Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual handling of heavy-duty probe cards, weighing between 25 kg to 40 kg, is burdensome and increases replacement time, leading to reduced productivity and risk of damage due to the need for manual carrying and separate workspaces, which hampers efficient semiconductor device inspection processes.
Innovation Solution
A high-duty probe card transfer and loading device that autonomously moves along a set driving route, equipped with a loading arm assembly and gripper unit, allowing unmanned transfer and loading of heavy-duty probe cards, minimizing workspace requirements and ensuring stable and timely supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of heavy-duty probe cards is performed, then the probe card can be replaced, but the replacement time increases and productivity decreases
Solution Approach 1:
The system enables automated self-service probe card replacement through the robotic arm assembly that autonomously picks up probe cards from storage, transports them to inspection devices, and performs replacement operations without human intervention, thereby reducing replacement time and increasing productivity
Solution Approach 2:
A robotic arm assembly acts as an intermediary between the probe card storage unit and inspection devices, automatically handling the transport and replacement of heavy-duty probe cards, which eliminates manual handling delays and improves overall system efficiency
2Reliability
If manual handling of heavy-duty probe cards is performed, then the probe card can be replaced, but the risk of damage or breakage increases
Solution Approach 1:
The automated robotic system performs probe card handling operations with precise control and consistent force application, eliminating human error and accidental impacts that could cause damage to expensive heavy-duty probe cards during replacement operations
Solution Approach 2:
The robotic arm assembly serves as a controlled intermediary that gently grasps and manipulates probe cards using specialized end effectors, providing stable and damage-free handling compared to manual operations where workers may inadvertently impact the cards during strenuous carrying
3Ease of operation
If separate work space is secured for each inspection device, then probe card replacement can be performed, but the workspace requirement increases
Solution Approach 1:
A single centralized probe card storage unit and robotic arm assembly serve multiple inspection devices simultaneously, eliminating the need for separate workspaces at each device location. The robotic system can service any inspection device in the array using the same hardware resources, thereby reducing overall workspace requirements while maintaining full replacement capability
Solution Approach 2:
The system merges the probe card storage, retrieval, transport, and replacement functions into a single integrated automated workstation that serves multiple inspection devices. This consolidation eliminates the need for separate manual workspaces at each device, reducing total space requirements while maintaining operational ease through automation
