Ma PCB a Ceramic amagwiritsa ntchito zoumba ngati zida zawo, ndipo amafunikira kutentha kwapamwamba kwambiri kuposa ma PCB ena. Monga zida zoyambira za PCB, zoumba zomwe zimagwiritsidwa ntchito pa PCB zimakhala ndi zabwino zonse za FR4 ndi zitsulo. Zida za FR4 ndizotsekera magetsi, koma matenthedwe amatenthedwe ndi osauka; aluminiyamu ndi mkuwa ali ndi matenthedwe abwino kwambiri, koma ndi ma conductor. Ma PCB a Ceramic ali ndi matenthedwe abwino ndipo safuna kusanjikiza magetsi chifukwa zoumba ndi zoteteza bwino.

Ma PCB a ceramic akayikidwa ndi tchipisi ta LED, ma IC, ndi zinthu zina, amakhala ma PCBA a ceramic. Ma LED amatha kusonkhanitsidwa pa ma PCB a ceramic pogwiritsa ntchito ma waya kapena njira yopindika. Ma Ceramic PCBAs nthawi zambiri amakhala mbali zazikuluzikulu zamagetsi apamwamba komanso othamanga kwambiri, monga zowongolera mphamvu zamagalimoto, makina owoneka bwino, osinthira osinthira, mabatire amagetsi adzuwa, nyali zamakono za LED...

Chifukwa chiyani ceramic PCB ndiyotchuka kwambiri?

Kukula Kwapamwamba Kwambiri

Chifukwa choyamba chomwe matabwa a ceramic ndi otchuka kwambiri mu gawo lamagetsi ndikukulitsa kwawo kokwanira kwamafuta. Ndibwino kuzindikira kuti kutentha kwa ceramic m'munsi kumafanana ndi silicon ndipo kumatha kukhala ngati cholumikizira. Kupatula apo, mutha kugwiritsa ntchito ngati chodzipatula. Choncho, pali ntchito pazipita kwa matenthedwe katundu wa ceramic matabwa, ngakhale chokhwima zinthu.

Kukhazikika

Kugwiritsa ntchito kwa ceramic kumabweretsa mphamvu yokhazikika ya dielectric, ndipo mutha kusintha kuchuluka kwake kukhala kutayika pang'ono kwa radiofrequency kuti muwonjezere mphamvu ya chipangizo chanu. Komabe, ngakhale ndizovuta kwambiri, zida za ceramic zimabwera ndi kukana kwachilengedwe motsutsana ndi kukokoloka kwa mankhwala. Kulimbana ndi mankhwala a Ceramic kumatha kusintha kukana zakumwa ndi chinyezi.

Kusinthasintha

Mutha kupanga zingapo zogwiritsiridwa ntchito kuti muphatikize bolodi loyambira lachitsulo ndi kukulitsa kwamafuta ambiri. Kupatula apo, mutha kusandutsa pachimake chachitsulo kukhala ma conductor odalirika pogwiritsa ntchito njira ya sintering. Choncho, ntchito ceramic PCB ndi opindulitsa chifukwa cha kutentha kwambiri processing.

Kukhalitsa

Njira yopangira matabwa a ceramic imapangitsa kukhazikika pogwiritsa ntchito zinthu zapadera, monga kulimba. Izi zimalepheretsa PCB yanu kuti isawonongeke. Chifukwa chake mutha kukhala otsimikiza kuti simudzasintha PCB yanu posachedwa chifukwa chakukalamba kwake pang'onopang'ono. Komanso, kukana kwamafuta ambiri a ceramic PCB kumapangitsa kuti iganize njira yowola yocheperako.

Kusinthasintha

Pomaliza, kugwiritsa ntchito zida zachitsulo kumatha kukhala ngati zonyamulira zosasinthika zomwe zimapereka kuuma kwamakina. Katunduyu amapangitsa kuti zikhale zosavuta kugwiritsa ntchito ma PCB a ceramic mumtundu uliwonse chifukwa cha kukana kwambiri kwa dzimbiri komanso kung'ambika kwanthawi zonse.

Ubwino wa ceramic PCB

Kutentha kwapang'onopang'ono ndiye phindu lalikulu lomwe ceramic ili ndi zida zambiri wamba monga FR-4 ndi PCB yovala zitsulo. Chifukwa chakuti zigawozo zimayikidwa mwachindunji pa matabwa, ndipo palibe wosanjikiza wodzipatula, kutuluka kwa kutentha kupyolera mu matabwa kumakhala kothandiza kwambiri. Kuphatikiza apo, zinthu za ceramic zimatha kuvutitsidwa ndi kutentha kwakukulu (mpaka 350 ° C), kuonjezera apo, zimakhala ndi coefficient yotsika kwambiri yakukula kwamafuta (CTE), kulola kuti pakhale zosankha zina zofananira pamapangidwe a PCB.

Poyerekeza ndi ma PCB achikhalidwe omwe gawo lawo la gawo lapansi ndi epoxy glass fiber, polyimide, polystyrene ndi phenolic resin, ma PCB a ceramic amakhala ndi izi:

Wabwino matenthedwe madutsidwe

Pewani kukokoloka kwa mankhwala

Yogwirizana makina mwamphamvu

Pangani kukhala kosavuta kukhazikitsa kutsata kwapamwamba kwambiri

Kugwirizana kwa chigawo cha CTA

Mfundo yotsiriza

Ma PCB achikhalidwe ophatikizidwa ndi maziko a organic akupita patsogolo mpaka kuchulukira kwina kodabwitsa, kudalirika kwakukulu, kulondola kwabwino, komanso kulimba poyambitsa ukadaulo wa chip mumakampani amagetsi. Ma board a Ceramic ndi mtundu watsopano wa PCB womwe ukudziwika bwino pamakampani opanga zamagetsi chifukwa cha mawonekedwe awo apadera.

Ma PCB a Ceramic amapereka maubwino ambiri kuposa matabwa wamba. Ma PCB a Ceramic ndi osinthika, ocheperako, ndipo amagwira ntchito bwino kuposa ma board ozungulira wamba chifukwa cha kutentha kwapamwamba komanso kutsika kwapakatikati (CTE). Mainjiniya amakhulupirira kuti ma PCB awa ndiye chisankho chabwino kwambiri chopangira zida zamagetsi zamagetsi. Tikukhulupirira, muli ndi lingaliro la Momwe Mungadziwire PCB Yabwino Kwambiri ya Ceramic ndipo tsopano mutha kukusankhirani yabwino.
