What is a vacuum reflow oven ? What are the categories ?

Vacuum reflow solder is refers to the vacuum eutectic oven, vacuum in vacuum environment for high quality welding products, in the welding process of zhongtong into reducing system (N2, formic acid, N2H2, H2), to protect the product and the solder is not oxidized, at the same time the product and solder oxide on the surface of the reaction, make weld surface quality improvement, reduced the rate of welding hollow.

1. Single-cavity vacuum reflow welding: this product is the most mature of Germany ATV and Beijing TORCH V series vacuum furnace.

2. Multi-layer vacuum reflow welding: Germany centrotherm and Beijing TORCH H series vacuum oven are the most famous ones.

Almost all IGBT plants have bought the German vacuum oven.

TORCH's H6 was also used in BYD's IGBT production plant in 2015.

3. On-line plate vacuum oven: this kind of vacuum oven is well done by TORCH comrade V8S V9S.

Frame product void rate can be achieved within 0%.

4. On-line hot air vacuum oven: this type of vacuum oven has been produced by SMT ETC HELLER BTU and other companies.

Foreign manufacturers are doing well, but prices are also high.

The TORCH also has a V8L V10L version.

5. True air phase reflow welding: the manufacturer of this vacuum oven is relatively few.

REHM IBL is mostly made by German companies.

Gas phase welding defects are also very obvious, the temperature can only reach 230-240 degrees, can not do gold and tin and other high temperature alloy products.
