1. The name V3/V4/V5 is called according Vacuum, means professional industrial Vacuum reflow oven.
2. Why chose Vacuum reflow oven? Recently, the main welding tool is soldering iron, reflow oven, wave solder machine or other welding machine, and later update to Nitrogen reflow oven. But some welding, need high requirement of welding, like material testing, Chip packing, Power equipment, Automotive products, Train control, Plane system, aerospace system, which need avoid the Empty and oxidation of welding. Vacuum reflow oven is the unique choice to reduce empty and oxidation. Vacuum reflow oven can make sure high quality of welding. Vacuum welding is the new technology in Germany, Japan, USA.
3. Application of industry:  Research institutes, University, Aerospace, and it's the best choice for R&D, Process research.
4. Application of field: Suit for no defect welding and perfect no flux welding in Chip and PCB Board, cover and board, like IGBT package, solder paste process, laser diode package, IC package, MEMS and vacuum package.
5. Vacuum reflow oven is the necessary equipment in  Aerospace in USA, European, also get university application in Chip package, electronic welding.


Feature of the vacuum reflow oven:
1. Vacuum welding environment, can be up to 10-3mba (Molecular pump 10-6mba is optional)
2. Low active flux welding environment
3. Touch screen control and professional software, get perfect operation.
4.40 sections programmed temperature control system, can set perfect welding profile carve.
5. Temperature setting used touch control model, and can be pulled the carve by hand.
6. Unique water cool system, realize the fastest cooling.
7.4 temperature testing. Realize the measurement of temperature uniform in welding zone. Supply professional reference in process testing.
8. Formic acid, nitrogen or other Inert gas suit for special welding process.
9. Patent design in online real video system, can take video of every process and provide good reference for quality tracking, perfect data support in researching of welding and test in materials.
10. Highest temperature: 450 degree Celsius (higher temperature is optional), meet all soft welding needs.
