GSI Group to Showcase the SVS™ Ascent,
a New Platform for SMT Inspection System,
at APEX/IPC, Booth #1008

WILMINGTON, MA, USA, February 13, 2007 — Next week at APEX/IPC, GSI Group Inc. (Nasdaq: GSIG) will unveil the SVS Ascent, a completely new platform for in-line, 3-D SMT inspection of solder paste depositions and component placement for process control. With a new level of speed, accuracy, and flexibility, the Ascent raises the bar in terms of 3-D SMT inspection price/performance for boards up to 50.8 x 61.0 cm (20 x 24 in.).

Based on a new, completely modernized platform, the SVS Ascent features the Gen4, an all-solid-state laser scanning platform with a fast 8 MHz data acquisition rate, all digital processing, and 8X oversampling. The Gen4 imaging system is built on the technology that pioneered 3-D inspection in the SMT industry: SVS’s patented laser scanning and triangulation technique. The data acquired by the Gen4 is analyzed pixel by pixel, without merging or blending areas of acquired data, resulting in the most accurate 3-D inspection results, distilled in real-time into easy-to-use process data.

Also new with the Ascent, SVS provides streamlined programming, which allows panel set-up from CAD data within 10 minutes. In the absence of CAD data, manual programming ability allows for creation of new programs or the editing of existing programs. Only SVS offers this range of programming options.
The SVS Ascent is the most robust solution for SMT inspection available today. It detects flaws in volume, area, height, X/Y position, coplanarity, and bridging. It can handle odd-shaped parts, call up inspection programs from bar code data, connect to SPC software for data analysis, automatically compensate for board warpage, and provide consistent results regardless of changes in lighting or board color.
