FR4 Rigid Epoxy Glassfiber Laminated Sheet
Product Description
Ichi chigadzirwa chaive chakashongedzwa nekupisa kwepamusoro uye kudzvanywa kwemagetsi egirazi fiber jira rakaiswa nebrominated epoxy resin.Iyo ine yakakwira mechanical zvivakwa, dielectric zvivakwa uye murazvo unodzoreredza zvivakwa, zvakare nekunaka kwekupisa uye kudzivirira hunyoro;
FR-4 ikodhi yegiredhi rezvinhu zvinodzivirira murazvo, izvo zvinoreva chirevo chechinhu icho resin zvinhu zvinofanirwa kukwanisa kudzima yega mushure mekupisa. Harisi zita rezvinhu, asi giredhi rezvinhu. Zita rekuti FR4 rinobva kuNEMA grading system uko'FR'inomirira'moto retardant', inoenderana neUL94V-0 standard. Naizvozvo, general PCB wedunhu mabhodhi, Kune akawanda marudzi eFR-4 giredhi zvinhu zvinoshandiswa, asi mazhinji acho ari musanganiswa zvinhu zvakagadzirwa neTera-Function epoxy resin ine filler uye girazi fiber.
Kutevedzera Mipimo
Zvinoenderana neGB/T 1303.4-2009 yemagetsi thermosetting resin indasitiri yakaoma laminates - Chikamu 4: epoxy resin yakaoma laminates, IEC 60893-3-2-2011 insulating zvinhu - yemagetsi thermosetting resin indasitiri yakaoma laminates - Chikamu 3-2 chemunhu ega zvinyorwa EPGC202.
