1. Qalabka FR-4 wuu ka jaban yahay maaddada Rogers

2. Maaddada Rogers waxay leedahay soo noqnoqoshada sare marka loo eego walxaha FR-4.

3. Qodobka Df ama kala firdhinta walxaha FR-4 way ka sarreeyaan tan maaddada Rogers, khasaaraha calaamaduna wuu ka weyn yahay.

4. Marka la eego xasiloonida impedance, kala duwanaanshaha qiimaha Dk ee walxaha Rogers ayaa ka weyn kan FR-4.

5. Dielectric joogto ah, Dk ee FR-4 waa qiyaastii 4.5, kaas oo ka hooseeya Dk ee walxaha Rogers (qiyaastii 6.15 ilaa 11).

6. Marka la eego maareynta heerkulka, walxaha Rogers wax yar ayaa isbeddelaya marka la barbardhigo walxaha FR-4

Waa maxay sababta loo isticmaalo qalabka PCB ee Rogers?

Qalabka FR-4 waxay bixiyaan heerka aasaasiga ah ee substrate-ka PCB, iyagoo ilaalinaya dheelitirnaan ballaaran oo wax ku ool ah oo u dhexeeya qiimaha, adkeysiga, waxqabadka, wax soo saarka, iyo guryaha korantada. Si kastaba ha noqotee, maadaama waxqabadka iyo guryaha korantada ay door muhiim ah ka ciyaaraan naqshaddaada, agabyada Rogers waxay bixiyaan faa'iidooyinka soo socda:

1. Khasaar koronto oo hooseeya

2. Wax-soo-saarka PCB-ga ee wax-ku-oolka ah

3. Khasaaraha dielectric hooseeya

4. Maamulka kulaylka oo wanaagsan

5. Kala duwanaansho ballaaran oo Dk ah (dielectric joogto ah) qiyamka;(2.55-10.2)

6. Gaadhis hooseeya ee codsiyada hawada sare

7. Hagaajinta xakamaynta impedance
