Double-Sided PCB Blank (150x200mm)

A blank PCB board for making your own custom circuit boards in your very own workshop, lab or classroom. It provides a reliable medium for engineers and makers to translate digital PCB designs into physical prototypes using desktop milling, chemical etching or laser ablating.

When you want to prototype a circuit without waiting for an external fab house (usually overseas), or when a breadboard or protoboard is too temporary or messy for the job. Makers, students and engineers can use it to produce simple custom PCBs for testing layouts, breakout boards, control circuits and educational electronics projects.

Since a CNC is being used to make the PCB, design the whole product to be made on the one machine! Add an enclosure with the same tooling.

The FR-4 substrate provides a rigid, standard PCB-style base for practical prototypes, while the double-sided copper format keeps fabrication flexible (but requires aligning and flipping the board). This is raw PCB material, so it will need suitable design files, tooling and fabrication equipment before components can be soldered to it.

Key Features

• Make PCBs in-house: Make a custom PCB without sending every revision to a fabrication service, saving weeks during prototyping.
• Cleaner than hand-wired prototyping: A milled PCB can give your project defined traces and a more repeatable layout than point-to-point wiring on perfboard or protoboard.
• Flexible fabrication for basic circuits: The double-sided copper lets you add a ground plane or route hard-to-reach pads, use a THT lead as a replacement for a via, or use PCB rivets to connect planes
• Rigid PCB-style substrate: FR-4 fibreglass provides a durable base material commonly used for rigid printed circuit boards.
• Suitable for CNC PCB fabrication: Designed for users making boards with appropriate milling, drilling and profiling tools. Solder mask and silkscreen are not included on the blank board and require additional process steps if needed; we stock the PCB Fabrication Kit for just that!
• And other fabrication methods: chemical etching, a fibre laser, or other methods to create the conductive islands required to make a functioning PCB

Specifications

• 1.5mm thick
• 150mm x 200mm
• Double-Sided Copper (Bare FR-4 on the other side)
• FR-4 Fiberglass substrate

Using a CNC, we have had success with a minimum track width of around 0.25 mm and a track clearance of 0.2mm (depending on the milling bit used).
