What is the difference between RO4350B and FR-4?<\/strong><\/p>\n\n\n\n<p>While both can be processed using standard fabrication methods, they differ significantly in electrical performance. <strong>RO4350B<\/strong> is a hydrocarbon\/ceramic laminate designed for high-frequency applications (up to 77 GHz), offering a stable dielectric constant (Dk) and much lower signal loss (Loss Tangent of <strong>0.0037<\/strong>) compared to <strong>FR-4<\/strong> (Loss Tangent of <strong>~0.015\u20130.025<\/strong>). FR-4 typically struggles with signal integrity above 2\u20133 GHz, whereas RO4350B maintains its properties into the millimeter-wave range.<\/p>\n\n\n\n<p><strong>2. Is RO4350B compatible with standard lead-free soldering?<\/strong><\/p>\n\n\n\n<p>Yes. RO4350B has a high glass transition temperature (<strong>Tg &gt; 280\u00b0C<\/strong>) and a decomposition temperature (<strong>Td<\/strong>) of <strong>390\u00b0C<\/strong>. This makes it fully compatible with automated assembly and lead-free reflow soldering processes, which typically peak around 260\u00b0C. Its low Z-axis coefficient of thermal expansion (<strong>32 ppm\/\u00b0C<\/strong>) also ensures that plated through-holes (PTH) remain reliable during thermal cycling.<\/p>\n\n\n\n<p><strong>3. What is the Dielectric Constant (Dk) of Rogers 4350B?<\/strong><\/p>\n\n\n\n<p>The standard design Dielectric Constant for RO4350B is <strong>3.48 \u00b1 0.05<\/strong> at 10 GHz. This value is exceptionally stable across a wide frequency range, which is critical for designing controlled impedance transmission lines and wideband matching networks.<\/p>\n\n\n\n<p><strong>Note:<\/strong> For very thin materials (e.g., 0.004&#8243;), the Dk specification may shift slightly to 3.36.<\/p>\n\n\n\n<p><strong>4. How does RO4350B compare to RO4003C?<\/strong><\/p>\n\n\n\n<p>Both belong to the Rogers 4000 series, but the primary difference is the flame retardancy rating. <strong>RO4350B<\/strong> is <strong>UL 94 V-0<\/strong> rated, making it the industry standard for commercial and active devices where fire safety certification is required. <strong>RO4003C<\/strong> is not UL 94 V-0 rated, though it offers a slightly lower loss tangent (<strong>0.0027<\/strong>) and a slightly lower Dk (<strong>3.38<\/strong>), making it preferable for specific passive applications where every fraction of a decibel counts.<\/p>\n\n\n\n<p><strong>5. Does RO4350B require special plasma etching for through-hole plating?<\/strong><\/p>\n\n\n\n<p>No. Unlike PTFE-based materials (like the Rogers 5000 or 6000 series), RO4350B is a <strong>thermoset hydrocarbon<\/strong> laminate. This means it can be processed using standard epoxy\/glass (FR-4) techniques. It does <strong>not<\/strong> require specialized via preparation, such as sodium naphthenate or plasma etching, which significantly reduces manufacturing costs and lead times.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Get_RO4350B_PCB_Support\"><\/span>Get RO4350B PCB Support<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If your project involves RF or high-speed PCB design, selecting the right material is critical.<\/p>\n\n\n\n<p>We\u2019re happy to support you with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stack-up design<\/li>\n\n\n\n<li>RF PCB optimization<\/li>\n\n\n\n<li>Fast PCB &amp; PCBA production<\/li>\n<\/ul>\n\n\n\n<p>&#x1f4e7; <a>sales@bestpcbs.com<\/a><\/p>\n\n\n\n<p>Feel free to reach out \u2014 your project will be supported by engineers who understand real RF challenges.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>RO4350B PCB material is one of the most widely used laminates for high-frequency circuit design, especially in RF, microwave, and high-speed digital applications.
