Advanced Features Of High Speed Digital I/O Devices: Double Data Rate


As clock speeds and data rates continue to increase, designers of digital integrated circuits are creating new ways to maximize the rate of data being sent into and out of digital devices. One such method is known as double data rate (DDR). With single data rate (SDR) devices, data is latched on either the rising or falling edges of the sample clock. A DDR device latches data on both the rising... » read more

Addressing High Precision Automated Optical Inspection Challenges With 3D Technology


Driven by the continued decrease in the size of electronics packaging, combined with the increase in density, there is a critical need for highly accurate 3D inspection for defect detection. Using multi-view 3D sensors and parallel projection, it is possible to capture more of the board at a faster rate as compared to serial image acquisition which is more time consuming. Precise 3D image re... » read more

Thinking Differently About IIoT Analytics


Manufacturers are rushing to keep up with the latest technology trends and perhaps the most significant ones are around the smart factory. Whether you call it Industry 4.0, Smart Manufacturing or the Industrial Internet of Things (IIoT), what all these initiatives have in common is the desire to maximize value from manufacturing data and improve overall manufacturing efficiency. With the ave... » read more

Test Moving Forward And Backward


Test, once considered an important but rather mundane way of separating good chips from the not-so-good and the total rejects, is taking on a whole new life. After decades of largely living in the shadows behind design and advancements in materials and lithography, test has quietly shifted into a much more critical and more public role. But it has taken several rather significant shifts acro... » read more

Data Confusion At The Edge


Disparities in pre-processing of data at the edge, coupled with a total lack of standardization, are raising questions about how that data will be prioritized and managed in AI and machine learning systems. Initially, the idea was that 5G would connect edge data to the cloud, where massive server farms would infer patterns from that data and send it back to the edge devices. But there is far... » read more

Tessent Hierarchical ATPG Reference Flow for Arm Cortex-A75


Arm and Mentor have jointly developed a reference flow for a hierarchical DFT and ATPG implementation with Tessent for any Arm subsystem based on Cortex A-series IP. The reference flow, described in this paper, provides documentation, seamless interfaces, and scripts that accelerate the implementation of a hierarchical test solution. Arm and Mentor are dedicated to enabling customer success, re... » read more

X-ray Detects Hidden Failure Modes


Functional testing and visual examination using stereo microscopy are today's 'standard' quality control techniques for characterising yield and workmanship-related issues in IC fabrication and electronics assembly. Currently used test methodologies—such as IPC-TM-650—rely heavily on visual examination. The visual detection of defects can still be difficult, as samples need to be inspected ... » read more

The 3 Big Data Mega Trends For Manufacturing


By Michael Schuldenfrei In today’s global, highly competitive economy, industrial companies are under intense pressure to lower manufacturing costs and streamline processes without compromising quality. Production managers are expected to contribute to improved business outcomes through ultra-efficient use of raw materials, near-zero production downtime, streamlined labor costs, and agile wo... » read more

Extending 3D MRS Sensor Technology To Address Challenging Measurement And Inspection Applications


There is an increasing need for highly accurate 3D inspection and measurement capabilities for applications in SMT, semiconductor and metrology markets. 3D Multiple Reflection Suppression (MRS) sensor technology has been effectively combined with Automated Optical Inspection for several years and is now being utilized for many SPI applications such as microelectronics and sub-100-micron sold... » read more

Inspection, Metrology Challenges Grow For SiC


Inspection and metrology are becoming more critical in the silicon carbide (SiC) industry amid a pressing need to find problematic defects in current and future SiC devices. Finding defects always has been a challenging task for SiC devices. But it’s becoming more imperative to find killer defects and reduce them as SiC device vendors begin to expand their production for the next wave of a... » read more
