Company Overview
The organization develops automated optical inspection equipment and machine vision platforms for electronics manufacturing environments where production quality depends on accurate and repeatable visual inspection. Its systems support applications such as solder defect detection, component placement verification, optical character recognition, optical character verification, and quality inspection across PCB and SMT production lines. Future inspection platforms are being designed around higher resolution imaging, larger datasets, and AI assisted algorithms that can address increasingly complex electronics assemblies.
The Challenges
Scaling Processing Across Inspection Workloads
Modern AOI equipment must manage more than image capture because each inspection cycle can involve image preprocessing, defect analysis, application logic, machine control, and communication with other production equipment. High resolution imaging increases the amount of data that the processor must handle while inspection cycle times remain critical to manufacturing throughput. The equipment manufacturer therefore needed a CPU platform that could scale across different inspection performance requirements without requiring a completely new computing architecture.
Moving High Resolution Camera Data
High resolution AOI cameras can generate substantial amounts of image data as they capture the fine details needed to identify solder defects, incorrect component placement, markings, and other manufacturing inconsistencies. The planned machine architecture uses two high resolution 10GbE cameras, creating a need for high bandwidth network connectivity between the vision system and the inspection computer. Sufficient networking capacity helps prevent image transfer from becoming a bottleneck as inspection resolution and data volumes increase.
Expanding AI and Vision Acceleration
AI based inspection introduces additional processing requirements alongside conventional machine vision algorithms. The equipment manufacturer needed the flexibility to integrate a discrete GPU for inference while retaining expansion options for other vision hardware or specialized interfaces. A platform with limited expansion could restrict the ability to introduce more advanced AI models or vision technologies as future AOI requirements evolve.
Handling High Resolution Image Data
AOI applications may simultaneously work with captured images, reference datasets, AI models, inspection records, application data, and temporary processing files. Higher image resolution and parallel processing increase both memory utilization and demand for responsive local storage. The computing platform therefore needed substantial system memory and NVMe storage support to accommodate increasingly data intensive inspection workloads.
Integrating Computing Into the AOI Machine
AOI manufacturers typically design the computing subsystem as part of a larger proprietary machine rather than installing a fixed general purpose computer. Mechanical layout, cooling, power delivery, camera connectivity, expansion hardware, and service access can differ across machine configurations. A motherboard level platform gives engineers greater control over how computing hardware is integrated into the final inspection system.
The Solution
Premio’s AMD AM5 ATX industrial motherboard (CT-AR701)
A Flexible Foundation for AOI Machine Design
The CT-AR701 provides an ATX industrial motherboard platform that can be integrated directly into the equipment manufacturer’s proprietary AOI architecture. Engineers can configure processor, graphics acceleration, storage, cooling, power, and additional expansion hardware according to the performance requirements of each inspection platform. Its ATX form factor measures 305 mm by 244 mm, providing a standardized mechanical foundation for system integration.
Scalable AMD AM5 Processing
The CT-AR701 supports AMD EPYC 4005 and 4004 processors as well as Ryzen 9000 and 7000 Series desktop processors with support for processor configurations up to 170W TDP. This allows the AOI machine builder to select CPU performance according to workloads such as high resolution image preprocessing, inspection algorithms, system control, user interfaces, and application software. A common AM5 platform also gives engineering teams flexibility when developing multiple AOI performance tiers around a related hardware architecture.
High Bandwidth Vision Connectivity
The CT-AR701 includes two Broadcom BCM57412 10GbE LAN interfaces with SFP+ connectivity in addition to two Intel I210AT Gigabit Ethernet interfaces. In the planned AOI architecture, the dual 10GbE interfaces provide the network bandwidth needed to support large image data transfers associated with two high resolution 10GbE machine vision cameras. This gives the inspection platform a high bandwidth path for moving detailed vision data into the computing system for image processing and AI analysis.
The motherboard datasheet confirms the dual 10GbE SFP+ interfaces, while compatibility with a specific 10GbE camera model depends on the camera interface, network configuration, transceiver or cabling requirements, and software environment.
Flexible AI and Vision Expansion
The motherboard provides two PCIe x16 slots with Gen 5 support together with an additional PCIe x4 open end slot and a PCIe x1 connection. This expansion capability gives the AOI system designer room to integrate a discrete GPU for AI inference or other compatible hardware required by the vision application. GPU acceleration can support demanding workloads such as defect classification, component verification, OCR, OCV, and learned image analysis while allowing the platform to evolve with future inspection requirements.
Memory and Storage for Vision Data
Four DDR5 UDIMM sockets support up to 192GB of non ECC system memory, providing capacity for high resolution image datasets and parallel inspection workloads. The CT-AR701 also includes two M.2 M Key 2280 slots with PCIe x2 connectivity and support for NVMe storage. Together, these resources can support image buffering, AI models, inspection records, application data, and temporary processing datasets within the AOI platform.
The Benefits
Process High Resolution Vision Data Efficiently
Dual 10GbE SFP+ connectivity provides high bandwidth networking for transferring large amounts of vision data from the planned high resolution imaging system into the inspection computer.
Add GPU Accelerated AI with Flexible Expansion
PCIe Gen 5 expansion gives engineers the flexibility to introduce discrete GPU acceleration for AI based defect inspection while retaining a configurable motherboard architecture.
Scale Future AOI Systems on One Compute Platform
Scalable AMD processor support, up to 192GB DDR5 memory, NVMe storage, and PCIe expansion provide a common computing foundation that can support different AOI performance requirements and future inspection workloads.
