Ceramic PCBs dzinoshandisa ceramics semidziyo yavo yekutanga, uye inoda yakanyanya kupisa tembiricha yekugadzira kupfuura mamwe maPCB. SePCB base zvinhu, ceramics inoshandiswa kuPCBs ine zvakanakira zvese FR4 nesimbi. FR4 zvinhu zvinodzivirira magetsi, asi iyo yekupisa conductivity haina kunaka; aruminiyamu nemhangura zvine yakanakisa thermal conductivity, asi iwo makondakita. Ceramic PCBs ine yakanaka yekupisa conductivity uye haidi yemagetsi yekuvharisa layer sezvo ceramics yakanaka insulators.

Kana zvedongo PCBs akaiswa pamwe LED machipisi, ICs, uye zvimwe zvinoriumba, vanova ceramic PCBAs. Ma LED anogona kuunganidzwa paceramic PCBs newaya bonding kana flip-chip nzira. Ceramic PCBAs kazhinji ndiwo mativi epakati mu-high-simba uye akakwira-frequency application, senge mota-scale magetsi controller, anochinja-chinja optical masisitimu, anochinjanisa anoshandura, solar simba mabhatiri, akakwira-azvino ma LED mwenje...

Sei ceramic PCB yakakurumbira zvakadaro?

Kuwedzera Kwekupisa Kwepamusoro

Chikonzero chekutanga nei mabhodhi eceramic akakurumbira muchikamu chemagetsi ndiko kuwedzera kwekuwedzera kwemafuta ecoefficient. Zvakanaka kuziva kuti iyo ceramic base heat transmission inofanana nesilicon uye inogona kuita sechinhu chekubatanidza. Kunze kwezvo, iwe unogona kuishandisa seyega. Nokudaro, kune zvakanyanya kushandiswa kwemafuta ekupisa emapuranga e ceramic, kunyange mumamiriro ezvinhu asina kunaka.

Kugadzikana

Iko kushandiswa kweceramic kunounza yakagadzikana dielectric kugona, uye iwe unogona kushandura chiyero kuita chikamu chekurasikirwa neradiofrequency kuti uwedzere simba rechishandiso chako. Zvakadaro, kunyangwe nekuoma kwepamusoro, zvinhu zveceramic zvinouya nekupokana nekupokana nekukukurwa kwemakemikari. Ceramic's chemical resistance inogona kuchinja kupikisa zvinwiwa uye mwando.

Zvakasiyana-siyana

Iwe unogona kugadzira akati wandei makesi ekubatanidza simbi yepakati bhodhi ine yakakwira yekuwedzera kupisa. Kunze kwezvo, iwe unogona kuramba uchishandura simbi yesimbi kuita yakavimbika conductors uchishandisa sintering maitiro. Naizvozvo, kushandiswa kweceramic PCB kunobatsira nekuda kwekupisa kwayo kwepamusoro.

Kugara kwenguva refu

Iyo ceramic board yekugadzira maitiro inogadzira kusimba kuburikidza nekushandisa yakasarudzika zvivakwa, sekuoma. Izvo zvinodzivirira PCB yako kubvaruka uye kubvaruka. Saka iwe unogona kuva nechivimbo chekuti hausi kuzochinja PCB yako nekukurumidza nekuda kwekunonoka kwayo kuchembera. Zvakare, iyo yakakwira yekupisa yekupokana kweceramic PCB inoita kuti ifungidzire yakadzikira yekuora maitiro.

Kuchinjika

Pakupedzisira, kushandiswa kwesimbi cores kunogona kushanda sevatakuri vasingachinjiki vanopa kuoma kwemagetsi. Ichi chivakwa chinoita kuti zvive nyore kushandisa ceramic PCBs mune chero mamiriro ezvinhu nekuda kwekupokana kwakanyanya kwekuora uye zvakajairwa kupfeka uye kubvaruka.

Zvakanakira zveceramic PCB

Kupisa kupisa ndiyo yakakosha kubatsirwa iyo ceramic ine pamusoro pezvakajairwa zvinhu zvakaita seFR-4 uye simbi yakapfeka PCB. Nemhaka yokuti zvikamu zvinoiswa zvakananga pamapuranga, uye hapana chidimbu chekuzviparadzanisa, kuyerera kwekupisa kuburikidza nemapuranga kunonyanya kushanda. Pamusoro pezvo, zvinhu zveceramic zvinogona kutambura nekushisa kwakanyanya kwekushanda (kusvika 350 ° C), chii zvakare, ine yakaderera coefficient yekuwedzera kwekupisa (CTE), ichibvumira mamwe ekuenderana sarudzo dzePCB dhizaini.

Kuenzaniswa neyechinyakare maPCB ane substrate zvinhu ari epoxy girazi faibha, polyimide, polystyrene uye phenolic resin, ceramic PCBs ine zvinotevera zvivakwa:

Excellent thermal conductivity

Ramba kukukurwa kwemakemikari

Inopindirana mechanical intensity

Ita kuti zvive nyore kushandisa high-density tracing

CTA chikamu kuenderana

Pfungwa yekupedzisira

MaPCB echinyakare akasanganiswa neorganic foundation substrates anofambira mberi akananga kune imwe inoshamisa density, kuvimbika kwepamusoro, kunyatsoita zvakanaka, uye kusimba nekuunzwa kwechip tekinoroji muindasitiri yemagetsi. Ceramic circuit boards zvechokwadi rudzi rutsva rwePCB iri kuwana mukurumbira muindasitiri yemagetsi nekuda kwehunhu hwavo hwakasiyana.

Ceramic PCBs inopa akawanda mabhenefiti pane akajairwa mabhodhi. Ceramic PCBs inonyanya kuchinjika, haina kuomesesa, uye inoshanda zvirinani pane akajairwa edunhu mabhodhi nekuda kwehukuru hwekupisa conductivity uye yakaderera yekuwedzera coefficient (CTE). Mainjiniya anotenda kuti maPCB aya ndiyo yakanakisa sarudzo yeminiaturizing yekucheka-kumucheto magetsi emagetsi. Ndinovimba, iwe une zano reKuziva Yakanyanya Ceramic PCB uye ikozvino unogona kukusarudzira yakanakira iwe.
