Ma PCB a Ceramic amapangidwa ndi gawo lapansi la ceramic, cholumikizira cholumikizira, ndi gawo lozungulira. Mosiyana ndi MCPCB, ma PCB a ceramic alibe wosanjikiza, ndipo kupanga gawo lozungulira pagawo la ceramic ndikovuta. Kodi ma PCB a ceramic amapangidwa bwanji? Popeza zida za ceramic zidagwiritsidwa ntchito ngati magawo a PCB, njira zingapo zidapangidwa kuti apange gawo lozungulira pagawo la ceramic. Njirazi ndi HTCC, DBC, filimu yokhuthala, LTCC, film film, ndi DPC.

Mtengo wa HTCC

ubwino: mkulu structural mphamvu; mkulu matenthedwe madutsidwe; kukhazikika kwamankhwala kwabwino; kachulukidwe wama waya okwera; Satifiketi ya RoHS

kuipa: osauka dera madutsidwe; kutentha kwambiri kwa sintering; mtengo wokwera

HTCC ndi chidule cha ceramic yotentha kwambiri yoyaka moto. Ndi njira yoyamba yopanga ceramic PCB. Zida za ceramic za HTCC ndi alumina, mullite, kapena aluminium nitride.

Kupanga kwake ndi:

Pa 1300-1600 ℃, ufa wa ceramic (wopanda galasi wowonjezera) umatenthedwa ndikuuma kuti ukhale wolimba. Ngati mapangidwewo amafunikira m'mabowo, mabowo amabowoleredwa pagawo la gawo lapansi.

Pa kutentha komweko, chitsulo chosungunuka-chotentha kwambiri chimasungunuka ngati phala lachitsulo. Chitsulo chikhoza kukhala tungsten, molybdenum, molybdenum, manganese, ndi zina zotero. Chitsulo chikhoza kukhala tungsten, molybdenum, molybdenum, ndi manganese. Phala lachitsulo limasindikizidwa molingana ndi kapangidwe kake kuti apange gawo lozungulira pa gawo lapansi.

Kenako, 4% -8% sintering aid imawonjezedwa.

Ngati PCB ndi multilayer, zigawo ndi laminated.

Kenako pa 1500-1600 ℃, kuphatikiza konseko kumapangidwa kuti apange matabwa a ceramic.

Pomaliza, chigoba cha solder chimawonjezeredwa kuti chiteteze gawo la dera.

Thin Film Ceramic PCB Manufacturing

Ubwino: kutentha kwapansi kupanga; chizungulire chabwino; bwino pamwamba flatness

Zoipa: zida zopangira zokwera mtengo; sangakhoze kupanga mabwalo atatu-dimensional

Chosanjikiza chamkuwa pa filimu yopyapyala ya ceramic PCBs imakhala ndi makulidwe ang'onoang'ono kuposa 1mm. Zida zazikulu za ceramic za PCBs za ceramic zoonda ndi aluminiyamu ndi aluminium nitride. Kupanga kwake ndi:

Gawo lapansi la ceramic limatsukidwa poyamba.

M'malo opanda vacuum, chinyezi pagawo la ceramic chimasinthidwa kukhala nthunzi.

Kenako, wosanjikiza mkuwa aumbike pa ceramic gawo lapansi pamwamba ndi magnetron sputtering.

Chithunzi chozungulira chimapangidwa pazitsulo zamkuwa ndi teknoloji ya yellow-light photoresist.

Kenako mkuwa wochuluka umachotsedwa ndi etching.

Pomaliza, chigoba cha solder chimawonjezeredwa kuti chiteteze dera.

Mwachidule: filimu yopyapyala ya ceramic PCB yamalizidwa mumkhalidwe wopanda vacuum. Tekinoloje ya yellow light lithography imalola kulondola kwambiri kuzungulira. Komabe, kupanga mafilimu opyapyala kuli ndi malire a makulidwe amkuwa. Ma PCB a ceramic ocheperako amakanema ndi oyenera kuyika mwatsatanetsatane komanso zida zazing'ono.

DPC

Ubwino: palibe malire ku mtundu wa ceramic ndi makulidwe; chizungulire chabwino; kutentha kwapansi kupanga; bwino pamwamba flatness

Zoyipa: zida zopangira zokwera mtengo

DPC ndiye chidule cha mkuwa wopangidwa mwachindunji. Imayamba kuchokera ku njira yopangira filimu yopyapyala ya ceramic ndikuwongolera powonjezera makulidwe amkuwa kudzera pakumata. Kupanga kwake ndi:

Njira yofananira yopangira mafilimu ochepetsetsa mpaka chithunzi chozungulira chisindikizidwe pafilimu yamkuwa.

Kuchuluka kwa mkuwa wozungulira kumawonjezedwa ndi plating.

Filimu yamkuwa imachotsedwa.

Pomaliza, chigoba cha solder chimawonjezeredwa kuti chiteteze dera.

Mapeto

Nkhaniyi ikutchula njira zopangira za ceramic PCB. Imayambitsa njira zopangira ceramic PCB ndikuwunika mwachidule njirazo. Ngati mainjiniya/makampani/mabungwe akufuna kukhala ndi ma PCB a ceramic opangidwa ndikusonkhanitsidwa, YMSPCB ibweretsa 100% zokhutiritsa kwa iwo.
