FR4 Double Sided Blue Oil Half Hole Plate PCB Multilayer Printed Circuit Board

 Double-sided blue oil half-hole plate

product Features:

• Two-sided wiring
• through hole connection
• component placement
• Higher circuit density

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.

• Achieved by:

  • Using two-sided or multi-layer boards

  • Smaller components (e.g., surface-mount devices)

  • Finer trace widths and spacing

• Benefits include smaller product size and improved performance.

Manufacturing process:

• Design and layout:Firstly, the PCB design is carried out through circuit design software, with wiring and component placement on both sides, and the position type of vias are planned at the same time.
• Drilling and electroplating: Drilling is carried out according to the design requirements, and electroplating is performed after drilling to form a via the circuits on both sides.
• Etching: Remove the excess copper foil to form the desired circuit pattern.
• Assembly and welding: After the components are installed, welding treatment is carried out, which can be done using surface-mount technology (SMT) or through technology (THT).
