Ukuqaliswa kwezixhobo zeFR4

I-FR kwi-FR4 imele i-flame retardant, kunye nenombolo ye-4 iyahlula izinto ezivela kwezinye izinto ezikulo klasi.I-FR4 yi-fiber yeglasi eqiniswe i-epoxy laminate ekhangeleka njengephepha elincinci elilukiweyo.Igama elithi FR4 likwamele ibakala elisetyenziselwa ukwenza ezi laminates.Isakhiwo se-fiberglass sibonelela ngokuzinza kwesakhiwo kwizinto eziphathekayo.Ifiber yeglasi yogqunywe yi-epoxy ye-flame retardant.Oku kunika ukuqina kwezinto eziphathekayo kunye neempawu ezinamandla zoomatshini.Zonke ezi mpawu zenza ibhodi yesekethe eprintiweyo yeFR4 idume kakhulu phakathi kwabavelisi bekhontrakthi ye-elektroniki.
