据国外媒体报道，业内消息人士称，韩国电池制造商 SK 创新和美国汽车制造商福特汽车将在美国成立一家电池合资企业，以确保电动汽车电池的稳定供应。 据知情人士透露，这两家公司计划在周四晚些时候宣布一份关于合资企业的谅解备忘录。 福特拒绝置评，只是说SK是一家很有价值的供应商，并表示计划在美国东部时间周四上午9点（北京时间周四晚21点）召开电话会议，提供“福特电池的最新情况”。SK创新在一份声...[详细]
目前国内生产 LED 灯具，一般只在设计阶段关心光参数。选择什么样的芯片，配什么样的驱动，如何散热等等。但是在生产过程中却没有行之有效的控制手段，包括大公司也一样。如何在生产过程中全方位的控制光参数？ 首先是要在来料检验检测每卷芯片的参数是否和每卷的标签是否一致，一般来说大品牌的芯片部太可能整卷出错，所以检测一两颗即可，参数主要包括光通量，色温，功率，电流，电压等。小品牌的产品就要增加抽样比...[详细]
