The "Picking Sensor" illuminates the small boxes of parts to be assembled, preventing the accidental selection of incorrect items. Additionally, by synchronizing this sensor with the system, it is possible to reduce various labor costs and improve quality. 【Effects】 ■ Prevention of Incorrect Assembly of Different Items The box designated for picking lights up according to the system instructions, allowing the worker to quickly pick the next part to be assembled. ■ Standardization of Work Procedures Since picking can only be done according to the specified procedures in the work instruction manual, it prevents variations in work performed by different workers. ■ Assembly Instructions with Appropriate Tools By synchronizing the tools with the system, work instructions can be provided using only the appropriate tools. Example: It is possible to ensure that picked screws can only be assembled with an electric screwdriver set to the appropriate torque. ■ Reduction of Visual Inspection Workload Since incorrect assembly of different items is not possible, it reduces the need for visual checks during assembly inspections to confirm incorrect assembly.

After the assembly work is completed, the inspection of finished products can be digitized through inspection instructions on a tablet and touch checks, which also aids in various data management. ■ Inspection instructions from the tablet Even inexperienced workers can perform inspections according to the instructions. Additionally, it helps prevent skipping inspection tasks. ■ Paperless check sheets By using a touch interface on the tablet instead of handwritten records for inspection check sheets, the labor required for recording inspection data can be reduced. ■ Automatic management of manufacturing serial numbers Since serial number data can be centrally managed from the functional inspection machine, reliable traceability after shipment is possible. ■ Production plan progress display With touch-based inspections on the tablet, the production progress of inspectors and the status of achieving production plans can be understood, which helps improve the accuracy of subsequent production plan creation and consideration. ■ Defect recording and change point management Real-time aggregation of defects can be done as inspection records, allowing data to be utilized for change point analysis and management.

Significantly contributes to improving assembly quality on the SMT assembly line! By introducing a humidification system even during dry seasons, we can manage stable temperature and humidity throughout the year, ensuring consistent assembly quality and effective static electricity measures. 【Humidification Effects】 ■Improvement in Assembly Printing Quality Humidification makes it difficult for cream solder to dry out, improving solder printing adhesion. ■Reduction of Electronic Component Adhesion Errors Humidification increases the adhesion of electronic components on the mounter, reducing adhesion errors. ■Optimal for Static Electricity Measures! By humidifying, we can reduce static electricity generation, significantly contributing to the prevention of component damage caused by static electricity, which is the nemesis of electronic components!

Unidentified issues that cannot be resolved on the manufacturing site will be automatically sent to the analysis center through the "NG SYSTEM." At the analysis center, the details sent immediately are used to understand the nature of the issue and instruct the manufacturing site on how to respond. This has significantly reduced response times and is being utilized to improve quality. 【IoT in the Production Site (Excerpt)】 ■ When? ■ Who? ■ What? ■ How much time? ■ How many produced? *For more details, please refer to the PDF document or feel free to contact us.

In the setup process, necessary parts and appropriate set positions are instructed from a tablet, enabling accurate setup work. During the actual manual insertion work, even in simultaneous operations by multiple staff members, the work instructions are displayed on each dedicated touch monitor. Additionally, the work performance time from the start to the end of production is digitized for each production unit, aiming for improved efficiency and achieving high-quality work.

Defects that occur within the project are recorded not on paper but in an environment where they can be easily entered using a tablet, with just barcode scanning and tapping operations. This greatly contributes to a significant reduction in recording time and promotes a paperless environment. The accumulated defect data is analyzed immediately and fed back into the next production. [What does your company seek in PCB assembly?] ■ We want to shorten the development period while maintaining high quality and keeping costs down. ■ We are looking for a partner we can trust with quality and delivery times. ■ We would like flexible responses regarding production lots and delivery times. ■ We want support for small lots of various types. ■ We need urgent responses. *For more details, please refer to the PDF document or feel free to contact us.
