Description

Temperature adjustment equipment of high temperature oven

The present invention belongs to the technical field of electronic packaging, and particularly refers to the technically providing a temperature adjustment device for a high-temperature oven. The gas flowing out of the processing chamber is cooled by the cooler in the gas reprocessing device, and the gas is heated by the heater. The gas in the gas reprocessing device is reused by the gas recovery device to return the gas to the processing chamber, which greatly improves the heating and cooling efficiency of the gas, and achieves the purpose of gas recovery and reuse, effectively reducing production costs.

In recent years, electronic technology has been changing with each passing day. Electronic products composed of integrated circuit components have become an indispensable tool in modern people's daily life. In the semiconductor packaging process, the cooling process and the heating process often play an important role, and it is often necessary to switch between the cooling process and the heating process. For example, cooling from high temperature to low temperature or cooling from high temperature to low temperature and then heating to high temperature, etc., the faster the cooling and/or heating rate, the higher the process efficiency. In the conventional cooling process, air-cooled or water-cooled coolers are often used directly in the processing chamber for gas cooling. However, the heat capacity of the cavity is too large to achieve rapid cooling effects. In addition, in the conventional In the heating process, the heater is often used directly in the processing chamber for gas heating. Also, because the heat capacity of the chamber is too large, the effect of rapid heating cannot be achieved. Therefore, in order to achieve the effect of rapid cooling and rapid heating, the conventional The cooling process often uses the direct discharge of high-temperature gas, and then the low-temperature gas is introduced to achieve the effect of rapid cooling. However, because the existing high-temperature gas must be evacuated, and then new low-temperature gas must be introduced from the outside, the existing gas cannot be effectively used, resulting in waste of gas costs. Under the above circumstances, if it is further desired to return the process temperature to the temperature level before cooling (or even reach a higher temperature level than before cooling), the low-temperature gas must be evacuated first, and then a new high temperature is introduced from the outside Gas also leads to waste of gas costs. In addition, during the heating process, part of the process chemicals will be diffused in the processing chamber due to volatilization or evaporation. When the process is cooled, the gaseous process chemicals floating in the processing chamber are condensed to form pollutants attached to it. The inner wall of the cavity increases the maintenance cost of the machine and reduces the production capacity. In addition, the oven used in the conventional semiconductor packaging process is heated by heat convection. This heating method requires a set of fans to be placed inside the oven to make the inside The heated gas produces convection. In order to increase the temperature quickly and the uniformity of the temperature rise, it is necessary to consider accelerating the flow of the heated gas. The vibration of the baked product caused by such gas disturbance poses an unpredictable risk for many semiconductor components. There is a need for improvement.

Therefore, in view of the above-mentioned problems of the conventional semiconductor packaging due to process switching, how to develop a temperature adjustment device that is more ideal and practical while taking into account economic benefits is actually the goal and direction for the relevant industry to actively research and develop breakthroughs.

In the conventional semiconductor package, the heat capacity of the cavity is too large to achieve the effect of rapid cooling and rapid heating when the process is switched. In order to improve the cooling and heating effect, the cooling process often uses direct discharge of high-temperature gas, and then enters the low-temperature Gas, resulting in a waste of gas cost. In order to make the temperature quickly reach the temperature level before cooling during the heating process, the low-temperature gas must be emptied first, and then new high-temperature gas is introduced from the outside, which also leads to a waste of gas cost. The oven used in the conventional semiconductor packaging process is heated by thermal convection. In order to increase the temperature quickly and the temperature uniformity during the temperature increase, it is necessary to consider accelerating the flow of the heating gas. The disturbance of the gas causes a lot of vibration to the baked product. For semiconductor components, there are risks that are difficult to guess, and there is a need for improvement.
