In-Line Test Systems, XILS and MILS | Productronica 2025 – Product Highlight

XILS and MILS Smart In-Line PCB Testing

The Challenge

Reliability & Precision vs. Time & Space Efficiency

In today’s electronics industry, the real challenge lies in finding the balance between ensuring maximum reliability and accuracy in testing processes and, at the same time, optimizing time and space resources within the production plant. PCBs are becoming increasingly complex, with higher component density, advanced connectivity, and strict quality requirements. On top of this comes the need to adapt to shorter product life cycles and highly variable production volumes.

In this scenario, engineers need testing solutions that ensure robust, repeatable, and traceable tests, without compromising productivity or space efficiency.

The Technology

Mechanical Precision and Smart Control

The advanced inline handlers have been designed as a cost-effective, compact, and easy-to-integrate solution for any production environment, standing out especially in ICT (In-Circuit Test), ISP (In-System Programming), and FCT (Functional Test) applications.

Their architecture is based on a dual SMEMA-level transport system, which allows multiple units to be connected in series and eliminates the need for parallel lines, maximizing space efficiency on the shop floor. Thanks to this configuration, the equipment provides a continuous and synchronized flow of PCBs, ensuring a bottleneck-free testing process.

Another key differentiator is its software-based configuration, which allows the line to be quickly adapted to different products and test requirements without the need for complex physical modifications. In addition, the side actuation for USB and Ethernet connectors ensures precise and controlled insertion, reducing wear and increasing the reliability of results.

Furthermore, these handlers have been designed to provide maximum flexibility in the integration of test technologies, supporting instrumentation and solutions from leading industry manufacturers such as Teradyne, Keysight, Checksum, TRI, Goepel electronic, National Instruments, or SMH (Flash Runner), as well as advanced methodologies such as Digital ICT, boundary scan, LED testing, or ASA (Analog Signature Analysis).

The result is a technology that combines mechanical precision, smart control, and universal compatibility, delivering to manufacturers a robust and scalable platform that evolves in step with the needs of the electronics industry.

The Benefits in Practice

Building on this innovative design, the in-line handlers deliver tangible practical benefits such as:

Higher Throughput

Continuous PCB processing, and steady flow.

Reduced Footprint

Dual conveyor, maximum capacity in minimal space.

Total Flexibility

Software-configurable for different types of tests.

Reduced Downtime

Industry Applications

The incorporation of advanced inline handlers represents a clear competitive advantage for any electronic production plant. Firstly, they allow for significantly reduced cycle times, resulting in higher productivity without compromising test quality. Additionally, their compact and modular design offers the possibility to optimize available factory space, which is especially relevant in environments where every square meter counts.

Moreover, compatibility with standard industry instrumentation and the ability to combine different testing technologies on a single line facilitate the integration of complex processes in a simple and scalable way. This not only ensures more efficient production but also provides the flexibility needed to adapt to new products and requirements without the need for significant additional investments.

Finally, ergonomics in fixture replacement and integrated communication between handlers reduce operational costs and simplify the daily tasks of engineering teams. In this way, companies not only improve the reliability and traceability of their tests but also achieve a thanks to the perfect balance between performance, precision, and efficiency.
