Building a Future of Continuous Improvement

As a contract manufacturer in the automotive sector, SIIX EMS Mexico (SEM) faces tough demands for productivity, quality, and compliance. Customers expect not only high volume but full traceability and validation.

Since 2015, Cogiscan has helped SEM with their explosive growth. When they first adopted the Cogiscan platform, they only had about six SMT lines. Today, with 30 lines, the Cogiscan system is used on every line, creating a unified backbone for traceability and process control.

Growth has never meant shortcuts. Each new line brought requirements for automation, integration, and real-time data. Cogiscan's modular platform and Open Interface helped SEM to scale seamlessly as they’ve built custom tools to automate workflows and maintain visibility across the entire operation.

Result: A growing production environment confident in the quality and compliance of its output.

Scaling Traceability with Every Step Forward

In the automotive industry, traceability is not just a best practice, it is an essential requirement. For SIIX EMS Mexico, this means complying with rigorous standards, including those set by the IATF 16949 certification (formerly TS 16949), which governs quality and component traceability.

Every part and every element produced on the manufacturing lines must be identified, recorded, and tracked with precision. There is no margin for error, ensuring that the complete history, from raw material to finished product, is available at any time. Detailed reports not only allow SEM to meet customer audit requirements but also enable a rapid response in the event of a recall or non-conformance.
Customers want to know that the contract manufacturer can provide traceability reports, even if they don't always ask for them. If ever there's a complaint or issue, we need to show we have traceability on the materials used.

Quality and Reliability: Catching Issues Early

Tight quality control is paramount in electronics manufacturing, especially in automotive electronics, where a single mistake can have serious consequences. In this sense, Cogiscan’s technology has been key SEM’s early detection and prevention.

The SIIX EMS Mexico team has built multiple different custom applications with Cogiscan’s Open Interface in order to improve their validation processes across all SMT lines. In case of skipped steps, or components that fail to meet the specifications, or incorrect process parameters, their team is alerted of the detected issue, and the production line can be stopped.  

Precision in electronics manufacturing is essential, and SEM relies on Product Flow Controller (PFCs) to maintain that standard. These networked devices automatically stop the machine whenever a setup or process falls outside specifications, ensuring defective products never reach downstream operations. In addition, SIIX EMS Mexico uses PFCs in post-SMT stages such as conformal coating to maintain quality and collect data that supports complete traceability.

Seamless integration was also key as SEM added new machines. Cogiscan supported their team in capturing and integrating all necessary data from new equipment all while maintaining traceability without sacrificing quality.

Cogiscan's platform supports real-time feedback and validation to enable operators and managers to act swiftly and maintain responsibility. The result is that SEM has maintained and even elevated the quality of its standards, while it grows without compromising critical validation steps.
Cogiscan has been a reliable partner for us, providing quality solutions that meet our needs since 2015. One of the key benefits of their system is the straightforward way we can easily access and push/pull data – this capability enables us, as a contract manufacturer, to develop internal solutions that integrate with and receive automatic validation feedback.

As we’ve grown and added new SMT lines to our factory, we continue to implement Cogiscan’s technology to also ensure traceability for our automotive customers. Their traceability helps us maintain accurate records of the materials and processes used in our products to demonstrate compliance when needed. With Cogiscan, we have the confidence and tools to meet the highest standards of traceability, quality, and reliability
