1. ʻOi aku ka liʻiliʻi o nā mea FR-4 ma mua o nā mea Rogers

2. He kiʻekiʻe ke alapine ʻo Rogers i hoʻohālikelike ʻia me ka mea FR-4.

3. ʻOi aku ka kiʻekiʻe o ka Df a i ʻole dissipation factor o ka mea FR-4 ma mua o ka mea Rogers, a ʻoi aku ka nui o ka nalowale o ka hōʻailona.

4. Ma keʻano o ka impedance stability,ʻoi aku ka nui o ka helu Dk waiwai o Rogers ma mua o ka mea FR-4.

5. No ka mau dielectric, ʻo ka Dk o FR-4 ma kahi o 4.5, ʻoi aku ka haʻahaʻa ma mua o ka mea Dk o Rogers (ma kahi o 6.15 a 11).

6. Ma ke ʻano o ka hoʻokele wela, ʻoi aku ka liʻiliʻi o nā mea Rogers i hoʻohālikelike ʻia me ka mea FR-4

No ke aha e hoʻohana ai i nā mea PCB Rogers?

Hāʻawi nā mea FR-4 i ka maʻamau maʻamau no nā substrates PCB, e mālama ana i kahi kaulike ākea a maikaʻi ma waena o ke kumukūʻai, ka lōʻihi, ka hana, ka hana ʻana, a me nā waiwai uila. Eia nō naʻe, no ka mea he mea koʻikoʻi ka hana a me nā waiwai uila i kāu hoʻolālā, hāʻawi nā mea Rogers i kēia mau pono:

1. Haʻahaʻa uila hōʻailona poho

2. Uku-pono PCB hana

3. Haʻahaʻa dielectric poho

4. ʻOi aku ka maikaʻi o ka hoʻokele wela

5. Ka laula nui o Dk (dielectric mau).ʻ(2.55-10.2)

6. Haʻahaʻa outgassing ma aerospace noi

7. Hoʻonui i ka mana impedance
