1. Lisebelisoa tsa FR-4 li theko e tlaase ho feta lisebelisoa tsa Rogers

2. Lintho tsa Rogers li na le maqhubu a phahameng ha li bapisoa le lisebelisoa tsa FR-4.

3. The Df kapa dissipation factor ea FR-4 e phahame ho feta ea Rogers, 'me tahlehelo ea pontšo e kholoanyane.

4. Mabapi le botsitso ba impedance, tekanyo ea Dk ea lisebelisoa tsa Rogers e kholo ho feta ea FR-4.

5. Bakeng sa kamehla ea dielectric, Dk ea FR-4 e ka bang 4.5, e leng ka tlaase ho feta Dk of Rogers material (hoo e ka bang 6.15 ho 11).

6. Mabapi le tsamaiso ea mocheso, lisebelisoa tsa Rogers li fetoha tse fokolang ha li bapisoa le lisebelisoa tsa FR-4

Hobaneng u sebelisa lisebelisoa tsa Rogers PCB?

Lisebelisoa tsa FR-4 li fana ka maemo a mantlha bakeng sa li-substrates tsa PCB, ho boloka tekano e pharaletseng le e sebetsang lipakeng tsa litšenyehelo, ho tšoarella, ts'ebetso, tlhahiso le thepa ea motlakase. Leha ho le joalo, kaha ts'ebetso le thepa ea motlakase li bapala karolo ea bohlokoa moralong oa hau, lisebelisoa tsa Rogers li fana ka melemo e latelang:

1. Tahlehelo e tlase ea pontšo ea motlakase

2. Tlhahiso ea PCB e nang le litšenyehelo

3. Tahlehelo e tlase ea dielectric

4. Tsamaiso e ntle ea mocheso

5. Mefuta e mengata ea litekanyetso tsa Dk (dielectric constant)..(2.55-10.2)

6. Khaello e tlase ea khase lits'ebetsong tsa sefofane

7. Ntlafatsa taolo ea impedance
