PCB CNC Machining Service

FR4 is the most popular material for PCBs. This material is made of woven glass cloth with epoxy resin.

• Key Features:
  • Thickness: 0.2–6.0 mm
  • Doesn’t catch fire easily (UL94-V0 rated)
  • Works in temperatures up to 130–180°C
  • Great for keeping electricity where it should be

When to use it: FR4 works great for PCB drilling pads, making FPC stronger, and keeping transformers safe. It’s the go-to choice for most circuit boards because it’s strong and doesn’t cost too much.

This lightweight metal is perfect for PCBs that need to stay cool.

• Key Features:
  • Moves heat very well (167 W/m·K)
  • Strong (310 MPa)
  • Weighs 2.7 g/cm³
  • Doesn’t rust easily

When to use it: Choose aluminum for heat sinks, RF shields, and CNC enclosures. Our 5-axis machining service can shape aluminum with tiny details down to ±0.1mm.

When you need something extremely strong but light, carbon fiber is perfect.

• Key Features:
  • Super strong (3,500 MPa)
  • Doesn’t change size much when hot
  • Very light (1.6 g/cm³)
  • Stops vibrations

When to use it: Great for drone frames, tools that need to be strong, and parts that get a lot of wear. Carbon fiber also blocks EMI (electromagnetic interference).

Need something that can bend? Polyimide is the answer.

• Key Features:
  • Can handle high heat (up to 260°C)
  • Keeps electricity where it should be (200–300 V/mil)
  • Very thin (12.5–125 µm)
  • Can bend without breaking

When to use it: Perfect for flexible PCBs, sensors that work in hot places, and wiring in airplanes. It can be bent many times without breaking.

For high-frequency circuits, Rogers materials are the best choice.

• Key Features:
  • Special electrical properties (dielectric constant: 3.3–6.15)
  • Very little signal loss (0.0027)
  • Stays stable when hot
  • Made for fast signals

When to use it: Choose Rogers for 5G antennas, microwave circuits, and car radars. Our CNC milling experts can work with these special materials to get the best results.

For PCBs that need to carry lots of power, copper-clad laminates are perfect.

• Key Features:
  • Copper thickness options from 0.5–6 oz
  • Sticks well to the base (1.0–1.4 N/mm peel strength)
  • Can handle heat (Tg 150–170°C)
  • Great for moving electricity

When to use it: Best for power electronics, high-current PCBs, and LED drivers. These materials help make energy-efficient systems for factories and cars.
