High zaus board coj mus kuaj manufacturersmuaj peev xwm muab tag nrho cov saw kaw-voj tsim kev txhawb nqa los ntawm impedance simulation rau pawg optimization, npog cov kev ua tau zoo lav qhov yuav tsum tau muaj cov teeb liab ntau zaus kis tau tus mob thoob plaws lub voj voog.
Impedance simulation thiab meej tswj
Tag nrho scene impedance xam: npog lub ntsiab impedance lub hom phiaj xws li ib qho kawg 50 Ω thiab qhov sib txawv 100 Ω, yoog mus rau cov kab sib txuas sib txawv xws li microstrip kab thiab stripline, xauv qhov impedance sib txawv ua ntej hauv ± 5%, thiab ua tiav ± 2% ultra-siab qhov tseeb.
Multi-dimensional simulation pov thawj: tso siab rau cov cuab yeej tshaj lij xws li HFSS thiab Polar SI9000, ua tiav qhov kev poob qis, rov qab poob simulation thiab impedance continuity tsom xam, nrhiav cov teeb liab tsis muaj zog xws li ntawm qhov thiab txheej hloov, thiab zam teeb liab teeb meem cuam tshuam los ntawm impedance mismatch tom qab ntau lawm.
Kev ntsuas thiab ntsuas qhov ntsuas: Tsim cov ntaub ntawv simulation rau kev ntsuas nrog cov txheej txheem ntau lawm, ua ke nrog TDR lub sij hawm-domain reflectometer retesting mechanism, los xyuas kom meej tias cov kev simulation tau tswj nyob rau hauv ib qho me me ntawm impedance sib txawv ntawm cov khoom tiav lawm.

Customized optimization ntawm stacked architecture -
Kev tsim kho qhov loj me: ua kom tiav txheej txheej raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab cov teeb liab tus nqi, xaiv cov core boards, semi-kho nplooj ntawv, thiab tooj liab thickness configurations, nruj me ntsis raws li lub hauv paus ntsiab lus ntawm qhov chaw symmetry, thiab zam compression warping teeb meem.
Kev ua kom zoo tshaj plaws ntawm cov txheej txheem sib xyaw ua ke: Kev siv lub tswv yim "txoj kev tseem ceeb", tsuas yog high-end high-frequency plates xws li PTFE thiab Rogers yog siv nyob rau hauv cov tub ntxhais high-frequency unit, thiab FR-4 yog siv nyob rau hauv lwm qhov chaw rau compress tus nqi ntau tshaj 70% thaum ua kom ntseeg tau kev ua tau zoo.
Cov txheej txheem kev txheeb xyuas kev sib raug zoo: nruj me ntsis tswj CTE qhov sib txawv ntawm cov khoom sib txawv hauv 20 ppm / degree, xyuas kom meej tias cov interlayer tev lub zog ntawm daim ntawv sib txuas tshwj xeeb rau PTFE thiab FR-4 sib xyaw compression ntau dua lossis sib npaug rau 0.8 N / mm, thiab tshem tawm qhov kev pheej hmoo ntawm delamination nyob rau hauv qhov kub thiab txias.
Txhawb nqa tus txheej txheem tag nrho
DFM manufacturability tshuaj xyuas: Tshuaj xyuas kab dav, kab sib nrug, lub nplhaib lub ntsej muag, lub ntsej muag lub ntsej muag, thiab sib txuas ib qho los ntawm ib qho los nthuav tawm cov kev pheej hmoo ntau lawm ua ntej thiab zam teeb meem qhov kev tsim ua tau raws li qhov yuav tsum tau ua tab sis tsis tuaj yeem ua tiav.
Kev xaiv cov khoom siv tshwj xeeb thiab kev hloov kho: Rau cov xwm txheej sib txawv xws li 6G millimeter yoj, 77GHz tsheb radar, AI suav pawg, thiab lwm yam, raug phim Rogers, Taikangli thiab lwm yam substrates, sib npaug Dk / Df kev ua tau zoo thiab kev ua tau zoo.
Tag nrho cov txheej txheem engineering txhawb rau kev sim ntau lawm: los ntawm EQ kev pom zoo, thawj tsab ntawv pov thawj mus rau qhov txawv txav kaw-voj, pab pawg kws tshaj lij ua raws li ntawm qhov chaw thaum lub sijhawm sim ua haujlwm, muab cov lus qhia daws teeb meem nyob rau tib hnub, thiab ua kom muaj kev tsaws sai thiab loj ntawm cov laug cam ntau zaus.
