Rohde & Schwarz
Improving PCBAs Quality and Advancing Smart Factory
Overview
Rohde & Schwarz Messgerätebau GmbH in Memmingen is a key manufacturing facility producing electronic test and measurement instruments, as well as products for the broadcast and media, aerospace and defense, and network and cybersecurity sectors. The plant in Memmingen produces approximately 1,800 different assembly types of printed circuit board assemblies (PCBAs) each year, combining flexibility in high-mix, small-lot production with high-quality manufacturing. However, as boards have become smaller and more densely populated, challenges have emerged that conventional inspection equipment struggles to address. To address these challenges, Rohde & Schwarz introduced SAKI Corporation’s 3D SPI and 3D AOI systems to improve inspection quality and advance smart manufacturing.
Why Rohde & Schwarz Chose SAKI
Rohde & Schwarz was seeking an inspection system capable of meeting increasingly demanding PCBAs inspection requirements for at least the next 10 years. In addition to improved inspection accuracy and speed, the company prioritized comprehensive data analysis capabilities, support for smart manufacturing, and greater operational efficiency.
SAKI’s 3D SPI and 3D AOI systems were selected as a solution that comprehensively met these requirements.
- Unified platform: Shared hardware and software across SPI and AOI reduce operating costs and simplify inspection programming.
- High-precision 3D inspection: Precise 3D measurement using multi-frequency projectors and high-resolution cameras.
- High-speed image acquisition: Image processing is 1.7 times faster than before.
- Offline programming: Inspection programs can be created and edited without stopping production.
Comments from Gerhard Martl of Rohde & Schwarz
“We produce 1,800 different types of PCBAs each year and need to create at least 3,500 inspection programs. With SAKI’s solution, we can perform debugging offline and create programs for PCBAs. We also expect it to be highly effective in reducing false calls.he end, Saki simply was the most convincing with their solution. The challenges we presented Saki with were cycle times and the reduction of pseudo defect rates. That was the most important thing for us.”
Results and Benefits
The implementation of SAKI’s 3D inspection solution has delivered the following benefits.
Improved Inspection Quality
High-precision 3D inspection is now possible for smaller, more densely populated components and large boards with warpage. Projectors covering four directions and high-precision 3D measurement technology have improved inspection quality in areas that were previously difficult to inspect.
Improved Production Efficiency
Programs can be created and edited offline without stopping the production line. High-speed image processing also reduces inspection time, helping the plant better accommodate high-mix, low-volume production.
Reduced False Calls
An intuitive review screen using 3D images enables operators to analyze defects more accurately. The company has set a target of reducing false calls by 50%, with efficiency gains expected across the inspection process.
Looking Ahead
Through its partnership with SAKI, TQ Group will continue to optimize its electronics manufacturing processes and introduce sustainable, state-of-the-art solutions. By combining their strengths to achieve high quality, the two companies will deliver even greater value to customers.
SAKI Corporation will continue to support TQ Group’s efforts to improve quality and maintain flexible manufacturing through its inspection technology and software.
