Horudhaca agabka FR4
FR gudaha FR4 waxay u taagan tahay dab-demiska, nambarka 4-na wuxuu ka soocaa walxaha iyo walxaha kale ee fasalkan. FR4 waa fiber galaas ah oo la xoojiyay epoxy laminate oo u eg xaashi khafiif ah oo tolan.Erayga FR4 waxa kale oo uu ka dhigan yahay darajada loo isticmaalo samaynta laminates-kan.Qaab dhismeedka fiberglass-ku wuxuu bixiyaa xasilloonida qaabdhismeedka maaddada.Fiberka dhalada waxa lagu daboolay epoxy ololka celinaya.Tani waxay siinaysaa adkeysiga maaddada iyo sifooyinka farsamada ee xooggan.Dhammaan sifooyinkan ayaa ka dhigaya guddiga wareegga daabacan ee FR4 mid aad caan uga ah soosaarayaasha qandaraasyada elektiroonigga ah.
Sidee FR4 loogu habeeyey looxyada wareegyada daabacan ee caadiga ah ee FR4?FR4 waxay u adeegtaa sidii aasaaska PCB kasta.Qalabka waxaa lagu dhejiyay bireed naxaas ah.Isticmaal kulaylka iyo koolada si aad u dahaadhiso.Foornada naxaasta ah waxaa loo isticmaali karaa in lagu dhejiyo walxaha hal ama labada dhinacba.
