Segmented Parallel Dispensing Layout for Semiconductor Conductor Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial printing operations, particularly in semiconductor production, face challenges in increasing productivity while maintaining low costs, as existing methods require complex and costly power drive systems to apply multiple parallel printed lines efficiently on substrates.
Innovation Solution
A device with a printing unit featuring multiple dispenser nozzles arranged along specific axes to create parallel printed lines, allowing for a single relative movement that generates multiple lines, with the option to control these lines to touch, overlap, or remain spaced, thereby increasing productivity without increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power drive means are configured to increase the speed of relative movement between printing unit and substrate, then productivity is improved, but device complexity and costs increase
Solution Approach 1:
The printing unit is segmented into multiple dispenser nozzles (first, second, third dispenser nozzles) arranged along a longitudinal axis parallel to the movement direction. Each nozzle independently deposits print medium to create separate printed lines, allowing parallel production of multiple lines without increasing the speed of the drive means, thus maintaining simplicity while improving productivity
2Productivity
If multiple dispenser nozzles are arranged transversely spaced apart to create parallel printed lines, then productivity is improved, but the time to apply all printed lines increases
Solution Approach 1:
The dispenser nozzles are arranged not only transversely spaced apart (perpendicular to movement direction) but also longitudinally spaced apart (parallel to movement direction) along a common axis. This three-dimensional arrangement allows printed lines to be deposited in parallel while maintaining optimal deposition rates, creating continuous or segmented lines as needed without extending the relative movement time
3Productivity
If the speed of relative movement is increased to reduce application time, then productivity is improved, but manufacturing precision deteriorates
Solution Approach 1:
The application process is segmented into multiple independent nozzle operations. Each dispenser nozzle operates at optimal deposition speed to maintain precision, while the overall productivity increases because multiple nozzles work simultaneously to create multiple printed lines in parallel, rather than requiring one nozzle to cover the entire distance at high speed
