kuthamanga kwambiri kwa zinthu, makamaka pamsika wa mafoni am'manja , zomwe nthawi zambiri zimaphatikizapo mabwalo amagetsi apamwamba kwambiri. Kugwiritsa ntchito Rigid-Flex Boards kudzakhala chisankho chabwino kwambiri pazida zotumphukira zolumikizidwa kudzera pa IO. Zopindulitsa zisanu ndi ziwiri zazikulu zomwe zimabweretsedwa ndi kapangidwe kazinthu zophatikizira zida zosinthika za board ndi zida zolimba za board popanga, kuphatikiza zida zam'munsi ziwiri ndi prepreg, kenako ndikukwaniritsa kulumikizana kwamagetsi kwa ma conductor kudzera m'mabowo kapena akhungu / kukwiriridwa. :
a. Msonkhano wa 3D kuti muchepetse madera
b. Kudalirika kolumikizana bwino
c. Chepetsani chiwerengero cha zigawo ndi zigawo
d. Kusasinthasintha kwabwino kwa impedance
e. Itha kupanga mapangidwe ovuta kwambiri a stacking
f. Pangani mawonekedwe owoneka bwino
g. Chepetsani kukula
Kugwiritsa ntchito
Kufunsira kwa Rigid-Flex Board (onani chithunzi 3-1 kuti mumve zambiri)
Rigid-flex PCB ndi gulu lophatikizika lomwe lili ndi mawonekedwe a bolodi lokhazikika komanso lokhazikika, lomwe limagwiritsidwa ntchito kwambiri m'magawo motere:
1. Zamagetsi:Ma PCB a Rigid-flex amagwiritsidwa ntchito kwambiri pazinthu zamagetsi monga mafoni am'manja, mapiritsi, zida zovala zanzeru, makamera, zojambulira makanema, zowerengera, ma drones ndi zowunikira zolimbitsa thupi. Pankhani ya magwiridwe antchito, matabwa ake okhwima ndi osinthika amatha kulumikiza ma PCB okhwima osiyanasiyana ndi zigawo zake m'njira zitatu. Pa kachulukidwe wadera lomwelo, imatha kukulitsa gawo lonse la PCB, kupititsa patsogolo mphamvu yake yonyamulira dera, ndikuchepetsa malire otumizira ma siginecha ndi kulakwitsa kwa msonkhano kwa omwe amalumikizana nawo. Kunena mwamawonekedwe, ma PCB olimba-osinthika ndi opepuka komanso owonda, omwe amalola mawaya osinthika, omwe amathandiza kwambiri kuchepetsa voliyumu ndi kulemera kwake.
2. Malo amagalimoto:Ma PCB osasunthika nthawi zambiri amagwiritsidwa ntchito pamakina apamagetsi apagalimoto, kuphatikiza mabatani olumikizira bolodi la amayi ndi chiwongolero, kulumikizana pakati pa kanema wagalimoto yagalimoto ndi gulu lowongolera, kulumikizana kwa makiyi omvera kapena ntchito pazitseko zam'mbali, reverse radar imaging system. , masensa, kayendedwe ka galimoto, kayendedwe ka satana, bolodi logwirizanitsa gulu lakumbuyo lakumbuyo ndi woyang'anira kutsogolo, ndi njira yodziwira kunja.
3. Gawo la zida zachipatala:Kugwiritsa ntchito ma PCB osasunthika pazida zamankhwala kukuchulukirachulukira, monga zida zowunikira zizindikiro, zida zochizira, zida zofananira, zida za physiotherapy, mtima pacemaker, ma endoscopes, zida zowongolera ma ultrasound, ndi zina zambiri. kulondola, kutayika kochepa kwa impedance, khalidwe lathunthu la kufalitsa chizindikiro, kukhazikika, ndi zina zotero.
4. Malo owongolera mafakitale:Ma PCB osasunthika amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza ma satelayiti opangira, makina a radar, kulumikizana opanda zingwe, kuyeza kwa laser ndi zida zowongolera, masensa, zida zanyukiliya maginito, zida za X-ray, zowunikira ma infrared, ndi zina zambiri.
