Screen Printing Component Verification via ID Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In screen printing for electronic components, the diversity of printing conditions due to substrate type, material, and printing pitch leads to inconsistent squeegee usage, often resulting in degraded printing quality as the suitability of the squeegee with the substrate and mask is not verified.
Innovation Solution
A system and method that utilize identification marks on printing components (mask, squeegee, and paste) to verify their compatibility through component information matching with pre-allocated data, ensuring correct setup and informing operators of any discrepancies.

Engineering Contradiction Analysis
1Reliability
If verification is performed only on substrate and mask, then verification process is simple, but printing quality cannot be guaranteed when using substrates with high printing difficulty
Solution Approach 1:
The verification system is extended to handle multiple printing components (substrate, mask, and squeegee) using a unified verification approach. The same verification unit that previously only verified substrate-mask combinations now also verifies squeegee suitability, making the verification system multi-functional without requiring separate verification mechanisms for each component.
Solution Approach 2:
Suitability information for the squeegee is pre-stored in the verification unit, allowing the system to verify squeegee compatibility before actual printing operations begin. This preliminary verification ensures that only suitable squeegees are used with specific substrate-mask combinations, preventing printing quality issues before they occur.
2Adaptability or versatility
If multiple types of squeegees are prepared to match diverse substrate types, then printing conditions can be optimized for different substrates, but the complexity of component management increases
Solution Approach 1:
The verification unit provides immediate feedback to the operator about whether the selected squeegee is suitable for the current substrate-mask combination. This feedback mechanism guides operators in selecting the correct squeegee type, reducing the complexity of managing multiple squeegee varieties while maintaining optimal printing conditions for different substrates.
Solution Approach 2:
The suitability information stored in the verification unit acts as an intermediary between the diverse squeegee inventory and the operator's selection process. Instead of requiring operators to directly manage and select from multiple squeegee types based on complex criteria, the system provides pre-processed suitability information that simplifies the selection process.

AI summary
A method of determining whether printing components suitable for a type of a substrate are correctly set in a screen printing device that makes a mask provided with a pattern hole abut on the substrate, supplies paste onto the mask, and slides a squeegee to thereby print the paste on the substrate through the pattern hole, includes reading identification marks attached to respective printing components, verifying pieces of component information corresponding to the read identification marks using pieces of component information allocated to the substrate in advance in production data, and informing purport when a printing component having discordant component information is present in the verification. The printing components include at least a mask, a squeegee, and paste.
