Customers who have high requirements for silver paste baking after IC solidification need to use a high-precision vacuum hot air circulation dust-free nitrogen oven (oven/drying oven), which is also suitable for LCD IC packaging, LCD, In the manufacturing processes of transistors, optical materials, sensors, diodes, quartz crystal oscillators, hybrid integrated circuit boards, etc., a dust-free and oxygen free oven with hot air circulation can help improve product quality and meet the drying requirements of electronics, medical and health, instrumentation, factories, universities, scientific research and other departments for non oxidation, dust-free and uniform temperature.

Vacuum hot air circulation is a system of hot air circulation devices configured in a vacuum chamber to inject inert gases such as CO2 and N2, rapidly remove oxygen or cool down, form a low oxygen or anaerobic environment, and use the circulation system to make the temperature uniform.

The production process of the vacuum hot air circulation drying oven requires very precise operations, otherwise it will affect the vacuum degree and oxygen concentration. Therefore, when manufacturing the vacuum hot air circulation dust-free nitrogen oven, KeChang will equip an oxygen concentration meter to monitor the oxygen concentration content, the vacuum degree will be monitored by a vacuum gauge, and the temperature will be monitored at various points above 6 o'clock

The vacuum hot air circulation dust-free nitrogen oven adopts a closed and self circulating air inside the box, which is repeatedly filtered by a high temperature resistant and efficient air filter (Class 1000 or Class 100) to keep the working chamber of the oven in a dust-free state.

The working room of the vacuum hot air circulation dust-free nitrogen oven is made of stainless steel structure and reinforced with channel steel.

The temperature inside the working room of the vacuum hot air circulation dust-free nitrogen drying oven is automatically controlled by a touch screen temperature controller and can be connected to the customer's MES system through communication. It has automatic constant temperature and time control devices, vacuum degree adjustment functions, and is equipped with control functions such as automatic power outage and alarm circuit for overheating, oxygen concentration exceeding the standard alarm, etc. It is safe to use.

Precautions for making a vacuum hot air circulation dust-free nitrogen oven

a. Full week argon welding, high temperature resistant silicone gel rupture, SUS304 # stainless steel electric heating production device, to prevent dust generated by the machine itself;

b. High temperature resistance, under the premise of achieving a cleanliness level of Class 1000 in the workplace, the laboratory can effectively filter fine dust to achieve a cleanliness level of Class 100; Stacked in combination, reducing the area occupied by the site and achieving high efficiency.

c. All types of vacuum joint interfaces must be sealed completely, otherwise it will affect the vacuum degree

The vacuum hot air circulation dust-free nitrogen oven can be used for drying, heat treatment, aging, and other high-temperature tests of non-volatile and non flammable and non explosive materials.

Vacuum hot air circulation dust-free nitrogen oven maintenance method:

1. Clean the surface and interior dust to keep the machine clean and hygienic.

Check if the current on the ammeter is the same as normal. If there is any abnormality, notify the maintenance worker for inspection.

3. If there is a sudden power outage, the heating switch should be turned off to prevent automatic startup when power is restored.

5. Check if the fan is running normally and if there are any abnormal sounds. If there are any, immediately shut down the machine and notify the maintenance worker for inspection.

Check if the ventilation opening is blocked and clean the accumulated dust.

Check if the heating tube is damaged and if the circuit is aging.

Protection measures for vacuum hot air circulation dust-free nitrogen oven: The main control table controls the temperature throughout the entire process and controls the temperature inside the working room according to the pre-set program. If the temperature control system malfunctions and causes the working room temperature to continue to rise, when the working room temperature rises to level 2 mechanical protection, leakage protection, phase sequence protection, phase loss protection, overload protection, etc.
