Main Festures Of  Vacuum Reflow Oven KD-V43

1.Void Less
Void reduction between the joining partner (<2%) to ensure better heat transfer (based on the device surface quality and the gas selection). If the void is less than 30%, the bonding strength increases.

2.Excellent temperature control
PLC and MFC architecture ensure consistency and precision temperature control, as well as reliable protection.
Water Cooling system : Cross-cooling tube and water cooling tank provide rapid cooling in high-temperature environments.

3.Very Short Soldering Times
The welding cycle time is short, about 10 minutes (380-450 °C soldering temperature, cooling temperature to 45°C, nitrogen filling, welding vacuum is below 5-10-1 Pa).

4.Variation in process gas
Standard : 100% nitrogen is pumped into the vacuum chamber.

Option: HCOOH, ArH2 Plasma process gas, N2 & H2 forming gas.

5. Good human-machine interface
Windows provides system status queries, debugging/setting, alarms, and user interfaces.

6. Advanced PLC and Safe System:
The PLC system prevents accidental leaks, such as hydrogen leakage.
Alarms for excessive and ultultra-highmperatures
Low pressure warning system for cooling water
Protective covers for HCOOH tanks to prevent accidental explosions
System for detecting leaks of hydrogen gas and formic acid
Automatic pressure relief system in case of overpressure
A hydraulic pallet prevents water from damaging circuits
Automatic hydrogen burning prevents hydrogen pollution.

1. What is reflow soldering machine?
Besides assembling PCBs, reflow equipment also provides soldering capabilities in both small and large assembly areas. Depending on your rework and assembly area, you can purchase smaller reflow ovens if you solder in a small PCB assembly area.
 
2.What are the components of reflow?
The reflow solder profile usually consists of four stages, namely preheating, thermal soak, reflow and cooling. During the preheating phase, heat is accumulated smoothly on the board and on the components. In order to prevent components from being damaged by too rapid temperature changes, a temperature gradient has to be observed.

3.What are the principles of reflow soldering?
Reflow soldering is based on the role of hot air flow on solder joints, colloidal flux in a fixed high temperature airflow under the physical reaction to achieve SMD welding, with the name"reflow soldering"given to a process in which high temperatures are achieved through gas circulation in the welder during welding.
