Speedline Technologies Receives Patent for Enhanced System of Post-Print 2D Inspection of Circuit Boards - MPM BridgeVision® System Reduces Scrap, Rework With Effective Quantified Bridge Detection Solution
Speedline Technologies, Inc. (http://www.speedlinetech.com) has been awarded U.S. patent #6,738,505 for its invention of the texture-based method of analyzing potential bridge defects on circuit boards during the post-print inspection process.
FRANKLIN, MA (PRWEB) September 20, 2004 -- Speedline Technologies, Inc. (http://www.speedlinetech.com) has been awarded U.S. patent #6,738,505 for its invention of the texture-based method of analyzing potential bridge defects on circuit boards during the post-print inspection process.
Introduced by Speedline in its MPM BridgeVision® system, the patent-winning technique assesses the quality of paste deposits utilizing texture-based image acquisition algorithms and a digital camera system. The system is integrated with the contrast-based 2D paste inspection option for the post-print review of printed deposits inside the printer.
The new technology reduces scrap and rework costs by identifying defective and borderline products and preventing them from continuing through the assembly process. The BridgeVision system is immediately available as an option on new -- and as an upgrade to installed -- Speedline MPM AP Excel and MPM AP HiE printers running Windows NT.
The patent was awarded for the method of using texture in the detection of paste in the region of interest between the printed deposits. Prior to our innovation, manufacturers had to either rely on contrast-based methods, where the difference between the pasted deposit and the solder mask was insufficient for repeatable or rapid measurement, or they were compelled to purchase expensive 100-percent 3D AOI systems," said Dr. Gerald Pham-Van-Diep, Director, Advanced Development at Speedline Technologies. With the BridgeVision system, manufacturers now have a cost-effective option that repeatedly quantifies bridge-like features and is fast enough to allow for inspection of their critical devices."
Additional features of the BridgeVision system include:
| | - Advanced texture-based image acquisition technology that eliminates false positive detections associated with contrast-based bridge detection systems;
- Error alarms driven by both spike penetration and percentage gap covered measurements;
- Automatic initiation of stencil cleaning based on inspection measurements; and a
- Digital camera that supports highly accurate defect assessment.
- GUI settings to allow for user defined limits for SPC control

By quickly and efficiently identifying and preventing defective product from continuing through the assembly process, Speedline is demonstrating its technology and process leadership in reducing cost, waste, and inefficiency from the production process," Pham-Van-Diep said.
