Electronic packaging applications and processes

- Jan 03, 2019-

It is mainly used for special vacuum packaging machine equipment in the electronics industry. It can prevent oxidation and pollution of electronic products during production and storage, and can better protect the use of electronic products.

1. It adopts stainless steel tank body, which is non-corrosive and easy to clean.

2, PCB control system, stable, not easy to malfunction.

3, the seal is reliable and airtight, long life and high efficiency.

1. Vacuum: The vacuum chamber is closed, the vacuum pump works, the vacuum chamber starts to vacuum, the vacuum inside the packaging bag, the vacuum gauge pointer rises, reaches the rated vacuum (controlled by the time relay ISJ), the vacuum pump stops working, and the vacuum stops. While working under vacuum, the two-position three-way solenoid valve IDT works, heat seals the chamber vacuum, and the hot press holder remains in place.

2. Heat sealing: IDT is broken, the outside atmosphere enters the heat sealing chamber through the upper air inlet hole, and the pressure difference between the vacuum chamber and the heat sealing chamber is utilized, and the heat sealing chamber is inflated and expanded to be placed under the hot pressing frame. Move, press the bag mouth; at the same time heat seal the transformer work, start sealing; at the same time, the time relay 2SJ works, after a few seconds, the heat seal is over.

3, return air: 2/2-way solenoid valve 2DT pass, the atmosphere enters the vacuum chamber, the vacuum gauge pointer returns to zero, the hot press frame is reset by the return spring, and the vacuum chamber is opened.

4. Circulation: Move the above vacuum chamber to another vacuum chamber, that is, enter the next working process, and the left and right chambers work alternately, and the cycle is repeated.
