[Case Study] Inspection of Large PCBs for Communication Infrastructure and Servers
TAKAYA APT Series
Please utilize Takaya's flying probe tester for the inspection of large circuit boards for communication infrastructure and servers.
In large-scale board inspections for communication infrastructure and servers, jig-less inspection is particularly effective. Even with large board sizes, it can be handled efficiently, and this inspection method, which combines flexibility and precision, contributes to quality improvement and cost reduction. This greatly contributes to ensuring reliability in the fields of communication infrastructure and servers. 【Implementation Results】 - Established inspection technology tailored to the quality requirements specific to large boards. - Guaranteed the reliability of high-precision boards used in communication infrastructure devices and server products. 【Challenges Faced by Customers】 Handling of large boards: With jig-based testers, designing and manufacturing jigs for large boards is difficult. Due to weight and handling constraints, setup times become longer. Response to design changes: Large boards have many test points, and the cost of modifying jigs increases during design changes. The flexibility of the inspection process is low, making it unsuitable for low-volume, high-variety production. Cost and storage space: Jigs for large boards are expensive to manufacture and take up storage space. When operating multiple product lines, managing jigs becomes complicated.

basic information
**Benefits of Introducing Flying Probe Testers** **Efficiency through Elimination of Fixtures:** By implementing fixture-less inspection, there is no need for fixture production and storage even for large PCBs, leading to cost reduction. Flexible inspection is possible regardless of PCB size. **Addressing Challenges Specific to Large PCBs:** Using equipment capable of extensive inspection allows for reliable examination across the entire surface of the PCB. Facilities specialized in handling large PCBs reduce setup time. **Visualization and Traceability of Inspection Data:** Inspection results are quantified for each component and inspection point, enabling detailed quality control. It becomes easier to identify defective areas, contributing to quality improvement. **Quick Turnaround:** Rapid inspection responses can be made for design changes and new products. This shortens product launch periods and meets the speed demands of the market.
