Expanding Capabilities for Temperature Testing

Multitest Soak Booster for Significant Reduction of Soaking Time

Multitest recently installed the well-established tri-temp handler MT9928 with an enhanced Soak Booster option. The Soak Booster cuts down the soak time by up to 50%. Multitest is currently the only company offering this kind of advanced technology for gravity handlers.

With this development Multitest is responding to the market need for temperature testing of large devices where soak time closely correlates with throughput,  and as a result, impacts the cost of test. High-volume production test of automotive devices is one market that benefits from this enhanced Soak Booster capability.

Whereas the industry standard for gravity handling is thermal heat transfer by radiation from track to device, Soak Booster uses convection as transfer principle. The temperature controlled air is blown directly to the device.

The “Soak Booster” option is built on Multitest’s excellence in temperature test solutions and is available for SO packages down to 300 mil in size.

Proven RF Performance Based on Proprietary Design

Link HB Contactor Compensates for HIB Tolerances

Multitest’s Link HB contactor exhibited excellent RF performance at customer sites ensuring ultra-clean high speed signals. The patent-pending design adds boardside compliance to compensate for board fabrication tolerances ensuring increased contact reliability and multisite stability.

Based on the well-established offset vertical architecture of the Link contactor, Multitest has developed the Link HB which adds boardside compliance with improved pin/pad concentrated contact. The proprietary design of the Link HB (patent pending) compensates for load board planarity tolerances, which are particularly critical in multisite applications.

The offset vertical architecture of the Link contactor family is designed to support superior test yield, maximum repeatability and low repair and replacement cost. The wipe motion of the probe provides scrub through oxides on the IC pads and cleans itself when moving back to its original free height.

This motion is fully decoupled from the connection to the test interface board resulting in a stable connection between the probe and the load board pad, avoiding pad wear and carbon debris buildup. This implementation also eliminates the potential for arcing between the probe and the test interface board pad.

Tony Tiengtum, Product Manager, commented, “Two recent European customers have confirmed the superior performance of the Link HB contactor.  In feedback to us they said the actual performance of the contactor was as advertised and went on to say that the Link contactor technology made it seem like the sockets were essentially transparent from an electrical perspective.”

Finding the ECT Equivalent to an Existing Spring Probe Solution

Everett Charles Technologies Introduces the new online part conversion tool

Everett Charles Technologies (ECT) has recently launched a new online parts conversion tool, which converts most industry or competitors’ part numbers to a functionally equivalent ECT solution.

ECT has implemented a new online tool to convert non-ECT spring probe part numbers into ECT equivalent part numbers. The new cross-reference tool provides customers with a quick and easy way of determining if an ECT equivalent probe is available for their application.

When a customer enters a competitor’s part number into the cross-reference tool, it will provide an exact match to an existing ECT part number if available or to a “functional” equivalent when a perfect match does not exist. The conversion result includes a link to the product page on the ECT website, where detailed specifications allow customers to engage in more in-depth analysis of the ECT alternative. This lets the customer instantly check the electrical and mechanical specification of ECT’s recommended probe match and to compare critical parameters to verify compatibility.

Tony DeRosa, Product Manager, explains: “Our proficient engineers compiled the data for this tool, which leverages ECT’s extensive knowledge of spring probes along with our applications experience to allow us to accurately recommend conversion to ECT probes.”

Best Temperature Accuracy for Testing of High Pin Count Packages

Multitest MT9510 Pick-and-Place Handler available with additional temperature control features

The Multitest MT9510 pick-and-place handler is now available with an optional active socket purge (ASP). The ASP is another feature to support the excellent temperature performance of the well-established MT9510 test handler.

By applying thermal controlled air flow to the pins the ASP keeps the temperature contact pin in the socket at the set test temperature. ASP provides optimum thermal energy to device under test and reduces the energy losses during test significantly. Particularly for high pin count devices this has a substantial influence on the overall temperature performance and therefore reduces the temperature calibration efforts.

Syariffuddin Kamarudin, Product Manager MT9510, explains: “With ASP we extend our temperature control features for the MT9510. This is especially important for the automotive market where strict requirements for temperature accuracy are in already in place. The MT9510 with ASP will support our customers to improve quality and yield.”

Multitest Atlas Contactor Brings Advanced Electrical and Mechanical Performance to WLCSP Testing

Atlas 0.3 mm pitch spring probe for reduced cost of test

Multitest’s Atlas contactor with 0.3 mm pitch responds to challenging requirements in WLCSP testing. The Atlas 030 high performance WLCSP test contactors are designed to meet the electrical requirements of today’s testing environment, without sacrificing mechanical performance. Long probe life, combined with improved first pass yields and easy WLCSP probe replacement in test fixtures and probe heads, significantly contributes to a lower cost of test.

The Atlas 030 contact profile is critically important to achieving high bandwidth, low contact resistance, long life and high reliability. The Atlas 030 offers a shorter electrical path, lower capacitance and inductance, and increased tip rigidity with a much greater immunity to breakage than traditional WLCSP probes used in earlier-generation test sockets. The Atlas 030 has 0.310 mm of compliance for bump structures that requires a larger compliance window for reliable contacting in high parallel test applications.

The Atlas 030 contactors are designed to meet standard sizes and footprints. This makes Atlas 030 an efficient and easy to install solution for replacing other WLCSP test sockets in a variety of applications. Atlas 030 supports both manual and automated contacting of WLCSPs. The Atlas 030 combines Multitest’s proprietary precision manufacturing process for producing smooth sub-micron features with an innovative cruciform tip design for optimum electrical and mechanical performance.

Bert Brost, Product Managers, explains: “Spring probes are emerging as the wafer-level chip scale package (WLCSP) contacting technology of choice. Spring probe WLCSP contactors and probe heads provide high bandwidth, low and repeatable contact resistance, with increased compliance and are easily maintained by our customers. The Atlas 030 is our response to the need of our customers for improving mechanical and electrical performance in WLCSP testing without increasing the cost of the interface.”
