FR4 Hazvichinji-chinji Epoxy Glassfiber Laminated Sheet
Chigadzirwa Chigadzirwa
Ichi chigadzirwa chakarongedzwa neakanyanya tembiricha uye yakanyanya kumanikidza nemagetsi glassfiber jira rakaisirwa ne brominated epoxy resin.Iine yakakwira michina zvivakwa, dielectric zvivakwa uye murazvo unodzora zvivakwa, zvakare ine yakanaka kupisa kuramba uye mwando kuramba;
FR-4 kodhi yegiredhi remidziyo isingagadzike zvinhu, zvinoreva chinhu chakatsanangurwa kuti resin zvinhu zvinofanirwa kukwanisa kudzima pachezvayo mushure mekutsva. Haisi zita rezvinhu, asi giredhi rezvinhu. Iro zita FR4 rinouya kubva kuNEMA grading system uko iyo‘FR’ inomirira ‘kudzora moto’, inoenderana neiyo UL94V-0 yakajairwa. Naizvozvo, mabhodhi ePCB akajairika, Kune akawanda marudzi eF-4 giredhi zvinhu zvinoshandiswa, asi mazhinji acho zvinhu zvinoumbwa zvakagadzirwa neTera-Rinoshanda epoxy resin ine filler uye girazi faibha.
Kuteerera neMitemo
Zvinoenderana neGG / T 1303.4-2009 yemagetsi thermosetting resin maindasitiri akaoma laminates - Chikamu 4: epoxy resin yakaoma laminates, IEC 60893-3-2-2011 inodzivirira zvinhu - magetsi thermosetting resin maindasitiri akaomarara akaomeswa - Chikamu 3-2 cheicho chinhu tsananguro EPGC202.
Zvimiro
1.High zvemaziso zvivakwa;
2.High dielectric zvivakwa;
3.Good Mechinability
4.Good mwando kuramba;
5.Good kupisa kuramba;
6.Temperature kuramba: Giredhi B, 130℃
7.Flame retardant chivakwa: UL94 V-0
Kushanda
Ichi chigadzirwa chinonyanya kushandiswa seyakagadzika zvikamu zveMota nemidziyo yemagetsi, kusanganisira marudzi ese echinja, michina yemagetsi, FPC yekusimbisa ndiro, kabhoni firimu rakadhindwa wedunhu mabhodhi, komputa yekuchera pad, furu uye yekunyungudisa michina (PCB bvunzo murazvo ame; uye zvakare yakakodzera pasi penzvimbo nyoro uye oiri yema transformer.
