Expanding on Proven Solutions: New Sensor Test Module for Twin Axis Stimulation

Multitest has shipped new high g sensor test module for X/Z stimulation

Multitest shipped a new “Shaker” high g sensor test module for the MT9928. The module allows for twin axis testing in one stimulation on the x and z axis. The module expands the MEMS/sensor test portfolio for the flexible and modular MT9928 handler platform, which already includes multiple solutions for test and calibration of inertial MEMS/sensors.

With the kitable and modular MT9928 platform, in combination with dedicated MEMS/sensor test modules, the customer receives a highly flexible test setup which can easily be converted to different packages styles and MEMS/sensor applications.

The generic Multitest MEMS test approach deploys all features and functions of the standard handling system and addresses the MEMS specific requirements by adding MEMS/sensor test and calibration carts with dedicated stimulus boxes.

The new twin axis high g sensor test module is dedicated for X/Z stimulation of a MEMS device and allows for two axis testing in one stimulation. By applying one stimulation, cycle time can be saved and the packages need to be touched less often reducing the risk of damage during test. For testing at various temperature levels this advantage is even greater.

The twin axis X/Z high g module for the MT9928 gravity handler offers advantages in test time, test process optimization and flexibility, as well as, better equipment utilization. The module has proven best performance with less than 1.5 % THD at 14 g 100 Hz stimulation.

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.”
