Nrog rau kev hloov pauv sai ntawm lub neej niaj hnub tam sim no uas yuav tsum tau muaj ntau yam txheej txheem ntxiv uas yuav ua kom zoo dua qhov kev ua tau zoo ntawm koj lub rooj sib tham hauv kev sib raug zoo nrog lawv cov kev npaj siv, lossis pab nrog ntau theem kev sib dhos kom txo tau kev ua haujlwm thiab txhim kho kev ua tau zoo, ANKE PCB tau mob siab rau. txhawm rau txhim kho thev naus laus zis tshiab kom tau raws li cov neeg siv khoom xav tau.
Ntug connector bevelling rau kub ntiv tes
Edge connector bevelling feem ntau yog siv hauv cov ntiv tes kub rau kub plated boards los yog ENIG boards, nws yog txiav los yog shaping ntawm ntug connector ntawm ib lub kaum ntse ntse.Ib qho beveled connectors PCI lossis lwm yam ua rau nws yooj yim dua rau lub rooj tsavxwm kom nkag mus rau hauv lub connector.Edge Connector bevelling yog ib qho parameter nyob rau hauv cov lus txiav txim uas koj yuav tsum tau xaiv thiab xyuas qhov kev xaiv no thaum xav tau.
Carbon luam ntawv
Cov pa luam yeeb luam tawm yog ua los ntawm cov kua roj carbon monoxide thiab tuaj yeem siv rau kev sib cuag keyboard, LCD hu thiab jumpers.Kev luam ntawv yog ua nrog cov pa roj carbon ink.
Cov ntsiab lus carbon yuav tsum tiv thaiv cov hlau los yog HAL.
Rwb thaiv tsev lossis Carbon dav yuav tsis txo qis dua 75% ntawm tus nqi nominal.
Qee lub sij hawm lub ntsej muag peelable yog tsim nyog los tiv thaiv cov fluxes siv.
Peelable soldermask
Peelable soldermask Lub peelable tiv thaiv txheej yog siv los npog thaj chaw uas tsis yog yuav tsum tau soldered thaum lub sij hawm solder yoj txheej txheem.Cov txheej txheem yooj yim no tuaj yeem raug tshem tawm tom qab tau yooj yim kom tawm hauv cov ntaub qhwv, qhov thiab cov khoom siv tau zoo meej rau cov txheej txheem sib dhos thiab cov khoom sib txuas / cov khoom sib txuas.
Blind & faus vais
Qhov muag tsis pom Via yog dab tsi?
Nyob rau hauv qhov muag tsis pom ntawm, qhov ntawm kev txuas cov txheej sab nraud rau ib lossis ntau txheej txheej hauv PCB thiab yog lub luag haujlwm rau kev sib txuas ntawm cov txheej sab saum toj thiab cov txheej sab hauv.
Buried Via yog dab tsi?
Nyob rau hauv ib tug faus ntawm, tsuas yog lub puab txheej ntawm lub rooj tsavxwm yog kev cob cog rua ntawm lub via.Nws yog "faus" hauv lub rooj tsavxwm thiab tsis pom los ntawm sab nraud.
Qhov muag tsis pom thiab faus vias yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv HDI cov laug cam vim tias lawv ua kom zoo dua lub rooj tsavxwm yam tsis muaj qhov loj ntawm lub rooj tsavxwm lossis tus naj npawb ntawm pawg thawj coj saib.
How to make blind & faus vias
Feem ntau peb tsis siv qhov tob tswj laser drilling los tsim qhov muag tsis pom thiab faus vias.Ua ntej peb xyaum ib los yog ntau tshaj cores thiab phaj los ntawm lub qhov.Tom qab ntawd peb tsim thiab nias lub pob.Cov txheej txheem no tuaj yeem rov ua dua ob peb zaug.
Qhov no txhais tau tias:
1. A Via ib txwm yuav tsum tau txiav los ntawm ib tus lej ntawm cov txheej tooj liab.
2. Ib Via tsis tuaj yeem xaus rau sab saum toj ntawm ib qho tseem ceeb
3. A Via tsis tuaj yeem pib ntawm sab hauv qab ntawm ib qho tseem ceeb
4. Qhov muag tsis pom los yog faus Vias tsis tuaj yeem pib lossis xaus rau hauv lossis kawg ntawm lwm qhov muag tsis pom kev / faus ntawm qhov tshwj tsis yog tias ib qho yog nyob rau hauv tag nrho (qhov no yuav ntxiv tus nqi ntxiv raws li lub voj voog xovxwm ntxiv).
Tswj impedance
Kev tswj hwm impedance tau yog ib qho kev txhawj xeeb tseem ceeb thiab teeb meem loj hauv kev tsim pcb high-speed.
Hauv kev siv ntau zaus, kev tswj hwm impedance pab peb kom ntseeg tau tias cov teeb liab tsis raug degraded thaum lawv taug kev ncig PCB.
Kev tsis kam thiab reactance ntawm ib qho hluav taws xob hluav taws xob muaj qhov cuam tshuam loj rau kev ua haujlwm, vim cov txheej txheem tshwj xeeb yuav tsum tau ua kom tiav ua ntej lwm tus los xyuas kom muaj kev ua haujlwm zoo.
Qhov tseem ceeb, tswj impedance yog qhov sib piv ntawm cov khoom siv substrate nrog cov kab ntev thiab qhov chaw kom ntseeg tau tias qhov impedance ntawm kab teeb liab yog nyob rau hauv ib feem ntawm cov nqi tshwj xeeb.
