Professional CNC milling of green FR4 precision parts

Product Overview

We offer professional-grade FR4 epoxy resin board CNC precision processing services, specially designed for the high reliability requirements of the electronics, electrical and special industrial fields. By adopting high-precision multi-axis milling technology, we ensure that every FR4 part features strict dimensional accuracy, excellent electrical performance and stable mechanical properties.

Professional FR4 material processing solutions

We strictly select high-quality FR4 substrates that comply with the IPC-4101 standard and possess the following professional processing capabilities:

Precision multi-layer board processing: Capable of handling PCB structures ranging from 1 to 20 layers, maintaining the integrity of interlayer bonding

Precise thickness control: The plate thickness processing range is 0.2-50mm, and the thickness tolerance can reach ±0.05mm

Complex structure forming: Achieve fine slot holes, irregular contours and high-precision step processing

Non-destructive cutting: Special diamond tools ensure that the glass fiber layer remains intact without chipping

Advantages of professional FR4 processing technology

Q:How fast can I receive a CNC prototype?

A:Lead times vary depending on part complexity, material availability, and finishing requirements, but generally:

• Simple prototypes: 1–3 business days

• Complex or multi-part projects: 5–10 business days

Expedited service is often available.

Q:What design files do I need to provide?

A：To get started, you should submit:

• 3D CAD files (preferably in STEP, IGES, or STL format)

• 2D drawings (PDF or DWG) if specific tolerances, threads, or surface finishes are required

Q:Can you handle tight tolerances?

A:Yes. CNC machining is ideal for achieving tight tolerances, typically within:

• ±0.005" (±0.127 mm) standard

• Tighter tolerances available upon request (e.g., ±0.001" or better)

Q:Is CNC prototyping suitable for functional testing?

A:Yes. CNC prototypes are made from real engineering-grade materials, making them ideal for functional testing, fit checks, and mechanical evaluations.

Q:Do you offer low-volume production in addition to prototypes?

A:Yes. Many CNC services provide bridge production or low-volume manufacturing, ideal for quantities from 1 to several hundred units.

Q:Is my design confidential?

A:Yes. Reputable CNC prototype services always sign Non-Disclosure Agreements (NDAs) and treat your files and intellectual property with full confidentiality.
