1. Equipment Maintenance Processes

1.1 Pre - Maintenance Preparation

Conduct a comprehensive assessment of equipment status. This involves a detailed review of equipment operation records, fault history, and current performance parameters. By analyzing these data, potential issues can be identified in advance, allowing for more targeted maintenance planning. For example, if an FPC cutting machine has shown a gradual decrease in cutting accuracy over time, this information can be used to prioritize the calibration of relevant components during maintenance.

Prepare essential maintenance tools, spare parts, and technical documents. High - precision measuring tools are crucial for accurate calibration, and having the right spare parts on hand ensures that any faulty components can be replaced promptly. Technical documents, such as equipment manuals and maintenance procedures, serve as a guide for maintenance personnel, ensuring that they follow the correct steps and safety protocols.

Assign professional maintenance personnel with relevant qualifications and experience. Our team of maintenance engineers is well - trained in handling FPC, PCB, and rigid - flex board equipment. They undergo regular training to keep up with the latest technological advancements in the industry. Before starting any maintenance work, pre - maintenance training is provided to familiarize them with the specific tasks and safety requirements for the equipment at hand.

1.2 Routine Maintenance

Perform daily inspections on equipment. This includes a visual check of the equipment's appearance for any signs of damage or wear, such as scratches on the surface of a PCB drilling machine. The tightness of fasteners is also inspected to prevent any parts from becoming loose during operation. Moving parts are checked for proper lubrication to reduce friction and extend their lifespan. Electrical systems are examined to ensure normal operation, and any abnormal noises or fluctuations in power consumption are noted. All inspection results are recorded in detail for future reference.

Conduct weekly or monthly preventive maintenance according to the equipment maintenance plan. For FPC laminating machines, this may involve cleaning the laminating rollers to remove any residue that could affect the quality of the laminated FPC. Worn - out parts, such as filters in air - cooling systems or belts in conveyor systems, are replaced. Measuring instruments used in the production process, like thickness gauges for FPC, are calibrated to ensure accurate measurements. After the preventive maintenance is completed, the equipment is tested to ensure that it operates smoothly. All maintenance activities and test results are updated in the equipment maintenance records.

1.3 Fault Maintenance

When a fault occurs in the equipment, maintenance personnel respond promptly. They conduct on - site investigations, carefully observing the fault symptoms. For instance, if an FPC soldering machine experiences inconsistent soldering quality, the temperature control system, solder supply mechanism, and soldering tip condition are all examined. Based on the equipment's technical data and the observed symptoms, the cause of the fault is identified.

A fault repair plan is then developed. This plan includes determining the repair steps, such as whether it requires replacing a specific component or adjusting the equipment's parameters. The required spare parts are identified, and an estimate of the repair time is made. In some cases, the repair plan may need to be approved by a supervisor or relevant department to ensure that it aligns with the overall production schedule.

The repair plan is implemented following strict safety procedures. Faulty parts are replaced with high - quality spares, and equipment parameters are adjusted precisely. During the repair process, safety is of utmost importance. Maintenance personnel wear appropriate personal protective equipment, and the equipment is isolated from power sources to prevent accidents.

After the repair is completed, a comprehensive test of the equipment is carried out. This includes running sample production processes to verify that the fault has been completely eliminated and that the equipment's performance meets the required standards. The repair process and results are thoroughly recorded in the equipment maintenance records for future reference and to track the equipment's maintenance history.

2. Equipment Calibration Standards

2.1 Compliance with International and National Standards

Our equipment calibration work strictly adheres to international standards such as ISO/IEC 17025 (General Requirements for the Competence of Testing and Calibration Laboratories). This standard ensures that our calibration processes are carried out with the highest level of accuracy and reliability. We also comply with national standards relevant to the FPC, PCB, and rigid - flex board industries, ensuring that our products and services meet the regulatory requirements of different regions. By following these standards, we establish a solid foundation for the traceability of calibration results.

We have established a calibration traceability system. All calibrated measuring instruments and equipment can be traced back to national or international measurement standards through a chain of calibrations. This traceability ensures that the accuracy of our equipment calibration can be verified and compared with recognized standards, providing confidence in the quality of our products and services.

2.2 Calibration Parameters and Tolerances

For different types of equipment in the FPC, PCB, and rigid - flex board manufacturing, we have defined detailed calibration parameter lists. In an FPC etching machine, calibration parameters may include the etching rate, the uniformity of the etching process, and the dimensional accuracy of the etched patterns. In a PCB drilling machine, parameters such as drilling position accuracy, hole diameter tolerance, and the perpendicularity of the drilled holes are crucial.

Strict calibration tolerances are set based on the equipment's technical specifications and the requirements of the production process. For example, in the production of high - density FPC, the tolerance for the width of conductive lines may be set within a very narrow range, such as ±0.05 mm. If the calibration results exceed these tolerances, the equipment is adjusted or repaired immediately until it meets the specified requirements. This ensures that the final products meet the high - quality standards expected by our customers.

2.3 Calibration Cycle and Documentation

The calibration cycle of equipment is determined based on factors such as equipment usage frequency, working environment, and stability. Equipment that is used frequently or operates in harsh environments, such as FPC manufacturing equipment in a high - humidity production area, may require more frequent calibration, typically once a month or once a quarter. General - purpose equipment with a relatively stable working environment may have a longer calibration cycle, such as once every six months or once a year.

Complete calibration documentation is maintained. This includes calibration certificates issued by qualified calibration institutions or our internal calibration laboratory, which meets the relevant standards. Calibration records detail the calibration process, including the values measured before and after calibration, any adjustments made to the equipment, and the environmental conditions during calibration. Calibration reports summarize the overall results and provide an assessment of whether the equipment meets the calibration requirements. These documents are essential for tracking the calibration history of equipment and demonstrating compliance with quality management systems.
