Temperature Curve of Reflow Furnace Based on Newton’s Law of Cooling

Soldering in a reflow oven is an important and efficient technical means to produce integrated circuit boards. The key the quality of boards lies furnace temperature curve. In this paper, Newton’s law cooling used establish mechanism model each zone curve temperature, which can reduce number experiments actual production obtain better curve, thus improving efficiency. Finally, several concrete examples are given discuss solve some common problems industry.
