Segmented Heating Platen for Uniform Substrate Sticking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing press working methods for sticking substrates and support plates using an adhesive layer face challenges in achieving uniform pressure distribution, leading to non-uniform adhesive layer thickness and sticking issues, especially as the size of the substrate increases, causing difficulties in maintaining uniform contact and bonding.
Innovation Solution
A sticking apparatus and method that utilize a pair of plate members sandwiching the laminate, with supporting members arranged in a pattern of dots or lines at regular intervals to distribute pressure uniformly, preventing local concentration and ensuring consistent contact and bonding across the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the size of the substrate increases, then the pressing force by the heating platen must be increased to uniformly stick the substrate and support, but the heating platens themselves are bent by the pressing force, making it difficult to uniformly apply pressure
Solution Approach 1:
The heating platen is divided into multiple independent heating units arranged in an array. Each heating unit can independently apply pressure and heat to the substrate, allowing the system to handle larger substrates without requiring a single large, rigid platen. This segmentation prevents bending while maintaining uniform pressure distribution across the entire substrate surface.
Solution Approach 2:
The system changes the physical parameters of the heating platen by using multiple smaller heating units with adjustable pressure application. Each unit can be independently controlled to maintain optimal pressure and temperature, allowing the system to adapt to larger substrate sizes while maintaining manufacturing precision.
2Reliability
If the pressing force is increased to uniformly stick larger substrates, then the sticking quality improves, but the heating platen bends and cannot uniformly apply pressure
Solution Approach 1:
The heating platen is segmented into multiple independent heating units that can be arranged in various patterns (linear, grid, circular). Each unit independently applies pressing force to its local region, ensuring uniform pressure distribution across the entire substrate without causing bending of a single large platen structure.
Solution Approach 2:
The system transitions from a single-plane pressure application to a distributed multi-point pressure application. By arranging heating units in two-dimensional arrays (linear, grid, or circular patterns), the system applies pressure from multiple dimensions simultaneously, maintaining platen flatness while achieving reliable sticking quality.
3Device complexity
If a single heating platen is used to press the substrate, then the device structure is simple, but it becomes difficult to uniformly apply pressure across large substrate surfaces
Solution Approach 1:
The heating platen is segmented into multiple independent heating units that can be arranged in linear arrays, grid patterns, or circular configurations. Each unit is a simple, standardized component that can be independently manufactured and positioned, maintaining overall system simplicity while achieving uniform pressure distribution across large substrate surfaces through coordinated multi-point contact.

AI summary
A sticking apparatus including a pair of plate members sandwiching a laminate between the pair of plate members, and supporting members supporting the plate members. The supporting members supporting at least one of the plate members are located in a form of multiple dots or lines adjacent to each other at regular intervals on the plate member.
