Single-sided PCB Overview

The Single-sided PCB is a fundamental component in electronic manufacturing, offering a simple yet effective platform for the assembly of electronic components. It features a single layer of conductive copper circuitry etched onto a non-conductive substrate, making it ideal for a range of applications where complexity is not a primary requirement.

Composición de materiales

The Single-sided PCB is crafted from various materials to cater to different needs:

CEM-1: Combines paper and epoxy resin for cost-effectiveness and moderate durability.
CEM-3: Utilizes glass fiber and epoxy resin for enhanced mechanical strength and electrical insulation.
FR-4: Known for its flame retardant properties and high glass transition temperature, suitable for demanding applications.
Aluminio (Al): Offers exceptional thermal conductivity, making it ideal for heat dissipation in high-power circuits.
poliimida (PI): Provides flexibility and durability, suitable for applications requiring bending or conformability.
