China Vacuum Soldering Devices and Processing Ovens RS220
Function Introduction:
1. TORCH promotes a new Vacuum Reflow Oven in RS series which is the third generation of its small Vacuum Reflow Oven (eutectic furnace). It especially designed for the fields in small batch production, R&D and functional materials test, etc.
2. Industry application: RS series vacuum reflow soldering machine is the ideal choice for R&D, process research and development, low to high capacity production, and is the best choice for high-end R&D and production in military enterprises, research institutes, universities, aerospace and other fields.
3. Application: Mainly used for defect-free soldering of chips and substrates, tube shell and cover plate,and perfect solderless soldering, such as IGBT package, solder paste process, laser diode package process, optical communication device soldering, mixing Integrated circuit package, tube shell and cover plate package, MEMS and vacuum package.
4. Vacuum reflow has become an essential equipment for high-end manufacturing of military and industrial enterprises, aviation and aerospace in developed countries such as Europe and the United States, and has been widely used in chip packaging and electronic soldering.
Features
1. It can realize welding under vacuum, nitrogen and reducing atmosphere. The 2-way process atmosphere system nitrogen and formic acid, nitrogen and formic acid are controlled by MFC mass flow meter, which precisely controls the input of process gas to ensure the consistency of each welding process.
2. Temperature control system independently developed by ourself TORCH, temperature control accuracy
±1 °C; 2 flexible (patented technology) temperature sensor in the device cavity, real-time testing the
temperature of heating plate surface and fixture surface or internal, surface of the device, provides temperature feedback for components soldering, and the number of temperature sensors can be increased according to
customer needs.
3. Use graphite material as heating platform to ensure temperature uniformity within the welding area ≤±2%.
4. Equipped with a mechanical vacuum pump, the vacuum can be up to 10Pa.
5. The upper cover of the cavity is equipped with an observation window, which can observe
the internal device changes in the cavity in real time.
6. Through the patented water cooling technology, to achieve rapid cooling and cooling in the
atmosphere, vacuum environment, the industry's fastest cooling effect.
7. The self-developed temperature control software, up to the industry's 40-stage
programmable temperature control system, can set the most perfect process curve.
8. Closed cavity structure ensures long-term reliability. When the upper cover is closed during use, the device will not be displaced, avoid device vibration affecting the quality of the weld.
9. The unique water-cooling technology can ensure that the cavity is not overheated during welding, and at the same time. At the same time, the cooling of the heating plate is achieved during cooling, thereby improving the cooling efficiency.
10. TORCH technology patented technology temperature control system, can ensure the consistency of the welding process, the temperature curve can be realistically repeated in the software system, through the coincidence of the process curve can determine the process consistency of the same process of the same product.
11. Set the process curve by yourself and monitor the set process curve in real time. The process curve is set according to the process requirements (up to 6 sets of PID settings), the process steps are not limited; can be stored, modified, recalled, etc., in the process curve software. the process curve during welding is displayed in real time and automatically saved, which is convenient for the process traceability; the software has its own process curve analysis function to analyze the heating, constant temperature and cooling; The unique welding curve repeating display technology of the same process can prove the consistency of each sintering process by the coincidence of the process curve, ensuring that the device process of each soldering is consistent.
12. The software has anti-error interlocking, over-temperature, over-pressure, time-out alarm and other protection functions. When the hardware of the device fails or the software is set incorrectly, the software automatically prompts and alarms to determine whether the process continues.
