Overview<\/h4>\r\n<p>\r\nVarious touch panels such as smartphones and tablets we touch.<\/br>\r\nThey detect electrical changes and recognize that a touch has been made.<\/br>\r\nConductivity testing of bare boards, which are manufactured by pattern printing, and touch panels is performed by cable harness testers can be applied to achieve this efficiently.<\/br>\r\n<\/p>\r\n<\/div>\r\n\r\n<h4>2.Testing touch panels and bare boards with cable harness testers <\/h4>\r\n<p>\r\nCable harness testers are good at testing multiple points at high speed.<\/br>\r\nThis advantage can be utilized for testing bare boards and touch panels.\r\nThe inspection can be realized at a considerably lower cost than with a dedicated checker.<\/br><\/p>\r\n\r\n<div class=\"c-spacer--s\">\r\n<h4>3. Touch panel methods and testing<\/h4>\r\n<p>As an example, we introduce the resistive film method.\r\nThis is a touch panel consisting of two electrode membranes with conductive patterns printed on them, and it functions by detecting a short circuit between the membranes when touched.\r\nAs electrical testing, it is necessary to measure and determine the wiring, resistance, and insulation resistance of the membrane.\r\nA short bar is placed at the end of the membrane to measure the resistance value, and the insulation testing is performed after the short bar is released.\r\nElectrical tests other than the resistive film method can also be realized.\r\n\r\nTranslated with www.DeepL.com\/Translator (free version)<\/br><\/p>\r\n<\/div>\r\n\r\n<h4>4.Bare board electrical testing<\/h4>\r\n<p>Bare board is a printed circuit board without mounted components. \r\nIt is necessary to check for electrical errors in conductive patterns. Test for continuity by using pin probes at the end of the board. Conduction resistance must be less than 1\u03a9, and non-conduction must be greater than 1M\u03a9. Harness testers can also measure resistance as low as the 0.01 \u03a9 level and insulation resistance as high as the 2000 M\u03a9 level.<\/p>\r\n\r\n<div class=\"c-spacer--s\">\r\n<h4>5. Inspection equipment suitable for touch panels and bare boards and customization<\/h4>\r\n<p>For electrical testing of touch panels and bare boards, the NMG+ series harness multitesters are the best choice.\r\nAll required test items can be performed.\r\nIf necessary, operational customization can be performed to realize smooth testing.<\/br>\r\nWe can also customize test specifications to meet the severe testing requirements.<\/br>\r\nWe have experience in testing with short bars and customizing to work with PLCs.<\/br><\/br>\r\n\r\nPlease contact NAC CORPORATION for quality and efficient testing.<\/br>\r\n<\/p>\r\n\r\n<\/div>","protected":false},"author":1,"featured_media":3142,"menu_order":16,"template":"","meta":[],"electrical-knowledge-cat":[127],"electrical-knowledge-tag":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge\/3141"}],"collection":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge"}],"about":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/types\/electrical-knowledge"}],"author":[{"embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":0,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge\/3141\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/media\/3142"}],"wp:attachment":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/media?parent=3141"}],"wp:term":[{"taxonomy":"electrical-knowledge-cat","embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge-cat?post=3141"},{"taxonomy":"electrical-knowledge-tag","embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge-tag?post=3141"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
