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 Rogers PCB?

Qalabka FR-4 waxay bixiyaan heerka aasaasiga ah ee substrates PCB, ilaalinta dheelitirnaanta ballaaran oo waxtarka leh ee u dhexeeya qiimaha, adkeysiga, waxqabadka, wax soo saarka, iyo guryaha korontada.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 wax-ku-ool 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
