Multilayer boards siv ntau dua ib leeg los yog ob tog thaiv kab thaiv. Lub rooj tsav xwm luam tawm nrog ib qho ob sab raws li cov txheej sab hauv thiab ob sab ib leeg raws li txheej txheej, los yog ob sab ob sab raws li txheej sab hauv thiab ob sab ib leeg raws li txheej txheej, sib txuas los ntawm qhov chaw thiab ib qho Insulating adhesive khoom Ua ke, cov qauv kev sib txuas yog sib txuas ua ke raws li cov qauv tsim kom dhau los ua plaub-txheej thiab rau-txheej luam ntawv Circuit Court boards, tseem hu ua multi-layer printed circuit boards.

Multilayer PCB board ntau lawm txheej txheem

1. Kev xaiv cov khoom siv

Nrog rau kev txhim kho cov khoom siv hluav taws xob ua tau zoo thiab muaj ntau yam khoom siv hluav taws xob, nrog rau cov khoom siv hluav taws xob ntau zaus thiab kev kub ceev, cov khoom siv hluav taws xob hauv hluav taws xob yuav tsum muaj qhov tsis tshua muaj hluav taws xob tsis tu ncua thiab dielectric poob, nrog rau CTE tsawg thiab nqus dej tsawg. . tus nqi thiab zoo dua cov ntaub ntawv CCL kom ua tau raws li kev ua thiab kev ntseeg tau ntawm cov rooj tog siab.

2. Laminated qauv tsim

Cov ntsiab lus tseem ceeb hauv kev tsim cov qauv laminated yog cov cua kub tsis kam, tiv taus hluav taws xob, cov kua nplaum filling thiab thickness ntawm dielectric txheej, thiab lwm yam. Cov ntsiab lus hauv qab no yuav tsum ua raws li:

(1) Lub prepreg thiab core board manufacturers yuav tsum sib xws.

(2) Thaum tus neeg siv khoom xav tau daim ntawv TG siab, lub rooj tsav xwm tseem ceeb thiab cov prepreg yuav tsum siv cov khoom siv siab TG sib xws.

(3) Sab hauv txheej substrate yog 3OZ lossis siab dua, thiab cov prepreg nrog cov ntsiab lus siab resin raug xaiv.

(4) Yog tias tus neeg siv khoom tsis muaj qhov tshwj xeeb yuav tsum tau ua, lub thickness kam rau ua ntawm lub interlayer dielectric txheej feem ntau tswj los ntawm ntxiv /-10 feem pua. Rau cov phaj impedance, dielectric thickness kam rau ua yog tswj los ntawm IPC -4101 C / M chav kawm kam rau ua.

3. Interlayer alignment tswj

Qhov tseeb ntawm qhov loj me me ntawm cov txheej txheej hauv cov tub ntxhais lub rooj tsavxwm thiab kev tswj ntawm qhov loj me yuav tsum tau them nyiaj kom raug rau cov duab loj ntawm txhua txheej ntawm lub rooj tsavxwm siab los ntawm cov ntaub ntawv khaws cia hauv kev tsim khoom thiab kev paub txog cov ntaub ntawv keeb kwm rau ib lub sij hawm ntawm lub sij hawm, thiaj li ua kom lub expansion thiab contraction ntawm lub core board ntawm txhua txheej. sib xws.

4. Sab hauv txheej txheej txheej tshuab

Rau kev tsim cov boards siab, lub laser direct imaging tshuab (LDI) tuaj yeem qhia tau los txhim kho cov duab tsom xam muaj peev xwm. Txhawm rau txhim kho txoj kab etching muaj peev xwm, nws yog ib qho tsim nyog yuav tsum tau them nyiaj tsim nyog rau qhov dav ntawm txoj kab thiab lub ncoo hauv kev tsim qauv engineering, thiab paub meej tias qhov kev tsim kho ntawm cov txheej txheej sab hauv kab dav, kab sib nrug, kev sib cais lub nplhaib loj, txoj kab ywj pheej, thiab qhov deb-rau-kab deb yog tsim nyog, txwv tsis pub hloov engineering tsim.

5. Nias txheej txheem

Tam sim no, interlayer positioning txoj kev ua ntej lamination mas muaj xws li: plaub-qhov chaw (Pin LAM), kub yaj, rivet, kub yaj thiab rivet ua ke. Cov khoom sib txawv siv cov txheej txheem sib txawv.

6. Drilling txheej txheem

Vim lub superposition ntawm txhua txheej, lub phaj thiab tooj liab txheej yog super tuab, uas yuav hnav lub laum me ntsis thiab yooj yim tawg lub laum hniav. Tus naj npawb ntawm qhov, poob ceev thiab kev sib hloov ceev yuav tsum tau kho kom haum.

Qhov txawv ntawm multi-layer circuit board thiab double-sided board:

1. Ib txheej txheej pcb Circuit Court board yog ib lub rooj tsav xwm luam tawm uas yog laminated thiab sib koom ua ke los ntawm kev sib hloov cov qauv txheej txheej thiab cov ntaub ntawv insulating. Tus naj npawb ntawm cov txheej txheem conductive yog ntau tshaj peb, thiab cov hluav taws xob sib cuam tshuam ntawm cov txheej yog pom tau los ntawm qhov metallized qhov.

2. Sib piv cov txheej txheem ntau lawm ntawm ob tog, lub rooj tsavxwm multilayer ntxiv ntau cov txheej txheem xws li txheej txheej txheej txheej, blackening, lamination, etchback thiab decontamination.

3. Multi-layer boards yog nruj dua ob-sided boards nyob rau hauv cov nqe lus ntawm tej yam txheej txheem tsis, khoom raug thiab complexity. Piv txwv li, qhov yuav tsum tau ua kom zoo rau lub qhov phab ntsa ntawm lub rooj tsavxwm ntau txheej yog nruj dua li ntawm ob txheej txheej board, yog li qhov yuav tsum tau ua rau drilling ntau dua.

4. Tus naj npawb ntawm pawg ib qho drilling, qhov kev sib hloov ceev thiab pub ntawm lub laum me ntsis txawv ntawm cov khoom ntawm ob sab ntawm lub rooj tsavxwm.

5. Kev tshuaj xyuas cov khoom tiav thiab ib nrab ntawm cov txheej txheem ntau lawm kuj tseem nruj dua thiab nyuaj dua li ntawm ob sab boards.

6. Vim yog cov txheej txheem nyuaj ntawm cov txheej txheem ntau txheej, cov txheej txheem glycerin kub-kua tau txais yuav; infrared kub-melt txheej txheem uas yuav ua rau lub zos kub nce yog tsis siv.
