Qhov ntau thiab tsawg ntawm ceramic circuit boards

Hauv tsab ntawv tshaj tawm no, peb yuav tshawb xyuas qhov ntau thiab tsawg thiab qhov ntev ntawm ceramic circuit boards.

Ceramic circuit boards tau dhau los ua neeg nyiam hauv kev lag luam hluav taws xob vim lawv cov yam ntxwv zoo thiab kev ua tau zoo piv rau cov PCBs (Printed Circuit Boards). Kuj tseem hu ua ceramic PCBs lossis ceramic substrates, cov laug cam no muaj kev tswj xyuas thermal zoo, muaj zog txhua yam thiab kev ua tau zoo ntawm hluav taws xob.

1. Txheej txheem cej luam ntawm ceramic circuit boards:

Ceramic circuit boards yog tsim los ntawm cov khoom siv ceramic xws li txhuas oxide (Al2O3) lossis silicon nitride (Si3N4) es tsis txhob siv cov khoom siv FR4 li niaj zaus siv hauv PCBs. Cov ntaub ntawv ceramic muaj cov thermal conductivity zoo dua thiab tuaj yeem ua kom cov cua sov los ntawm cov khoom siv rau ntawm lub rooj tsavxwm. Ceramic PCBs tau siv dav hauv cov ntawv thov uas xav tau lub zog siab thiab cov teeb liab siab, xws li hluav taws xob hluav taws xob, LED teeb pom kev zoo, aerospace thiab kev sib txuas lus.

2. Dimensions thiab qhov ntev ntawm ceramic circuit boards:

Ceramic Circuit Board qhov ntau thiab tsawg tuaj yeem sib txawv nyob ntawm cov ntawv thov tshwj xeeb thiab cov qauv tsim. Txawm li cas los xij, muaj qee qhov ntau thiab tsawg thiab qhov ntev uas feem ntau siv hauv kev lag luam. Cia peb nkag mus rau hauv cov ntsiab lus no:

2.1 Ntev, dav thiab thickness:
Ceramic circuit boards tuaj nyob rau hauv ntau qhov ntev, dav thiab thicknesses kom haum rau cov qauv sib txawv thiab kev siv. Qhov ntev ntev ntawm ob peb millimeters mus rau ob peb puas millimeters, thaum qhov dav tuaj yeem txawv ntawm ob peb millimeters mus rau kwv yees li 250 millimeters. Raws li rau lub thickness, nws yog feem ntau 0.25 hli mus rau 1.5 hli. Txawm li cas los xij, qhov loj me no tuaj yeem hloov kho kom tau raws li qhov kev xav tau tshwj xeeb.

2.2 Tus naj npawb ntawm cov khaubncaws sab nraud povtseg:
Tus naj npawb ntawm cov khaubncaws sab nraud povtseg hauv lub rooj tsavxwm ceramic txiav txim siab nws qhov nyuaj thiab kev ua haujlwm. Ceramic PCBs tuaj yeem muaj ntau txheej txheej, feem ntau ntawm ib leeg mus rau 6-txheej tsim. Ntau cov khaubncaws sab nraud povtseg tso cai rau kev sib koom ua ke ntawm cov khoom siv ntxiv thiab cov kab ke, uas ua kom yooj yim rau kev tsim hluav taws xob ntau.

2.3 Qhov Loj:
Ceramic PCBs txhawb qhov sib txawv aperture qhov ntau thiab tsawg nyob ntawm daim ntawv thov. Lub qhov tuaj yeem muab faib ua ob hom: plated los ntawm qhov (PTH) thiab tsis-plated los ntawm qhov (NPTH). Hom PTH qhov ntau thiab tsawg yog li ntawm 0.25 hli (10 mils) txog 1.0 hli (40 mils), thaum NPTH qhov ntau thiab tsawg tuaj yeem me me li 0.15 hli (6 mils).

2.4 Kab thiab qhov dav dav:
Cov kab thiab qhov dav dav hauv cov kab hluav taws xob ceramic ua lub luag haujlwm tseem ceeb hauv kev ua kom lub teeb pom kev zoo thiab kev ua haujlwm hluav taws xob. Cov kab kab dav dav dav li ntawm 0.10 hli (4 mils) txog 0.25 hli (10 mils) thiab sib txawv raws li qhov muaj peev xwm nqa tau tam sim no. Ib yam li ntawd, qhov sib txawv ntawm qhov sib txawv ntawm 0.10 hli (4 mils) thiab 0.25 hli (10 mils).

3. Qhov zoo ntawm ceramic circuit boards:

Nws yog ib qho tseem ceeb kom nkag siab txog qhov ntau thiab tsawg thiab qhov ntev ntawm cov khoom siv hluav taws xob ceramic, tab sis nws tseem ceeb sib npaug kom nkag siab txog qhov zoo uas lawv muab:

3.1 Thermal tswj:
Lub siab thermal conductivity ntawm cov ntaub ntawv ceramic ua kom muaj cua sov dissipation ntawm cov khoom siv hluav taws xob, yog li ua kom tag nrho cov kev ntseeg tau.

3.2 Mechanical zog:
Ceramic circuit boards muaj lub zog zoo heev, ua rau lawv tiv taus ntau yam sab nraud xws li kev co, kev poob siab thiab ib puag ncig.

3.3 Kev ua haujlwm hluav taws xob:
Ceramic PCBs muaj qhov tsis tshua muaj dielectric poob thiab tsis tshua muaj teeb liab poob, ua kom muaj kev ua haujlwm siab thiab txhim kho cov teeb liab kev ntseeg siab.

3.4 Miniaturization thiab high-density tsim:
Vim lawv qhov me me thiab zoo thermal zog, ceramic circuit boards pab miniaturization thiab high-density designs thaum tuav tswj hluav taws xob zoo heev.

4. Nyob rau hauv xaus:

Qhov ntau thiab tsawg thiab qhov ntev ntawm ceramic circuit boards txawv nyob ntawm daim ntawv thov thiab cov qauv tsim. Lawv qhov ntev thiab dav ntawm ob peb millimeters mus rau ob peb puas millimeters, thiab lawv cov tuab yog li ntawm 0.25 hli mus rau 1.5 hli. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg, qhov loj me, thiab cov kab dav dav kuj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab kev ua haujlwm thiab kev ua haujlwm ntawm ceramic PCBs. Kev nkag siab txog qhov loj me no yog qhov tseem ceeb rau kev tsim thiab siv cov tshuab hluav taws xob zoo uas siv cov khoom siv hluav taws xob ceramic.
