Abstract
A monitor, and method, for monitoring temperatures at various specific times and locations in a test or manufacturing process, and for comparing those temperatures with reference profiles of optimum temperatures. Both the monitor and the method are especially well suited for checking the temperatures of various zones of reflow ovens used in mass soldering the connections of electronic components on circuit boards. The monitor is designed to distinguish clearly among respective temperatures at several points on tops and bottoms of circuit boards.
