Qhov sib txawv ntawm ceramic Circuit Board tsim

Nyob rau hauv no blog ncej, peb yuav tshawb txog ntau hom ceramic Circuit Board tsim thiab lawv cov yam ntxwv tshwj xeeb.

Ceramic circuit boards tau dhau los ua neeg nyiam vim lawv muaj ntau yam zoo dua li cov khoom siv hluav taws xob xws li FR4 lossis polyimide. Ceramic circuit boards tau dhau los ua thawj qhov kev xaiv rau ntau daim ntawv thov vim lawv cov thermal conductivity zoo, kub tsis kam thiab zoo txhua yam muaj zog. Raws li kev thov nce, yog li ntau yam ntawm cov khoom siv hluav taws xob ceramic tsim muaj nyob hauv khw.

1. Alumina-raws li ceramic Circuit Board:

Aluminium oxide, tseem hu ua aluminium oxide, yog cov khoom siv dav siv hauv cov laug cam. Nws muaj cov khoom siv hluav taws xob zoo heev thiab tsim nyog rau cov ntawv thov uas xav tau lub zog dielectric siab. Alumina ceramic circuit boards tuaj yeem tiv taus qhov kub thiab txias, ua rau lawv tsim nyog siv rau hauv cov ntawv siv hluav taws xob siab xws li hluav taws xob hluav taws xob thiab tshuab tsheb. Nws du nto tiav thiab qis coefficient ntawm thermal expansion ua rau nws zoo tagnrho rau cov ntawv thov uas muaj kev tswj xyuas thermal.

2. Aluminium nitride (AlN) ceramic circuit board:

Aluminium nitride ceramic circuit boards muaj superior thermal conductivity piv rau alumina substrates. Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau ua kom muaj cua sov zoo, xws li LED teeb pom kev zoo, lub zog hluav taws xob, thiab cov khoom siv RF/microwave. Aluminium nitride circuit boards ua tau zoo hauv kev siv ntau zaus vim lawv qhov tsis tshua muaj dielectric poob thiab zoo heev teeb liab kev ncaj ncees. Tsis tas li ntawd, AlN circuit boards yog lub teeb yuag thiab ib puag ncig tus phooj ywg, ua rau lawv xaiv rau ntau yam lag luam.

3. Silicon nitride (Si3N4) ceramic circuit board:

Silicon nitride ceramic circuit boards paub txog lawv cov khoom siv zoo heev thiab thermal shock resistance. Cov vaj huam sib luag no feem ntau yog siv rau hauv qhov chaw hnyav uas qhov kub thiab txias hloov pauv, kev kub ntxhov siab, thiab muaj cov khoom corrosive. Si3N4 circuit boards pom cov ntawv thov hauv kev lag luam xws li aerospace, tiv thaiv, thiab roj thiab roj, qhov kev ntseeg siab thiab kav ntev yog qhov tseem ceeb. Tsis tas li ntawd, silicon nitride muaj cov khoom siv hluav taws xob zoo, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hluav taws xob siab.

4. LTCC (tsis tshua muaj kub co-fired ceramic) Circuit Court board:

LTCC Circuit Court boards yog tsim los siv multilayer ceramic tapes uas yog tshuaj ntsuam-luam nrog cov qauv conductive. Cov khaubncaws sab nraud povtseg thiab tom qab ntawd raug rho tawm haujlwm ntawm qhov kub thiab txias, tsim kom muaj lub rooj tsav xwm zoo heev thiab txhim khu kev qha. LTCC thev naus laus zis tso cai rau cov khoom siv tsis zoo xws li cov resistors, capacitors thiab inductors ua ke nyob rau hauv Circuit Court board nws tus kheej, tso cai rau miniaturization thiab txhim kho kev ua tau zoo. Cov boards no tsim nyog rau kev sib txuas lus wireless, automotive electronics, thiab cov khoom siv kho mob.

5. HTCC (siab kub co-fired ceramic) Circuit Court board:

HTCC circuit boards zoo ib yam li LTCC boards nyob rau hauv cov nqe lus ntawm kev tsim khoom. Txawm li cas los xij, HTCC cov laug cam raug rho tawm haujlwm ntawm qhov kub siab dua, ua rau muaj zog ua kom muaj zog thiab ua haujlwm siab dua. Cov laug cam no feem ntau yog siv rau hauv cov ntawv thov kub xws li tsheb sensors, aerospace electronics, thiab downhole drilling cuab yeej. HTCC circuit boards muaj thermal stability zoo heev thiab tuaj yeem tiv taus qhov kub thiab txias.

Hauv cov ntsiab lus

Ntau hom ceramic circuit boards yog tsim los ua kom tau raws li ntau yam kev xav tau ntawm kev lag luam. Txawm hais tias nws yog cov ntawv siv hluav taws xob siab, kev siv hluav taws xob zoo, kev kub ntxhov ib puag ncig lossis kev xav tau me me, cov qauv tsim hluav taws xob ceramic tuaj yeem ua tau raws li cov cai no. Raws li kev siv thev naus laus zis txuas ntxiv mus, cov kab hluav taws xob ceramic yuav tsum ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuab hluav taws xob tshiab thiab txhim khu kev qha thoob plaws kev lag luam.
