Abstract
In a method and a corresponding apparatus for controlling and monitoring the vacuum brazing of power components and SMD components, in which the temperature of the process is controlled using an open thermocouple, which is arranged separate from the furnace heating and is integrated in a base plate serving as a heat buffer, the temperature of the process is monitored and measured directly at the point of contact between brazing material and component. The uniformity of the temperature distribution during the process is measured by means of a contactless optical measuring system.
Claims22
A method for controlling and monitoring a brazing process for the vacuum-brazing of power components and SMD components, the method comprising the step of controlling the temperature of the process by using an open thermocouple, which is arranged separate from the furnace heating, and is monitored and measured directly at the point of contact between brazing material and component.
An apparatus for carrying out a method for controlling and monitoring a brazing process for the vacuum-brazing of power components and SMD components, comprising a vacuum chamber, the temperature of which is controlled by means of a furnace heating, wherein the temperature measurement is controlled by way of an open thermocouple which is arranged separate from the furnace heating in the vacuum chamber and is integrated in a base plate, the base plate being directly connected to the substrate for the components.
