What is the difference between Rogers PCB and ordinary PCB?

Compare with ordinary PCB, Rogers PCB is widely used in high frequency and high reliability fields such as microwave communication, 5G, military radar, etc. Furthermore, Rogers PCB is a high-performance PCB, which means: 1.Good rigidity, mechanical and electrical properties, easy to hole metallization; 2.High precision of board thickness; 3.Awesome copper adhesion, high heat dissipation capacity, perfect peel strength, no layering and foam; 4.Be compatible with FR-4 processing technology except the higher cost of Rogers board itself. PS: Rogers PCB is the most stable material in the industry, with low dielectric loss and low water absorption. In addition, its dielectric constant (DK) is stable with [...]

FR4 Material for Fabrication of Printed Circuit Boards

FR4 is a glass epoxy laminate sheet that is most commonly used in PCBs Fabrication (Printed Circuit Boards). It is used in all kinds of flexible printed circuit boards, and other semi-rigid PCB variants. It displays excellent properties of high strength and flame resistance among others. The ease of integration in applications and allowance of component mounting has made it a preferred material in most PCBs.   Production Process of FR4 Fiberglass sheets are impregnated with epoxy resin. These sheets are used to construct FR4. Eight of these reinforced sheets are covered with a copper foil layer. This entire construction [...]
