Green Oil Electronic Double Sided Rigid PCB Board Customized Design

High-Quality Double-Sided Printed Circuit Boards

Double-sided PCB, also known as double-sided printed circuit board, is a printed circuit board (PCB) with two-sided circuit connections. In this kind of PCB, the electronic components and circuit layout can be arranged on both sides of the PCB respectively, and the electrical connection of the circuits on both sides is achieved through vias (Vias). This structure greatly increases the functional density of the circuit board, allowing it to implement more circuit connections in a relatively small area.

What documents are required for ordering custom double-sided PCBs?

Please send us your:
1. Gerber files (RS-274X)
2. BOM (if PCBA needed)
3. Impedance requirements & stack-up (if available)
4.Test requirements (TDR, network analyzer, etc.)

The information that needs to be included in the Gerber file:Number of layers, board material, board thickness, copper thickness, surface finish, solder mask and silkscreen color, quantity, etc.

We’ll reply within 24 hours with a free quote, DFM report, and material recommendation.

The main challenges in Double-sided PCB manufacturing

1. Interlayer Alignment Precision

• Double-sided PCBs require precise alignment between the top and bottom layers to ensure the accuracy of via connections. Even minor misalignment can lead to open circuits or short circuits.
• The manufacturing process, including lamination and drilling, is highly sensitive to temperature and pressure changes, which can easily affect the alignment of the two layers.

2. Solder Mask Coating Uniformity

• Applying solder mask on both sides demands consistent thickness and coverage. Uneven coating may cause poor insulation or difficulty in soldering components later.
• The curing process for the solder mask on both sides needs strict parameter control; improper curing can lead to peeling or cracking of the mask layer.

3. Double-Sided Assembly Complexity

• During component mounting, the weight and heat of components on one side may affect the stability of the other side, increasing the risk of component displacement or solder joint failure.
• Testing for double-sided PCBs is more complex than for single-sided ones, as it requires verifying the functionality of both layers and the integrity of interlayer vias, which raises testing costs and difficulty.
