Double-sided blue oil half-hole plate

A double-sided PCB with blue solder mask is a basic circuit board with conductive traces on both sides. Linked by plated through-holes, its blue coating shields copper from oxidation, boosts insulation, and suits compact electronics like home appliances and small gadgets for its low cost and practicality.

Main advantages:

1. Two-sided wiring

• Refers to PCBs that have conductive traces on both the top and bottom layers.

• It allows more complex circuit designs compared to single-sided boards.

• Components can be mounted on one or both sides.

• Enables better routing and efficient use of board space.

2. Through hole connection

• A method of mounting components where leads are inserted into holes drilled through the PCB and soldered on the opposite side.

• Strong mechanical bonds – ideal for components that experience stress (like connectors).

• Used on both single-sided and double-sided PCBs.

• Supports interconnection between top and bottom layers.

3. Component placement

• Refers to the strategic positioning of electronic components on a PCB.

• Affects:

  • Electrical performance

  • Heat dissipation

  • Manufacturability

  • Signal integrity

• In two-sided PCBs, placement can be done on both sides (mixed technology: SMD + through-hole).

• 4. Higher circuit density

  Means more circuitry per unit area of the PCB.
