    Ikibaho cyanditseho Ceramic

    Abakoresha benshi ba PCB basanga PCBs ceramic zifite inyungu kurenza PCB gakondo ikozwe mubindi bikoresho. Iyi nyungu ni ukubera ko ceramic PCBs itanga insimburangingo ikwiranye nu miyoboro ya elegitoronike ifite ubushyuhe bwinshi hamwe na coefficient nkeya yo kwagura ubushyuhe (CTE).


    Ceramic PCB irahuze cyane kandi irashobora gusimbuza PCB yuzuye gakondo hamwe nigishushanyo gito kandi cyongerewe imikorere. Urashobora kubikoresha mubicuruzwa byinshi, nkumuzunguruko ufite imbaraga nyinshi, chip-on-board modules hamwe na sensor yegeranye.

      Ubwoko bukuru bwa Ceramic PCB

      Uhereye kurwego rwa substrate, ceramic PCBs zirimo aluminium, AIN, BeO, Si₃N₄, imbaho ​​za Hybrid substrate, nibindi.
      Ububiko bwa Ceramic PCBs busanzwe bugizwe na ceramic cores, hamwe na alumina na nitride ya aluminium (AIN) ari bibiri mubwoko bwibanze. Ubu bwoko bwombi bwibibaho butanga ubushyuhe bwiza kuruta ibyuma bya PCBs kuko ntagikenewe urwego rwamashanyarazi hagati yibyingenzi nizunguruka. Shakisha byinshi kuri ubu bwoko bubiri bwubwoko bwa ceramic PCB hepfo:

      AIN:

      Kumashanyarazi yumuriro mwinshi, imbaho ​​ya nitride ya aluminium nibyiza, itanga hejuru ya 150 w / mK. AIN ni ihitamo ryambere kubera izindi mpamvu nazo, nkibintu byiza bya dielectric, kutitabira hamwe na chimique itandukanye ya semiconductor hamwe na CTE nkeya.

      Alumina:

      Kubera ko ikibaho cya aluminium nitride gihenze, abahitamo PCBs zihenze zihenze barashobora kwisanga hamwe na Alumina. Izi PCB zakozwe muri oxyde ya aluminium kandi zitanga hafi 18-36 w / mK.

      Ibyiza bya Ceramic PCB

      Gukora neza mubushyuhe bugera kuri dogere selisiyusi 350
      Ishyirwa mu bikorwa ryoroheje ryumuzunguruko ukurikirana
      Imikorere idasanzwe-inshuro nyinshi
      Gupakira ibintu byinshi, hamwe nuburyo bwo kuza mubikoresho bya hermetic kugirango wirinde kwinjiza amazi
      Kurwanya isuri ikaze
      Iyindi nyungu ya ceramic PCB nigiciro cyo hasi muri sisitemu igiciro, gishobora kuba cyigiciro cyinshi kubipfunyika bwuzuye, kubera ko ufite parallel yo gutunganya ibice.
