Abstract | At Intel, SPC++ chart is the standard model being used to monitor the key process parameters and quality. I t has been existed for many years. However, recently it was facing the quality issue on the new generation of Desktop product across Intel factories . The issue appeared at B all Attach Operation where the quality of the connection of th e solder balls and the package of the product were not meeting customer requirement. From the problem solving methodology, few hypotheses were come out and being validated: The current SPC++ control charts for Ball attach process parameters are in sufficient to detect all the assignable causes which is unable to trigger the quality issue . The current control limits of the existing process parameters are not appropriate to address the customer requirement of the product. After experiments, the root cause is the c urrent SPC++ control charts for Ball attach process parameters are insufficient to detect all the assignable causes which is unable to trigger the quality issue. Therefore, the team d ecided to study which other factors are contributing to the product quality and came out with the proposal to ha ve new process parameter which is flux activation time at 150 – 190 0 C to be monitored. So, from that situation, the author of this thesis will study on the control chart, then construct and validate the control chart to reflect the Ball Attach Operation production issue. |
