Dab tsi yog cov yam ntxwv ntawm ob chav txheej pcb board thiab ntau txheej txheej pawg thawj coj saib thiab yuav ua li cas paub qhov txawv lawv? Cia ua raws li pcb pawg xa khoomkom nkag siab:

Ob chav txheej pcb board

Ob tog ob tog tsav tau muaj xaim ntawm ob sab.Tab sis siv ob tog ntawm cov xov hlau, yuav tsum muaj hluav taws xob sib txuas zoo ntawm ob tog.Qhov no "choj" ntawm cov xov hluav taws xob yog hu ua lub qhov qhia (VIA) .A phau qhia lub qhov yog lub qhov me me hauv PCB, uas muaj txhij lossis txheej nrog cov hlau, uas tuaj yeem txuas nrog cov xaim ntawm ob sab. Vim tias ob lub vaj huam sib luag muaj ob zaug ntawm thaj chaw ntawm ib lub vaj huam sib luag, thiab vim tias cov xov hluav taws xob tuaj yeem sib cuam tshuam (uas tuaj yeem ua kom mob nyob ib puag ncig lwm sab), nws yog qhov zoo dua rau hauv kev ncig ntau dua li ntawm ib txheej.

Technically ob chav vaj huam sib luag yog ib hom ntawm PCB Circuit Board yog qhov tseem ceeb nyob rau hauv, nws yog lub hom phiaj ntawm qhov zoo, kom pom tias lub rooj tsavxwm PCB pawg thawj coj vaj huam sib luag yog yooj yim, kev nkag siab ntawm ib pawg vaj huam sib luag yog ntseeg tau tias cov phooj ywg tuaj yeem tuav, yog qhov txuas ntxiv ntawm tib lub vaj huam sib luag, ob chav vaj huam sib luag txhais tau tias tib lub vaj huam sib luag txoj kab txaus kom mus rau qhov tsis sib xws, ob chav vaj huam sib luag, thiab muaj qhov tseem ceeb yog qhov kev coj qhia.Qhov taw tes yooj yim yog tias ob tog kab, ob tog ntawm kab! bracket yog: ob tog sided line board yog ob chav vaj huam sib luag! Qee tus phooj ywg yuav nug xws li lub rooj tsavxwm ob tog hlau, tab sis tsuas yog ib sab muaj cov khoom siv hluav taws xob, xws li lub rooj tsav xwm tom qab txhua daim yog ob lub vaj huam sib luag lossis tib lub vaj huam sib luag? Cov lus teb yog pom tseeb , xws li lub rooj tsavxwm yog ob chav vaj huam sib luag, tsuas yog hauv chav tsev txua vaj huam sib luag mounted ntawm qhov chaw.

Multilayer Circuit Court board yog qhov yooj yim kom paub qhov txawv

Circuit board raws li kev txiav txim siab ntau npaum li cas ntawm cov txheej txheem thaiv cov teeb meem nyuaj thiab machining tus nqi, cov hluav taws xob Circuit Court board nrog ib kab thiab ob kab, feem ntau paub tias yog tib lub vaj huam sib luag thiab ob chav vaj huam sib luag, cov khoom siv hluav taws xob siab kawg, txawm li cas los xij, vim tias cov khoom tsim chaw yam , ntxiv rau cov xov hluavtaws saum npoo, sab hauv pawg ntawm cov xov tooj cua multilayer, cov txheej txheem ntau lawm, ua rau txhua txheej tom qab kab, dua los ntawm cov cuab yeej kho qhov muag muab tso rau, nias, cia cov lus tswj ntawm ntau txheej Circuit Court hauv ib daim ntawm Circuit board.Commonly paub raws li multilayer Circuit board board.nyob Circuit Court board ntau dua lossis sib npaug rau 2 txheej tuaj yeem raug hu ua multi-layer Circuit board.Multi-txheej Circuit Court board tuaj yeem faib ua ntau txheej txheej Circuit Court board, ntau txheej mos thiab tawv Circuit Court board, multi -ib txheej mos thiab tawv ua ke pawg thawj coj saib hauv pawg thawj coj saib.

Lub hnub yug ntawm multilayer pawg thawj coj hauv pawg thawj coj saib

Qhov nce ntawm IC pob khoom ua rau lub siab ntawm kev sib tshuam, uas yuav tsum tau siv ntawm ntau qhov chaw ua haujlwm.Unforeseen tsim teeb meem xws li suab nrov, yuam kev muaj peev xwm, hla lub ntsej muag tshwm nyob rau hauv cov ntawv luam tawm ntawm lub voj voos. lub teeb liab kab ntev thiab zam kev cov kab ke uas tsis sib haum.Ob tiaj, hauv tib lub vaj huam sib luag, lossis txawm tias nyob rau hauv lub vaj huam sib luag ob tog, cov kev cai no tsis tuaj yeem txaus siab teb vim muaj cov neeg hla kev tsawg uas tuaj yeem ua tau.Hauv ntau ntawm kev sib tshuam thiab hla kev xav tau, pawg thawj coj saib pawg yuav tsum tau nthuav dav mus rau ntau tshaj ob txheej kom ua tiav qhov ua tau zoo.Yog li ntawd, lub hom phiaj tseem ceeb ntawm ntau txheej Circuit Court board yog kom muaj kev ywj pheej ntau rau cov khoom siv hluav taws xob tsis yooj yim thiab / lossis lub suab nrov kom raug xaiv los tsim nyog. cov kab hlau rhuav.A multilayer Circuit Board pawg thawj coj muaj tsawg kawg peb txheej txheej, ob tus ntawm muaj txheej saum npoo, thiab txheej txheej ntxiv yog synthesized nyob rau hauv lub rwb thaiv tsev board.Qhov hluav taws xob kev sib txuas ntawm lawv feem ntau yog ua los ntawm plating los ntawm qhov nyob rau hauv ntu ntu ntawm Circuit Court board.Multilayer luam tawm Circuit Board, zoo li ob daim txiag, feem ntau plated los ntawm - orifice daim hlau tshwj tsis yog muaj lwm yam cim.

Multilaminates yog tsim los ntawm stacking ob lossis ntau cov khaubncaws sab nraud povtseg ntawm Circuit Court nyob rau sab saum toj ntawm txhua lwm yam, nrog kev ntseeg tau ua ntej kev teeb tsa sib txuas ntawm lawv.Vim cov drilling thiab electroplating tau ua ua ntej tag nrho cov khaubncaws sab nraud povtseg tau ua ke, cov txheej txheem no ua txhaum txoj kev lag luam ib txwm los ntawm kev pib .Qhov ob txheej sab hauv yog tsim los ntawm cov tsoos ob txheej, thaum cov khaubncaws sab nraud yog tsim los ntawm cov vaj huam sib luag sib cais.Yog hais tias tau dov, cov phaj sab hauv yuav raug laum, electroplated los ntawm lub qhov, hloov ntawm kab, tsim thiab etched.Qhov sab nraud txheej ntawm lub qhov yog lub teeb liab txheej, uas yog plated los ntawm txoj hauv kev xws li tsim cov nplhaib sib npaug ntawm lub kaum sab hauv ntawm lub qhov.Qhov txheej tau tom qab sib dhos ua ke los ua ntau lub zog ntawm cov substrates, uas tuaj yeem sib cuam tshuam los ntawm yoj soldering.

Qhov ua kom tiav tau nyob rau hauv cov xovxwm hydraulic lossis hauv kev tswj hwm overpressure (autoclave) .Nyob rau hauv cov xovxwm, cov khoom siv tau npaj (rau siab stacks) muab tso rau hauv qhov txias lossis preheated siab (cov khoom siv rau lub siab hloov dua siab tshiab kub tau muab tso rau ntawm 170-180 ° C) .Qhov lub khob hloov kub yog qhov kub ntawm thaj chaw amorphous ntawm ib lub polymer (cob) lossis ib feem ntawm crystalline polymer hloov los ntawm ib qho nyuaj, theej nkig lub xeev mus rau khov, cov roj hmab hauv lub xeev.

Multilaminates tau muab tso rau hauv kev siv cov khoom siv hluav taws xob tshwj xeeb (khoos phis tawj, khoom siv tub rog), tshwj xeeb tshaj yog thaum muaj qhov hnyav thiab ntim ntau dhau.Yuav li cas, qhov no tuaj yeem ua tiav los ntawm kev nce tus nqi laminates hauv kev pauv rau ntau qhov chaw thiab tsawg dua.Hauv lub voj voog nrawm, laminates kuj tseem muaj txiaj ntsig zoo li lawv muab cov qauv siv luam tawm Circuit Board nrog ntau tshaj ob txheej ntawm cov laug cam rau cov xov hlau thiab muab thaj chaw loj hauv av thiab muaj zog.

Qhov saum toj no yog qhia kom paub qhov sib cais ntawm ob daim phiaj Circuit Court ntau thiab ntau txheej Circuit Court board, Kuv vam tias koj yuav nyiam; Peb yog cov chaw tsim hluav taws xob Circuit Court manufacturers , txais tos nug txog
