FR4 CNC Machining Applications & Parts

At Sunnyhowe, we precision-machine FR4 (G10) into high-performance components for industries that demand excellent electrical insulation, mechanical strength, and flame retardancy. Here are common parts we manufacture:

1. Electrical Insulation Components

• PCB Test Fixtures: Insulating bases, probe plates, and mounting boards for In-Circuit Test (ICT) and flying probe testers.

• Terminal Boards & Blocks: Machined blocks and strips with drilled and tapped holes for secure electrical connections.

• Bus Supports & Insulators: Standoffs, spacers, and barriers for transformers, switchgear, and power supplies.

• Circuit Breaker Parts: Arc chutes, barriers, and isolation plates that meet UL94 V-0 standards.

2. Precision Mechanical & Wear Parts

• Wear Rails & Guides: Low-friction guide rails, ways, and liners for CNC machinery and automation equipment, offering a non-metallic alternative.

• Bushings & Bearings: Self-lubricating bushings, washers, and thrust bearings for applications requiring corrosion resistance and electrical isolation.

• Gaskets & Shims: Complex gaskets and precision shims for high-temperature and corrosive environments.

3. Jigs, Fixtures, & Factory Automation

• Assembly Jigs: Lightweight, rigid, and non-conductive jigs and fixtures for electronic assembly and welding.

• Sensor Mounts: Custom brackets and enclosures for proximity sensors and other sensitive electronics.

• Tooling Plates: Flat, stable plates for mounting components in measurement and optical systems.
