Test Tray Insert Positioning Guide for Semiconductor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiconductor devices are prone to separation and damage during transfer due to abnormal mounting in existing test tray inserts, leading to equipment damage and reduced yield rates.
Innovation Solution
A unit for opening the insert of a test tray, featuring a positioning guide that supports the semiconductor device to guide it into a preset position on a support within the insert, preventing abnormal mounting and ensuring secure holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semiconductor devices are transferred into the accommodating space without positioning guidance, then the transfer process is simple and fast, but the devices may be abnormally mounted, separated, or damaged
Solution Approach 1:
The positioning guide unit acts as an intermediary component between the semiconductor device and the support. It temporarily supports the device during transfer and then guides it to the correct position on the support, preventing abnormal mounting without requiring complex external positioning systems.
Solution Approach 2:
The positioning guide unit is preliminarily positioned within the accommodating space before the semiconductor device is transferred. This preliminary positioning ensures that the guide unit is ready to immediately support and guide the device as it is placed, preventing separation and damage before they can occur.
2Reliability
If holding units are used to maintain semiconductor devices during circulation, then device separation is prevented, but the devices may still be abnormally mounted causing damage
Solution Approach 1:
The positioning guide unit serves as a mediator between the holding units and the support. While holding units maintain device stability during circulation, the positioning guide unit ensures proper positioning during the transfer operation, preventing abnormal mounting that could cause damage.
Solution Approach 2:
The positioning guide unit is preliminarily installed in the accommodating space to prepare for proper device positioning. This preliminary action ensures that even when holding units are in place, the device will be correctly positioned during transfer, preventing abnormal mounting damage.
3Ease of operation
If the insert structure is simplified without positioning guides, then manufacturing and operation are easier, but semiconductor devices are prone to separation and damage during transfer
Solution Approach 1:
The positioning guide unit is a simple intermediary component that can be easily integrated into the insert structure. It provides necessary positioning guidance during transfer operations without complicating the overall insert design or operation procedures.
Solution Approach 2:
The positioning guide unit is preliminarily positioned within the insert structure during manufacturing. This preliminary integration ensures that device transfer safety is improved without requiring complex operational procedures or additional operational complexity.
