Standard FR4 PCB: When it works, when it fails. Learn to balance cost, thermal limits, and avoid prototype failures with proper material selection.

Specify and source Aluminum PCBs confidently: guide covers thermal management, dielectric specs, DFM, and vendor selection for high-power applications.

Struggling to choose between CEM-1 and FR4 PCB? Learn when to specify each substrate to balance cost, reliability, and layer count for your design.

FR-4 (Glass fiber epoxy resin)Features:FR-4 is a glass fiber fabric reinforced epoxy resin with a medium dielectric constant (Dk 4.5-5.5), low dielectric loss (Df 0.02-0.03), high mechanical strength (bending strength ≥400 MPa), and UL94 V-0 flame retardancy.Advantages:Low cost: Material cost is 50%

Have you ever wondered which PCB material is best for your project? FR4 and Aluminum PCBs are both popular, but each offers unique advantages. In this article, we will discuss the key differences, performance factors, and applications of both materials.
