Optimized Manufacturing Capabilities

We focus on the industry-standard specifications that 90% of modern electronics require. By specializing in high-reliability SMT assembly without the overhead of ultra-miniature BGA setups, we pass significant speed and cost savings directly to you.

01. SMT Assembly

Our assembly line is tuned for rapid-turn, high-yield production of standard SMT designs.

Min Component Size0402 (Standard)
Max Board Size250 mm x 350 mm
Component TypesPassive, SOIC, QFP, SOT, DFN
Lead-Free SolderStandard SAC305

The 0402 Sweet Spot

While others chase sub-miniature parts that require specialized inspection, we specialize in 0402 and larger. This ensures consistent solder joints and allows us to utilize high-definition Automated Optical Inspection (AOI) for 100% of our assembly runs without the cost of X-ray overhead.

02. PCB Fabrication

Industry-standard fabrication specs that match your design rules in Altium, KiCad, or Eagle.

Trace & Space

6 / 6 mil

Minimum width and clearance

Minimum Drill

0.3 mm

Mechanical CNC Drilling

Layer Count

1 - 6 Layers

Standard FR-4 (TG130-140)

Quality Control & Inspection

Because we specialize in standard SMT footprints (0402 and larger), our quality process is optimized for high-definition optical verification. Every board that leaves Express Fab USA undergoes a multi-stage inspection process:

1

Automated Optical Inspection (AOI)

Our high-resolution AOI systems scan every placement for correct orientation, polarity, and solder fillet integrity. This catches 99.9% of common assembly errors instantly.

2

High-Magnification Visual Review

Technicians perform manual audits under digital microscopes to ensure cosmetic perfection and mechanical stability of through-hole components.

3

Electrical Continuity Testing

For fabrication, we utilize flying probe or bed-of-nails testing to guarantee that every trace on your PCB is electrically sound before assembly begins.

Our AOI systems provide 100% coverage for SMT placements.

Our "Build-to-Data" Philosophy

To maintain our high-velocity, cost-effective domestic model, Express Fab USA operates on a Direct-Data / No-Touch philosophy. Our systems are fully automated and designed to execute your precise instructions without manual interpretation.

  • Data Over Inference: We build exactly as prescribed by your XY (Pick-and-Place) files and Gerbers. We do not "infer" intent from silkscreen markings or second-guess component rotations.
  • No Text Instructions: Our process is 100% digital. We do not accept or process separate text files or manual assembly notes.
  • XY Priority: Placement and rotation is determined solely by your coordinate data. If the XY file specifies a rotation, that is how the component will be placed.
  • Design Ownership: We believe 100% of design intent can be expressed via standard output files (gerber, cnc, xy etc.). This "No-Touch" approach ensures the board you receive is a perfect mirror of the data you provided.

The Express Fab Quality Guarantee

We guarantee that your boards will be manufactured and assembled in 100% accordance with your provided design data. Every solder joint, component placement, and trace path is verified through our multi-stage AOI and visual inspection process.

Build-to-Data Accountability

If we deviate from your provided Gerber or XY instructions, we will make it right—guaranteed.
