9x15 cm Double-Side Copper Prototype PCB (1 Pc)

9x15 cm Double Side Copper Prototype PCB Universal Board for Arduino

The 9x15 cm double-side copper prototype PCB is an essential component for hardware developers, engineering students, and electronics hobbyists across Bangladesh. Designed for rapid circuit prototyping and testing, this universal perfboard provides a stable platform to build permanent or semi-permanent circuits without the expense of custom PCB manufacturing. Whether you are assembling a custom microcontroller development setup or sourcing reliable electronics parts from Biggan Project, this high-density matrix board offers the space and conductivity required for clean circuit wiring.

Featuring a dual-layer copper construction protected by a durable green solder mask, this universal board allows for intricate routing, cross-connections, and component placement on both sides. The pre-drilled precision holes, set at a standard 0.1-inch (2.54mm) pitch with a minimum hole diameter of 0.06 inches, accommodate standard IC sockets, DIP chips, headers, and passive components. Engineers and students working on BD science projects can easily solder components, run jumper wires, and construct durable electronic prototypes ready for deployment.

Features

• Dual-Layer Copper Traces: Double-sided pads allow soldering on either face, making complex trace routing easier.
• Pre-Tinned Through-Holes: Plated-through holes ensure strong mechanical support and efficient solder flow.
• Standard Hole Grid: 2.54mm pitch layout guarantees full compatibility with standard ICs, headers, and breakout modules.
• Durable FR-4 Substrate: Provides excellent heat resistance during soldering and high physical rigidity.
• Precision Drilling: 0.06-inch holes handle standard component leads, wire jumpers, and header pins smoothly.
• Corner Mounting Holes: Pre-drilled corner holes make it simple to secure the PCB inside enclosures or project chassis.

Applications / Use Cases

• Arduino & Microcontroller Prototyping: Building custom shields and expanding development boards.
• DIY Science Projects: Assembling robotics controls, sensor interfaces, and automation circuits for school or university projects in BD.
• Circuit Testing & Proofing: Transitioning temporary breadboard concepts into permanent, soldered hardware designs.
• Custom Power Supply Modules: Mounting voltage regulators, capacitors, and terminal blocks on a compact base.
• Sensor Integration: Connecting multiple sensor modules, displays, and communication chips on a single board.

User Guide / How to Use

• Plan Your Layout: Map out component placement and connection paths on paper or software before soldering.
• Insert Components: Push component leads through the top side of the board into the designated hole matrix.
• Solder Connections: Apply a heated soldering iron tip and solder to the copper ring on the bottom or top layer to secure each pin.
• Create Traces: Bridge adjacent pads using solder bridges or solder insulated jumper wires for longer connections.
• Trim Excess Leads: Use flush wire cutters to clip component leads close to the soldered joints.
• Inspect the Board: Check all joints with a multimeter in continuity mode to prevent accidental short circuits between adjacent pads.

Frequently Asked Questions (FAQs)

• Q: Is this board compatible with standard breadboard components?
  A: Yes, the 2.54mm hole pitch directly matches breadboard pin spacing, accepting standard headers, DIP chips, and passive components.
• Q: Can I cut or trim this board to a smaller size?
  A: Yes, the FR-4 material can be cut or scored using a utility knife, PCB shears, or a fine saw to fit smaller project enclosures.
• Q: Are the pads connected in rows like a solderless breadboard?
  A: No, this is a universal matrix board with individual plated holes, giving you complete flexibility to route custom connections.
• Q: Are the holes plated through from top to bottom?
  A: Yes, the holes are plated-through (PTH), allowing electrical continuity between the top and bottom copper layers.

Challenges and Considerations

• Manual Routing Required: Since pads are isolated, you must manually bridge pins or use hookup wire to build circuit paths.
• Overheating Caution: Excessive heat or prolonged iron contact can lift the copper pad from the substrate; maintain correct soldering temperatures.
• Dust During Cutting: Wear protective glasses and a mask if cutting the FR-4 fiberglass material to prevent inhaling fine dust.

Compatibility

• Compatible with Arduino Uno, Nano, Mega, and ESP32 expansion setups.
• Fits standard 2.54mm male and female pin headers, DIP IC sockets, and terminal blocks.
• Suitable for standard electronic components including resistors, capacitors, transistors, LEDs, and diodes.
• Ideal for custom enclosure integration in robotics and automation projects built in Bangladesh.

Future Enhancement Options

• Add screw terminal blocks to the edge of the board for easy external power and sensor wiring.
• Install female header strips to create swap-capable socket slots for microcontrollers and sensors.
• Mount brass standoffs in the corner holes for clean installation into custom 3D-printed or acrylic enclosures.
• Apply insulating conformal coating on finished soldering paths for environmental protection.

Benefits

• Provides a low-cost, professional method to transform temporary breadboard designs into solid, permanent circuits.
• High-density 9x15 cm surface area offers ample space for complex multi-component builds.
• Double-sided copper layout doubles working surface area for cleaner wire management.
• Extremely durable structure prevents loose wiring failures common in breadboard setups.
