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.
Our assembly line is tuned for rapid-turn, high-yield production of standard SMT designs.
| Min Component Size | 0402 (Standard) |
|---|---|
| Max Board Size | 250 mm x 300 mm |
| Component Types | Passive, SOIC, QFP, SOT, DFN |
| Lead-Free Solder | Standard SAC305 |
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.
Industry-standard fabrication specs that match your design rules in Altium, KiCad, or Eagle.

Standard FR-4 (TG130-140)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:
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.
Technicians perform manual audits under digital microscopes to ensure cosmetic perfection and mechanical stability of through-hole components.
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.
