As the objects to inspect/measure in high-tech manufacturing become smaller, higher-resolution cameras with better spatial resolution can improve accuracy and precision. This requires a high-quality machine vision camera design, or what is now called a metrology camera. 3D measurements in particular pose increasing demands on camera performance and reliability.
The BASTION project was initiated on April 1, 2014 with the main of objective to research and develop new applications for the Broadcast Market, and for the Security and Surveillance Markets. Both will be built on top of the Internet Protocol network, which will allow distributing the video over several physical sites. The cameras will be located on one or more sites, and the monitoring/control room will be on a separate site. The main benefit of this distribution is that it will enable:
We recently published several articles about how OEM metrology cameras can help you make a performance leap with your process control system. Here are some details about how high resolution cameras are increasing throughput and accuracy for semiconductor and electronics metrology and inspection systems.
In our post about detecting smaller features with metrology cameras, we made the designation between mainstream machine vision cameras and industrial metrology cameras. [See slide 7 in Yole Developpement's Machine Vision Market report presentation]. Here are some more details on when a metrology camera will provide a performance advantage.
In semiconductor and electronics manufacturing, there has been a move towards 3D measurements to provide accurate process control of smaller dimensions for higher yield and quality of new packaging technologies. For example in electronics manufacturing a 2D view from the top only allows for detection of defects such as shifts, rotations, and cracks, but not whether components are flat on the board or the volume of solder paste.
As chipmakers continue to move to smaller technology nodes, there are greater demands on process control systems to inspect and measure smaller features and components.
There are many more medical applications relying on machine vision cameras. Check out how OEM industrial cameras are used in FFOCT-based endoscopes and in cataract surgery systems:
Once you have determined the right camera parameters that provide the necessary image information for your measurement, there are a few more considerations that can affect the overall performance of the system. The cameras also needs to meet incoming supplier inspection requirements such as cleanliness, not require extended set-up time, enable tool matching and easy replacement in the field, and not impact the system up time. These extra factors will help with some of those intangibles that come with critical component selection and as a bonus make your coworkers a little happier.
The LENSAR™ Laser System offers cataract surgeons precision and accuracy, while optimizing overall visual outcomes. The LENSAR™ Laser System is one of the only femtosecond lasers built specifically for refractive cataract surgery. Because it was designed from the ground up, every aspect of the laser has been purposefully designed to meet the needs of cataract surgeons.
The constant challenge in semiconductor and electronics manufacturing is to increase throughput while also increasing accuracy with shrinking dimensions. This means in-line inspection and metrology systems must provide 100% analysis at a high precision while maintaining high throughput. The latest innovations in ultra high-resolution image sensors and subsequent cameras support these goals. High resolution, high-speed metrology cameras enable greater throughput in semiconductor or electronics inspection and metrology systems through:
