4x6cm Double Side FR4 Veroboard Prototype PCB 1.5mm

4x6 cm FR4 Glass Fiber Double Sided Universal Prototype PCB Board

The 4x6cm Double Side FR4 Veroboard is an essential prototyping platform designed for electronics hobbyists, students, and engineers across Bangladesh. Built from durable FR4 glass fiber, this universal prototype PCB features plated through-holes on both sides with a standard 2.54mm pitch grid, making it fully compatible with DIP integrated circuits, headers, and standard electronic components. Whether you are assembling a DIY science project, testing sensor modules, or building custom embedded hardware, this board provides superior structural integrity and reliable electrical connectivity compared to standard paper-based phenolic boards. It is widely used by makers in BD for turning breadboard prototypes into permanent, robust circuits.

Specifications

Features

• High-density FR4 glass fiber construction prevents warping and withstands high soldering temperatures.
• Plated through-holes (PTH) allow strong mechanical solder joints and seamless dual-sided connections.
• Standard 2.54mm grid pitch allows direct mounting of IC sockets, pin headers, and microcontrollers.
• Identical pads on both sides enable flexible trace routing and compact circuit layouts.
• Pre-drilled mounting corner holes assist in securely mounting the board inside project enclosures.

Applications / Use Cases

• Building permanent circuits for Arduino, ESP32, and Raspberry Pi DIY projects in Bangladesh.
• Developing custom sensor breakout boards and relay modules for robotics applications.
• Constructing power supply circuits, voltage regulators, and motor driver boards.
• Educational electronics lab experiments, university thesis builds, and Biggan Project creations.
• Repairing or replacing broken original circuit sections in custom electronic gear.

User Guide / How to Use

• Plan your circuit layout on paper or using breadboard simulator software before placing components.
• Insert component leads through the top side and bend them slightly on the bottom to keep them in place.
• Solder component pins using a standard temperature-controlled soldering iron and quality solder wire.
• Connect circuit points using insulated jumper wires or bridge adjacent pads with small solder bridges.
• Trim excess component leads using diagonal wire cutters to prevent short circuits.

Frequently Asked Questions (FAQs)

• Q: What is the main advantage of an FR4 board over a paper PCB?
  A: FR4 glass fiber is heat-resistant, physically stronger, moisture-proof, and far less likely to delaminate or break during soldering compared to standard paper phenolic boards.
• Q: Can I cut this 4x6 cm board into smaller pieces?
  A: Yes, you can score both sides along a line using a utility knife and snap it, or cut it using a rotary tool or fine hacksaw.
• Q: Do components fit without extra drilling?
  A: Yes, the standard 0.9mm hole diameter accepts lead wires of resistors, capacitors, LEDs, transistors, and 2.54mm pin headers smoothly.
• Q: Are the top and bottom holes connected?
  A: Yes, the holes are plated through (PTH), meaning solder flows through to electrically connect pads on both sides automatically.

Challenges and Considerations

• Avoid excessive thermal exposure from prolonged soldering iron contact to prevent copper pad lifting.
• Always inspect adjacent pads using a magnifying glass to check for unintentional solder bridges.
• Wearing safety glasses is recommended when trimming component leads after soldering.

Compatibility

• Compatible with standard 2.54mm breadboard-friendly modules, microcontrollers, and pin headers.
• Fits standard DIP package ICs, transistors, resistors, LEDs, and terminal blocks.
• Works seamlessly with common soldering irons, flux cores, and standard prototyping accessories.

Future Enhancement Options

• Add male or female headers around the perimeter to make the module easily pluggable.
• Apply a conformal coating or protective clear spray on soldered pads for long-term corrosion prevention in humid BD weather.
• Mount standoff spacers in the corner holes to stack multiple boards vertically inside custom enclosures.

Benefits

• Provides a clean, professional, and long-lasting alternative to fragile breadboard wiring.
• Reduces debugging time by establishing stable, solder-permanence electronic connections.
• Offers exceptional value for prototyping custom robotics and automated electronic hardware.
