MS Series Vacuum Welding Furnaces - MS440 / MS440T

Feature Introduction

MS Series Vacuum Welding Furnaces, professional industrial-grade vacuum welding furnaces.

Why opt for a vacuum welding furnace? The mainstream welding techniques in the industry currently use tools or equipment like soldering irons, wave soldering, and reflow soldering. Later, nitrogen protection was added, upgrading to nitrogen-free reflow soldering machines. However, for high-demand welding fields such as material testing, chip packaging, electrical equipment, automotive products, train control, aerospace, and aviation systems, which require high reliability in circuit welding, it is essential to eliminate or reduce voids and oxidation in welding materials. To effectively lower void rates and minimize oxidation on pads or component leads, a vacuum welding furnace is the ideal choice. To achieve high-quality welding, a vacuum welding furnace must be used. This is a new process innovation by SMT welding experts in countries like Germany, Japan, and the United States.

Industry Applications: The MS series vacuum welding furnaces are an ideal choice for R&D, process development, and production with capacities ranging from low to high. They are the preferred option for high-end R&D and production across various enterprises, research institutions, universities, and aerospace fields.

Application Fields: Primarily used for defect-free welding and precise solder paste-free welding in applications such as IGBT packaging, solder paste processes, laser diode packaging processes, hybrid integrated circuit packaging, can cover packaging, MEMS, and vacuum packaging.

Vacuum welding furnaces have now become an essential piece of equipment for various enterprises, as well as for high-end manufacturing in industries such as aviation and aerospace, in developed countries like Europe and the United States. They are also widely used in fields such as chip packaging and electronic welding.
