SANYOSEIKO.CO., LTD began operations in 1963 and launched the “SMT Scope” in 1999. The company holds multiple patents, including technologies for high-temperature observation and solder paste wettability evaluation. In recent years, SANYOSEIKO has specialized in supplying a variety of gas environment heating systems tailored to customer requirements.

High temperature observation equipment SMT Scope

The high-temperature SMT Scope enables real-time observation of material behavior from room temperature up to 900 °C.

Key Features

Precise and repeatable temperature control
Support for various heating atmospheres
Stable high-magnification observation
Built-in image analysis and video editing tools
Wettability testing compliant with JIS standards

In addition to atmospheric and nitrogen heating, the system allows for oxygen concentration control within a nitrogen atmosphere. It also supports handling of formic acid, hydrogen, forming gas, and high vacuum conditions, along with dew point and oxygen level adjustments.
Optical magnification ranges from 0.078× to 20×, enabling clear observation of fine solder paste powders. Sample fumes and vaporized organics are removed by flowing atmospheric gas through the chamber, minimizing image distortion and maintaining high image quality.
Recorded videos can be quickly edited using built-in software. Measurement tools allow users to analyze length, angle, and area directly from still images captured during playback.
