Silicon Turnkey Solutions and Credence Partner to Deliver Wireless Test Solutions With Diamond 40RF

MILPITAS, CA , a provider of test solutions for the worldwide consumer semiconductor industry, announced today that Silicon Turnkey Solutions (STS) Inc., a leading-edge provider of Specialty Assembly, Reliability, Qualification and Electrical Test services, will expand its ATE capabilities with the addition of the Diamond(TM) 40RF (D40 RF) platform from Credence.

Effectively immediately, STS customers will be able to leverage Credence-assisted test solutions including RF, digital and mixed signal. STS is making test development capabilities available to manufacturers of cost-sensitive IC devices such as wireless baseband, microcontrollers, display controllers, RF SiP devices, Bluetooth devices, MEMs, and integrated wireless transceivers used in popular consumer electronic products.

STS engineers are trained on all Credence test platforms, including the Diamond, ASL and Sapphire. The partnership is developing an expert resource pool for applications program development, correlation, translation tools, and loadboard design. Currently in development are quad-site baseband applications and GPRS device tests on the D40 RF for joint customers of STS and Credence.

"Our partnership with Credence makes it possible for us to move strategically towards the convergence market. We will be able to offer value-added solutions that deliver leading RF technology and price performance. This is especially advantageous for engineering-driven OSAT companies with budget constraints," said Zef Malik, chief executive officer of STS. "We believe Credence will be a strategic collaborative partner that will enable us to deliver to our customers time-to-market and time-to-volume requirements and achieve rapid and profitable deployment of their devices."

"Our customers need to quickly and economically develop their new test requirements and will then drive volume production to the OSATs and subcontractors, where our products have achieved a critical mass. STS is recognized as a leader in providing innovative and cost competitive turnkey solutions for complex and highly integrated packages," said Amir Aghdaei, senior vice president of worldwide field operations and marketing for Credence. "This partnership provides an excellent solution for many of our very cost-sensitive customers who want to be engaged through the entire value cycle, development through production."

The Diamond 40 test system combines analog, digital, mixed signal, and RF test instrumentation to support a wide range of consumer IC device testing. Incorporating Credence's proprietary MVNA(TM) (Modulated Vector Network Analysis) technology, the D40 RF adds wireless test capabilities for mobile phone, WLAN, WiMAX and ZigBee devices. Offering from 10 to up to 40 slots, the D40 RF supports over 3000 pins for very large ASIC testing, or massive multisite test requirements ( > 16 sites). The D40 RF can expand to ensure a match of system capability to test requirements. The D40 RF leverages the common instrument suite and software available in the Diamond series.

STS and Credence will jointly host a series of seminars and enable customers to participate in live demos. The companies will begin a series of seminars and open houses to demonstrate their solutions beginning Thursday, June 26, 2008.
