Qhov sib txawv thiab daim ntawv thov ntawm aluminium substrate thiab iav fiber board
PCB, uas yog, lub rooj tsav xwm luam tawm, yog lub ntsiab lus dav dav ntawm cov khoom siv hluav taws xob feem ntau, uas tuaj yeem muab faib ua cov duab los qhia, semi-fiberglass board, fiberglass board, hlau substrate, thiab lwm yam.
1, fiberglass board (FR4, ib sab, ob sab, ntau txheej PCB Circuit Board, impedance board, dig muag qhov rooj), haum rau lub computer, xov tooj ntawm tes thiab lwm yam khoom siv hluav taws xob thiab digital.
Muaj ntau lub npe rau fiberglass board. Cia peb saib ua ntej; FR-4 tseem hu ua fiberglass board; Fiberglass board; FR4 stiffening phaj; FR-4 epoxy resin phaj; Nplaim retardant rwb thaiv tsev board; Epoxy phaj, FR4 lub teeb swb phaj; Epoxy iav daim ntaub phaj; Circuit board drilling pem teb feem ntau yog siv rau kev ntim khoom yooj yim, thiab tom qab ntawd qhwv nrog ntaub, tawv, thiab lwm yam, ua kom zoo nkauj phab ntsa, qab nthab kho kom zoo nkauj. Nws yog dav siv. Nws muaj cov yam ntxwv ntawm lub suab nqus, suab rwb thaiv tsev, rwb thaiv tsev kub, kev tiv thaiv ib puag ncig thiab nplaim hluav taws.
Fiberglass board yog cov khoom sib xyaw ua los ntawm epoxy resin, muab tub lim thiab iav fiber ntau.
Cov yam ntxwv tseem ceeb thiab kev siv ntawm FR4 lub teeb phaj: ruaj khov hluav taws xob rwb thaiv tsev, zoo flatness, du nto, tsis muaj pits, ntau thickness kam rau ua, haum rau kev ua tau zoo hluav taws xob rwb thaiv tsev cov khoom, xws li FPC reinforcement board, tin furnace kub resistant board, carbon zaj duab xis, precision hnub qub log, PCB xeem khib, hluav taws xob (hluav taws xob) cov cuab yeej rwb thaiv tsev muab faib, rwb thaiv tsev phaj, transformer rwb thaiv tsev qhov chaw, lub cev muaj zog rwb thaiv tsev qhov chaw, deflection coil terminal board, hluav taws xob hloov rwb thaiv tsev board.
Vim nws cov khoom zoo, fiberglass board yog dav siv hauv cov khoom siv hluav taws xob, hluav taws xob thiab cov khoom siv digital. Tus nqi siab dua daim ntawv thiab ib nrab iav fiber ntau, tus nqi tshwj xeeb txawv raws li cov khoom xav tau. Fiberglass board kuj tau siv dav hauv cov khoom siv hluav taws xob digital.
Vim nws qhov tshwj xeeb zoo, fiberglass board tau siv dav hauv kev lag luam hluav taws xob. Fiberglass board tuaj yeem sib sau ua ke hauv ntau txoj hauv kev, xws li V-slot, punch qhov, choj, thiab lwm yam.
2, txhuas substrate (ib leeg-sab txhuas substrate, ob-sided txhuas substrate), txhuas substrate mas muaj zoo heev tshav kub dissipation kev ua tau zoo, haum rau LED technology. Lub hauv paus yog ua los ntawm aluminium.
Aluminium substrate yog ib hom hlau - clad tooj liab laminate nrog zoo tshav kub dissipation. Feem ntau hais lus, lub vaj huam sib luag muaj peb txheej, uas yog txheej txheej hauv Circuit Court (copper foil), txheej rwb thaiv tsev thiab hlau puag. Rau kev siv high-end, muaj txheej txheej txheej, rwb thaiv tsev txheej, aluminium puag, rwb thaiv tsev txheej, Circuit Court txheej ob lub vaj huam sib luag tsim. Kev siv tsawg heev yog multilaminates, uas tuaj yeem ua los ntawm cov khoom siv sib xyaw zoo tib yam, cov txheej txheej insulating, thiab txhuas hauv paus.
Aluminium substrate yog ib hom PCB. Aluminium substrate yog cov hlau-raws li cov ntawv luam tawm nrog siab thermal conductivity. Feem ntau siv rau lub hnub ci zog, LED teeb thiab lwm yam khoom uas xav tau cua sov dissipation, tab sis cov khoom siv hauv Circuit Court yog aluminium alloy. Yav dhau los, peb cov khoom siv hauv Circuit Court board yog iav fiber ntau. Txawm li cas los xij, vim qhov kub ntawm LED, lub rooj tsav xwm ntawm LED teeb feem ntau yog txhuas substrate, uas tuaj yeem ua cua sov sai. Lwm yam khoom siv lossis hluav taws xob Circuit Court boards rau fiberglass board!
