To ensure optimal performance, the evaporation material must meet stringent quality standards:
1. High purity:
The purity is up to 99.9999% to minimize defects and contamination.
2. Stability:
The evaporating particles are not easily decomposed before evaporation; the crucible is stable and reliable during the evaporation process.
3. Melting point:
The selection is based on the deposition method and substrate compatibility.
4. Defects:
The material has few internal defects and pores, and evaporates evenly.
5. Uniform particle size:
It is essential for continuous evaporation and film formation.
Production and Quality Control
We employ advanced production technologies and stringent quality control measures to ensure the supply of high-quality evaporation materials.
1. Manufacturing process
High-purity raw materials are processed through smelting, refining, and vacuum sintering.
2. Quality Assurance
Purity analysis: Ensures that the material meets the required specifications.
Particle size testing: Verify performance consistency to ensure consistent performance.
Material assessment: Check melting point, density and other key factors.
