Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for releasing molded panels from glass carriers in panel-level packaging processes are inefficient due to the fragility of glass, limitations in carrier size, and susceptibility to electrostatic discharge, leading to significant failures and damage.
Innovation Solution
An automation line that uses a release workstation with a carrier-engagement arrangement capable of heating the first carrier to a release temperature, allowing for controlled separation of the molded panel without flipping, and transferring it to a second carrier while minimizing stress and electrostatic discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass carrier is used with UV release tape for releasing molded panel, then release function is achieved, but carrier becomes fragile and expensive, limiting carrier size and requiring manual handling
Solution Approach 1:
The patent replaces expensive, fragile glass carriers with disposable steel alloy carriers that are robust and can be automatically handled. The carriers are designed for single-use in the release process, eliminating the need for expensive, reusable glass carriers while enabling automated processing.
Solution Approach 2:
The patent replaces the UV light-based release mechanism with a thermal release mechanism using heat-resistant steel alloy carriers with thermal release adhesive. This substitution eliminates the need for UV transparency and enables automated mechanical handling instead of delicate manual operations.
2Reliability
If glass carrier with UV release tape is used, then molded panel can be released, but electrostatic discharge occurs during manual separation, causing significant failures
Solution Approach 1:
The disposable steel alloy carrier system eliminates the need for manual handling and separation operations that generate electrostatic discharge. The automated process using robust carriers prevents static buildup that occurs during delicate manual manipulation of glass carriers and UV release tape.
Solution Approach 2:
The patent replaces manual mechanical separation operations with an automated thermal release process. The heat-induced adhesive failure occurs automatically without manual intervention, eliminating the electrostatic discharge problem associated with manual peeling and separation of glass carriers.
3Reliability
If glass carrier is used, then release process can be performed, but carrier size is limited due to fragility, restricting large panel manufacturing
Solution Approach 1:
The robust disposable steel alloy carriers can be manufactured in large sizes without the fragility constraints of glass. This enables the processing of large-area molded panels while maintaining reliability in the release process through automated handling.
Solution Approach 2:
The replacement of glass carriers with steel alloy carriers and UV release tape with thermal release adhesive enables automated mechanical handling of large carriers. The robust material properties allow for larger carrier dimensions while maintaining structural integrity during automated processing operations.
4Reliability
If manual handling is used for glass carrier separation, then release can be performed, but process is time-consuming and prone to errors
Solution Approach 1:
The patent replaces manual handling operations with an automated thermal release system. The heated carrier automatically induces adhesive failure, and automated mechanisms perform the separation and transfer operations, dramatically increasing processing speed while eliminating human error and electrostatic discharge issues.
