Problems solved by technology
The above process, the test board production process consumes manpower, time and materials; and there are also its insurmountable weaknesses: often these products (test boards) themselves are easy to age, after many such tests, their thermal conductivity, quality, The shape and even the color will change accordingly, and the result is that the test data is not reliable; in addition, the test is carried out intermittently, and it is difficult to detect the change of the heat treatment process parameters between two monitorings, which may lead to product batch quality problems; It is said that the existing monitoring is difficult to accurately measure the actual heat treatment process of a product in the heat treatment equipment in real time

Embodiment Construction
[0040] In order to facilitate the understanding of the present invention, this article describes the present invention by taking the reflow oven commonly used in the electronics industry as an object. The following briefly introduces the structure of common reflow ovens.
[0041] Referring to Fig. 1, this figure is a typical reflow furnace heat treatment module 1, and its process chamber 10 is provided with a heating device 3 and a convection device 4 above and below the flow path 20 of the workpiece 2; for heating.
[0042] Referring to Figure 2, as shown in the figure, a reflow soldering furnace is composed of several heat treatment modules, the process chambers of each heat treatment module are interconnected, and the chain 21 drives the workpiece to pass through the process chambers of each heat treatment module in turn, that is, the workpiece is completed heat treatment. In order to monitor the temperature of the process chamber, a temperature detection device 30 is ins...

The invention relates to a technical process of heat treatment, in particular to a real-time monitor method of heat treatment technical treatment, a preset technical method and the equipment. The invention is introduced with a standard test piece with stable thermodynamics parameters as the basic of reference; the situation of the heat treatment equipment is evaluated through real-time monitoring of the standard piece. The invention is of reliable in the monitor result, convenient in operation and saves the expense of making test sample in the prior art.
Description
Technical field [0001] The invention relates to a heat treatment process, in particular to a real-time monitoring method for heat treatment process equipment, a process setting method and a real-time control method and equipment. Background technique [0002] The rapid development of industry has been able to satisfy people's individual choices in various products. This tendency of personalized selection has also led to product diversification and rapid replacement. In this era of diversification, the speed and cost of launching new products have become the key factors for the success of an enterprise. Among them, the conversion and monitoring of production processes when updating products become particularly important. At present, the production process of many products in the industry requires specific heat treatment, such as: product glue coating and drying process, electronic product reflow soldering process, electronic product wave soldering process, quenching, freezing...
