FR4 Epoxy Fiberglass Laminated Sheet
Malangizo a Zamalonda
Chogulitsachi chinapangidwa ndi kutentha kwambiri komanso kuthamanga kwambiri ndi nsalu yamagetsi yagalasi yodzazidwa ndi epoxy resin yokhala ndi brominated. Chili ndi mphamvu zambiri zamakanika, mphamvu za dielectric komanso mphamvu zoletsa moto, komanso chimakhala ndi mphamvu zabwino zoteteza kutentha komanso chinyezi;
FR-4 ndi code ya mtundu wa zinthu zosagwira moto, zomwe zikutanthauza mfundo ya zinthu zomwe utomoni uyenera kuzimitsa wokha ukayaka. Si dzina la zinthu, koma mtundu wa zinthu. Dzina lakuti FR4 limachokera ku dongosolo la NEMA lowerengera komwe 'FR' imayimira 'woletsa moto', mogwirizana ndi muyezo wa UL94V-0.
Kutsatira miyezo
Mogwirizana ndi GB/T 1303.4-2009, ma laminates olimba a thermoset resin amagetsi - Gawo 4: ma laminates olimba a epoxy resin, IEC 60893-3-2-2011, zotetezera - ma laminates olimba a thermoset resin amagetsi - Gawo 3-2 la zomwe zafotokozedwa payokha pa EPGC202.
Kugwiritsa ntchito
Chogulitsachi chimagwiritsidwa ntchito makamaka ngati zida zomangira zamagetsi ndi zamagetsi, kuphatikiza mitundu yonse ya switch, zida zamagetsi, mbale yolimbikitsira ya FPC, ma board ozungulira osindikizidwa ndi filimu ya kaboni, pad yobowola makompyuta, zida zoumba ndi zosungunulira (lawi loyesera la PCB); komanso yoyenera pansi pa malo onyowa komanso mafuta osinthira.

FAQ
Q1: Kodi mukuchita malonda ndi kampani kapena wopanga?
Ndife opanga otsogola opanga zinthu zotetezera magetsi, takhala tikugwira ntchito ndi opanga zinthu zoteteza kutentha kuyambira mu 2003. Mphamvu yathu ndi 6000TONS pachaka.
Q2: Zitsanzo
Zitsanzo ndi zaulere, muyenera kungolipira ndalama zotumizira.
Q3: Kodi mumatsimikiza bwanji kuti kupanga zinthu zambiri kudzakhala bwino?
Kuti muwone mawonekedwe, kukula ndi makulidwe: tidzayang'anitsitsa zonse tisanapake.
Kuti tigwire bwino ntchito: Timagwiritsa ntchito njira yokhazikika, ndipo tidzayang'anira zitsanzo nthawi zonse, titha kupereka lipoti loyang'anira zinthu tisanatumize.
Q4: Nthawi yotumizira
Zimatengera kuchuluka kwa oda. Nthawi zambiri, nthawi yotumizira idzakhala masiku 15-20.
Q5: Phukusi
Tidzagwiritsa ntchito pepala laukadaulo poyika pa plywood pallet. Ngati muli ndi zofunikira zapadera pa phukusi, tidzayika malinga ndi zosowa zanu.
Q6: Malipiro
TT, 30% T/T pasadakhale, ndalama zonse musanatumize. Timalandiranso L/C.
