Single-sided PCB Overview
The Single-sided PCB is a fundamental componente in electronic manufacturing, offering a simple yet effective platform for the assembly of componentes electronicos. 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 materiales 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 (Alabama): 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.
