PCB yezvinyorwa kuiswa

1.Glass Cloth Substrate: Fr-4, Fr-5

Nechero yakasarudzika yemagetsi yakasarudzika ne epoxy phenolik epoxic esin mushure mekudzvinyirira kwakanyanya, kudzvinyirira, kudzvinyirira uye kuve ndiro-shoma-senge zvigadzirwa zvekumanikidza.

Epoxy Girazi Fiber Cloth Substrate (inowanzozivikanwa se: EPOXY Bhodhi, Fiberglass Board, Fiberboard, FR4). Epoxy Girazi Fiber Haisi iyo kirasi yeiyo substrate ine epoxy resin seBinder uye yemagetsi giredhi fiber filer

Epoxy Girazi Fiber Cloth Cladding Bhodhi ine simba rakanyanya Iyo inonyanya kushandiswa kushandiswa muhunhu hwese hwemhangura copper cladding bhodhi, huwandu hukuru hwekirasi.

2.paper Substrate: Fr-1, Fr-2, Fr-3, Et-3

Phenolic propen substrate ndeye phenolol resin sokubuda, ine huni propiti fiber jira seyepamhepo yekusimbisa zvinyorwa.f4, G10

3.com substrate: cem-1 uye cem-3

Rudzi urwu rwekutsiva runonyanya kuve rwe cem series mhangura-clated ndiro, ndeipi cem-1 (epoxy pepa-based core zvinhu) uye cem-3 (epoxy girazi nonwoven core zvinhu) marudzi maviri akakosha e cem. CEM Shicle Plate ine kugona kugona inenge 80% ye fr-4, mutengo wakaderera pane fr-4 bhodhi.

Zvimiro

Fr-4 Epoxy Girazi Fiber Cloth Substrate, kirasi yeiyo substrate ine epoxy resin seBinder uye yemagetsi giredhi glas fiber jira sekusimbisa. Shebha rayo rekubhomba uye remukati rakapetwa rakatetepa mhangura-copper-clad leminate dzakakosha substrates yekugadzira akawanda akadhindwa matunhu ematunhu.

Kuita

Epoxy Girazi Fiber Cloth Substrate Propertial Properties, Dimensional Kugadzikana, kukanganisa kurwisa, kuramba kwakanyorova kwakakwirira kupfuura iyo pepa substrate. Iyo ine zvinhu zvakanakisa zvemagetsi zvemagetsi, tembiricha yekushanda, uye kuita kwayo hakukanganiswe nemamiriro ekunze. Mukugadzirisa tekinoroji, pane mamwe magetsi egirazi egirazi jira substrate ane hukuru hwakakura. Izvi zvigadzirwa zvinonyanya kushandiswa kune kaviri-yakagadziriswa PCB, ine huwandu hwakawanda.

Zvishandiso

Epoxy Fiberglass Cloth Substrate, iyo inonyanya kushandiswa chigadzirwa mhando Fr-4, nekuda kwemagetsi zvigadzirwa zvekuisa tekinoroji uye PCB tekinoroji yekuvandudza zvido, uye kubuda kweiyo yepamusoro tg fr-4 zvigadzirwa.
