The model name encodes its core features: &#8220;IT&#8221; stands for the brand ITEQ, &#8220;170&#8221; indicates a glass transition temperature (Tg) exceeding 170\u00b0C (verified at 175\u00b0C via DSC testing), &#8220;GR&#8221; denotes glass fiber reinforced substrate, &#8220;A&#8221; signifies a halogen-free environmental formulation (RoHS compliant), and &#8220;2&#8221; represents the second-generation optimized version. <\/p>\n\n\n\n<p>Compared to its predecessor (e.g., IT-170GRA1), it achieves reduced dielectric loss (Df\u22480.012) and enhanced anti-CAF (anti-ionic migration) performance. Defined as an epoxy resin\/glass fiber cloth-based high Tg halogen-free CCL, it combines low signal loss, high thermal resistance (Tg=175\u00b0C), and high reliability, making it ideal for high-speed scenarios including 5G communication systems, server backplanes, and automotive electronic control units.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/10\/M-5.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/10\/M-5.jpg\" alt=\"What Is IT170GRA2?\" class=\"wp-image-14472\" style=\"aspect-ratio:3\/2;object-fit:contain\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"IT170GRA2_Material_Datasheet\"><\/span>IT170GRA2 Material Datasheet<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<style>\n#content tr td {\n    border-top: 1px solid black;\n}\n<\/style>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Parameter Category<\/strong><\/td><td><strong>Specification Value<\/strong><\/td><td><strong>Test Standard<\/strong><\/td><\/tr><tr><td>Glass Transition Temp (Tg)<\/td><td>175\u00b0C<\/td><td>DSC Method (IPC-TM-650 2.4.25)<\/td><\/tr><tr><td>Dielectric Constant (Dk)<\/td><td>3.85\u00b10.05 @10GHz<\/td><td>IPC-TM-650 2.5.5.13 (Stripline Method)<\/td><\/tr><tr><td>Dielectric Loss (Df)<\/td><td>0.012 @10GHz<\/td><td>Same as Dk (Stripline Method)<\/td><\/tr><tr><td>CTE (Coefficient of Thermal Expansion)<\/td><td>X\/Y Axis: 12 ppm\/\u2103;Z Axis: 45 ppm\/\u2103 (50\u2013260\u00b0C)<\/td><td>TMA Method (IPC-TM-650 2.4.24)<\/td><\/tr><tr><td>Anti-CAF Performance<\/td><td>Passed 85\u00b0C\/85%RH, 50V, 1000h<\/td><td>IPC-650 2.6.25<\/td><\/tr><tr><td>Flame Retardancy<\/td><td>UL 94 V-0<\/td><td>UL Standard<\/td><\/tr><tr><td>Copper Foil Peel Strength<\/td><td>\u22650.7 N\/mm (Normal Condition)<\/td><td>IPC-TM-650 2.4.8<\/td><\/tr><tr><td>Thickness Range<\/td><td>0.04\u20133.2 mm<\/td><td>None (Basic Dimension Specification)<\/td><\/tr><tr><td>Copper Thickness Range<\/td><td>1\/3oz\u20134oz<\/td><td>None (Supporting Process Parameters)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Choose_IT170GRA2_Material_for_High_Speed_PCB\"><\/span>Why Choose IT170GRA2 Material for High Speed PCB?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Reasons Why Choose<a href=\"https:\/\/www.bestpcbs.com\/blog\/2025\/10\/it170gra2-material-selection-guide-for-high-speed-pcb\/\" title=\"\"> IT-170GRA2 Material<\/a> for High Speed PCB<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High-Frequency Signal Low-Loss Transmission: <\/strong>Df value 0.009\u20130.012 (@10GHz) reduces signal loss by approximately 40% compared to FR-4, ensuring signal integrity for 25Gbps+ high-speed links (e.g., PCIe 5.0) and minimizing data transmission errors.<\/li>\n\n\n\n<li><strong>Stable Performance in High-Temperature Environments:<\/strong> Tg=175\u00b0C supports lead-free soldering processes, Z-axis CTE of 45ppm\/\u2103 minimizes interlayer separation, and passing 85\u00b0C\/85%RH 1000h CAF test extends service life in high-temperature scenarios like 5G base stations and automotive electronics.<\/li>\n\n\n\n<li><strong>Environmentally Compliant and Safe: <\/strong>Halogen-free formulation meets RoHS\/IEC 61249-2-21 standards, UL 94 V-0 flame retardancy enhances terminal product safety, complying with global environmental regulations.<\/li>\n\n\n\n<li><strong>High Process Compatibility and Cost Efficiency: <\/strong>Supports advanced processes like laser drilling and HDI stacking, copper foil peel strength \u22650.7N\/mm prevents detachment during processing.

Signal Rate Requirement Assessment<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Determine if the signal rate is \u226456Gbps PAM4 (equivalent frequency \u226428GHz). For rates exceeding this standard, ultra-low loss materials like Panasonic Megtron 6 are required. For lower rates, proceed to temperature adaptability verification. <\/li>\n<\/ul>\n\n\n\n<p><strong>2. Operating Temperature Adaptability Verification<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Confirm if long-term operating temperature is \u2264130\u00b0C. For extreme environments exceeding 150\u00b0C (e.g., engine ECU), polyimide substrates must be used to ensure thermal stability. If temperature is \u2264130\u00b0C, proceed to cost budget analysis. <\/li>\n<\/ul>\n\n\n\n<p><strong>3. Cost Budget Matching Analysis<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Evaluate if the project budget can accommodate \u22651.5 times the cost of FR-4.
