Epoxy Fiberglass Sheet Fr4 Sheet G10 isina kupfeka laminate Sheet ine Hunhu Hwakanaka hweMechanical uye Electrical Insulating
Tsananguro yeChigadzirwa
Chigadzirwa ichi chakaputirwa nekupisa kwakanyanya uye kumanikidzwa kwakanyanya nejira remagetsi regirazi rakazadzwa ne epoxy resin ine brominated. Chine hunhu hwepamusoro hwemakanika, hunhu hwe dielectric uye hunhu hwemurazvo, uye chinodzivirira kupisa zvakanaka uye hunhu hwehunyoro;
FR-4 ikodhi yemhando yezvinhu zvinodzivirira moto, zvinoreva chimiro chezvinhu chinofanira kudzima chega kana chatsva. Harisi zita rezvinhu, asi rudzi rwezvinhu. Zita rekuti FR4 rinobva kuNEMA grading system uko'FR'inomirira'chinhu chinodzivirira moto', inoenderana ne UL94V-0 standardSaka, mabhodhi ePCB edunhu akajairika, Kune mhando dzakawanda dzezvinhu zveFR-4 zvinoshandiswa, asi mazhinji acho zvinhu zvakagadzirwa neTera-Function epoxy resin ine filler negirazi fiber.
Kutevedzera Maitiro
Zvichienderana neGB/T 1303.4-2009 electrical thermosetting resin industrial hard laminates - Chikamu 4: epoxy resin hard laminates, IEC 60893-3-2-2011 insulating materials - electrical thermosetting resin industrial hard laminates - Chikamu 3-2 che EPGC202.
Zvinhu zvirimo
1. Hunhu hwepamusoro hwemakanika;
2. Hunhu hwepamusoro hwe dielectric;
3.Kugona Kushanda Zvakanaka
4.Kudzivirira hunyoro hwakanaka;
5. Kudzivirira kupisa kwakanaka;
6. Kudzivirira kupisa: Giredhi B
7.Inodzivirira moto: UL94 V-0
Kushandiswa
Chigadzirwa ichi chinonyanya kushandiswa sezvikamu zvechivakwa cheMotor nemidziyo yemagetsi, kusanganisira marudzi ese eswitch、midziyo yemagetsi、FPC simbiso ndiro、mabhodhi edunhu akadhindwa efirimu recarbon、pedhi rekubhoridha makomputa、michina yekunyungudutsa nekunyungudutsa (PCB test fire)）uye zvakare yakakodzera munzvimbo ine mvura uyemafuta etransformer.
