今年以来，随着国内半导体企业加快国产替代进程，位于萧山河上镇的科百特短期内订单激增，配 套零部件需求也急剧上升，但现有零部件外协企业（以外省为主）的机加工能力、沟通效率、交付质量 等难以满足需求，拓展本地化、高质量的协作渠道成为当务之急。 得知企业需求后，萧山区经信局联动区助企专班、河上镇，一场全区范围的产业链"配对"随即展 开。从规上企业到规下企业，在数千家精密加工企业中找到合适的配套企业并非易事。萧山区经信局相 关负责人告诉记者，由于科百特的产品主要应用于半导体行业，对供应商设置的"门槛"较高。比如，部 分塑料件需在洁净车间生产，还需要具备恒温操作环境；部分金属件对表面光洁度要求极高。 最终，经过细致摸排和严格比对，萧山区助企服务办为科百特筛选出15家潜力企业作为重点对接对 象，并提供一对一的产业链对接服务。经过多轮打样，目前凌博机械、明顺精密两家企业的金属件机加 工已通过科百特验收并进入合作供应商名单，并已开启订单合作。 这场由萧山助企服务精准促成的合作，意义远超订单本身。萧山区经信局相关负责人表示，科百特 作为全球领先的过滤膜企业，正攻关1000多道集成电路工序的进口零部件替代，其3000多个研发任务 ...
