Selective Flux Ultrasonic Coating System The Selective Flux Ultrasonic Coating System is an advanced, high-precision automated device designed specifically for the selective soldering process in electronics manufacturing. It replaces the traditional spray or foaming process used in wave soldering, as well as manual application methods. The core principle is to use ultrasonic energy to atomize liquid flux into extremely fine particles (forming a fine mist or aerosol). Then, [...]

Why do Wrinkles Occur During Film Coating? In the plastic film coating industry, meticulously formulated coatings and well-tuned equipment, only to produce a finished film riddled with orange peel patterns, is undoubtedly a major frustration. This issue is more than just a cosmetic issue—it directly impairs the product's optical performance, interferes with subsequent lamination or printing processes, and can even lead to customer returns. Orange peel patterns are [...]

The Era of Polyimide Separators Has Arrived Amid the rapid development of new energy technologies, research into high-performance battery materials is central to driving advancements in electric vehicles and energy storage systems. Polyimide (PI), with its exceptional high-temperature resistance, flame retardancy, and insulation properties, holds great potential in the battery separator field. PI films remain stable at temperatures exceeding 500°C and exhibit excellent electrolyte wettability, offering a new [...]

Preparation of the Ceramic Dielectric Layer The ceramic dielectric layer is the supporting framework of the AMB copper-clad laminate (CCL). Its quality directly impacts the thermal conductivity, mechanical strength, and reliability of the circuit board. The preparation process requires strict control of raw material purity and process parameters. The main steps are as follows: Raw Material Selection and Pretreatment Ceramic Powders: – Alumina (Al₂O₃): Purity ≥99.5%, low cost, [...]
