The vacuum eutectic reflow furnace is a device that uses the principle of vacuum heating to provide a process environment for the alloy solder of electronic components.

Application:
IGBT modules, TR components, MCM, hybrid circuit packages, discrete device packages, sensor/MEMS packages (water-cooled), high-power device packages, optoelectronic device packages, air-tight packages (water-cooled), eutectic bump welding, etc.
Introduction:
1. This kind of reflow soldering is performed in a real vacuum environment;
2. It must be soldered with the help of low-activity flux;
3. A good operating experience can be achieved through professional software control and touch screen control;
4. With a programmable temperature control system, you can also set a better process curve;
5. The temperature setting of the machine adopts a touch-type lifting mode, which can directly pull the curve by hand, so that a process closer to the process curve of the welding material can be set;
6. Water cooling technology can achieve the fastest cooling effect in the industry;
7. Four groups of on-line temperature measurement functions can realize the accurate measurement of uniform temperature in the welding area;
8. Formic acid, nitrogen, etc. can be selected to meet the requirements of special welding processes;
9. The PLC control system of the equipment can well monitor the vacuum, inflatable body, heating control, and water cooling operations;
10. The top cover of the cranial cavity of the device is also equipped with an observation window, which is convenient for the staff to observe.
1. MDVES400 is a cost-effective product with a small footprint and complete functions, which can meet customer R&D and initial production use;
2. The standard configuration of formic acid, nitrogen and nitrogen-hydrogen gas can meet the gas demand of various products of customers, without the trouble of adding process gas pipeline for the follow-up;
3. Adopting water cooling control can increase the cooling rate, so that the production rate can be increased and the production can be maximized; 4. When the customer relates to the vacuum sealing of the tube shell, the water cooling design will highlight the advantages and avoid the air cooling caused by the tube sheet and The puncture problem of the tube shell.
