Yuav ua li cas ua pcb resin plugging

Pcb resin plugging yog ib qho kev siv dav thiab nyiam cov txheej txheem nyob rau hauv xyoo tas los no, tshwj xeeb tshaj yog rau high-precision multilayer boards thiab cov khoom nrog cov thicknesses loj. Qee qhov teeb meem uas tsis tuaj yeem daws tau nrog cov roj ntsuab ntsaws qhov thiab nias-haum resin vam tias yuav daws tau los ntawm cov roj hmab ntsaws qhov. Vim yog cov yam ntxwv ntawm cov resin nws tus kheej, tib neeg tseem yuav tsum tau kov yeej ntau yam teeb meem hauv kev tsim cov khoom siv hluav taws xob hauv Circuit Court kom ua tau zoo ntawm cov resin plug qhov zoo dua.

1. Kev tsim cov txheej txheej sab nrauv ua tau raws li qhov yuav tsum tau ua ntawm cov yeeb yaj kiab tsis zoo, thiab cov thickness-inch ratio ntawm qhov los ntawm qhov yog tsawg dua los yog sib npaug rau 6: 1.

Cov xwm txheej uas yuav tsum tau ua kom tau raws li PCB tsis zoo zaj duab xis yuav tsum yog:

(1) Kab dav / kab sib txawv loj txaus

(2) Qhov siab tshaj plaws PTH qhov tsawg dua qhov siab tshaj plaws sealing muaj peev xwm ntawm cov zaj duab xis qhuav

(3) Lub thickness ntawm PCB yog tsawg tshaj li qhov siab tshaj plaws thickness xav tau los ntawm cov yeeb yaj kiab tsis zoo, thiab lwm yam.

(4) Cov Boards tsis muaj qhov tshwj xeeb, xws li: ib nrab electroplated kub board, electroplated npib tsib xee kub board, ib nrab-qhov board, luam plug board, ringless PTH qhov, board nrog PTH qhov, thiab lwm yam.

Kev tsim cov txheej txheej hauv PCB board → lamination → browning → laser drilling → debrowning → txheej txheej drilling → tooj liab sinking → tag nrho lub rooj tsavxwm qhov filling thiab electroplating → hlais tsom xam → txheej txheej qauv → txheej txheej acid etching → txheej txheej AOI → Ua raws txheej txheem ib txwm

2. Kev tsim cov txheej txheej sab nrauv ua tau raws li qhov yuav tsum tau ua ntawm cov yeeb yaj kiab tsis zoo, thiab cov thickness-inch ratio ntawm qhov los ntawm qhov yog ntau tshaj 6: 1.

Due to the thickness-to-diameter ratio of the through hole >6: 1, tooj liab thickness yuav tsum tau ntawm lub qhov los ntawm lub qhov tsis tuaj yeem ua tau raws li kev siv tag nrho lub rooj tsavxwm qhov-filling electroplating. Copper plating rau qhov yuav tsum tau muaj thickness, cov txheej txheem kev ua haujlwm tshwj xeeb yog raws li hauv qab no:

Kev tsim cov txheej sab hauv → lamination → browning → laser drilling → debrowning → txheej txheej drilling → tooj liab sinking → tag nrho lub rooj tsavxwm lub qhov filling thiab electroplating → tag nrho pawg thawj coj saib electroplating → hlais tsom xam → txheej txheej graphics → txheej txheej acid etching → ua raws li cov txheej txheem ib txwm

3. Cov txheej txheej sab nrauv tsis ua raws li qhov xav tau ntawm cov yeeb yaj kiab tsis zoo, txoj kab dav / kab sib txawv Ntau dua los yog sib npaug rau a, thiab txheej txheej txheej los ntawm qhov thickness-inch ratio Tsawg dua los yog sib npaug rau 6: 1.

Fabrication ntawm lub puab txheej ntawm lub rooj tsavxwm → lamination → browning → laser drilling → debrowning → txheej drilling → tooj liab sinking → tag nrho cov board filling thiab electroplating → hlais tsom xam → txheej txheej qauv → qauv plating → txheej txheej alkaline etching → Sab nrauv AOI → Ua raws -up li qub txheej txheem

Plaub: Cov txheej txheej sab nrauv tsis ua raws li qhov yuav tsum tau ua ntawm cov yeeb yaj kiab tsis zoo, kab dav / kab sib txawv 6:1.

Fabrication ntawm txheej sab hauv → nias → browning → laser drilling → debrowning → tooj liab sinking → tag nrho lub rooj tsavxwm qhov filling thiab electroplating → hlais tsom xam → tooj liab txo → txheej txheej drilling → tooj liab sinking → tag nrho board plating → txheej txheej graphics → qauv electroplating → txheej txheej alkaline etching → txheej txheej AOI → txheej txheem tom ntej

Pcb resin plug qhov txheej txheem ntau lawm: thawj zaug xyaum, ces phaj lub qhov los ntawm, ces ntsaws cov resin rau ci, thiab thaum kawg zom (soo). Cov polished resin tsis muaj tooj liab, thiab ib txheej ntawm tooj liab yuav tsum tau ntxiv kom tig mus rau hauv PAD. Cov kauj ruam no yog ua ua ntej thawj txheej txheem PCB drilling. Ua ntej, lub qhov ntawm lub fortress qhov yog ua tiav, thiab ces drilled. Rau lwm qhov, ua raws li cov txheej txheem qub qub.

Kev paub nthuav dav:

Thaum lub qhov ntsaws ntsaws tsis zoo thiab muaj cov npuas npuas hauv lub qhov, cov pa npuas yuav tuaj yeem tawg thaum lub rooj tsavxwm PCB hla ​​lub cub tawg vim nws yooj yim nqus dej. Hauv cov txheej txheem tsim khoom ntawm pcb resin plug qhov, yog tias muaj cua npuas hauv lub qhov, cov pa npuas no yuav tawm los ntawm cov resin thaum lub sij hawm ci, ua rau muaj qhov xwm txheej uas ib sab yog concave thiab ib sab yog protruding. Peb tuaj yeem kuaj xyuas cov khoom tsis raug no. Tau kawg, yog tias PCB pawg thawj coj saib uas nyuam qhuav tawm hauv lub Hoobkas tau ci thaum nws thauj khoom, yuav tsis muaj qhov tawg ntawm lub rooj tsavxwm feem ntau.
