Khoom piav qhia

8OZ DPC ceramic board Stackup

Qhov no yog 8OZ DPC ceramic board stackup. Tag nrho cov tuab yog 0.9 hli, thiab cov txheej sab saum toj thiab hauv qab txheej tooj liab thickness yog 280um. Lub board nto yog ENIG. DPC ceramic circuit board hais txog tooj liab-plated ceramic circuit board. Nws yog ib hom tshiab ntawm ceramic circuit board. Piv nrog rau cov tsoos PCB (lub rooj tsavxwm luam tawm), nws muaj kev ntseeg siab dua, kev ua haujlwm zoo dua thiab ntau dua thermal expansion coefficient thiab lwm yam zoo.

8OZ DPC ceramic board Qhov zoo
DPC ceramic substrate nta: siab thermal conductivity, siab rwb thaiv tsev, siab Circuit Court daws teeb meem, siab nto flatness, thiab siab kub-ceramic bonding zog.

• DPC ceramic substrate kuj muaj ntau yam zoo
• Kev sib txuas lus tsawg tsawg - qhov dielectric tas li ntawm cov khoom siv ceramic nws tus kheej ua rau lub teeb liab poob me me.
• High thermal conductivity - thermal conductivity ntawm alumina ceramics yog 15 ~ 35w / mk, thiab thermal conductivity ntawm aluminium nitride ceramics yog 170 ~ 230w / mk.
• Ntau qhov sib piv thermal expansion coefficient - cov khoom ntawm cov nti feem ntau yog Si (silicon) GaAS (galium arsenide). Lub thermal expansion coefficients ntawm ceramics thiab chips yog nyob ze. Thaum qhov kub sib txawv hloov pauv loj heev, yuav tsis muaj deformation ntau dhau, ua rau cov hlau desoldering thiab kev ntxhov siab sab hauv. Thiab lwm yam teeb meem.
• Lub zog sib txuas siab - Cov khoom siv plaub-txoj kev ceramic Circuit Board muaj lub zog sib txuas siab ntawm cov hlau txheej thiab ceramic substrate, txog li 45MPa (lub zog ntawm cov ntawv ceramic nrog lub thickness ntau dua 1mm).
• Ntshiab tooj liab dhau-qhov-pob zeb ceramic DPC txheej txheem txhawb PTH / Vias.
• Kev khiav hauj lwm kub - Ceramics tuaj yeem tiv taus qhov hloov pauv siab thiab qis qis, thiab tuaj yeem ua haujlwm ib txwm nyob rau qhov kub siab txog 600 degrees.
• High hluav taws xob rwb thaiv tsev - cov ntaub ntawv ceramic lawv tus kheej yog cov ntaub ntawv insulating thiab muaj peev xwm tiv taus siab tawg voltages.
• Cov kev pabcuam customized - Beton tuaj yeem muab cov kev pabcuam customized raws li cov neeg siv khoom xav tau, thiab ua haujlwm ntau raws li cov khoom tsim duab kos duab (Gerber file thiab Parameter file) thiab cov kev cai muab los ntawm tus neeg siv. Cov neeg siv muaj kev xaiv ntau dua thiab siv tau ntau dua.

DPC txheej txheem hauv Ceramic PCB Manufacturing
Ua ntej, lub laser yog siv los npaj los ntawm qhov ntawm cov ceramic substrate (qhov aperture feem ntau yog 60μm ~ 120μm), thiab tom qab ntawd ultrasonic tsis siv los ntxuav cov ceramic substrate; magnetron sputtering thev naus laus zis yog siv los tso cov txheej txheem hlau (Ti / Cu phiaj) rau saum npoo ntawm cov khoom siv ceramic. Tom qab ntawd, cov txheej txheem tsim hluav taws xob tau ua tiav los ntawm photolithography thiab kev txhim kho; electroplating yog siv los sau cov voids thiab thicken cov hlau Circuit Court txheej, thiab kev kho deg yog siv los txhim kho cov solderability thiab oxidation tsis kam ntawm substrate. Thaum kawg, cov zaj duab xis qhuav raug tshem tawm thiab cov noob txheej yog etched kom tiav cov substrate npaj.

Daim duab hauv qab no piav qhia luv luv txog cov txheej txheem DPC hauv ceramic PCB manufacturing. Lub high-frequency dielectric tsis tu ncua thiab poob qhov tseem ceeb yog muab rho tawm siv cov khoom hluav taws xob yooj yim ntawm DPC substrate.
