Abstract
Innovation on die attach curing process on semiconductor industry play a big role to have a robust process eliminating unwanted gross unit rejection. Resolving failures and hardware breakdowns on the exhaust system of oven curing process are the focus of this paper. Discoloration and contamination due to outgas and fumes that cannot exit the oven chamber are the effects of a failed exhaust system. Addressing the said phenomenon showing simulations, trial runs will be discussed on this paper. Promoting an innovative approach that includes real time monitoring of the system performance, and detection of its failure to prevent continuous operation with failed exhaust system are performed to have an appropriate resolution.
