Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semiconductor component testing systems lack flexibility and efficiency in handling and testing singulated electronic components.
Innovation Solution
An automated test system with a handler and carrier station unit that allows simultaneous loading and unloading of electronic components while testing is performed, utilizing handler pickers and spinner pickers to manage multiple carriers and processing stations, enabling parallel operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single carrier is used for testing electronic components, then the testing process is simple, but the productivity is low due to sequential processing
Solution Approach 1:
The system divides the testing workload into multiple carriers, each holding a subset of electronic components. This segmentation allows parallel processing of components across different carriers, increasing throughput while maintaining manageable complexity through modular carrier design
Solution Approach 2:
Multiple carriers are pre-loaded with electronic components before the testing sequence begins. This preliminary preparation enables the testing system to immediately process multiple components in parallel without delays, thereby increasing productivity from the start
2Loss of time
If handler pickers load and unload carriers sequentially, then the handling process is simple, but the downtime increases
Solution Approach 1:
While one carrier is being tested, handler pickers simultaneously load a new carrier and unload the previous one. This preliminary action of preparing the next carrier during the current carrier's testing eliminates downtime and creates continuous processing flow
Solution Approach 2:
The system maintains continuous useful action by overlapping carrier loading/unloading operations with the testing process. Multiple handler pickers work in parallel to ensure that carrier exchange operations do not interrupt the testing timeline, eliminating idle downtime
3Adaptability or versatility
If only one processing station is used, then the system is simple, but the adaptability is limited
Solution Approach 1:
Multiple processing stations are configured to handle different types of electronic components or perform different processing operations. Each station can be universally applied to various component types through standardized interfaces, providing flexibility without requiring completely different systems for each component type

AI summary
An automated test system for testing singulated electronic components comprises a handler, comprising a plurality of handler pickers and/or spinner pickers, the handler pickers and/or spinner pickers being adapted to each pickup one electronic component, at least one processing station for processing one of the electronic components, a first carrier, a second carrier, and a test unit, for testing singulated electronic components located on a carrier. When the second plurality of electronic components on the second carrier are tested in the test unit while the second plurality of electronic components rest on the second carrier, simultaneously the first carrier is loaded with the first plurality of electronic components by the plurality of handler pickers and/or spinner pickers and/or unloaded from the first plurality of electronic components by the plurality of handler pickers and/or spinner pickers.
