Zochepa zogwiritsira ntchito zitsulo za ceramic pama board ozungulira

Mu positi iyi yabulogu, tikambirana zoletsa kugwiritsa ntchito matabwa a ceramic pama board ozungulira ndikuwunika zida zina zomwe zitha kuthana ndi izi.

Ceramics akhala akugwiritsidwa ntchito m'mafakitale osiyanasiyana kwa zaka mazana ambiri, kupereka ubwino wambiri chifukwa cha katundu wawo wapadera. Chimodzi mwazinthu zotere ndikugwiritsa ntchito ziwiya zadothi pama board ozungulira. Ngakhale ma ceramics amapereka maubwino ena pamapulogalamu a board board, alibe malire.

Chimodzi mwazoletsa zazikulu zogwiritsira ntchito ceramic pama board ozungulira ndizovuta zake.Ma Ceramics ndi zinthu zomwe zimawonongeka ndipo zimatha kusweka kapena kusweka chifukwa cha kupsinjika kwamakina. Kusakhazikika uku kumapangitsa kuti zikhale zosayenera kugwiritsa ntchito zomwe zimafunikira kugwiridwa nthawi zonse kapena zomwe zimakumana ndi zovuta. Poyerekeza, zida zina monga ma epoxy board kapena ma flexible substrates ndi olimba kwambiri ndipo amatha kupirira kapena kupindika popanda kusokoneza kukhulupirika kwa dera.

Cholepheretsa china cha ceramic ndi kusayenda bwino kwa matenthedwe.Ngakhale zitsulo za ceramic zili ndi mphamvu zotetezera magetsi, sizimataya kutentha bwino. Kuchepetsa uku kumakhala nkhani yofunika kwambiri pamapulogalamu omwe ma board ozungulira amatulutsa kutentha kwakukulu, monga zamagetsi zamagetsi kapena ma frequency apamwamba. Kukanika kutulutsa kutentha kungayambitse kulephera kwa chipangizo kapena kuchepa kwa magwiridwe antchito. Mosiyana ndi izi, zida monga zitsulo zazikuluzikulu zosindikizidwa matabwa (MCPCB) kapena ma polima opangira thermally amapereka katundu wabwino wowongolera kutentha, kuwonetsetsa kuti kutentha kumataya mokwanira ndikuwongolera kudalirika konsekonse.

Kuphatikiza apo, zitsulo za ceramic sizoyenera kugwiritsidwa ntchito pafupipafupi.Popeza ma ceramics amakhala ndi ma dielectric pafupipafupi, amatha kuyambitsa kutayika kwa ma sign ndi kupotoza pama frequency apamwamba. Izi zimachepetsa kugwiritsidwa ntchito kwawo pamapulogalamu omwe kukhulupirika kwa ma siginecha ndikofunikira, monga kulumikizana ndi zingwe, makina a radar, kapena ma microwave. Zida zina monga ma laminates apamwamba kwambiri kapena ma crystal polymer amadzimadzi (LCP) amapereka ma dielectric otsika, amachepetsa kutayika kwa ma siginecha ndikuwonetsetsa kuti magwiridwe antchito apamwamba kwambiri.

Cholepheretsa china cha matabwa a ceramic ndi kusinthasintha kwawo kochepa.Ceramics nthawi zambiri imakhala yolimba komanso yovuta kupanga kapena kusintha ikapangidwa. Izi zimachepetsa kugwiritsa ntchito kwawo pamapulogalamu omwe amafunikira ma geometri ozungulira, mawonekedwe achilendo, kapena mapangidwe ovuta. Mosiyana ndi izi, ma flexible printed circuit board (FPCB), kapena ma organic substrates, amapereka kusinthasintha kwakukulu, kulola kupanga ma board opepuka, ophatikizika, komanso opindika.

Kuphatikiza pa zolephera izi, zoumba za ceramic zitha kukhala zokwera mtengo poyerekeza ndi zida zina zomwe zimagwiritsidwa ntchito pama board ozungulira.Njira yopangira zitsulo za ceramic ndizovuta komanso zogwira ntchito kwambiri, zomwe zimapangitsa kuti kupanga kwapamwamba kukhale kopanda mtengo. Mtengowu ukhoza kukhala wofunikira kwambiri kwa mafakitale omwe akufuna njira zotsika mtengo zomwe sizisokoneza magwiridwe antchito.

Ngakhale ma ceramics angakhale ndi malire pa ntchito zama board board, amakhalabe othandiza m'malo enaake.Mwachitsanzo, zitsulo za ceramic ndi njira yabwino kwambiri yogwiritsira ntchito kutentha kwakukulu, kumene kukhazikika kwawo kwabwino kwa kutentha ndi mphamvu zamagetsi ndizofunika kwambiri. Amagwiranso bwino m'malo omwe kukana mankhwala kapena dzimbiri ndikofunikira.

Powombetsa mkota,zitsulo zadothi zili ndi ubwino ndi malire pamene zikugwiritsidwa ntchito pamagulu ozungulira. Ngakhale kulimba kwawo, kusachita bwino kwamafuta, kusinthika pang'ono, kuchepa kwafupipafupi, komanso kutsika mtengo kwazomwe amazigwiritsa ntchito pazinthu zina, zoumba zikadali ndi zinthu zapadera zomwe zimawapangitsa kukhala othandiza pazochitika zinazake. Pamene teknoloji ikupitirirabe patsogolo, zipangizo zina monga MCPCB, ma polima a thermally conductive, laminates apadera, FPCB kapena LCP substrates akutuluka kuti athetse malirewa ndikupereka ntchito yabwino, kusinthasintha, kayendetsedwe ka kutentha ndi mtengo wa ntchito zosiyanasiyana zama board opindula.
