In this research, a warpage measurement system to simulate forced convective reflow is designed and developed. In order to design a system to simulate forced convective reflow, the system should be capable of heating a PWB at an average rate of 2 °C/second. This paper will present PWB heating rate results produced by modifying a laboratory oven to enable it to simulate forced convective reflow. The initial modification of the current forced convective reflow oven failed to achieve the desired PWB heating rate. Therefore, a computational fluid dynamics (CFD) analysis was carried out to determine which critical oven parameters could be modified to produce the desired PWB heating rates. The parameters that were chosen for this study were oven system volume, heater surface area and heater power. The CFD model was used to perform a design of simulations (DOS), and regression was used to analyze the DOS results. The regression results will be used to make recommendations on how to improve the PWB heating rate of the forced convective reflow system.
