MDVES400 Vacuum Eutectic Reflow Soldering Oven System
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.
Product description
The design basis of the MDVES400 vacuum sintering furnace is vacuum and water cooling control, which can not only ensure the void rate, but also increase the cooling rate.
The standard gas of MDVES200 includes: nitrogen, nitrogen-hydrogen mixed gas (95%/5%) and formic acid. The customer selects the corresponding gas as the process gas according to his actual situation, and does not need to worry about the additional configuration. The PLC control system of the equipment can well monitor the operations of vacuum pumping, inflation, heating control, and water cooling to ensure the stability of the customer's process.
Features
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;
