When it comes to Printed Circuit Board Assembly (PCBA), quality is not something you inspect at the end — it’s something you build into every step of the process. At Fumax, we know that every assembled board could be the heart of someone’s next breakthrough product. That’s why before a single PCBA leaves our factory, it goes through 19 rigorous checks designed to catch issues early, prevent costly rework, and ensure long-term reliability.
Our approach combines engineering know-how, quality control discipline, and practical manufacturing experience to minimize risks and give our clients complete confidence.
Before production starts, our engineers thoroughly review Gerber files to ensure all layers, drill files, and design details are correct and consistent.
We cross-check every component in the BOM against the PCB layout to avoid mismatches in footprint, value, or orientation.
Our team identifies potential design issues that could cause production delays or defects, such as insufficient pad sizes, via-in-pad without filling, or tight trace-to-trace clearances.
All components are sourced from authorized distributors or verified suppliers to avoid counterfeit or substandard parts.
Components and bare PCBs undergo visual and dimensional inspections to verify quality before entering the production floor.
We strictly follow MSD (Moisture Sensitive Device) protocols, including dry packing, baking, and controlled storage.
We ensure the SMT stencil matches the Gerber paste layer exactly and that aperture dimensions are within tolerance for consistent solder paste deposition.
Automated inspection of solder paste height, volume, and alignment ensures stable solder joints from the start.
The first assembled board is inspected against all design files to verify accuracy before mass production proceeds.
Every board goes through AOI to detect missing components, incorrect polarity, solder bridges, and tombstoning.
For BGA and other hidden-solder components, X-ray inspection ensures correct ball alignment, wetting, and void levels.
Where applicable, we perform ICT to verify electrical connections, component placement, and circuit integrity.
We run customer-provided or Fumax-developed test programs to confirm the board performs exactly as intended.
From handling to packaging, all processes are conducted in ESD-safe environments to prevent electrostatic damage.
Trained quality inspectors perform final manual checks for cosmetic and assembly issues.
We confirm PCB dimensions and connector alignments to ensure mechanical fit in final enclosures.
If required, boards are cleaned to IPC standards to remove flux residues that could cause corrosion or conductivity issues.
For high-reliability applications, we run extended burn-in cycles to detect early-life failures.
Before shipment, packaging is inspected for protection against moisture, vibration, and handling damage during transit.
Skipping or rushing any of these steps can lead to field failures, product recalls, and brand damage. At Fumax, we believe in front-loading quality — catching issues before they leave the factory, not after they reach your customers.
These 19 checks are not just procedures; they’re part of our manufacturing culture. We apply them equally to small prototype batches and high-volume runs, ensuring consistent reliability for startups and established brands alike.
Your product deserves the same attention to detail whether you’re ordering 10 boards or 10,000. With Fumax, you can count on precision, reliability, and a partner who takes your deadlines and reputation seriously.
