Firstly, timely cleaning is essential. For reflow oven fixtures, it is generally recommended to clean them once a week after use, and also clean them once when taken offline to prevent excessive flux residue on the edges of the reflow oven fixtures due to prolonged use, which can make cleaning difficult and affect fixture performance. When cleaning multiple types of fixtures, they should be cleaned separately in batches.
Secondly, attention should be paid to the cleaning method. In addition to timely cleaning, the cleaning method for reflow oven fixtures is crucial. Based on years of experience, the most effective method is to place the fixtures in an ultrasonic cleaning machine for 45-60 minutes with a cleaning frequency of no less than 40KHZ. This method ensures thorough cleaning, and the cleaning records should be recorded in the fixture maintenance log for future reference.
Thirdly, proper classification management should be implemented. After cleaning, the fixtures should be inspected for any faults or defects. Any problematic fixtures should be promptly repaired and marked accordingly. Fixtures not in use should be properly classified and stored in a dry and clean environment. Both maintenance and issuance should follow the fixture usage standards to ensure compliance. This summarizes the complete content of the maintenance method for FPC SMT fixtures.
