High precision vertical tube furnace

High precision vertical tube type high temperature furnace is mainly used in the drawing process of chip industry. According to the high uniformity of ± 2 ℃, it can ensure the high uniformity of connecting gold wire and silver wire inside the chip, so as to ensure the good conductivity. The heating wire is arranged unevenly, and the circulation of hot and cold air is used to ensure the temperature in the constant temperature zone. The accuracy is higher and more accurate.

High precision vertical tube furnace Performance characteristics:

1. Alumina polycrystal fiber curing furnace, good heat preservation performance

2. Intelligent program temperature control system, resistance wire heating
