FR-4 PCB

FR-4 PCB waxaa loola jeedaa Guddiga Wareegga Daabacan (PCB) ee u isticmaala walxaha FR-4 sida substrate-keeda. FR-4 waa walxo isku dhafan oo caan ah oo loo isticmaalo wax soo saarka PCB. Magaceeda oo buuxa waa Flame Retardant 4, taasoo muujinaysa inay la kulmeyso qiimeyn gaar ah oo dib u dhac olol ah. Maaddadani waxay ka kooban tahay maro fiberglass ah oo tolan oo ay ku jirto resin epoxy, oo bixisa sifooyin koronto oo wanaagsan, xoog farsamo, iyo dib u dhac olol.

Waa kuwan qaar ka mid ah sifooyinka muhiimka ah ee FR-4 PCB:

● Dib u dhaca ololka

● Waxqabadka Korontada

● Xoogga Makaanikada

● Waxqabadka kulaylka

● Waxtarka-kharashka
