Multilayer Printed Circuit Boards

Printed Circuit Board (PCB), tseem hu ua Printed Circuit Board lossis Printed Circuit Board. Multilayer printed boards hais txog cov ntawv luam tawm uas muaj ntau tshaj ob txheej, uas yog tsim los ntawm kev sib txuas ntawm cov xov hlau ntawm ob peb txheej ntawm insulating substrates thiab cov ntaub qhwv siv los sib dhos thiab vuam cov khoom siv hluav taws xob. Lawv tsis tsuas yog muaj kev ua haujlwm ntawm kev ua lub voj voog ntawm txhua txheej, tab sis kuj muaj kev ua haujlwm ntawm kev sib nrig sib rwb thaiv tsev.

PCB multilayer board yog hais txog ntau txheej txheej Circuit Court board siv nyob rau hauv cov khoom siv hluav taws xob, uas siv ntau dua ib qho los yog ob-sided wiring boards. Lub rooj tsav xwm luam tawm uas siv ib txheej txheej ob sab hauv, ob sab ib sab txheej txheej, lossis ob txheej txheej sab hauv, thiab ob sab txheej txheej, thiab sib cuam tshuam nrog cov duab hluav taws xob raws li kev tsim qauv los ntawm kev tso chaw thiab insulating bonding cov ntaub ntawv, dhau los ua plaub los yog rau txheej luam tawm Circuit Board, tseem hu ua multi-layer printed circuit board.

Cov yam ntxwv ntawm PCB Multilayer Board

Qhov sib txawv loj tshaj plaws ntawm ntau txheej PCB pawg thawj coj saib thiab ib leeg lossis ob lub vaj huam sib luag yog qhov sib ntxiv ntawm cov txheej txheem hluav taws xob sab hauv (tswj cov txheej txheem hluav taws xob sab hauv) thiab txheej hauv av. Lub zog thiab hauv av network feem ntau yog xaim ntawm lub zog txheej. Txawm li cas los xij, cov txheej txheem txheej txheej txheej thaiv feem ntau yog ua raws li cov txheej txheem saum toj thiab hauv qab, ntxiv los ntawm cov txheej txheem nruab nrab. Yog li ntawd, txoj kev tsim ntawm ntau txheej boards yog qhov tseem ceeb ib yam li ntawm ob sab boards, thiab qhov tseem ceeb nyob rau hauv yuav ua li cas los txhim kho txoj hlua hluav taws xob hauv cov txheej txheem hluav taws xob kom ua kom cov xaim hluav taws xob ntawm lub rooj tsav xwm tsim nyog thiab zoo dua. electromagnetic compatibility.

Txheej txheem Flow ntawm PCB Multilayer Board

txheej txheem ntws

Printed Circuit Court board sab saum toj nrog cov duab ua tiav → acidic degreasing → scanning dej ntxuav → Secondary countercurrent dej ntxuav → micro etching → scanning dej ntxuav → Secondary countercurrent dej ntxuav → tooj liab plating prepreg → tooj liab plating → scanning dej ntxuav → tin plating prepreg → tin plating → Secondary countercurrent dej ntxuav → qis board

Qhov sib txawv ntawm ob tog PCB board thiab ib lub rooj tsavxwm PCB ib leeg yog tias tib lub vaj huam sib luag Circuit Court tsuas yog nyob rau ntawm ib sab ntawm PCB pawg thawj coj saib, thaum lub Circuit Court ntawm ob sab PCB board tuaj yeem txuas ntawm ob sab ntawm PCB pawg thawj coj saib nrog lub qhov hauv nruab nrab.
