2.Special material confirmation: Confirm materials that have previously experienced abnormalities before reflow oven production, and confirm materials in one batch;


3.First piece confirmation:

(1)Provide a brief understanding and testing of the first article, and review relevant first article records;

(2)Check if the previous problem points have reoccurred and if there has been any improvement in the hands;

(3)Confirm whether the previous reflow oven process and process need improvement.


4.Confirmation of Defective Product Analysis: Conduct a simple analysis of defective products, understand the main distribution and causes of defects, and strive to improve them as much as possible;


5.Information feedback:

(1)Feedback on SMT reflow oven production issues to the person in charge of the production technology, reminding attention to them;
