Probe Cleaning Sheet Structure to Prevent Probe Pin Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing probe cleaning sheets are ineffective at room temperature, in hot or low temperature environments, and cannot gently and efficiently clean the front ends of probe pins without causing damage, as they fail to remove foreign substances and often result in probe pin wear or inability to clean.
Innovation Solution
A probe cleaning sheet comprising a mold release layer, a cleaning layer with high and low density abrasive particles, a protective netting layer, and a substrate, where the cleaning layer is made of silicone with negative charge and lipophilic properties to attract and remove foreign materials, and the protective layer prevents overpressure damage to the probe pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning component made of acrylic resin or urethane resin is used to remove foreign substances from probe pin tips, then cleaning function is provided, but fragments form new foreign substances that adhere to probe pin tips or damage the tips causing excessive wear
Solution Approach 1:
The cleaning sheet uses a composite structure combining a polyurethane substrate with a polishing layer containing finer abrasive powder and a binder layer. This composite material design allows the polishing layer to effectively remove foreign substances without generating harmful fragments that would damage the probe pin tips.
Solution Approach 2:
The invention changes the material parameters by using a polyurethane substrate with good buffer performance instead of acrylic or urethane resin, and incorporates finer abrasive powder in the polishing layer to reduce fragment formation while maintaining cleaning effectiveness.
2Adaptability or versatility
If existing probe cleaning sheets are used in hot or low temperature environments, then cleaning function is provided, but they cannot be used at room temperature or in hot/low temperature environments effectively
Solution Approach 1:
The invention uses polyurethane as the substrate material which has good buffer performance and maintains its mechanical properties across a wide temperature range, enabling effective cleaning at room temperature, hot environments, and low temperature environments where existing cleaning sheets fail.
Solution Approach 2:
The cleaning sheet is designed to function effectively across multiple temperature conditions (room temperature, hot environments, and low temperature environments), making it a universal cleaning solution that replaces the need for different cleaning sheets for different temperature conditions.
3Reliability
If a polishing layer with finer abrasive powder is used to clean probe pins, then cleaning effectiveness is improved, but the structure becomes more complex requiring substrate, polishing layer, and binder layer
Solution Approach 1:
The cleaning sheet is divided into functional segments: a polyurethane substrate providing structural support and buffer performance, a polishing layer containing finer abrasive powder for effective cleaning, and a binder layer for attachment. This segmentation allows each layer to perform its specific function optimally.
Solution Approach 2:
The invention combines the substrate, polishing layer with finer abrasive powder, and binder layer into a single integrated cleaning sheet structure, simplifying the overall system while maintaining the necessary functional complexity for effective probe pin cleaning.
