Umahluko phakathi kwe-FR-4 Material kunye neRogers Material

1. Izinto ze-FR-4 zinexabiso eliphantsi kunezinto zikaRogers

2. Izinto ze-Rogers zine-frequency ephezulu xa kuthelekiswa ne-FR-4 impahla.

3. I-Df okanye i-dissipation factor ye-FR-4 iphezulu kuneyona nto ye-Rogers, kwaye ilahleko yesignali inkulu.

4. Ngokubhekiselele kwi-impedance stability, ixabiso le- Dk lezinto eziphathekayo zeRogers likhulu kunelo le-FR-4.

5. Kwi-dielectric constant, i- Dk ye-FR-4 i malunga ne-4.5, ephantsi kune- Dk ye-Rogers impahla (malunga ne-6.15 ukuya kwi-11).

6. Ngokumalunga nokulawulwa kweqondo lokushisa, izinto zeRogers zitshintsha ngaphantsi xa kuthelekiswa ne-FR-4

 

Kutheni usebenzise izixhobo zePCB zikaRogers?

Izinto ze-FR-4 zibonelela ngomgangatho osisiseko we-PCB substrates, ukugcina ibhalansi ebanzi nesebenzayo phakathi kweendleko, ukuqina, ukusebenza, ukwenziwa, kunye neempawu zombane. Nangona kunjalo, kuba ukusebenza kunye neepropathi zombane zidlala indima ebalulekileyo kuyilo lwakho, izixhobo zeRogers zibonelela ngezi zibonelelo zilandelayo:

1. Ukulahleka komqondiso ophantsi wombane

2. Imveliso yePCB enexabiso eliphantsi

3. Ilahleko ye-dielectric ephantsi

4. Ulawulo olungcono lwe-thermal

5. Uluhlu olubanzi lwee-Dk (dielectric constant) amaxabiso.(2.55-10.2)

6. Ukukhutshwa kwegesi okuphantsi kwizicelo ze-aerospace

7. Ukuphucula ulawulo lwe-impedance
