Unlike standard surface probes that measure flat areas, the PTH hole ETP probe is engineered to enter small-diameter holes and measure the thickness of the copper barrel.<span id=\"477\" class=\"notranslate immersive-translate-target-wrapper\" lang=\"zh-CN\" translate=\"no\" data-immersive-translate-loading-id=\"\">\u00a0 <\/span><\/p>\n<p data-path-to-node=\"6\">Compatible with the Oxford CMI500 and the newer Hitachi CMI700 series, this ETP probe for CMI500 systems addresses the industry&#8217;s need for Non-Destructive Testing (NDT). It allows manufacturers to verify plating quality without sectioning the board, thereby reducing waste and speeding up the Quality Control (QC) process.<span id=\"478\" class=\"notranslate immersive-translate-target-wrapper\" lang=\"zh-CN\" translate=\"no\" data-immersive-translate-loading-id=\"\">\u00a0 <\/span><\/p>\n<h2 data-path-to-node=\"8\">2.

When the probe tip is inserted into a hole, it generates an electromagnetic field that induces eddy currents in the copper plating. The probe then measures the impedance change caused by these currents, which is directly proportional to the thickness of the copper.<span id=\"480\" class=\"notranslate immersive-translate-target-wrapper\" lang=\"zh-CN\" translate=\"no\" data-immersive-translate-loading-id=\"\">\u00a0 <\/span><\/p>\n<h3 data-path-to-node=\"10\">Key Technical Advantages:<span id=\"481\" class=\"notranslate immersive-translate-target-wrapper\" lang=\"zh-CN\" translate=\"no\" data-immersive-translate-loading-id=\"\">\u00a0 <\/span><\/h3>\n<ul data-path-to-node=\"11\">\n<li>\n<p data-path-to-node=\"11,0,0\"><b data-path-to-node=\"11,0,0\" data-index-in-node=\"0\">Surface Independent:<\/b> The hole copper thickness probe is uniquely designed to ignore surface copper, focusing exclusively on the barrel of the hole.
