    Abstract: The invention relates to a placement method for placement of a chip component (10) on a flexible substrate (20), comprising: providing a support face (21 ) comprised of the flexible substrate (20) or of a support structure (70) to be aligned with the flexible substrate (20); administering a chip (10) to the support face (21 ); generating with a pressure chamber (60) an air flow in an out of plane orientation relative to the support face (21); and directing the chip (10) to a placement position (30) by means of a directional structure (40) provided on the support face (21 ). In particular the chip (10) is levitated from the support face (21 ) by said air flow or by vibrational contact between the support face (21 ) and the chip (10) induced by said air flow. When the support face (21 ) is comprised by a support structure (70) distinct from the flexible substrate (20), the support face (21 ) is aligned with the flexible substrate (20). Accordingly, air cushion or intermittent contact forces (modulated in time and space using modulated micro-features) can be used to provide local interactions with the micro-part (chip) (10) so as to position micro-parts (10) with reference to micro-features arranged on the flexible substrate (20). The placement method may be applied for self-assembly of chips (10) on the flexible substrate (20), using a reel-to-reel process.

    Abstract translation: 本发明涉及一种用于将芯片部件(10)放置在柔性基板(20)上的放置方法,包括:提供由柔性基板(20)或支撑结构(70)组成的支撑面(21), 与柔性基板(20)对准; 向所述支撑面(21)施加芯片(10); 用压力室(60)产生相对于支撑面(21)的面外取向的空气流; 以及通过设置在所述支撑面(21)上的定向结构(40)将所述芯片(10)引导到放置位置(30)。 特别地,芯片(10)通过所述空气流从支撑面(21)悬浮,或通过由所述空气流引起的支撑面(21)和芯片(10)之间的振动接触。 当支撑面(21)由与柔性基板(20)不同的支撑结构(70)构成时,支撑面(21)与柔性基板(20)对准。 因此,可以使用气垫或间歇接触力(使用调制的微特征在时间和空间上调制)以提供与微零件(芯片)(10)的局部相互作用,以便以参考方式定位微零件(10) 涉及布置在柔性基板(20)上的微特征。 放置方法可以应用于使用卷到卷工艺在芯片(10)上自组装在柔性基板(20)上。
