How to invest LCD TV Final Assembly factory
Volume Requirements
- Total estimated time to complete weekly- production volumes with proposed equipment set = 160 hours/per week (+/- 10%)
Notes:
- Available time is 80 hours (16hours x 5days)!
- Factory efficiency not optimum due to:
- Weekly Scheduling
- Bottle Neck is SM Lines (Top/Bottom)
- Occupation of Lines, High Volume PC’s
- For schedule improvements we propose:
- To add and reconfigure SMT lines, create dedicated HV PC & PC Monitor SM lines
- Increase inventory, make longer runs, increase weekly batches, warming up Factory
