InCarrier Loader plus Dedicated to High Volume Production

Multitest launches the next generation loader for test in carriers

Multitest is launching the first InCarrier Loader plus with the shipment to a major IDM with high volume production in Europe and Asia.
The InCarrier Loader plus is the new state-of-the art loading solution for test in carriers. It is designed to optimize the back-end process at high volume production sites. The InCarrier Loader plus supports device loading to carrier from standard back-end transport media in a most cost-efficient and productivity-oriented way.

Since Multitest introduced the InCarrier concept to leverage the advantages of strip handling for singulated packages, this process has been well-accepted in the market. Up to now more than 3 billion packages were tested on InCarrier set-ups. The customers fully benefit from the robust, high parallel test solution. The advantages are particularly recognized for large production lots, long test times and/or small packages.

The InCarrier Loader plus is minimizing cost of loading and increases throughput up to 16,000 units per hour depending on packages sizes. The InCarrier Loader plus has been optimized for smaller footprint and requires less space on the test floor. The InCarrier Loader plus is supporting standard back-end transport media – such as JEDEC trays and bulk – and can be smoothly integrated in state-of-the-art production flows and lines. On the test floor the InCarrier Loader plus / InStrip solution can be combined with standard final packaging equipment for tape & real, tube or tray output and fits therefore seamless into the production process.

Andreas Nagy, Senior Director Marketing commented: “Multitest was the first supplier who actually offered the test in carrier solution – the first Multitest InCarrier Loader / Unloader was launched as a dedicated loading and unloading tool. The InCarrier Loader plus leads this concept to the next level of overall productivity improvement. This gets achieved by significant loading cost reduction at the InCarrier Loader plus and the elimination of the additional unloading steps, because the trays with the tested devices will be processed directly by traditional final packaging equipment for high volume production.”

Cost-efficient and Flexible Solution for Managing Power Dissipation

Multitest ATC for the MT2168 Pick-and-Place Handler

The Multitest ATC option for the MT2168 pick-and-place handler offers a most cost-efficient and flexible solution for managing low to medium range power dissipation at multisite test cells with up to 16 sites. Multitest ATC is an easy add-on to the standard MT2168, which can be mounted and demounted effortless. Multitest ATC is an affordable, reliable and flexible solution for test development and high volume production.

In the past power dissipation was recognized as an issue for high performance server, processor and graphic applications. Today package density and integration increases more and more to achieve higher speed and save space particularly in mobile applications. The power dissipation here is significantly less than in the high performance applications. However, thermal stress may damage the packages, temperature test may be distorted and test repeatability and yield lost. Additionally, there is a higher cost pressure for this market, which requires best cost of test configurations.

Multitest meets this need for managing power dissipation with the ATC add-on to the MT2168. No dedicated equipment is required, but all ATC functions are delivered by parts of the conversion kit. The operation is unchanged to a standard set-up and no dedicated training or spare part management is needed.

The Multitest ATC ensures highest flexibility. It can easily be mounted, demounted and changed to other MT2168 handlers in the field. Any standard MT2168 can be configured with this add-on, but will be available for standard test again once the add-on will be removed.

MT2168: Package Characterization at Cold Conditions

Leveraging the benchmark for ambient/hot test for tri-temp qualification

The Multitest MT2168 pick and place handler now offers the ability to characterize devices at cold conditions. This addresses the evolving requirements for temperature performance driven by applications in the end markets. Whereas final test of the respective devices in high volume production will only be done at ambient/hot, they need to get qualified for cold conditions before they ramp. The “Cold for Characterization” option of the MT2168 allows for using the one platform for qualification and final test without the need to invest in more complex and more expensive tri-temp test equipment.

The “Cold for Characterization” set-up of the MT2168 is an add-on to the standard base unit, which does not require changes in the handler itself. All required features are part of the conversion kit set. The customer can decide, whether he wants to use existing external chillers or if he prefers to have a LN2-based heat exchanger integrated. The “Cold for Characterization” option provides temperature conditioning directly at the contact site and sticks to the chamberless concept of the MT2168. This way no icing issues or defrost needs occur.

Günther Jeserer, Vice President for Gravity and Pick & Place Handling explains: “The MT2168 ‘Cold for Characterization’ meets the needs of the qualification teams at our customers: They can rely on the ease-of-operation of ambient/hot system but can do their full temperature characterization. With changing temperature performance requirements in the consumer markets and new car convenience and car entertainment applications in the automotive market, we anticipate a shift from strict tri-temp test in volume production to cold qualification before ramping. The MT2168 is the only handler with this ability, which is well received by our customers.”
