Our Spain PCBA Quality Control Process
Below is a quality control process of our Spain PCB assembly:
- Raw Material Inspection: Upon the arrival of all components and PCBs, we implement a two-step rigorous inspection process to eliminate quality risks from the source. First, we verify the supplier’s qualification certificates and batch information to ensure materials come from authorized EU suppliers, then conduct professional tests including appearance checks, electrical performance detection, and counterfeit identification. This strict process ensures all materials fully comply with EU RoHS 2.0 and REACH standards, with a raw material inspection pass rate of 99.9% and a 100% interception rate for counterfeit or defective components.
- In-Process Quality Control: Our professional team conducts full-process monitoring of every key step in SMT and DIP assembly, including solder paste printing, component mounting, and reflow soldering. We implement real-time patrol inspections every hour, and our MES system records detailed data of each operation from component placement coordinates to soldering temperature curves for full traceability. Once any abnormal issue is found, we suspend the corresponding production link immediately, with an abnormal response time within 1 hour, ensuring potential quality problems are resolved before proceeding to the next process.
- Advanced Testing Equipment: We are equipped with high-precision AOI, SPI, and FCT testing equipment to build a three-dimensional quality inspection barrier. SPI is used to detect solder paste printing quality, controlling solder paste thickness deviation within ±10μm to avoid short circuits or poor soldering caused by uneven solder paste. AOI automatically scans PCBs from multiple angles to detect soldering defects, component misalignment, and missing parts with 99.8% accuracy. FCT conducts full functional testing on finished assemblies to verify whether their electrical performance meets design requirements, covering 100% of functional indicators.
- 5-Year Warranty Commitment: Our industry-leading 5-year warranty is a concrete reflection of our confidence in product quality, covering all quality issues caused by raw material defects, assembly errors, and performance failures during normal use.
