New solution offers replacement for legacy test systems

Seica SpA has introduced the new VALID LR system, created to deliver a solution for customers looking to replace legacy test systems that are no longer supported by the original manufacturers. The new system's native multi-resource architecture gives it the flexibility and performance needed to seamlessly migrate existing test programs and fixtures while preserving original fault coverage and providing a smooth transition for users.

The company has unparalleled experience in providing legacy replacement solutions, with consolidated success in replacing numerous brands of legacy test systems, allowing customers to maintain long-term logistics support at competitive costs. The hardware and software of the company's VIP platform combine the capability to support older technologies with high-performance, state-of-the-art tools, which are then also available for the development of new test programs and the legacy replacement of existing applications.

The Valid LR can carry out the replacement of obsolete systems at three levels:

• Mechanical via an adapter enabling the reuse of the original fixtures.
• Electrical, via digital multiplexing hardware, can maintain the same distribution of digital I/Os present in the legacy system.
• Software, via automatic tools, enables the migration of existing test programs to Seica's state-of-the-art VIVA platform.

The system supports a full range of test performances, including in-circuit tests, functional tests, dynamic digital tests, and boundary-scan tests. It can also be configured with a range of additional resources, such as LED tests, On-Board Programming (OBP) capability, and third-party instrumentation.

The system is engineered for high scalability and performance. It has an innovative, cableless architecture and supports up to 5888 channels with a 1:8 digital multiplexer. It provides up to 24 programmable power supplies, ensuring flexible management of power-on tests. The intuitive, customisable operator interface is constructed on a PLC system with OPC-UA communication for seamless integration into modern test environments.

The system also includes up to 64 general-purpose I/O channels per Unit Under Test (UUT) and offers four independent vacuum paths and two compressed air paths for efficient fixture operation. It is equipped with 16 OBP channels, compatible with Seica's DeviceClip and third-party technologies. The front panel provides extensive connectivity options, including USB 3.0 ports, Ethernet, digital sync interfaces for debugging, and compressed air connections, ensuring a versatile and future-proof test solution.

With VALID LR, the company continues to lead in Legacy Replacement technology, delivering innovative solutions that help customers maintain efficiency, minimise downtime, optimise existing investments and future-proof their testing operations.
