Lifesaving Device Relying on Everett Charles Technology’s Probe Expertise

Chest Compression Device Deploys ECTs Pylon E-S series probe

Everett Charles Technologies (ECT) developed a custom version of the well-established Pylon E-S series spring probe, which is deployed in new generation chest compression devices for Emergency Medical Services and hospitals. The slightly modified Pylon E-S Series probe suits the harsh requirements for the lifesaving mission to assure the battery pack is continuously transferring power to the system.

The application requires a 100% reliable, no fail contact under all operating conditions.  In case of a low battery level the emergency team needs to replace the battery pack within seconds and make reliable contact instantly. The probe is air and liquid tight for hygiene and cleaning reasons and is capable of withstanding shock and vibe that occur during helicopter missions. The application requires an uninterrupted, continuous current of 4.0 A.

ECT and the customer jointly developed a robust solution by leveraging a well-established probe and thorough knowhow of precision machining of metals and plastics. In-depth electrical and mechanical analysis prior to hardware build validated the design and reduced development time.

Thomas Frenzel, Sales Manager Northern Europe, explains: “Based on this high-end and lifesaving application, the requirements have been one of the harshest we ever had to meet. Our solution replaces a competitive one, which failed at vibe test.”

Multitest Atlas Contactor Outperforms Competition:

Significant improvements in yield and life span

Multitest’s Atlas contactor with the recently launched Atlas 040 probe has demonstrated substantial advantages over a competitive solution in an onsite evaluation at a major Asian customer. Both test yield and probe life span were significantly increased and contributed to a sustainable cost of test improvement  for the entire test cell.

The Atlas contacting products are the next generation of Multitest’s revolutionary QuadTech flat probe technology. The Atlas 040 is a high performance contactor designed for 0.4 mm pitch WLCSP and large BGA ball count device-under-test contacting applications. The Atlas 040 was configured as part of a quad site setup with a LTX-Credence Diamond10 tester.  The Atlas 040 contactor delivered a 25% longer life for the customer with 250K insertions and first pass yields were increased by 4 percentage points. With these results the Atlas contactor clearly met the customer’s criteria to increase yields, increase system uptime, and reduce costs. After this successful evaluation the Atlas was designated the customer’s contacting solution of choice.

Bert Brost, Product Managers, explains: “The development of the Atlas probe was driven by the customer’s need for a low cost probe that has the strength and reliability of a radial probe but at a fraction of the cost. The measurable focus was low cost, high bandwidth, long life, with low and repeatable contact resistance. Higher test yields and longer probe life directly translate into less test capacity required for retest, higher system uptimes and a significantly increase in the number of shipped devices.”

High Multi-Site Test of Pressure Sensors

Xcerra’s test cell for pressure sensors leverages the new InPressure HD module

Xcerra recently shipped a complete test cell for pressure test, which combines the new InPressure HD module for high pin count pressure test up to 16 bar with an LTX-Credence Diamondx tester, a Multitest InStrip test handler, Xcerra test interfaces and a third party pressure supply unit. In addition to the hardware, Xcerra developed the test program and provided full integration and validation services.

The customer is benefiting from the high-throughput capability of the Multitest InMEMS/InCarrier solution and the cost-efficiency of LTX-Credence Diamondx tester. The new InPressure HD module, which is an advanced version of the existing InPressure module, fully supports high multi-site test of high pin count devices with up to 2,268 signal lines.

The customer received a fully integrated and validated test cell for pressure sensor calibration, trim and test, providing fast time-to-volume and optimal OEE and yield. One of the advanced features of the integrated test cell is the ability of the handler to go through temperature calibration in the field by executing a setup calibration routine using the Diamondx tester.

Andreas Nagy, senior director, Test Cell Innovation, comments, “Very early in the engagement the customer made clear that they would only select a full test cell solution for their absolute pressure sensor targeted at automotive applications. The Xcerra solution, combining strip-like parallel testing of singulated packages to achieve full traceability at highest throughput and all the benefits of a test cell offering, including the application development and validation, exactly met the customer demands.”

Small Packages on Multitest Pick and Place Handlers

Multitest MT2168 and MT9510: Ready for Packages below 3 x 3 mm

Multitest expanded the package range for both pick and place handler platforms – the MT9510 and MT2168 to devices smaller than 3 x 3 mm. The expanded package portfolios of the MT9510 and MT12168 go beyond the typical ranges of established pick and place systems

Multitest’s industry-leading handling solutions for small sized devices fully maintain the proven temperature and multi-site test capabilities. This combination makes the Multitest pick and place handlers the platform of choice for high volume application, which not only require reliable handling of small packages with high yield, but also best accuracy and stability in the full tri-temp range.

Multitest has installed multiple pick and place handling systems leveraging this new package range in Asia and Europe.

atg Luther & Maelzer to exhibit at TPCA Show 2016

Leading test solutions for bare boards and substrates

atg Luther & Maelzer will exhibit the new A7-16 flying probe test solution, for oversized boards, as well as, the high speed substrate test solution, S3-8, at the upcoming TPCA Show scheduled to take place October 26 – 28, 2016 at the Nangang Exhibition Center in Taipei, Taiwan.

The A7-169 test system is the optimum solution for high speed and high throughput testing of backpanel and server boards. The A7-16 can be

configured with 16 to 24 test heads and up to 12 cameras for optical alignment. Depending on the number of test heads, the test area is 24” to 39.9” (610 mm x 1000 mm) or 27″ to 59,2″ (670 mm x 1500 mm). The system features the latest direct linear drive technology delivering high accuracy and fast test speed for large format boards. For flexible boards a tension option is available. Please visit for more information.

The S3-8 10µm substrate tester meets the challenging requirements of high end substrate test, which include positioning accuracy and a high number of contact points, by applying the advanced flying probe technology of atg Luther & Maelzer. With its double-sided, eight test heads architecture the S3-8 achieves a substantially higher speed. This high throughput capability enables testing of high quantities of substrate boards using flying probe test systems providing the customer with an economical test solution.
