In our quality assurance process, we inspect all products after assembly using an inspection sheet. We confirm the quality that has already been integrated into the standardized work processes at each stage. ★Manufacturing Number Management System★ A manufacturing number is assigned for each order. All work records, including process communication documents, are managed by the manufacturing number. In the unlikely event of a defect in market products, we can instantly identify the manufacturing period. ★Parts Information Tracking★ We centrally manage inventory data and parts receipt and dispatch that are always linked to the bill of materials for the circuit board in our inventory management system. Anyone can track parts information for each project. Any changes to parts are recorded in the bill of materials and stored for ten years. ★Shipping History Records★ We record the shipping method for each order. In the case of delivery, we import the tracking number and shipping information into our internal system, allowing for past tracking. When products are shipped, we notify customers with a shipping completion email. *For more details, please refer to the PDF document or feel free to contact us.*

We are developing the "Bridge Zero Movement" aimed at suppressing the occurrence of solder bridges and further improving product quality and productivity. Additionally, since 2009, we have initiated the "Business Manual Project" aimed at standardizing the work processes of all departments within the company to achieve quality that satisfies our customers. ★Bridge Zero Movement★ We compile data on solder bridges found in devices with a narrow pitch of 0.65mm or less during inspections after reflow. The reported bridges are investigated for their causes within the process, and measures are taken to prevent recurrence. ★Business Manual Project★ We visualize work procedures to check for any waste, inconsistency, or irregularity, and standardize them in the most efficient manner. The goal is to prevent variations in work quality due to workers' experiences and to consistently maintain a high level of quality. ★Regular Calibration of Measuring Instruments★ Maintenance of manufacturing equipment is carried out every weekend. All employees are engaged in organizing and tidying up the manufacturing environment on a daily basis. Soldering iron thermometers and voltmeters are regularly calibrated, and calibration results are recorded. *For more details, please refer to the PDF document or feel free to contact us.*

[PWB Implementation One Skill Quality Certificate] At Shinjitsu, we have established an internal soldering skill certification system since 2007 to improve the manual soldering techniques that are the foundation of implementation technology. An internal soldering skill certification committee has been formed, and those who have obtained the Advanced Operator Technical Certificate through the Japan Welding Engineering Society's soldering skill certification exam are appointed to train newcomers according to established procedures. ■ Pre-training Course To obtain certification, participants undergo several days of training conducted by qualified instructors from the Japan Welding Engineering Society. After systematically learning about the history of soldering, basic terminology, fundamental knowledge of printed circuit boards and electronic circuit components, and soldering evaluation criteria using textbooks, they receive practical training and take the exam. ■ Practical Exam In the practical exam, five items are comprehensively evaluated, including the degree of tilt of each component, lead forming, cleanliness, and required time. Upon passing, a certificate is awarded, granting the qualification to perform soldering work on customer circuit boards for the first time. *For more details, please refer to the PDF document or feel free to contact us.

Each customer's order will be assigned a production item number, and a process communication document will be issued to record the steps until shipment. After shipment, inquiries and product issues can be addressed at any time using the production item number. ★Assembly Completion Inspection★ All items after assembly will be inspected using an inspection sheet. The standardized work at each stage confirms the quality that has already been integrated into the process. The first lot will be recorded on standard format paper, and from the second lot onward, all records will be handwritten in a modified format of the standard template. This is stored within the factory for a certain period as work history, allowing for immediate reference at any time. ★Storage of Various Records★ Manufacturing records are kept from the history of parts and materials to inspection records. They can be searched and referenced immediately in response to customer inquiries. Records related to printed circuit board assembly, inspection logs, and inspection records of assembly site work are managed internally with unique identifiers, organized by model.
