Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted. It was found in our drop tests that the root cause of lead-free solder joints under drop impact was the combined effect of mechanical shock and PCB bending vibration.

Experiment results indicate the more desirable orange-pomace bread can be produced if the orange pomaces are not washed in water, the sample is oven-dried and the particle diameter distribution of the orange pomaces in use is less than 250 μm. Due to the fact that the water-absorption ability of orange pomaces is strong, we may want to mix pomaces with the oil of the recipe first during the process of making orange-pomace bread and add the mixture later to the formation of the structure of gluten. Under the condition that orange pomaces account for 14% of the ingredients, the adjusted optimal condition calls for extra 2% of oil, 3% of water and 4% of gluten, the amount of yeast is increased to 2% and the fermentation time is 2 hours. The orange-pomace bread made under this condition has a specific volume of 5.19 cm3/g and receives a rating of 9.5 point. It is close to the American-style sweat bread of the control group. It is also found that the addition of orange pomaces can help slow down the rise in hardness, gumminess and chewyness of the bread during the time it is in storage.

实验结果显示，柳橙果渣於制备过程不经过清水漂洗、利用烘箱乾燥样品、使用粒径分布尺寸小於250 μm之柳橙果渣对於制作柳橙果渣面包有较理想之结果，另外由於柳橙果渣吸水性强，於制作果渣面包时需将柳橙果渣先与配方中之油脂混合，待面团搅拌成筋后再加入。14%柳橙果渣添加量下，配方上调整的最适条件为额外添加2%油脂、3%水量、4%面筋，并将酵母量增加为2%，发酵时间为2 h，所制作出之柳橙果渣面包比体积为5.19 cm3/g，评分为9.5分，接近控制组美式甜面包，并且发现添加果渣制作面包可以减缓面包於储藏期间硬度、胶性度、咀嚼度上升之程度。
