Silicone Member Antistatic Additive for Micro Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Silicone materials used in micro devices are prone to electrification, leading to dust and burr adhesion, which hinders sample observation and flow, and adding conducting materials to suppress electrification reduces transparency, making it unsuitable for optical checks.
Innovation Solution
Incorporating an ionic conductive agent into the silicone material at a specific concentration range (0.01 to 1 part by mass per 100 parts of silicone) to provide electrical conductivity while maintaining high light transmittance, thereby suppressing electrification and adhesion issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conducting material is added to silicone to suppress electrification, then electrification is suppressed, but light transmittance is reduced
Solution Approach 1:
The patent changes the chemical composition parameters by introducing ionic conductive agents (quaternary ammonium salts, phosphonium salts, or sulfonium salts) at specific concentration ranges (0.01-1 part by mass per 100 parts of silicone). This parameter optimization enables electrification suppression while maintaining light transmittance above 70%, resolving the contradiction between conductivity and transparency.
Solution Approach 2:
The patent creates a composite silicone material combining base silicone with ionic conductive agents. This composite approach allows the material to simultaneously achieve electrical conductivity for electrification suppression and optical transparency for micro device applications, unlike conventional conducting materials that compromise transparency.
2Reliability
If antistatic ingredient is attached to surface to suppress electrification, then electrification is suppressed, but dust and burr may adhere to holding part
Solution Approach 1:
The ionic conductive agent acts as an intermediary substance within the silicone matrix that provides electrification suppression without requiring surface attachment. This internal incorporation approach avoids the problem of surface-coating materials adhering to the holding part, as the conductivity is distributed throughout the bulk material.
Solution Approach 2:
By changing the physical state of the antistatic function from surface-coating to bulk-incorporated ionic conductive agent, the patent eliminates the adhesion problem while maintaining electrification suppression. The ionic conductive agent is integrated into the silicone matrix at controlled concentrations, preventing dust and burr accumulation.
3Reliability
If ionizer is used to eliminate static electricity, then antistatic effect is obtained temporarily, but effect is lost during hermetic baling and transport
Solution Approach 1:
The silicone material with incorporated ionic conductive agents provides self-service antistatic protection through its inherent electrical conductivity. Unlike external ionizers that require power and maintenance, the ionic conductive agent is permanently integrated into the material, ensuring continuous electrification suppression throughout the entire lifecycle including hermetic baling and transport.
Solution Approach 2:
The ionic conductive agent is preliminarily incorporated into the silicone material during manufacturing, providing permanent antistatic protection from the outset. This preliminary integration ensures that the antistatic effect is already established before the material enters service, eliminating the need for subsequent treatment or maintenance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents electrification and adhesion of dust and burrs, ensuring proper sample handling and observation while maintaining the transparency required for optical checks.
Implementation Method 1
a silicone material which has silicone and an ionic conductive agent, and the content of the ionic conductive agent is 0.01 part by mass or higher and 1 part by mass or lower with respect to 100 parts by mass of the silicone
Implementation Method 2
Because silicone is easy to be electrified, dust in the air, tiny burr during molding and so on are easily adsorbed
