This session explores four newly developed test solutions for WLCSP. Frank Zhou, Smiths Connectors, presents a tip co-planarity analysis of a 200 \u00b5m pitch spring probe head for WLCSP. Zhou describes the structure of the probe head and spring contact probes along with key features and their impacts on co-planarity of probe head contactor tips. Paul Gunn, Test Tooling Solutions Group, reports on design for manufacturing (DFM) efforts in the development of a 0.2mm WLCSP test socket. Khaled Elmadbouly, Smiths Connectors, discusses the challenges of building fan-out printed circuit boards (PCB) for use as space transformers in probe heads for multi-site WLCSP with pitches greater than 0.2 mm.<\/p>\n<p><strong>\"Coplanarity Analysis of WLCSP Spring Probe Head\"<\/strong><br \/>\nJiachun (Frank) Zhou, Daniel DelVecchio, Cody Jacob<br \/>\nSmiths Connectors<\/p>\n<p><a href=\"\/premium\/welcome\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-129\" title=\"Click here to subscribe to PREMIUM content\" alt=\"\" src=\"\/premium\/wp-content\/uploads\/premium-video-non-subscriber.png\" width=\"480\" height=\"270\" srcset=\"https:\/\/www.testconx.org\/premium\/wp-content\/uploads\/premium-video-non-subscriber.png 480w, https:\/\/www.testconx.org\/premium\/wp-content\/uploads\/premium-video-non-subscriber-300x168.png 300w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/><\/a><\/p>\n<div style=\"clear: both;\"><\/div>\n<p><a href=\"\/premium\/wp-content\/uploads\/2015\/BiTS2015s3p1Zhou_9224.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-70\" alt=\"PDF-Icon 150x139\" src=\"\/premium\/wp-content\/uploads\/PDF-Icon-150x139.png\" width=\"75\" height=\"70\" \/><\/a>&nbsp;<a href=\"\/premium\/wp-content\/uploads\/2015\/BiTS2015s3p1Zhou_9224.pdf\" target=\"_blank\" \/>Presentation Download<\/a> <\/p>\n<p><strong>\"Pushing the envelope in DFM (Design for Manufacturing) for 0.2 mm Pitch WLCSP Socket\"<\/strong><br \/>\nPaul Gunn, Muhammad Syafiq, Takuto Yoshida<br \/>\nTest Tooling Solutions Group<\/p>\n<p><a href=\"\/premium\/welcome\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-129\" title=\"Click here to subscribe to PREMIUM content\" alt=\"\" src=\"\/premium\/wp-content\/uploads\/premium-video-non-subscriber.png\" width=\"480\" height=\"270\" srcset=\"https:\/\/www.testconx.org\/premium\/wp-content\/uploads\/premium-video-non-subscriber.png 480w, https:\/\/www.testconx.org\/premium\/wp-content\/uploads\/premium-video-non-subscriber-300x168.png 300w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/><\/a><\/p>\n<div style=\"clear: both;\"><\/div>\n<p><a href=\"\/premium\/wp-content\/uploads\/2015\/BiTS2015s3p2Gunn_7625.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-70\" alt=\"PDF-Icon 150x139\" src=\"\/premium\/wp-content\/uploads\/PDF-Icon-150x139.png\" width=\"75\" height=\"70\" \/><\/a>&nbsp;<a href=\"\/premium\/wp-content\/uploads\/2015\/BiTS2015s3p2Gunn_7625.pdf\" target=\"_blank\" \/>Presentation Download<\/a> <\/p>\n<p><strong>\"Space Transformer PCB For Testing 200 \u00b5m WLCSP\"<\/strong><br \/>\nKhaled Elmadbouly<br \/>\nSmiths Connectors<\/p>\n<p><a href=\"\/premium\/welcome\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-129\" title=\"Click here to subscribe to PREMIUM content\" alt=\"\" src=\"\/premium\/wp-content\/uploads\/premium-video-non-subscriber.png\" width=\"480\" height=\"270\" srcset=\"https:\/\/www.testconx.org\/premium\/wp-content\/uploads\/premium-video-non-subscriber.png 480w, https:\/\/www.testconx.org\/premium\/wp-content\/uploads\/premium-video-non-subscriber-300x168.png 300w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/><\/a><\/p>\n<div style=\"clear: both;\"><\/div>\n<p><a href=\"\/premium\/wp-content\/uploads\/2015\/BiTS2015s3p3Elmadbouly_1613.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-70\" alt=\"PDF-Icon 150x139\" src=\"\/premium\/wp-content\/uploads\/PDF-Icon-150x139.png\" width=\"75\" height=\"70\" \/><\/a>&nbsp;<a href=\"\/premium\/wp-content\/uploads\/2015\/BiTS2015s3p3Elmadbouly_1613.pdf\" target=\"_blank\" \/>Presentation Download<\/a> <\/p>\n<p>&nbsp;<\/br><br \/>\nReturn to the 2015 BiTS Workshop Archive <a title=\"Return to 2015 Index\" href=\"\/premium\/bits-workshop-2015-event-archive\">index page<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wafer level chip scale packages (WLCSP) are all the rage, and testing them is becoming easier and more cost effective as new probe technologies and probe card designs become available.
