Ceramic PCBs yog tsim los ntawm ceramic substrate, txheej kev sib txuas, thiab txheej txheej hauv Circuit Court. Tsis zoo li MCPCB, ceramic PCBs tsis muaj txheej txheej rwb thaiv tsev, thiab kev tsim cov txheej txheej ntawm cov khoom siv ceramic yog qhov nyuaj. Yuav ua li cas yog ceramic PCBs tsim? Txij li thaum cov ntaub ntawv ceramic tau siv los ua PCB substrate, ob peb txoj hauv kev tau tsim los tsim cov txheej txheem ntawm cov txheej txheem ceramic. Cov txheej txheem no yog HTCC, DBC, tuab zaj duab xis, LTCC, nyias zaj duab xis, thiab DPC.

HTCC

Pros: siab structural zog; siab thermal conductivity; zoo tshuaj stability; high hlau ceev; RoHS tau ntawv pov thawj

Cons: tsis zoo Circuit Court conductivity; siab sintering kub; kim kim

HTCC yog lub npe luv ntawm high-temperature co-fired ceramic. Nws yog qhov ntxov tshaj plaws ceramic PCB kev tsim khoom. Cov ntaub ntawv ceramic rau HTCC yog alumina, mullite, lossis txhuas nitride.

Nws txoj kev tsim khoom yog:

Ntawm 1300-1600 ℃, ceramic hmoov (tsis muaj iav ntxiv) yog sintered thiab qhuav kom khov. Yog hais tias tus tsim yuav tsum tau los ntawm lub qhov, qhov yog drilled ntawm lub substrate board.

Nyob rau tib lub kub kub, high-melting-temperature hlau yog melted raws li ib tug hlau muab tshuaj txhuam. Cov hlau tuaj yeem yog tungsten, molybdenum, molybdenum, manganese, thiab lwm yam. Cov hlau tuaj yeem yog tungsten, molybdenum, molybdenum, thiab manganese. Cov hlau muab tshuaj yog luam tawm raws li tus qauv tsim los tsim ib txheej txheej hauv Circuit Court substrate.

Tom ntej no, 4% -8% sintering pab ntxiv.

Yog hais tias PCB yog multilayer, txheej yog laminated.

Tom qab ntawd ntawm 1500-1600 ℃, tag nrho kev sib xyaw ua ke yog sintered los tsim cov ceramic Circuit Boards.

Thaum kawg, lub npog ntsej muag yog ntxiv los tiv thaiv txheej txheej hauv Circuit Court.

Thin Film Ceramic PCB Manufacturing

Pros: qis raug kub; zoo Circuit Court; zoo nto flatness

Cons: khoom kim heev raug; tsim tsis tau peb-dimensional circuits

Cov txheej tooj liab ntawm nyias zaj duab xis ceramic PCBs muaj thicknesses me dua 1 hli. Cov ntaub ntawv tseem ceeb ceramic rau nyias-film ceramic PCBs yog alumina thiab aluminium nitride. Nws txoj kev tsim khoom yog:

Ceramic substrate yog ntxuav ua ntej.

Nyob rau hauv lub tshuab nqus tsev, noo noo ntawm ceramic substrate yog thermally evaporated.

Tom ntej no, ib txheej tooj liab yog tsim rau ntawm ceramic substrate nto los ntawm magnetron sputtering.

Daim duab Circuit Court yog tsim los ntawm txheej tooj liab los ntawm lub teeb daj-lub teeb photoresist technology.

Tom qab ntawd cov tooj liab ntau dhau raug tshem tawm los ntawm etching.

Thaum kawg, lub npog ntsej muag yog ntxiv los tiv thaiv lub voj voog.

Cov ntsiab lus: cov zaj duab xis nyias ceramic PCB raug ua tiav hauv lub tshuab nqus tsev. Lub teeb daj lithography thev naus laus zis tso cai rau ntau qhov tseeb rau lub voj voog. Txawm li cas los xij, kev tsim zaj duab xis nyias nyias muaj qhov txwv rau tooj liab thickness. Nyias-film ceramic PCBs yog tsim rau high-precision ntim thiab cov khoom siv me me.

DPC

Pros: tsis txwv rau hom ceramic thiab thickness; zoo Circuit Court; qis raug kub; zoo nto flatness

Cons: kim khoom siv

DPC yog cov ntawv luv ntawm cov tooj liab ncaj qha. Nws tsim los ntawm nyias zaj duab xis ceramic tsim txoj kev thiab txhim kho los ntawm kev ntxiv cov tooj liab thickness los ntawm plating. Nws txoj kev tsim khoom yog:

Tib txheej txheem ntawm cov txheej txheem nyias-zaj duab xis tsim kom txog thaum cov duab hluav taws xob tau luam tawm ntawm cov yeeb yaj kiab tooj liab.

Lub Circuit Court tooj liab thickness yog ntxiv los ntawm plating.

Cov yeeb yaj kiab tooj liab raug tshem tawm.

Thaum kawg, lub npog ntsej muag yog ntxiv los tiv thaiv lub voj voog.

Kab lus no teev cov txheej txheem kev tsim khoom ceramic PCB. Nws qhia txog cov txheej txheem tsim khoom ntawm ceramic PCB thiab muab kev tshuaj xyuas luv luv ntawm cov txheej txheem. Yog tias cov engineers / daws cov tuam txhab / lub koom haum xav kom muaj cov khoom siv ceramics tsim thiab sib sau ua ke, YMSPCB yuav coj tau 100% txaus siab rau lawv.
