WebMar 25, 2015 · Three pre-warpage copper substrates with pre-warpage magnitude of 0 μm, 310 μm and 387 μm were selected for the verification experiment in this study. Three samples were soldered in the vacuum reflow oven VADU100 and the transient temperatures subjected to copper substrate were measured and recorded by means of thermocouples … Webwarpage in Fig. 7, while the two-shot sequential overmolding is also completed and measured as shown in Fig. 8. Obviously, when the width of 2nd shot is 2 mm, the warpage of the whole part displays outward. Keeping the 1st shot fixed dimension and following the previous procedures, we have done various material
