rate as employees jump between com- panies, or become misaligned with their organizations. While leading industry organizations that include the IPC and SMTA are tackling the issue head-on with education and training programs, a need exists for equipment suppliers to cooperate with other industry leaders and organizations to adopt machine-to- machine (M2M) communication stan- dards. Initiatives, such as the IPC Connected Factory Exchange (CFX) and the IPC-Hermes-9852 standard, underpin the efforts within the industry, and many companies are working together to develop standards to create seamless production. Guided in part by Industry 4.0, these M2M com-

Far beyond an automatic line changeover, this bidirectional communication allows equipment to automatically adjust production parameters to increase board quality and lower costs by eliminating rework and scrap.

CableEye
Whether you're an R&D engineer designing cables for a new product or a production worker checking hundreds of cables an hour, CableEye's unique graphic wiring display tells you what you need to know clearly and immediately. Graphically see missing or shorted conductors, miswired cables, reversed diodes, twisted-pair errors, and backward connectors. Print crystal-clear test results including the wiring schematic. Graphically compare two cables by alternating the display between your test result and the ideal cable. Run a
rather than to the pad location. APC can identify shift trends and implement further position correc- tion by using true-3D measurement data from an AOI system.
Industry 4.0 Big Data is the foundation for Industry 4.0.
Advanced inspection systems must evolve from simply judging “pass/fail” tools into highly intu- itive, dynamic, decision-making systems, which emphasizes the need for reliable, traceable data. Artificial intelligence (AI) engines can empower

inspection market growth trajectory, we can see how process challenges helped to create innovations. For example, solder paste inspection (SPI) has undergone a shift from 2D to 3D, because the 2D inspection technologies manufacturers tradi- tionally used to collect solder deposit images could not solve shadowing problems. Thus, companies developed 3D SPI to capture the printed solder paste height to accurately measure the total volume of paste printed. Several years later, we see the same need for surface mount component
inspection with AOI systems. As today’s board complexity is increasing
with more components, more solder joints, higher density, and shrinking package technologies, such as 01005 (0402 metric) and even 008004 (0201 metric) microchips, 2D AOI technology using greyscale image analysis or angled camera view of color images may no longer be practical. Most deci- sions made are based on a “good-bad” comparison of reference images, which can easily be affected by variables like component surface finish, board con-
