1. Zinthu za FR-4 ndizotsika mtengo kuposa za Rogers

2. Rogers zakuthupi zimakhala ndi maulendo apamwamba poyerekeza ndi zinthu za FR-4.

3. Df kapena dissipation factor of FR-4 material is high than the Rogers material, ndipo kutaya kwa chizindikiro kumakhala kwakukulu.

4. Ponena za kukhazikika kwa impedance, mtengo wa Dk wa zinthu za Rogers ndi zazikulu kuposa za FR-4.

5. Kwa dielectric constant, Dk ya FR-4 ili pafupi 4.5, yomwe ili yochepa kuposa Dk ya Rogers (pafupifupi 6.15 mpaka 11).

6. Ponena za kayendetsedwe ka kutentha, zinthu za Rogers zimasintha pang'ono poyerekeza ndi FR-4 zinthu

Chifukwa chiyani mumagwiritsa ntchito zida za Rogers PCB?

Zipangizo za FR-4 zimapereka mulingo woyambira wa magawo a PCB, kukhala ndi malire otakata komanso ogwira mtima pakati pa mtengo, kulimba, magwiridwe antchito, kupanga, ndi mphamvu zamagetsi. Komabe, popeza magwiridwe antchito ndi magetsi amatenga gawo lofunikira pakupanga kwanu, zida za Rogers zimapereka zabwino izi:

1. Kutayika kwa chizindikiro chochepa cha magetsi

2. Kupanga kwa PCB kotsika mtengo

3. Kutayika kwa dielectric kochepa

4. Kuwongolera bwino kwa kutentha

5. Zambiri za Dk (dielectric constant) zikhalidwepa(2.55-10.2)

6. Kutsika kwa mpweya muzamlengalenga

7. Sinthani kuwongolera kwa impedance
