Taw qhia
Hauv kev lag luam hluav taws xob sib tw niaj hnub no, kev tswj hwm tus nqi tau nthuav dav txhua yam ntawm cov txheej txheem tsim khoom. Thaum xa cov ntaub ntawv PCB tsim rau cov chaw tsim khoom rau PCBA kev tsim khoom, ntau tus neeg siv khoom feem ntau tsuas yog tsom rau kev txo cov nqi ntawm cov khoom siv thaum saib xyuas cov nqi zais uas ua los ntawm PCB cov txheej txheem stackup. Kev nrhiav ntau dhau ntawm txoj kev tswj hwm impedance thiab ntxiv cov txheej txheem tsis tsim nyog tuaj yeem tsav ncaj qha rau cov nqi tsim khoom. Los ntawm optimizing lub stackup qauv thaum ntxov nyob rau hauv cov txheej txheem engineering, nws muaj peev xwm tsis tsuas yog txo cov khoom siv thiab tsim lub sij hawm, tab sis kuj los txhim kho ntau lawm yield.
Nqi Traps hauv Stack-Up Design
Ntau tus qauv PCB thaum ntxov ib txwm siv cov txheej txheem ntau dua li qhov xav tau los ua kom yooj yim txoj kev. Piv txwv li, ib qho kev teeb tsa uas tuaj yeem ua tiav ntawm plaub-txheej board yog qhov tsis tsim nyog hloov kho rau lub rooj tsav xwm rau 6-txheej, lossis cov khoom siv high-frequency, high-speed yog blindly stacked nyob rau hauv cov xwm txheej uas tsis muaj high-frequency teeb liab yuav tsum tau. Xws li cov qauv tsim tsis tsuas yog nce tus nqi ntawm cov khoom siv rau ib lub rooj tsavxwm thaum ntxov tab sis kuj ua rau cov khoom seem ntau dua vim qhov nyuaj ntawm cov txheej txheem tsim khoom, uas ncaj qha tsav mus rau tag nrho cov nqi yuav khoom ntawm tag nrho cov khoom ntawm PCBA. Txheej stackup tsim tsis yog hais txog lub cev ntawm cov khaubncaws sab nraud povtseg; nws kuj muaj kev xaiv ntawm core board thickness, prepreg hom, thiab tooj liab ntawv ci specifications. Ib tug ntawm peb cov neeg tau ntsib ib qhov project uas tus thawj tsim tau teev ib yam tshwj xeeb ntawm board nrog ib tug tshwj xeeb thickness. Txij li lub rooj tsavxwm no tsis yog cov khoom tshwj xeeb hauv kev ua lag luam, nws yuav tsum tau ua haujlwm siab ua haujlwm. Qhov no tsis tsuas yog txuas ntxiv lub voj voog xa khoom tab sis kuj ua rau tus nqi them ntau dua 10% ntawm cov khoom siv substrate nqi ib PCB.
Ib txoj hauv kev tsim engineering los txo tus nqi thiab kev txhim kho kev ua tau zoo
Cov ntsiab lus tseem ceeb tom qab ua tiav kev txuag nqi yog nyob rau hauv kev tsim rau kev tsim khoom (DFM). Thaum tau txais cov ntaub ntawv tsim, pab pawg engineering ntawm cov chaw tsim khoom siv hluav taws xob yuav tsum rov ntsuas cov qauv laminate. Yog hais tias lub teeb liab kev ncaj ncees metrics teev los ntawm tus neeg siv daim ntawv tso cai, engineers yuav txo tau ib tug rau-txheej board mus rau ib tug plaub-txheej board los ntawm kev kho ntawm qhov chaw thiab kab sib nrug. Xwb, thaum ua kom ntseeg tau kev ua tau zoo, lawv tuaj yeem hloov tsis tseem ceeb, tus nqi siab laminates nrog cov khoom siv hluav taws xob qis dua uas muab cov kev ua tau zoo sib xws, yog li ncaj qha txiav cov nqi kwv yees li 5% mus rau 8% ntawm theem substrate. Tsis tas li ntawd, kev siv vaj huam sib luag muaj feem cuam tshuam rau cov nqi. Cov kws tsim qauv tsim kho lub hom phiaj ntawm kev tsim khoom nrog kev cob qhia cov vaj huam sib luag layout modules, kho cov PCB qhov ntev thiab cov haujlwm ntawm cov ntawv sau npe kom nce tus naj npawb ntawm panels rau ib daim ntawv los ntawm 15%. Qhov no nthuav tawm cov nqi ntawm drilling, plating, thiab kev kho saum npoo ntawm ib tus neeg vaj huam sib luag. Qhov kev tsim qauv tsim qauv tsim qauv tshiab no tuaj yeem txo qis tag nrho cov nqi tsim khoom los ntawm kwv yees li 15% yam tsis muaj kev cuam tshuam rau qhov kawg ntawm kev ntsuas hluav taws xob.
Sib npaug Impedance Requirements thiab cov txheej txheem khoom siv
Rau cov haujlwm nyuaj, impedance tswj ncaj qha txiav txim siab kev ua haujlwm hauv Circuit Court. Ntau qhov kev tsim qauv, nyob rau hauv kev nrhiav kev pom cov teeb liab txoj hauv kev, feem ntau xav tau kev tsim khoom siab heev. Los ntawm kev tsim cov kev xav, qhov no txhais tau rau kev tswj xyuas nruj dua thiab muaj kev pheej hmoo siab dua ntawm cov khoom seem. Los ntawm kev rov tshuaj xyuas cov txheej txheem tsim thiab kho cov dielectric thickness thiab tooj liab thickness faib ntawm cov teeb liab txheej raws li cov kev xav tau tshwj xeeb, cov engineers tuaj yeem so tsis tsim nyog xav tau ntawm kev tsim precision thaum ua kom ntseeg tau tias impedance qhov tseem ceeb raws li cov qauv tsim. Qhov kev nplua-tuning ntawm cov txheej txheem margins ua rau cov chaw tsim khoom ua kom tiav kev tsim khoom thaum tuav lub xeev ruaj khov, muaj txiaj ntsig zoo. Los ntawm kev txo qis kev rov ua haujlwm thiab cov khoom seem los ntawm kev sim impedance ua tsis tiav, cov neeg siv khoom tsis tsuas yog txuag cov nqi tsim khoom ncaj qha tab sis kuj tseem ua rau lub sijhawm luv luv rau kev ua lag luam, txo qis peev hauv cov khoom muag.
Tsim kom muaj qhov kawg-rau-End Collaborative Engineering Optimization Mechanism
Tus nqi ntawm engineering optimization nyob rau hauv kev pub kev tsim khoom rov qab rau hauv R & D txheej txheem. Cov tuam txhab tsim hluav taws xob yuav tsum tau koom nrog hauv cov haujlwm thaum ntxov raws li qib prototyping los tshuaj xyuas cov ntsiab lus tsis txaus ntseeg hauv PCB pawg tsim. Los ntawm kev siv software simulation los txheeb xyuas cov qauv tsim, lawv tuaj yeem txiav txim siab seb cov txheej twg yog qhov tseem ceeb thiab qhov twg tuaj yeem sib sau ua ke lossis ua kom zoo dua. Txoj hauv kev no-tsim tus nqi ciam teb thaum lub sijhawm tsim qauv- zam cov nqi pwm ntxiv thiab cov nqi tsim hluav taws xob tsim hluav taws xob uas tshwm sim los ntawm kev hloov kho tsim tom qab hauv cov txheej txheem. Pab pawg kws tshaj lij engineering yuav tsum muaj peev xwm los txhais cov kev qhia tshwj xeeb rau kev ntsuas tus nqi, nrog rau lub hom phiaj ntawm kev pab cov neeg siv khoom kom siv tau cov peev txheej los ntawm kev tshawb fawb txheej txheej thiab kev xaiv ntawm kev tsim khoom, tag nrho thaum nyob rau hauv cov txheej txheem kev ua tau zoo.
