Txhawm rau txhim kho kev ua haujlwm ntau lawm thiab txo cov nqi tsim khoom hauvPCB sib dhostxheej txheem, liab qab Circuit Court boards feem ntau ua nyob rau hauv vaj huam sib luag rau ntau lawm, uas yuav pab tau PCBA ua cov nroj tsuag mus nqa tawm chip vuam.Cov hauv qab no yuav tham txog cov txheej txheem panelized thiab cov hauv paus ntsiab lus ntawm Circuit Board.
Lub hauv paus ntsiab lus ntawm PCB panelization:
1. Qhov loj ntawm PCB vaj huam sib luag board dav ≤ 300mm (Fuji kab);Yog tias xav tau kev xa tawm tsis siv neeg, qhov loj ntawm PCB yuav tsum ≤ 125mm (W) × 180mm (L).
2. Cov duab ntawm PCB yuav tsum nyob ze rau lub xwmfab kom deb li deb tau, thiab pom zoo rau lub rooj tsavxwm splicing yog (2 * 2, 3 * 3, 4 * 4) nyob rau hauv txhua lub vaj huam sib luag.
3. Cov txheej txheem sab nrauv (clamping edge) ntawm lub rooj tsav xwm Circuit Court yuav tsum tau txais kev kaw-voj tsim los xyuas kom meej tias lub vaj huam sib luag PCB yuav tsis deform tom qab nws tau kho ntawm lub fixture.
4. Qhov me me PCB board chaw nyob deb yuav tsum tau tswj nyob rau hauv 75mm ~ 145mm.
5. Yuav tsum tsis muaj cov khoom siv loj lossis cov khoom siv tawm ze ze ntawm qhov chaw sib txuas ntawm lub thav duab sab nraud ntawm lub rooj sib txuas ntawm lub rooj tsavxwm thiab lub rooj tsavxwm me me, thiab yuav tsum muaj qhov chaw siab tshaj 0.5 hli ntawm cov khoom thiab cov ntug ntawm PCB board rau xyuas kom lub cev ua haujlwm ntawm cov cuab yeej txiav.
6. Ntawm plaub lub kaum sab xis ntawm PCB lub thav duab sab nrauv, plaub qhov chaw qhib tau qhib thiab lub qhov taub yog (4mm ± 0.01mm);Lub zog ntawm lub qhov yuav tsum yog nruab nrab los xyuas kom meej tias nws yuav tsis tawg thaum lub sij hawm tus txheej txheem ntawm loader thiab unloader;Lub qhov taub thiab qhov tseeb ntawm qhov chaw yuav tsum siab, thiab lub qhov yuav tsum du.
7. Txhua lub rooj tsav xwm me me hauv PCB yuav tsum muaj tsawg kawg yog peb qhov chaw nyob, 3 ≤ lub qhov taub ≤ 6mm, thiab tsis pub xaim lossis SMT tsis pub dhau 1 hli ntawm ntug qhov chaw.
8. Thaum teeb tsa qhov taw qhia qhov chaw siv, qhov chaw tsis muaj zog vuam 1.5 hli loj dua qhov chaw taw tes yog feem ntau tshwj tseg nyob ib ncig ntawm qhov chaw.
9. Cov khoom loj loj yuav tsum tau muab nrog rau qhov chaw ua haujlwm lossis qhov chaw, xws li: microphone, roj teeb interface, microswitch, headset interface, lub cev muaj zog, thiab lwm yam.
Kev sib txuas ntawm PCB txoj hauv kev hauv vaj huam sib luag:
1. V-CUT
V-CUT txhais tau hais tias ob peb lub rooj tsavxwm lossis tib lub rooj tsavxwm tuaj yeem ua ke thiab sib txuas ua ke, thiab tom qab ntawd V-groove tuaj yeem txiav nrog lub tshuab V-CUT ntawm cov laug cam tom qab ua tiav PCB, uas tuaj yeem tawg thaum siv.Nws yog ib txoj kev nrov dua niaj hnub no.
2. Punching zawj
Punching yog hais txog milling khoob ntawm daim hlau lossis hauv daim hlau nrog lub tshuab milling raws li qhov xav tau, uas yog sib npaug rau kev khawb tawm.
3. Stamp qhov
Qhov no txhais tau hais tias siv lub qhov me me los txuas rau PCB pawg thawj coj saib, uas zoo li cov duab sawtooth ntawm lub stamp, yog li nws yog hu ua stamp qhov txuas.Lub qhov txuas qhov txuas yuav tsum muaj kev tswj xyuas siab nyob ib puag ncig ntawm lub rooj tsavxwm, uas tsuas yog lub qhov me me tuaj yeem siv los hloov V kab.
