1点胶工艺的新进展显示文摘喷射点胶是一种通过动量使胶水快速从喷嘴中喷出的点胶工艺。Nordson ASYMTEK公司在1993年推出喷射技术,从此喷射点胶工艺开始在电子制造业被广泛使用。这是一个革命性的概念,因为在此之前点胶工艺只能通过针头点胶来完成,在针头点胶的过程中z轴需要上下运动,Dan Ashley 2013电子工业专用设备2013,,2:3
2底部填充工艺的瞬时温度环境管理(英文)显示文摘微电子组装的大部份工艺开发都要求将元件做到更小,以便在尺寸日益缩小的便携式设备上实现更多功能。阐述了大元件的底部填充,即一侧的尺寸超过15mm,底部填充的胶量介于30~50mg。大尺寸晶元的制造工艺要求比现有生产线更大的产能,这就给底部填充点胶带来更大的挑战。大元件的产能超过3000个/h时,需要点胶机点出非常多的胶水。如此多的胶水在出胶前通过点胶阀,这将会带来加热的问题-某些工艺要求出胶前胶水必须要加热。这会对胶点尺寸有影响,因为随着温度的变化,底部填充的胶水黏度也会随之变化,从而轻微影响点出的胶量。从而将影响晶元相邻的'非沾染区'。稳定的温度是点胶稳定性的保证,并且能帮助胶水流进晶元下方同时也有助胶水分离从而更容易喷射出来。从研究中可以观察到:系统温度环境(点胶机内部)对点胶的胶水质量有影响。Steven J Adamson Dan Ashley William Hassler Jared Wilburn 2009电子工业专用设备2009,,7:1
3威利剧院显示文摘正达拉斯演艺中心主席兼首席执行官Bill Lively说,'达拉斯演艺中心的创建是我们城市文化产业投资的一部分。演艺中心和表演公园会一道成为激动人心的全天候度假场所,这将会给达拉斯和整个地区带来活力。这个新的演艺中心将会让达拉斯及本地区的后代享受到来自于全世界的最好的音乐、戏剧、歌剧和舞蹈。'在传统的剧场中,与演出相关的附属空间的激增影响到了观演厅自身的空间。Haviland Argo Steve Chen Dan Choi Robert Donnelly Selva Gurdogan Jonathan Handel Stine Hansen Oke Hauser Andrew Heid Nahyun Hwang Ashley Klein Trine Kobbelvedt Natalia Ibanez Lario Soren Sigurd Larsen Mads Kristensen Filip Rem Beatriz Ramo Gro Sarauw Max Schwitalla Rooshad Shroff Gregers Tang Thomsen Lisa Tiedje Angelica Trevino Kristine Wander Monika Wittig Dolly Yarur 方朔 2012建筑技艺2012,,4:0
4Relationships Between Estimated Hourly Energy Balance and Body Composition in Professional Cheerleaders显示文摘Purpose We sought to describe and examine the interrelationships between energy intake,body composition,and estimated energy balance.Methods Using self-reported hourly food intake and formula-based energy expenditure(EE)protocols,19 female profes-sional cheerleaders(mean age 25.4 years)were assessed to obtain energy balance(EB)for a typical training day.Energy intake(EI)was predicted using the USDA Food Composition Database SR27,and EE was predicted using the Harris-Benedict equation plus a MET-based relative intensity activity scale.Body composition was predicted using a multi-current,8-mode segmental bioelectrical impedance analysis system.Hourly and daily EB was calculated from EI and EE data.Results Subjects reported a 24 h EI significantly below(P<0.001)the unadjusted predicted energy requirement(1482 kcal vs.2199 kcal,respectively),resulting in an average negative net EB of−720 kcal.Carbohydrate intake was significantly below the minimum recommended level(3.1 g/kg vs.6 g/kg,P<0.001)while protein and fat intakes met the recommended levels.Higher fat intake(g/kg)was significantly associated with a higher EI kcal/kg(r=0.726;P<0.001),which was sig-nificantly associated(r=−0.55;P=0.01)with a lower body fat percent(BF%).Using the median of BF%(20.9)as the cut point,participants with fewer hours in a negative EB had lower BF%(P=0.043)and those with lower BF%spent more time in an EB of±300 kcal(P=0.013).Conclusions These athletes reported low energy intakes that resulted in large EB deficits and/or more hours in a negative EB,which could be counterproductive for achieving a lean body composition overtime.Moriah P.Bellissimo Ashley D.Licata Anita Nucci Walter Thompson Dan Benardot 2019Journal of Science in Sport and Exercise2019,1,1:0
