Okhwima-Flex Board Au/Ni Mtundu
b Chophimba chagolide chingagawidwe m'magulu agolide woonda ndi golide wokhuthala malinga ndi makulidwe ake. Kawirikawiri, golide wochepera 4u”(0.41um) amatchedwa golide woonda, pomwe golide woposa 4u” amatchedwa golide wokhuthala. ENIG ingapange golide woonda wokha, osati golide wokhuthala. Chophimba chagolide chokha ndi chomwe chingapange golide woonda komanso wokhuthala. Kukhuthala kwakukulu kwa golide wokhuthala pa bolodi losinthasintha kumatha kukhala kuposa 40u”. Golide wokhuthala amagwiritsidwa ntchito makamaka m'malo ogwirira ntchito omwe ali ndi zofunikira zomangira kapena kukana kuvala.
b Chophimba chagolide chingagawidwe m'magulu awiri: golide wofewa ndi golide wolimba malinga ndi mtundu wake. Golide wofewa ndi golide wamba woyeretsedwa, pomwe golide wolimba ndi wokhala ndi cobalt. Chifukwa chakuti cobalt imawonjezeredwa, kuuma kwa golide kumawonjezeka kwambiri kuposa 150HV kuti ikwaniritse zofunikira pakukana kutopa.
Ubwino wa Rigid-Flex Board
Masiku ano, mapangidwe akuchulukirachulukira kutsata kuchepetsedwa kwa zinthu, mtengo wotsika komanso kuthamanga kwambiri, makamaka pamsika wa zida zam'manja, zomwe nthawi zambiri zimakhala ndi ma circuits amagetsi okwera kwambiri. Kugwiritsa ntchito Rigid-Flex Boards kudzakhala chisankho chabwino kwambiri pazida zolumikizirana kudzera mu IO. Ubwino waukulu usanu ndi uwiri womwe umadza chifukwa cha zofunikira pakupanga kuphatikiza zida zosinthika za bolodi ndi zida zolimba za bolodi popanga, kuphatikiza zida ziwiri za substrate ndi prepreg, kenako kukwaniritsa kulumikizana kwamagetsi pakati pa ma conductor kudzera m'mabowo odutsa kapena ma vias osawoneka/obisika ndi awa:
a. Kusonkhana kwa 3D kuti muchepetse ma circuits
b. Kudalirika kwabwino kwa kulumikizana
c. Chepetsani chiwerengero cha zigawo ndi zigawo
d. Kusasinthasintha kwabwino kwa impedance
e. Angathe kupanga kapangidwe ka zinthu zovuta kwambiri
f. Khazikitsani kapangidwe ka mawonekedwe kosavuta
g. Chepetsani kukula
Kugwiritsa ntchito
Kugwiritsa Ntchito Bodi Lolimba (onani chithunzi 3-1 kuti mudziwe zambiri)
PCB yolimba ndi bolodi yophatikizana yokhala ndi mawonekedwe a bolodi yosinthasintha ya dera komanso bolodi yolimba ya dera, yomwe imagwiritsidwa ntchito kwambiri m'minda motere:
1. Gawo la zamagetsi: Ma PCB okhwima amagwiritsidwa ntchito kwambiri pazinthu zamagetsi monga mafoni am'manja, mapiritsi, zida zanzeru zovalidwa, makamera, zojambulira makanema, zowerengera, ma drones ndi zowunikira zolimbitsa thupi. Ponena za magwiridwe antchito, ma board ake olimba komanso osinthasintha amatha kulumikiza ma PCB osiyanasiyana olimba ndi zigawo zake mwanjira ya magawo atatu. Pa kuchuluka komweko kwa dera, imatha kuwonjezera malo ogwiritsira ntchito a PCB, kukweza mphamvu yake yonyamulira dera, ndikuchepetsa malire otumizira chizindikiro ndi kuchuluka kwa zolakwika za kulumikizana. Ponena za kapangidwe kake, ma PCB okhwima ndi opepuka komanso owonda, zomwe zimathandiza kuti mawaya azisinthasintha, zomwe zimathandiza kwambiri kuchepetsa voliyumu ndi kulemera.
2. Gawo la magalimoto: Ma PCB osinthasintha amagwiritsidwa ntchito kwambiri m'makina amagetsi agalimoto, kuphatikiza mabatani olumikizira bolodi la amayi ku chiwongolero, kulumikizana pakati pa chophimba cha makina a kanema agalimoto ndi gulu lowongolera, kulumikizana kwa makiyi amawu kapena ntchito pazitseko zam'mbali, makina ojambula zithunzi za radar, masensa, makina olumikizirana ndi magalimoto, kuyenda kwa satellite, bolodi lolumikizira gulu lowongolera mipando yakumbuyo ndi chowongolera chakutsogolo, ndi makina owonera akunja.
3. Gawo la zida zachipatala: Kugwiritsa ntchito ma PCB osasunthika mu zida zachipatala kukuchulukirachulukira, monga zida zowunikira zizindikiro, zida zochiritsira, zida zojambulira zithunzi, zida zochiritsira thupi, zida zoyezera mtima, ma endoscope, zida zowongolera ma ultrasound, ndi zina zotero. Zogulitsa m'magawo awa zimafuna kudalirika kwambiri, kulondola kwambiri, kutayika kochepa kwa impedance, khalidwe lonse lotumizira ma signal, kulimba, ndi zina zotero. Chifukwa cha zovuta za njira yopangira komanso kutulutsa kochepa, mtengo wopanga ndi wokwera.
4. Malo olamulira mafakitale: Ma PCB osinthasintha amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikizapo ma satellite opanga, ma radar system, kulumikizana opanda zingwe, zida zoyezera ndi zowongolera za laser, masensa, ma nuclear magnetic analyzer, zida za X-ray, ma infrared analyzer, ndi zina zotero.
