1. FR-4 meafaitino e taugofie nai lo Rogers mea

2. O mea a Rogers e maualuga le tele o taimi fa'atusatusa i mea FR-4.

3. O le Df poʻo le faʻaleagaina o mea o le FR-4 e maualuga atu nai lo mea a Rogers, ma e sili atu le gau o faʻailoga.

4. E tusa ai ma le faʻamautuina o le impedance, o le Dk value range of Rogers material e sili atu nai lo le FR-4 material.

5. Mo le dielectric tumau, o le Dk o le FR-4 e tusa ma le 4.5, lea e maualalo ifo nai lo le Dk o Rogers mea (e uiga i le 6.15 i le 11).

6. E tusa ai ma le puleaina o le vevela, o meafaitino a Rogers e itiiti ifo le suiga pe a faʻatusatusa i mea FR-4

Aisea e fa'aaoga ai Rogers PCB mea?

FR-4 mea e maua ai le tulaga masani mo PCB substrates, tausia se paleni lautele ma lelei i le va o tau, umi, faatinoga, gaosiga, ma meatotino eletise.Ae ui i lea, talu ai o le faʻatinoga ma mea eletise e taua tele i lau mamanu, o mea a Rogers e ofoina atu faʻamanuiaga nei:

1. Maualalo eletise eletise gau

2. Tau-lelei gaosiga PCB

3. Maualalo dielectric gau

4. Pulea lelei le vevela

5. O le lautele o le Dk (dielectric constant) tau'(2.55-10.2)

6. Maualalo outgassing i aerospace talosaga

7. Faʻaleleia le pulea o le impedance
