SPACER 30MM - CUPPER PARTS FOR PCB AND ELECTRONICS

The Copper Spacer 30mm is a cylindrical standoff designed for spacing, mounting, and stacking printed circuit boards (PCBs) within electronic enclosures. Manufactured from high-purity copper, this component provides both mechanical rigidity and excellent electrical conductivity. The 30mm length creates a defined gap between two boards or between a board and a chassis panel, allowing clearance for components, airflow, and wiring. While thread specification is not explicitly stated, these spacers commonly feature M3 internal threads (metric) or may be unthreaded through-hole type – compatible with standard M3 screws for secure fastening. Copper material offers low electrical resistance, making this spacer ideal for grounding applications where electrical continuity between stacked PCBs or to a metal chassis is required. Copper also provides natural corrosion resistance and good solderability. Suitable for professional PCB assemblies, prototyping, and DIY electronics requiring precise mechanical support with electrical functionality.

Applications

Stacking multiple PCBs – Create 30mm vertical separation between boards in multilayer assemblies

Chassis mounting – Mount PCBs away from metal enclosures to prevent short circuits

Grounding and shielding – Provide low-resistance electrical path between boards or to chassis ground

Power electronics – Copper handles higher currents for grounding straps

Audio and RF circuits – Reduce ground loops with solid copper paths

3D printers and CNC controllers – Secure controller boards with proper clearance

Prototyping and test fixtures – Build stable mechanical structures for development
