IEC 62899-302-2-2018 印刷电子产品--第302-2部分:设备--喷墨--基于图像的液滴体积测量 Printed electronics – Part 302-2: Equipment – Inkjet – Imaging-based measurement of droplet volume

This part of IEC 62899 specifies the method for determining accurate inkjet droplet volume based on images obtained by drop-in-flight measurement systems. It does not apply to imaging systems using interference fringes, such as holography or phase doppler anemometry. This document is not limited to drop-on-demand inkjet systems, but might not be applicable to continuous inkjet or liquid dispensing systems. This document includes a description of the issues concerning such measurements and consideration of the limits to measurement accuracy.dition 1.0 2018-05 INTERNATIONAL STANDARD Printed electronics – Part 302-2: Equipment – Inkjet – Imaging-based measurement of droplet volume IEC 62899-302-2:2018-05(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2018 IEC, Geneva, Switzerland All rights reserved.
