Product Description

Two Layer PCB Board for Prototype and Mass Products

♦ What is a Two-Layer (Double-Sided) PCB?

A Two-Layer PCB (Double-Sided PCB) is a printed circuit board with two conductive copper layers—one on the top side and one on the bottom side—connected by vias (plated holes). It offers more routing flexibility than a single-layer PCB while remaining cost-effective for mid-complexity designs.

Key Features:

✔ 2 Conductive Layers – Copper traces on both sides of the board.
✔ Vias for Interconnections – Plated holes allow electrical connections between layers.
✔ Better Routing Space – More flexibility than single-layer PCBs.
✔ Moderate Cost – Cheaper than multi-layer PCBs but more expensive than single-layer.

♦ Structure of a Two-Layer PCB:

1. Substrate (Base Material) – Typically FR4 (fiberglass epoxy).
2. Top Copper Layer – Contains traces and components.
3. Bottom Copper Layer – Additional routing space.
4. Solder Mask – Protective coating (usually green) to prevent shorts.
5. Silkscreen – Printed labels for component placement.
6. Vias – Plated holes connecting top and bottom layers.

♦ Advantages of Two-Layer PCBs:

✅ More Routing Space – Better for moderately complex circuits.
✅ Improved Signal Integrity – Ground planes reduce noise (if designed properly).
✅ Cost-Effective for Mid-Range Designs – Balances performance and affordability.
✅ Widely Used – Suitable for many consumer and industrial applications.
