Product Description

The 3 x 4 Inch General Purpose Zero PCB, commonly known as a DOT PCB or perfboard, is a versatile and essential tool for creating permanent electronic circuits. Featuring a rigid sheet of high-quality FR2 material, this board is pre-drilled with a precision grid of holes at standard intervals. Each hole is encircled by a dedicated copper pad on the bottom side, allowing you to insert and solder component leads without risking accidental short circuits with adjacent pads. Ideal for medium-sized projects, this board provides a reliable and vibration-resistant foundation for transitioning your breadboard designs into finished professional prototypes.

Detailed Key Features

Universal 2.54mm Grid: Designed with the industry-standard 0.1-inch hole spacing, making it perfectly compatible with standard ICs, DIP sockets, and pin headers.
Stable Brown FR2 Base: The high-quality phenolic resin base offers excellent electrical insulation and mechanical rigidity for long-term project stability.
Precision-Etched Copper Pads: Features high-conductivity copper pads that are easy to solder, ensuring robust mechanical bonds and clean electrical signal paths.
Optimised Board Thickness: With a thickness range of 1.0mm to 1.6mm, the board provides the perfect balance between being lightweight and offering superior durability.
Flexible Point-to-Point Wiring: The "Zero" connectivity layout gives you complete creative freedom to bridge pads using component leads or conducting jumper wires.

All Technical Details

Colour Profile: Features a professional brown finish, characteristic of high-quality FR2 phenolic boards.
Layer Configuration: Single-sided design with copper pads on the bottom layer to simplify wiring and keep the top side organised.
Thermal Performance: Resistant to standard soldering temperatures, preventing pad lifting or board warping during assembly.
Hole Precision: Consistent 0.3mm minimum hole size allows for easy insertion of most standard through-hole component leads.
Surface Area: The 3x4 inch footprint provides a generous 12 square inches of working space for complex analogue or digital circuits.

Prototyping & Engineering Tips (Robogears Exclusive)

Efficient Trace Creation: To connect components on this board, bend the excess leads of resistors or capacitors across the adjacent pads you wish to join. This creates a solid copper "trace" that is much more reliable than using just solder.
Component Orientation: Always insert your components from the plain (non-copper) side. This protects the sensitive copper pads from physical damage and makes your final project look much cleaner and professional.
Mechanical Mounting: Use the edges of the board to drill small mounting holes for M3 standoffs if your project needs to be secured inside an enclosure or at your Pimpri workshop station.
Flux for Cleanliness: If the copper pads appear slightly dull, apply a tiny amount of soldering flux or rub the board with a pencil eraser before you start. This will ensure your solder flows instantly for a shiny, "cold-joint" free finish.
