Multitest MiCon® Contactor: Advantages of Cantilever Design for MCU and ASIC Testing

Significant Improvements in Overall Equipment Efficiency (OEE) Multitest recently launched the MiCon contactor. The MiCon leverages the industry-proven Cantilever technology for the final test of Microcontrollers, Industrial DSPs and Application Specific ICs. Evaluations at customer test floors showed substantial improvements in first pass yield, life span and cleaning cycles compared to spring pin solutions. MiCon fully supports the requirements of a high, stable and reliable production output at lowest cost of test. MiCon leverages the proven Cantilever technology for an architecture, which matches existing spring pin test boards and provides self-cleaning wipe. MiCon is a spring pin  footprint compatible alternative supporting advanced temperature requirements as well as advanced power/current requirements. The footprint compatibility allows for easy and cost-efficient conversion from spring pin setups. The fully decoupled load board side of the spring ensure no degradation of the load board pad. MiCon features a single piece design, which ensures a long lifespan, low and stable contact resistance, high current carrying capability and an extended temperature range. The MiCon allows for testing at full specification values. The extended operating range accommodates device lead trim and form variability such as device alignment accuracy and device lead coplanarity. Marcel Sans, Project Manager, explains: “The performance reports, received from the onsite customer evaluations, showed extraordinary advantages compared to the traditional spring pin solutions with a first pass yield of 99.8 %, time between cleaning cycles more than doubled and provided full contacting performance without signs yield degradations at high insertions counts, beyond the spring pins end of life.” To learn more about the Multitest MiCon contactor, please visit http://multitest.com/MiCon The post Multitest MiCon® Contactor: Advantages of Cantilever Design for MCU and ASIC Testing appeared first on xcerra.com.

Multitest Atlas Contactor Demonstrates Advanced Electrical and Mechanical Performance in WLCSP Testing

Atlas 0.3 mm pitch spring probe validated at customer site Multitest’s new 0.3 mm pitch Atlas contactor successfully passed a demanding customer production floor evaluation. The customer’s evaluation measures confirmed that the Atlas did reduce the customer’s cost of test while improving test yield and increasing throughput. Based on the evaluation results, the customer ordered a significant number of Atlas 030 contactors to support their new product WLCSP production ramp. The customer is a long time user of Multitest contactors and after reviewing the new Atlas design they were eager to evaluate it. It is the added strength of the Atlas cruciform tip that captured the customer’s attention.  Not only is the Atlas mechanically superior, the Atlas offers electrical performance that allows the customer to test to the true performance of the device. The evaluation ended with the customer placing an order for a significant quantity of Atlas 030 contactors. The key to the WLCSP Atlas’s high performance, high reliability and superior electrical contacting is the combination of increased mechanical tip strength and short probe electrical performance.  Atlas WLCSP test contactors achieve mechanical reliability with a rigid “cruciform” tip applied to Multitest’s QuadTech flat probe technology.  The Atlas 030 offers a short electrical path, with lower capacitance and inductance that is ideal for functional and AC parametric testing of WLCSP devices that require high system bandwidth and throughput gains in large multisite test applications. The cruciform tip provides increased tip rigidity with a much greater immunity to breakage than traditional WLCPS 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. Bert Brost, Senior Product Managers, explains: “We are very proud of the positive result of the evaluation. The evaluation by the customer confirmed what we already knew, the Atlas 030 contactor is a high performance solution for WLCSP testing.” To learn more about the Multitest Atlas contactor, please visit http://multitest.com/atlas The post Multitest Atlas Contactor Demonstrates Advanced Electrical and Mechanical Performance in WLCSP Testing appeared first on xcerra.com.
