Multitest Launches Atlas Contactor: Cost-Efficient High Performance Solution for Large I/O Count Devices in High End Digital Applications

Multitest recently launched the Atlas contactor, which has been optimized for cost-efficient and reliable testing of high end digital high ball count BGAs. Based on the well-established Multitest QuadTech flat probe technology, the Atlas contactor combines advanced mechanical and electrical probe technology for improved functionality and performance in manual test and automated test.

With an optimal insertion force and a large compliance window, the Atlas provides ultra-stable contact resistance over hundreds of thousands of device insertions. The Atlas can be configured for use without a floating alignment plate. The low Atlas per pin insertion force significantly reduces insertion strain on automated test handling systems while making the Atlas easier to use in manual test.

Atlas’ mechanical integrity includes the controlled insertion forces that are determined by the compression of a precision alloy stainless steel spring. Properties of the spring are engineered to offer predictable long-term performance over a broad temperature range: -50° to +150° C along with a typical life of 500K insertions. Atlas 040 insertion forces are controlled to just 25 grams per pin.

The insertion loss of Atlas 040 is measured at 18.5 GHz @-1dB while the return loss is measures at 14.72 GHz @ -20dB. The Atlas’ bandwidth supports the spectral content of most high speed digital device for ensuring great signal fidelity for maintaining digital edge rates. With a test height of only 3.53 mm, the Atlas 040 has the bandwidth for obtaining superb signal fidelity.

The Atlas design combines fine pitch capability with reduced contact height, force, and no damage zone contacting to meet the contacting needs of next generation for advanced high-end digital devices with typically 600 to 5,000 ball count range.

Bert Brost, Product Managers, explains: “Currently the Atlas contactor supports pitches down to 0.4 mm. Soon we will launch the Atlas for 0.3 mm pitches continuing the miniaturization and advancement of our field proven QuadTech flat probe technology

Expanding Application Range to Challenging SOT23 Packages

Multitests Tri-Temp Gravity Handler MT9928 supports SOT23 Devices

Multitest recently shipped a high volume test handling solution for SOT23 packages. The innovative conversion kit design allows for tri-temp testing of SOT23 packages on the production proven MT9928 gravity handler.

Traditionally, these packages were handled on turret handlers, but these types of handlers do not support temperature testing. With a growing number of SOT23 application, which require testing at various temperatures, this is no longer sufficient.

The new Multitest kit design applies an innovative guiding principle, which is able to handle packages with missing upper body mold e.g. the SOT23 package with 4, 5 or 6 leads.

With more than 1100 installations the MT9928 is well-established and provides field proven reliability and performances. Its modular and scalable design and the variety of options allow configuration of the MT9928 exactly according to the test needs. The MT9928 offers a large soak capacity and supports the entire ambient-hot-cold temperature range at outstanding accuracy and stability.

ECT Accordion™ Technology Used for Innovative High Current Connector Solution

Innovative interconnect design exceeds the limitations of standard spring probes

Everett Charles Technologies (ECT) has developed a customized high current connector for testing electrical power components based on an unprecedented design using ECT’s Accordion™ compliant contacts. In addition to the demanding high power performance this challenging application called for a cutting-edge connector design to comply with the extremely small space limitations and contact surfaces.

The challenge of this project was to transfer continuous current exceeding 50 Amps through small contact surface area, not well suited for standard spring probes. ECT developed a technical solution that gives the customer high cycle life and compressed foot print based on the Accordion™ compliant contact. Compared to standard spring probe solutions, the Accordion™ based design supports higher current and leverages more reliable surface contact.

The Accordion™ compliant contact is a proven solution for high density / high current applications. Accordion™ contacts can be integrated into a connector to provide multiple, independent current paths. The Accordion™ ensures low resistance and reduces power loss and therefore heat loss. Accordion™ contacts placed in parallel overcome contact challenges including irregular surface topography, dirt and debris, and non-parallel connection. In addition, the probe is modular. This allows varying the current capacity as required for each test point, but uses a consistent reliable design.

Tony DeRosa, Product Manager, explains: “For this customer project we designed a compliant connector with a direct current path using multiple independent current paths. We developed this innovative solution leveraging the unique advantages of our Accordion™ contact: flat , single piece compliant spring design for best reliability in high current applications. This customer specific solution packed several Accordion™ contacts together, ensuring side to side contact and specific overlapping, redundant contact points through-out the assembly. No comparable solution had been available to the customer before. It proves once more, how the team at Everett Charles Technologies combines leading-edge technology with innovation and experience to create the best solutions for our customers.”
