1. Maximizing Tray Space Utilization: Customizing tray space based on customer product dimensions to achieve maximum utilization.
2. Hardware Adjustments for Increased UPH: Optimizing hardware components such as heating platforms and vacuum chambers to enhance production efficiency (UPH - Units Per Hour).

1. Upper layer (cover plate): Can be replaced and adjusted based on fixture requirements
2. Lower layer (heating layer): 

• Custom designed with 9 heating rods of 250W, divided into three groups, each group has 3 rods.
• Custom designed with 9 heating rods of 250W, divided into three groups, each group has 3 rods.
• Each group is equipped with a temperature-measuring thermocouple, positioned at the upper left, middle, and upper right respectively.

• Effectively improves the edge temperature of the platform.
• Temperature difference issue between the edge and the middle after long-term usage.
