Koj puas muaj kev tsis ntseeg, vim li cas aluminium substrate zoo dua FR-4?
Aluminium pcb muaj kev ua haujlwm zoo, tuaj yeem txias thiab kub dabtsi yog khoov, txiav, drilling thiab lwm yam kev ua haujlwm, tsim ntau yam duab thiab ntau thiab tsawg ntawm lub rooj tsavxwm. Lub FR4 Circuit Court board yog qhov yooj yim rau kev tawg, stripping thiab lwm yam teeb meem, thiab nws nyuaj rau kev ua haujlwm. Yog li ntawd, txhuas substrate feem ntau yog siv nyob rau hauv high-kev ua tau zoo hluav taws xob cov khoom, xws li LED teeb pom kev zoo, automotive electronics, fais fab mov thiab lwm yam kev lag luam.
Tau kawg, aluminium pcb kuj muaj qee qhov tsis zoo. Vim nws cov hlau substrate, tus nqi ntawm aluminium substrate yog siab dua, thiab nws feem ntau kim dua FR4. Tsis tas li ntawd, vim tias aluminium substrate tsis yooj yim rau kev sib txuas nrog cov pins ntawm cov khoom siv hluav taws xob dav dav, kev kho tshwj xeeb, xws li metallization, yuav tsum tau ua, uas ua rau cov nqi tsim khoom. Tsis tas li ntawd, lub rwb thaiv tsev txheej ntawm aluminium substrate kuj yuav tsum tau kho tshwj xeeb los xyuas kom meej lub tshav kub dissipation kev ua tau zoo yam tsis muaj kev cuam tshuam cov teeb liab kis tau tus mob.
Ntxiv rau qhov sib txawv ntawm tus nqi, kuj tseem muaj qee qhov sib txawv ntawm txhuas pcb thiab FR4 hais txog kev ua haujlwm thiab kev siv ntau yam.
Ua ntej ntawm tag nrho cov, aluminium substrate muaj kev ua tau zoo ntawm cov cua sov dissipation, uas tuaj yeem cuam tshuam cov cua sov uas tsim los ntawm lub rooj tsav xwm Circuit Court sai. Qhov no ua rau aluminium substrate haum rau high-power, high-density Circuit Court tsim, xws li LED teeb, fais fab modules, thiab lwm yam. Nyob rau hauv sib piv, lub tshav kub dissipation kev ua tau zoo ntawm FR4 yog kuj tsis muaj zog, thiab nws yog tsim nyog rau tsawg zog. tsim Circuit Court.
Qhov thib ob, lub peev xwm nqa tam sim no ntawm aluminium substrate yog ntau dua, uas tsim nyog rau kev siv hluav taws xob ntau thiab siab tam sim no. Nyob rau hauv lub high-power Circuit Court tsim, tam sim no yuav ua kom sov, thiab lub siab thermal conductivity thiab zoo tshav kub dissipation kev ua tau zoo ntawm txhuas substrate yuav zoo dissipate lub tshav kub, yog li ua kom ntseeg tau thiab stability ntawm lub Circuit Court. Lub peev xwm nqa tam sim no ntawm FR4 yog qhov me me thiab tsis haum rau kev tsim hluav taws xob siab, kev tsim hluav taws xob ntau zaus.
Tsis tas li ntawd, aluminium substrate seismic kev ua tau zoo kuj zoo dua li FR4, tuaj yeem tiv thaiv kev poob siab thiab kev co, yog li hauv tsheb, railway thiab lwm yam kev tsim hluav taws xob tsim hluav taws xob, aluminium substrate kuj tau siv dav. Nyob rau tib lub sijhawm, aluminium substrate kuj muaj kev ua haujlwm zoo los tiv thaiv electromagnetic cuam tshuam, uas tuaj yeem tiv thaiv hluav taws xob tsis zoo thiab txo kev cuam tshuam hauv Circuit Court.
Feem ntau, txhuas pcb muaj qhov ua tau zoo ntawm cov cua sov dissipation, lub peev xwm nqa tam sim no, seismic kev ua tau zoo thiab electromagnetic cuam tshuam tsis zoo dua li FR4, thiab yog tsim rau high-power, high-density thiab high-frequency circuit design. FR4 yog tsim rau kev tsim hluav taws xob hauv hluav taws xob, xws li xov tooj ntawm tes, laptops thiab lwm yam khoom siv hluav taws xob. Tus nqi ntawm aluminium substrate feem ntau yog siab dua, tab sis rau kev tsim hluav taws xob siab, kev xaiv ntawm aluminium substrate yog ib kauj ruam tseem ceeb heev.
Hauv cov ntsiab lus, aluminium pcb thiab FR4 yog tsim rau ntau hom kev siv hluav taws xob thiab muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Thaum xaiv cov khoom siv hluav taws xob hauv Circuit Court, nws yuav tsum ntsuas ntau yam raws li qhov tshwj xeeb daim ntawv thov scenarios thiab yuav tsum tau xaiv cov ntaub ntawv tsim nyog tshaj plaws.
