Reflow Preparation Timing Control in Mount Substrate Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mount substrate manufacturing lines, the lengthy preparation processes for reflow apparatuses lead to decreased production efficiency as other apparatuses wait for completion, causing idle time during temperature and atmosphere adjustments.
Innovation Solution
A management apparatus connected through a network to the manufacturing line instructs upstream apparatuses to start production based on data related to the preparation time needed by the reflow apparatus, allowing auxiliary operations to be performed during this period to minimize waiting time.

Engineering Contradiction Analysis
1Reliability
If the reflow apparatus performs preparation processes (temperature and atmosphere adjustment) before production, then the reflow apparatus can operate properly, but other apparatuses must wait and production efficiency decreases
Solution Approach 1:
The management apparatus calculates the preparation time required by the reflow apparatus in advance and instructs upstream apparatuses to start production earlier, so that substrate processing is completed before the reflow apparatus needs to begin its preparation process. This preliminary coordination eliminates idle waiting time while ensuring the reflow apparatus is ready when needed.
Solution Approach 2:
The management apparatus receives data about the reflow apparatus's preparation time requirements and uses this feedback to dynamically adjust the production scheduling of upstream apparatuses. This closed-loop control ensures optimal coordination between apparatus preparation and production flow.
2Stability of the object's composition
If upstream apparatuses wait for reflow apparatus preparation to complete before starting production, then production timing can be synchronized, but idle time increases and productivity decreases
Solution Approach 1:
The system performs preliminary calculation of preparation time and schedules upstream apparatuses to start production in advance, maintaining timing synchronization without causing idle waiting. The management apparatus determines the optimal start time for upstream apparatuses based on the reflow apparatus's preparation requirements.
Solution Approach 2:
The production scheduling is made dynamic by continuously adjusting the start times of upstream apparatuses based on real-time data about reflow apparatus preparation requirements. This dynamic scheduling eliminates fixed waiting periods while maintaining proper timing coordination.

AI summary
A management apparatus is connected to a mount substrate manufacturing line including a print apparatus, a component mounting apparatus, and a reflow apparatus, through a network. The management apparatus instructs at least one of apparatuses that are at a more upstream side than a reflow apparatus in a mount substrate manufacturing line to start production of the mount substrate, based on first data relating to the period of time necessary to complete preparation for the performing of a process by the reflow apparatus.
