Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fragile flexible substrates with thicknesses of 0.2 mm to 3 mm are prone to breaking or deforming during handling and high-temperature processes due to thermal expansion and vibration, leading to reduced production efficiency and yield.
Innovation Solution
A vertical clamping substrate jig with a jig body, fixing structures, clamping members, and supporting members is used to securely hold and transfer fragile flexible substrates vertically, employing non-metallic materials with similar thermal expansion and conductivity to minimize deformation, and equipped with pressure sensors to monitor clamping force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional horizontal handling methods are used for fragile flexible substrates, then the handling process is simple, but the substrates are prone to breaking or deforming due to thermal expansion and vibration during transfer and high-temperature processes
Solution Approach 1:
The patent inverts the traditional horizontal handling approach by implementing vertical clamping and transfer. The substrate is clamped vertically between upper and lower clamping plates, and transferred in a vertical direction through the baking oven, completely reversing the conventional horizontal processing method to eliminate deformation and breaking issues
Solution Approach 2:
The handling device is segmented into multiple functional components: upper and lower clamping plates with clamping mechanisms, a transfer mechanism with vertical movement capability, and a positioning system. This segmentation allows each component to perform its specific function optimally while working together to solve the substrate handling problem
2Stability of the object's composition
If conventional clamping methods are used, then the clamping structure is simple, but the substrates deform under high temperature due to thermal expansion differences
Solution Approach 1:
The patent changes the clamping force parameters dynamically through adjustable screw mechanisms and elastic elements. The clamping force can be precisely controlled to match the substrate's thermal expansion characteristics during high-temperature processing, maintaining stable clamping without causing deformation
Solution Approach 2:
The clamping system uses composite structural design combining rigid clamping plates with elastic elements and adjustable mechanisms. This composite structure provides both the rigidity needed for stable clamping and the flexibility to adapt to thermal expansion, maintaining substrate shape stability under high temperature
3Reliability
If vertical clamping and transfer method is implemented, then substrate breaking and deformation are prevented, but the device structure and operation complexity increase
Solution Approach 1:
The vertical clamping system incorporates self-adjusting mechanisms including elastic elements that automatically adapt to substrate thickness variations, and screw mechanisms that self-lock to maintain clamping force. This reduces the need for complex manual adjustments and makes the system easier to operate while maintaining high reliability
