Kodi pali kusiyana kotani pakati FR4 epoxy fiberglass board ndi 3240 epoxy fiberglass board?

The zoweta epoxy fiberglass bolodi zambiri 3240, ndi FR4 epoxy fiberglass board nthawi zambiri imakhala yochokera kunja. Koma zonsezi ndi zosiyana kwambiri ndi zinthu zakuthupi kapena mankhwala. Ndiroleni ndikudziwitse aliyense mwachidule:

1, 3240 epoxy galasi CHIKWANGWANI bolodi, ambiri dzina lonse: 3240 epoxy phenolic fiberglass nsalu laminate. Amagwiritsa ntchito guluu wa epoxy resin ndi zinthu za phenolic ngati machiritso. Kutentha nthawi zambiri kumakhala madigiri 155. Kuchita bwino kwa makina. Ndiwoyeneranso kwambiri ma transfoma ndi mafuta a transfoma. Kuchulukana sikudutsa mulingo wadziko lonse: 1.9.

Komabe, opanga ambiri apakhomo tsopano akutenga nawo gawo pazodzaza, monga ufa wa talcum, kuti apulumutse ndalama popanga. Kachulukidwe wawo wakula kwambiri. Zimachepetsanso kwambiri ntchito zamagetsi. Ndioyenera kuma projekiti otchinjiriza wamba.

2. FR4 epoxy glass fiber board. Glue epoxy imagwiritsidwa ntchito. Koma si mankhwala ochiritsira okhala ndi zinthu za phenolic. Koyera anachiritsa pa kutentha. Amafananizidwa ndi pulasitiki yoyera. Kutentha kumakhala kwakukulu kuposa madigiri 180. The Machining ntchito ndi wamphamvu kwambiri. Mnzake wina adachita nthabwala kuti kudula ndi makina odulira kumadula zipsera.

kusonyeza ntchito yake processing. Ndipo sichidzang’ambika kapena kusokoneza pamene chikugwiritsidwa ntchito. Mphamvu zamagetsi ndizolimba kwambiri. Ndizoyenera matabwa amagetsi amagetsi ndi ma laminates amkuwa. Zida zoyambira zimathanso kukhala nsalu zabwino zonse. Electronic fiber nsalu. Nthawi zambiri amakhala osalimba a 1.85. Kugonjetsedwa ndi dzimbiri ndi mankhwala.

3240 epoxy fiberglass board ndi FR4 epoxy fiberglass board ndiawiri odziwika bwino a epoxy fiberglass board omwe ali pamsika pano. Aliyense amati FR4 ndi yabwino kuposa 3240. Kodi pali kusiyana kotani pakati pawo?

Kusiyanitsa 1: FR4 ili ndi magwiridwe antchito abwino amoto.

FR4 ndi chopangidwa bwino cha 3240 epoxy glass fiber board. Ntchito yobwezeretsanso lawi la FR4 epoxy glass fiber board ikukumana ndi muyezo wadziko lonse wa UL94V-0. 3240 epoxy glass fiber board ilibe zinthu zoletsa moto.

Kusiyanitsa 2: Mtundu wonyezimira.

Mtundu wa FR4 ndi wachilengedwe kwambiri, pang’ono yade, ndipo mtundu wa 3240 epoxy fiberglass board ndiwowoneka pang’ono. Sikuwoneka mwachilengedwe. Mitundu yambiri siili yofanana kwambiri.

Kusiyana kwachitatu: FR4 ilibe ma radiation ndipo ndi yogwirizana ndi chilengedwe.

3240 epoxy glass fiber board ili ndi halogen, yomwe simakonda kwambiri chilengedwe komanso thupi la munthu. Komanso sizikugwirizana ndi ndondomeko ya chitukuko chokhazikika cha dziko. Gulu la FR4 epoxy glass fiber board ndilosiyana.

Kusiyanitsa 4: FR4 ili ndi mawonekedwe okhazikika bwino.

FR4 imakhala yokhazikika bwino kuposa 3240, ndipo panthawi yokakamiza, kulolerana kwa makulidwe a FR4 ndikwabwinoko kuposa 3240, komwe kuli koyenera kukonzedwa.

Kusiyanitsa kwachisanu: FR4 imatha kuzimitsa yokha pamoto.

FR4 imatha kuzimitsidwa mwachilengedwe moto.

Kusiyana kwachisanu ndi chimodzi: kuyamwa kwamadzi otsika.

Kutengera kwake kwamadzi (D-24/23, makulidwe amphira 1.6mm): ≤19mg, yomwe imapereka chithandizo chabwino pakugwiritsa ntchito ma transformer onyowa ndi zida zina.

Chifukwa FR-4 epoxy glass fiber board ili ndi ntchito yabwino kwambiri, tsopano imagwiritsidwa ntchito ngati zida zotsekera m’mafakitale amagetsi ndi zamagetsi. Zachidziwikire, bolodi la 3240 epoxy fiberglass likadali ndi msika wina chifukwa cha mtengo wake.
