- Thick Film Ceramic PCB: Siv cov tshuaj ntsuam - luam tawm tuab - zaj duab xis neeg xyuas pib muab tshuaj txhuam, sintered los ua cov voj voog. Resistant mus rau qhov kub thiab corrosion, haum rau siab - daim ntawv thov kev ntseeg siab.
- Ib sab ceramic PCB vs. Multilayer ceramic PCB: Ib leeg-sided boards muab cov qauv yooj yim thiab tus nqi qis dua; multilayer designs ua kom muaj kev sib txuas ntau dua, feem ntau siv hauv high-end power modules.
Hauv qee qhov kev tsim hluav taws xob siab -, ceramic substrates tau ua ke nrog cov txheej txheem tooj liab hnyav pcb, nce tooj liab tuab (piv txwv li, 3 oz-10 oz) txhawm rau txhim kho lub peev xwm tam sim no thiab cua sov.
Cov txheej txheem tsim khoom thiab kev ua tau zoo
Ceramic PCB boards tuaj yeem tsim siv ntau yam txheej txheem, txhua qhov haum rau qhov sib txawv thickness, precision, thiab cov nqi yuav tsum tau ua
DPC (Direct Plated tooj liab)

Sintered ntawm 1600-1700 degree, haum rau siab -kub ib puag ncig.
04
Thick Film Txheej txheem
Printing conductor / dielectric txheej ntawm ceramic substrate, ces sintering ntawm qhov kub thiab txias.
05
Core Performance Advantages
- High thermal conductivity (25–330 W/m·K), deb tshaj FR-4 (kwv yees . 0.8–1 W/m·K)
- Tsawg thermal expansion coefficient, txo qhov sib koom ua ke qaug zog los ntawm thermal cycling
- Cov rwb thaiv tsev zoo heev, tiv thaiv cov khoom los ntawm kev puas tsuaj thaum tshav kub kub
- Corrosion thiab siab -kub tsis kam, ua haujlwm ruaj khov mus txog 800 degree
- tuaj yeem ua ke nrog Thick Copper PCB thev naus laus zis los ua kom muaj zog ceev thiab kev ntseeg tau
Tej kev siv
- Lub hwj chim hluav taws xob: IGBT modules, MOSFET tsav tsheb boards, inverters, thiab lwm yam siab -power modules
- LED teeb pom kev zoo: Siab-lub zog LED substrates kom ntev lub teeb ci lub neej
- RF/microwave: Kav hlau txais xov arrays, fais fab amplifier modules
- Automotive electronics: Cov tswj lub cev muaj zog, lub tsheb radar, lub zog tsav tsheb modules
- Cov cuab yeej kho mob: High-cov duab kos duab, cov ntawv tsav tsheb laser
Hauv cov ntawv thov no, kev sib txuas Ceramic PCBs nrog Hnyav Copper Circuit Board thev naus laus zis tuaj yeem txhim kho cov txheej txheem thermal tswj thiab hluav taws xob ruaj ntseg, txuas ntxiv lub neej ntawm cov cuab yeej.
Kev tsim thiab kev tsim khoom xav tau
- Sib piv tooj liab thickness thiab kab dav kom sib npaug tam sim no muaj peev xwm thiab kub dissipation
- High thermal conductivity materials (eg, AlN, BeO) suit high-power density and high-frequency applications, but require cost trade-offs
- Interlayer kev sib txuas hauv multilayer ceramic PCBs xav tau kev tswj xyuas meej ntawm sintering shrinkage
- Hauv siab -tam sim no tsim, kev koom ua ke Heavy Copper PCB txheej txheem tuaj yeem txhim kho kev ntseeg tau ntxiv
- Tus account rau lub brittleness ntawm ceramics nyob rau hauv board puab thiab mounting tsim
Cov ntsiab lus
Txawm hais tias nws yog ceramic substrate PCB lossis alumina ceramic PCB, tus nqi tseem ceeb ntawm lub rooj tsav xwm ceramic yog nyob rau hauv kev muab kev txhawb nqa lub cev thiab hluav taws xob muaj zog rau cov kub kub flux, siab - zaus, thiab siab - daim ntawv thov kev ntseeg siab. Rau engineering tej yaam num thawb kev txwv kev ua tau zoo, lub rooj tsavxwm ceramic tsis yog ib qho kev xaiv khoom siv xwb- nws yog ib qho tseem ceeb hauv kev ruaj ntseg.
Shenzhen STHL Technology Co., Ltd. muaj kev paub dhau los hauv ceramic PCB thiab Heavy Copper PCB kev tsim khoom, muab ib qho - nres kev daws teeb meem los ntawm kev xaiv cov khoom siv thiab cov qauv tsim rau kev tsim khoom loj, pab koj cov khoom zoo hauv siab - lub zog, siab - kev lag luam kev ntseeg siab.
