PCB-ga FR-4

PCB-ga FR-4 waxa uu tilmaamayaa Guddi Wareeg ah oo Daabacan (PCB) kaas oo u adeegsada walxaha FR-4 sida substrate-kiisa. FR-4 waa walxo isku-dhafan oo aad caadi u ah oo loo isticmaalo wax-soo-saarka PCB-ga. Magaciisa oo buuxa waa Flame Retardant 4, taasoo muujinaysa inay buuxiso qiimeyn gaar ah oo dab-damis ah. Maaddadani waxay ka kooban tahay maro fiberglass ah oo la tolay oo lagu dahaadhay resin epoxy, taasoo bixisa sifooyin dahaadh koronto oo wanaagsan, xoog farsamo, iyo dab-damis.

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

● Daahitaanka Ololka

● Waxqabadka Korantada

● Xoogga Farsamada

● Waxqabadka Kulaylka

● Kharashka-waxtarka leh
