Recently demand for large-capacity aluminum heat sinks has been increased as market for high power electricity expands and high-performance electronic products develop. While the brazed heat sinks are in particular preferred, it is almost impossible to manufacture them with an atmospheric continuous furnace due to insufficient heating rate and various thickness of the parent metals. Therefore, a new index batch furnace is developed and the process variables are optimized. Then, brazing
