PCB Fabrication Tolerances

Our PCB fabrication tolerances ensure your boards are built to spec, reliable in performance, and production-ready from day one.

Imagineering delivers the tight tolerances that make the difference between a first-pass success and costly delays. Whether it’s prototypes or full-scale production, we hold every board to the highest standards of precision.

Why Tolerances Matter

Getting It Right the First Time

When it comes to PCBs, precision is the foundation of performance. Every trace width, drill hole, and copper-to-edge clearance falls under the banner of tolerance in manufacturing. Even the smallest deviation can cause delays, assembly headaches, or outright failure.

Here’s what tight tolerances mean for your project:

Reliability

Boards that meet spec and function as intended, without costly rework.

Faster Assembly

Proper hole alignment and registration mean smoother downstream builds.

Design Confidence

Push density and complexity, knowing your boards can be manufactured.

At Imagineering, our tolerance standards are engineered to eliminate surprises so your designs work right, the first time.

Fabrication Tolerance Capabilities

Built Per Your Specs

Our boards are manufactured to exacting standards so your designs scale smoothly from prototype to production. Here’s what you can expect:

Core Fabrication Tolerances

  • Hole Size: ±0.004″ standard (tighter available on request)
  • Annular Ring: Down to 0.005″ for plated through-holes
  • Trace & Space: 0.003″ / 0.003″ at 0.5 oz; 0.004″ / 0.004″ at 1 oz
  • Copper-to-Edge Clearance: 0.007″ outer layer; 0.010″ inner layer
  • Board Thickness: ±10% across multilayer builds
  • Routing / Outline: ±0.005″

Advanced Capabilities

  • Via-in-pad plated over (VIPPO)
  • Laser-drilled microvias down to 4 mil
  • Controlled impedance builds with ±5% tolerance
  • High-layer counts and mixed-material stackups
Every number here is a commitment, not just a guideline. By holding these tolerances, we help ensure your boards assemble cleanly, perform reliably, and stand up to the most demanding applications.

Precision Backed by Process

Quality & Certifications You Can Trust

When you partner with Imagineering, you’re getting more than specs on a page. We show our commitment through actions, not words. Our proof is certified adherence to internationally recognized standards and decades of consistent delivery.

Advanced Capabilities

  • Automated Optical Inspection (AOI) for fine features
  • Electrical testing for continuity and shorts
  • Layer-to-layer registration verification
  • Final dimensional checks on every order

Certifications Built Into Every Board:

  • AS9100D / ISO 9001:2015 – aerospace-grade quality systems
  • ITAR registered – defense compliance ready
  • UL & RoHS certified – environmental and safety assurance
Tight tolerances don’t happen by accident. They’re the result of disciplined processes and rigorous checks at every stage. At Imagineering, quality is engineered into each build.
