How to maintain a balance between high conductivity and stability in platinum conductor paste

1. Introduction

With the development of modern technology, the requirements for conductive materials are becoming increasingly high, especially in application scenarios that require long-term stable operation and low resistance, such as flexible circuit boards, solar cells, LED lighting, etc. Platinum, as a precious metal, has excellent corrosion resistance and oxidation resistance, making it an ideal choice for making high-performance conductors. However, in practical applications, how to ensurePlatinum conductor pasteProviding excellent conductivity while maintaining good stability in complex environments is an important issue.

2. Factors affecting the conductivity and stability of platinum conductor paste

2.1 Material composition

• Platinum powder quality: The purity, particle size, and distribution of platinum powder directly affect the conductivity of the slurry and the density after sintering. High quality platinum powder can reduce contact resistance and improve overall conductivity efficiency.
• Organic carrier system: The selection of solvents, adhesives, and other additives determines the flowability, coating uniformity, and drying and curing characteristics of the slurry. Suitable organic carriers can help improve printing accuracy and adhesion.

2.2 Process Parameters

• Sintering temperature and time: Appropriate sintering conditions are crucial for forming a continuous and compact platinum layer. Excessive temperature may lead to excessive melting or evaporation loss of platinum particles, while insufficient temperature may not achieve the desired bonding effect.
• Environmental humidity and temperature control: Changes in environmental conditions during storage and use may cause changes in the properties of platinum conductor paste, thereby affecting its long-term stability.

2.3 Application Requirements

• Mechanical stress: When applied to flexible substrates such as flexible PCBs,Platinum conductor pasteIt needs to withstand repeated bending without easily breaking or peeling off.
• Chemical compatibility: Interactions with other materials such as insulation layers, soldering, etc. can also affect the performance of platinum conductor pastes.
