As original Hitachi (Oxford) parts, these Crystal Tips are engineered to maintain the gauge\u2019s high-precision measurement performance, critical for surface copper thickness testing in PCB manufacturing. The crystal material enables stable eddy current induction\u2014key to accurate readings of electroless and electrodeposited copper layers. Compatible exclusively with the CMI165 probe head (CMI165 probe head), they integrate seamlessly with other testing accessories like Nylon Brush (for cleaning), calibration standard plate (for post-replacement calibration), and Antistatic PP Sheet (for storage), forming a reliable quality control chain for PCB copper testing.<\/p>\n<h2 data-path-to-node=\"6\">2. Hitachi Cmi165 Tips MaterialandTechnology<\/h2>\n<p data-path-to-node=\"7\">The superior performance of the Hitachi Cmi165 Tips\u00a0is rooted in advanced material science and application of the Micro-Resistance principle.<\/p>\n<h3 data-path-to-node=\"8\">1. Material (High-Purity Alloy)<\/h3>\n<ul data-path-to-node=\"9\">\n<li>\n<p data-path-to-node=\"9,0,0\"><b>Composition:<\/b> The tips are made from a proprietary high-purity conductive alloy. This material choice is critical to ensure a stable and repeatable electrical contact with the copper trace, minimizing the inherent electrical noise or &#8220;contact resistance.&#8221;<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,1,0\"><b>Wear Resistance:<\/b> The material possesses excellent wear-resistant properties, crucial for maintaining tip geometry and accuracy over thousands of measurements, thus extending the CMI165 Tips lifetime before replacement is necessary.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"10\">2. Technical Principle (Targeted Micro-Resistance)<\/h3>\n<p data-path-to-node=\"11\">The Hitachi Cmi165 Tips utilizes a micro-resistance method, where the tips must:<\/p>\n<ul data-path-to-node=\"12\">\n<li>\n<p data-path-to-node=\"12,0,0\"><b>Establish Stable Current Flow:<\/b> The tips ensure that the small, controlled current flow necessary for the measurement is consistent across the copper trace.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"12,1,0\"><b>Isolate Measurement:<\/b> The tip&#8217;s geometry and contact area are meticulously designed to limit the measurement field, preventing interference from the substrate or adjacent fine traces\u2014a critical factor for accurate HDI PCB Testing.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"13\">3.
