Key Features of 7x9 CM Single Side Copper Dotted PCB Board
- Standard 2.54 mm Pitch: Perfectly spaced holes accept all standard DIP ICs, headers, resistors, capacitors, transistors, and other through-hole components without modification.
- Individually Isolated Copper Pads: Each hole has its own separate copper pad, giving you complete freedom to design custom trace routes using solder bridges or jumper wires.
- FR-4 Grade Fiberglass Construction: Industry-standard laminate provides superior mechanical rigidity, excellent thermal endurance during soldering, and reliable electrical insulation.
- Generous 7x9 cm Working Area: Approximately 884 usable holes offer enough real estate for moderately complex circuits including microcontroller breakouts, amplifier stages, and sensor interfaces.
- Single-Sided Design: Component placement on the non-copper side with soldering on the copper side simplifies assembly and makes visual inspection and debugging straightforward.
- Easy to Cut and Shape: The FR-4 board can be scored and snapped or cut with a hacksaw to create smaller custom-sized boards for tight enclosures.
- Lead-Free & RoHS Compliant: Manufactured to meet environmental safety standards, suitable for educational institutions and professional environments alike.
- Lightweight and Compact: At just ~18 grams, the board adds minimal weight to portable or wearable project builds.
Product Description
The 7x9 CM Single Side Copper Dotted PCB Board is a universal prototyping platform that bridges the gap between breadboard experimentation and professional custom PCB manufacturing. Unlike breadboards where connections can be loose and unreliable, soldered perfboard circuits offer permanent, vibration-resistant connections that are suitable for real-world deployment.
How It Works
The board consists of a rigid FR-4 fiberglass substrate with a matrix of holes drilled at a standard 2.54 mm (100 mil) pitch. On one side, each hole is surrounded by an individual circular copper pad. You insert component leads from the non-copper side, flip the board, and solder each lead to its corresponding copper pad. Circuit connections between pads are made by running solder bridges between adjacent pads or by using short lengths of wire on the copper side.
Build Quality & Material
FR-4 is the global standard for PCB substrate material. It is a composite of woven fiberglass cloth and epoxy resin that delivers a unique combination of properties: high mechanical strength (flexural strength ~415 MPa), excellent electrical
