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.
✔ 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:
♦ 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.
