The Core

This essay focuses on the temperature variation law of the center of the target board soldering area at a certain position when the reflow oven starts working as the core discussion. Using the principle of heat conduction, Fourier's law to solve the problem of temperature values and temperature change laws in the center of the soldering area of the target circuit board at different locations under set conditions. As in the actual process, the temperature change in the center of the soldering area is limited to certain conditions, we can use the target planning, prediction methods, to build a model to solve the maximum problem. At the same time we need to consider the quality of the target circuit board, the use of neural networks, genetic algorithms to establish optimization models for target optimization, and ultimately the optimal furnace temperature curve.

Chemical Evidence

In a previous paper discussing the photographs of stellar spectra taken with the calcite prismatic camera, I showed that the variation of the position of maximum intensity, when we dealt with the various genera of stars, corresponded with the temperature change—including in that term the possible results of electrical energy —suggested by the Chemical Classification. 2. Object of the Present Research . Obviously the next test to apply to the temperature curve based upon the Chemical Classification was to compare, under similar conditions, the relative temperatures of those genera placed on the same temperature horizon but on the opposite sides of the curve, since the chemical evidence indicated that, while there are differences in the conditions of absorption in such genera, their temperatures are approximately the same.

Abstract Reflux welding is widely used in SMT (surface patch technology) During this production process, the quality of the product is essential to maintain the temperature and the furnace speed required by the process. The furnace temperature curve in the furnace is an important form of reaction welding process. In order to improve the process efficiency of the return furnace, the heating welding process model is established based on the Fourier heat conduction law,1 D heat conduction model and Newton cooling law and draws the furnace temperature curve model. Then, the upper boundary of the conveyor speed using the boundary analysis and multiple target planning, and further explore the research and optimization direction of subsequent process flow. At the same time, this paper examines and analyzes the modeling process and results, and effectively demonstrates the scientific nature and accuracy of the model. Finally, the paper analyzes the significance of the above model and research in chip processing.
