Customer reviews

Sarah · Quality Control Specialist in Electronics
The electronic-grade stearic acid (99.5% purity) is a game-changer for our PCB manufacturing. Its high purity ensures minimal contamination, which is critical for maintaining the integrity of our electronic components. The product's performance in flux and solder paste applications has been outstanding, and we highly recommend it for any high-precision electronic manufacturing needs.

Product Description

Product features:

Produced via multiple rounds of molecular distillation and ion exchange purification, this product has impurity levels far below the strict limits of the electronics manufacturing industry, with no detectable residual sulfur or heavy metals that could compromise semiconductor performance. Its ultra-fine particle size ensures uniform coverage on mold surfaces, reducing wear and improving production yield for high-precision electronic components.

Product application:

It is primarily used as a mold release agent in semiconductor chip packaging processes, reducing sticking between encapsulation materials and production molds and improving the yield of high-precision semiconductor components. It also acts as a lubricant in electronic assembly lines, improving the flowability of electronic materials and reducing equipment wear. It is also used as a surface treatment agent for PCBs to improve insulation performance and corrosion resistance. Target customers include semiconductor packaging facilities, PCB manufacturers and electronic component suppliers.

Frequently Asked Questions (FAQ)

Q:What are the main differences between industrial-grade stearic acid (85% purity) and electronic-grade stearic acid (99.5% purity)?
A:Industrial-grade stearic acid (85% purity) is cost-effective for general manufacturing, while electronic-grade (99.5% purity) undergoes rigorous purification for semiconductor/PCB applications, minimizing ionic impurities (<5ppm).
