Environmentally Friendly Ultrasonic Immersion Soldering Tin Solution Without Flux

Hangzhou Shengtu Technology Co., Ltd. is one of the leading manufacturers and suppliers of environmentally friendly ultrasonic immersion soldering tin solution without flux in China. Welcome to buy high quality customized products at low price from our factory. Contact us for more details.

Ultrasonic tinning requires no flux. Ultrasonic vibration enables solder to penetrate micro gaps. No microbubbles or pores form within the solder layer, creating a tight, dense joint between solder and base metal. This improves the metal's weldability and ductility. Workpieces only need 3–10 seconds of direct immersion in the tin bath for targeted tinning.

FUNSONIC specializes in high-power ultrasonic core components and complete application systems, covering R&D, manufacturing, sales and after-sales service. Drawing on extensive industry experience, we deliver custom solutions to resolve customers' technical challenges, supplying full-system solutions and reliable, high-performance products.

1. Cut production costs and boost manufacturing efficiency

a. Solves the long-standing challenge of welding aluminum. Replacing costly copper with aluminum in products delivers substantial material cost savings for manufacturers.

b. Eliminating flux streamlines the soldering workflow, lifting processing efficiency while cutting labour expenses.

2. Enables new material and new product development

a. It achieves reliable joints for traditionally hard-to-weld substrates including glass, ceramics, aluminium and other non-metals, supporting advances in new material research.

b. Ideal for solar cell glass, semiconductors and ceramic heating elements. The technology readily handles bi-material composite bonding (aluminium‑copper, copper‑glass, aluminium‑glass, aluminium‑ceramic), facilitating new product R&D.
