Qhov tseem ceeb sib txawv hauv kev ua haujlwm ntawm HDI boards thiab pcbs li niaj zaus. Cias muab,HDI boardsyog qhov zoo dua li cov pcbs zoo tib yam hauv siab -frequency signal transmission, anti-interference peev, thiab heat dissipation performance, tab sis tus nqi kuj siab dua. Muaj qhov txawv tshwj xeeb raws li hauv qab no:
1. Muaj peev xwm kis tau tus mob ntau zaus
HDI boards txo cov teeb liab txoj hauv kev los ntawm micro qhov thiab qhov muag tsis pom kev faus qhov thev naus laus zis, txhawb nqa siab - zaus teeb liab kis mus txog 40GHz, haum rausiab - zausCov xwm txheej xws li 5G hauv paus chaw nres tsheb thiab siab - cov khoom siv network ceev. Txawm li cas los xij, cov pcbs zoo ib yam muaj cov teeb liab txoj kev ntev, cov kab mob parasitic siab, thiab tsis muaj zog siab - zaus ua haujlwm, ua rau lawv tsim nyog rau tsawg- cov ntawv thov zaus xws li cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob.
2. Anti cuam tshuam muaj peev xwm
HDI boards siv tshwj xeeb substrates xws li PTFE thiab LCP kom optimize dielectric zog, thiab txo cov xov tooj cua zaus cuam tshuam (RFI) thiab electromagnetic cuam tshuam (EMI) los ntawm microporous thev naus laus zis los txhim kho cov teeb liab kev ncaj ncees. Ordinary printed circuit boards muaj qhov tsis muaj zog tiv thaiv - muaj peev xwm cuam tshuam thiab tsim nyog rau cov khoom lag luam uas tsis xav tau cov teeb liab zoo.
3. Thaum tshav kub kub dissipation kev ua tau zoo
HDI boards ua tiav txoj hauv kev ua kom muaj cua sov ntau dua thiab muaj peev xwm ua kom muaj cua sov ntau dua los ntawm kev siv high- ntom ntom thiab micro qhov tshuab, ua rau lawv tsim nyog rau siab - cov khoom siv hluav taws xob xws li siab - kawg servers thiab automotive electronics. Ordinary printed circuit boards muaj qhov nruab nrab kub dissipation kev ua tau zoo thiab tsim nyog rau cov khoom siv hluav taws xob uas siv hluav taws xob tsawg.
4. Kev ua haujlwm hluav taws xob
HDI pawg thawj coj saib muaj txoj hauv kev luv luv, cov khoom seem me me los ntawm qhov, qis cov kab mob parasitic inductance thiab capacitance, thiab kev ua haujlwm hluav taws xob zoo dua, ua rau nws tsim nyog rau siab - cov ntaub ntawv xa mus ceev thiab siab - zaus teeb liab kis tau tus mob. Cov ntawv luam tawm ib txwm muaj hluav taws xob tsis muaj zog thiab tsim nyog rau qhov tsawg -frequency scenarios.
5. Qhov loj thiab qhov hnyav
HDI pawg thawj coj saib muaj cov kab hluav taws xob siab, nrog cov kab dav thiab qhov sib nrug tsawg dua 50 microns. Lub thickness ntawm lub rooj tsavxwm tuaj yeem compressed rau hauv 0.8 millimeters, ua rau nws me me thiab sib dua hauv qhov hnyav. Cov kab dav thiab qhov sib txawv ntawm cov pcbs zoo tib yam feem ntau tshaj 0.1 millimeters, thiab lub rooj tsavxwm thickness nce ntau nrog cov txheej txheej, ua rau qhov loj thiab qhov hnyav.
6. Tsim tau yooj yim
HDI boards txhawb siab tus lej suav / cov khoom siv suab zoo (xws li BGA, CSP, QFN), nrog rau kev tsim qauv siab thiab muaj peev xwm los siv ntau lub voj voog hauv qhov chaw tsawg. Ordinary pcb muaj cov kab hluav taws xob tsawg thiab kev tsim qauv yooj yim.
7. Daim ntawv thov scenarios
HDI boards feem ntau yog siv rau hauv kev lag luam xws li xov tooj ntawm tes, 5G chaw nres tsheb, automotive electronics, aerospace, cov cuab yeej kho mob, thiab lwm yam uas xav tau qhov chaw nruj thiab kev ua haujlwm. Ordinary pcbs yog dav siv hauv cov khoom siv hauv tsev, khoom siv hluav taws xob, teeb pom kev zoo thiab lwm yam khoom siv.
8. Tus nqi
Kev tsim cov txheej txheem ntawm HDI board yog complex, yuav tsum tau laser drilling, ntau nias, thiab lwm yam., thiab tus nqi yog ntau tshaj 30% siab tshaj li ntawm cov pcb zoo tib yam. Cov txheej txheem pcb zoo tib yam yog qhov yooj yim, haum rau loj - nplai ntau lawm, thiab muaj tus nqi qis.
Hauv luv luv, yog tias koj xav tau siab - zaus, siab - ceev, siab - kev ua haujlwm tsim hluav taws xob, HDI board yog qhov kev xaiv zoo dua; Yog tias tus nqi rhiab thiab kev ua haujlwm tsis siab, pcbs zoo tib yam txaus.
