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.

材料構成

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.
アルミニウム (Al): Offers exceptional thermal conductivity, making it ideal for heat dissipation in high-power circuits.
ポリイミド (PI): Provides flexibility and durability, suitable for applications requiring bending or conformability.

性能特性

These boards are designed with specific performance attributes:

Layer Configuration: 1層, simplifying the design and manufacturing process.
カラーオプション: Available in white, 黒, blue, or green, allowing for aesthetic customization.
厚さ: Finished thickness ranges from 0.6mm to 1.6mm, accommodating various component heights and packaging requirements.
銅の厚さ: Copper thickness of 0.5OZ to 2OZ supports various current carrying capacities and circuit densities.

構造設計

構造的に, the Single-sided PCB comprises:

Base Material: The substrate that supports the copper circuitry.
銅箔: Etched to form the circuit pattern.
Surface Finish: OSP (Organic Solderability Preservative) treatment ensures good solderability and protects the copper from oxidation.

特徴的な機能

Key features that distinguish Single-sided PCBs include:

最小トレース/スペース: Minimum trace and space of 12mil enable high-density routing, crucial for compact designs.
