Our Remanufacturing Process

Quality Electronic and Mechatronic Products backed by The Weller Way

Meticulous Disassembly

At the heart of our sustainability and precision engineering practices, every Electronics and Mechatronics core undergoes a meticulous disassembly process by our skilled technicians. Each reusable component is carefully inspected to ensure optimal performance and reliability.

  • Soft parts and consumables are responsibly discarded to maintain quality standards.
  • Hardware and castings are thoroughly cleaned and professionally reconditioned.
  • Printed circuit boards (PCBs) are stripped, washed, and prepared for reuse.
  • All recovered parts undergo a final inspection before being sent to assembly, ensuring they meet our rigorous standards.

This process not only supports environmental responsibility but also guarantees high-performance results for every rebuilt unit.

Precision Remanufacturing

Our purpose-built Electronics and Mechatronics lab is designed to deliver precision and quality at every stage of the remanufacturing process. Featuring climate control and industry-standard electrostatic discharge (ESD) mitigation systems, the lab ensures a safe and stable environment for sensitive components.

  • Every product is remanufactured using a mandatory replacement list of up to 65 board-level components, including EEPROMs, processors, drivers, and RAM.
  • All circuit board rework is performed by IPC 7711/7721-certified technicians, ensuring compliance with global standards for electronics repair and modification.

This rigorous process guarantees consistent performance, reliability, and long-term durability—making our remanufactured units a trusted choice for high-demand applications.

Rigorous Testing

Every Weller remanufactured electronic and mechatronic part undergoes multiple rounds of testing to ensure exceptional quality and reliability. Our proprietary test systems simulate real-world dynamic operation, allowing us to validate performance under demanding conditions.

  • Each component is tested at least twice—once at ambient temperature and once at elevated temperatures that mirror actual operating environments.
  • For products with known vulnerabilities, such as failures in sub-zero conditions or under vibration, we conduct environmental testing from -20°C to +230°C and up to 500 G-force to ensure durability and resilience.
  • All testing is performed using custom-built equipment designed in-house to meet the highest industry standards.

This comprehensive validation process ensures that every remanufactured part delivers consistent performance, even in the most extreme conditions.
