Yuav ua li cas Beton ua hauj lwm tawm cov teeb meem tsim nyob rau hauv FR4 PCB?

-Qhov Kev Npaj

Tshem tawm cov khib nyiab kom zoo & kho lub tshuab laum tsis zoo: ua ntej plating nrog tooj liab, Beton them siab rau txhua qhov ntawm fr4 pcb kho kom tshem tawm cov khib nyiab, qhov tsis sib xws, thiab epoxy smear, lub qhov huv si xyuas kom cov plating ua tiav cov phab ntsa ntawm lub qhov. . kuj, thaum ntxov ntawm cov txheej txheem, laum tshuab tsis tau kho kom raug.

- Kev Npaj Nto

Deburring ua tib zoo: peb cov neeg ua haujlwm paub txog technology yuav paub ua ntej tias tib txoj hauv kev kom tsis txhob muaj qhov tshwm sim tsis zoo yog xav tias yuav tsum muaj kev tuav tshwj xeeb thiab ua cov kauj ruam tsim nyog kom paub tseeb tias cov txheej txheem ua tib zoo thiab raug.

-Cov nqi nthuav dav

kev cai rau kev soj ntsuam nrog ntau yam ntaub ntawv, Beton yuav tuaj yeem txheeb xyuas qhov sib xyaw ua ke kom paub tseeb tias nws tsim nyog. tom qab ntawd ua kom lub sij hawm ntev kev cia siab ntawm cte (coefficient ntawm thermal expansion), nrog rau qis cte, qhov tsawg dua cov plated los ntawm qhov yuav ua tsis tiav los ntawm kev rov flexing ntawm tooj liab uas ua rau cov txheej txheem sab hauv.

-Scaling

Beton tswj lub circuitry yog scaled-up los ntawm paub feem pua ​​nyob rau hauv kev cia siab ntawm qhov kev poob no kom cov khaubncaws sab nraud povtseg yuav rov qab mus rau lawv raws li-tsim qhov ntev tom qab lub lamination voj voog tiav. kuj, siv lub laminate chaw tsim tshuaj paus lub hauv paus scaling cov lus pom zoo nyob rau hauv ua ke nrog nyob rau hauv lub tsev statistical txheej txheem tswj cov ntaub ntawv, mus rau dial-nyob rau hauv scale yam uas yuav zoo ib yam nyob rau hauv lub sij hawm nyob rau hauv lub chaw tsim khoom tshwj xeeb.

-Machining

Thaum lub sijhawm los tsim koj lub pcb, Beton nco ntsoov tias koj xaiv muaj cov cuab yeej zoo thiab kev paub los tsim nws kom raug ntawm thawj zaug sim.

Ntim & Xa

Beton tsis yog tsuas yog sim muab cov khoom lag luam zoo rau cov neeg siv khoom xwb, tab sis kuj tseem ua tib zoo saib xyuas cov khoom tiav thiab muaj kev nyab xeeb. Tsis tas li, peb npaj qee qhov kev pabcuam tus kheej rau txhua qhov kev txiav txim.

-Cov khoom ntim:

PCB: kaw lub hnab, Anti-static hnab, haum thawv.

PCBA: Anti-static ua npuas ncauj hnab, Anti-static hnab, haum thawv.

Customized Ntim: Lub thawv sab nraud yuav luam tawm lub npe ntawm tus neeg siv khoom chaw nyob, cim, tus neeg siv khoom xav tau qhia qhov chaw thiab lwm yam ntaub ntawv.

FR txhais tau hais tias "flame-retardant," FR -4 (los yog FR4) yog qib NEMA rau cov khoom siv iav-reinforced epoxy laminate, cov khoom sib xyaw ua ke ntawm cov ntaub fiberglass nrog cov epoxy resin binder uas ua rau nws zoo tagnrho substrate. rau cov khoom siv hluav taws xob ntawm lub rooj tsav xwm luam tawm.

MultiLayer PCB yog dab tsi

Multi-Layer PCB xa mus rau lub rooj tsav xwm luam tawm muaj ntau tshaj li ob txheej tooj liab, xws li 4L, 6L, 8L, 10L, 12L, thiab lwm yam. Raws li kev txhim kho thev naus laus zis, tib neeg tuaj yeem tso ntau thiab ntau txheej tooj liab rau tib lub rooj tsavxwm. Tam sim no, peb tuaj yeem tsim 20L-32L FR4 PCB.

Los ntawm cov qauv no, tus kws tshaj lij tuaj yeem muab cov kab sib txawv ntawm cov txheej txheem sib txawv, xws li cov txheej txheem rau lub zog, kev xa cov teeb liab, rau EMI shielding, rau cov khoom sib dhos, thiab lwm yam. Txhawm rau kom tsis txhob muaj ntau txheej txheej, Buried Via lossis Dig Muag ntawm yuav raug tsim los ntawm ntau txheej PCB. Rau board ntau tshaj 8 txheej, siab Tg FR4 cov khoom yuav nrov tshaj li ib txwm Tg FR4.

Ntau cov khaubncaws sab nraud povtseg nws yog, ntau qhov nyuaj & nyuaj kev tsim khoom yuav yog, thiab tus nqi kim dua yuav yog.

Qhov zoo ntawm kev siv MultiLayer PCB

1. Haum rau kev tsim qauv
Cov khoom siv nyuaj nrog ntau cov khoom siv thiab cov khoom siv hluav taws xob tau txais txiaj ntsig los ntawm kev siv ntau txheej PCBs. Cov cuab yeej siv nrog ntau yam kev siv thiab cov yam ntxwv siab heev xav tau qhov nyuaj no. Ntau ntau txheej PCB boards kuj muaj kev ua haujlwm xws li kev tswj xyuas impedance thiab electromagnetic cuam tshuam shielding, uas ntxiv txhim kho qhov zoo ntawm PCB boards thiab khoom siv.

2. Lub zog loj
Vim lub siab ceev Circuit Court, lub rooj tsav xwm Circuit Court kuj muaj zog dua. Qhov no txhais tau hais tias lawv muab kev ua haujlwm siab thiab ceev, ua rau lawv tshwj xeeb rau cov khoom siv siab heev.

3. Cov khoom siv ruaj khov heev
Raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg, thicker boards yog ntau ruaj. Yog li ntawd, nws tuaj yeem tiv taus qhov mob hnyav dua.

4. Me me thiab lub teeb-yuag
Qhov loj me thiab lub teeb yuag yog cov yam ntxwv ntxiv ntawm multilayer boards. Qhov no ua rau lawv zoo tagnrho rau cov khoom siv miniaturization.

5. Ib qho chaw sib txuas
Hais txog kev tsim qauv yooj yim thiab qhov hnyav, qhov tseeb tias multilayer pcb board ua haujlwm nrog ib qho kev sib txuas lus yog ib qho txiaj ntsig ntxiv.

Qhov zoo ntawm FR4 PCB

FR-4 cov ntaub ntawv yog nrov heev vim nws muaj ntau yam zoo kawg nkaus uas yuav pab tau enig pcb luam ntawv Circuit Court boards. Ntxiv rau qhov pheej yig thiab yooj yim ua haujlwm nrog, nws yog ib qho hluav taws xob insulator nrog lub zog dielectric siab heev. Tsis tas li ntawd, nws yog ruaj, noo-resistant, kub-resistant thiab hnav.

FR-4 yog cov khoom siv dav dav, feem ntau nrov rau nws cov nqi qis thiab txheeb ze txhua yam thiab hluav taws xob stability. Thaum cov khoom no muaj cov txiaj ntsig zoo thiab muaj nyob rau hauv ntau yam thicknesses thiab ntau thiab tsawg.
