Resolving electronic paste particle agglomeration

Core issues addressed by dispersants in the electronics industry and their specific applications. Dispersants address several key issues in the electronics industry by optimizing material dispersibility, improving process stability, and product performance. Below are the core functions and typical application scenarios:

1、Preparation of electronic ceramic paste

Issues: Ceramic powders (such as aluminum oxide, zinc oxide, etc.) are prone to agglomeration due to their high specific surface area, resulting in uneven paste viscosity and poor flowability, which affects coating accuracy.

Solution:
Dispersants stabilize particle dispersions through electrostatic repulsion and steric hindrance effects, enhancing the solid content of the paste and leveling properties (such as zinc oxide varistor paste).

Mengurangi flokulasi sekunder selama pelapisan untuk memastikan keseragaman dan keandalan komponen elektronik (seperti varistor, kapasitor).

industri elektronik

Misalnya, pasta dan tinta konduktif

Issues: Partikel konduktif (seperti bubuk perak, grafit) rentan terhadap sedimentasi dalam pasta, yang mengakibatkan konduktivitas tidak stabil.

Solution:
Penyebar bubuk grafit memastikan distribusi seragam partikel grafit berskala nano, meningkatkan konduktivitas dan keseragaman pelapisan tinta konduktif.

Penyerap polimer (seperti asam poliakrilat) membentuk penghalang sterik untuk mencegah partikel logam menggumpal dan mengoptimalkan akurasi garis papan sirkuit cetak (PCB).
