These layers work together to transfer heat efficiently from components to the metal substrate. Each layer performs a specific thermal and electrical function that ensures stable circuit performance.<\/p>\n\n\n\n<p>The typical MCPCB stack structure includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Copper circuit layer<\/li>\n\n\n\n<li>Thermal dielectric layer<\/li>\n\n\n\n<li>Metal base layer<\/li>\n<\/ul>\n\n\n\n<p><strong>1. Copper Circuit Layer<\/strong><\/p>\n\n\n\n<p>The top layer contains copper traces that form the electrical circuit. This layer functions similarly to the copper layer in standard PCBs. Thicker copper improves current carrying capability and also spreads heat across the board surface. <strong>Copper thickness usually ranges from:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Copper Thickness<\/th><th>Typical Use<\/th><\/tr><\/thead><tbody><tr><td>1 oz (35 \u03bcm)<\/td><td>Standard LED and low-power circuits<\/td><\/tr><tr><td>2 oz (70 \u03bcm)<\/td><td>Power LED modules<\/td><\/tr><tr><td>3 oz \u2013 4 oz<\/td><td>High-current power electronics<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>2.

It electrically isolates the circuit from the metal base while still allowing heat to pass through. High thermal conductivity dielectric materials allow heat to move quickly from components into the metal base. <strong>Typical dielectric properties include:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Property<\/th><th>Typical Range<\/th><\/tr><\/thead><tbody><tr><td>Thermal conductivity<\/td><td>1 W\/mK \u2013 10 W\/mK<\/td><\/tr><tr><td>Thickness<\/td><td>50 \u03bcm \u2013 150 \u03bcm<\/td><\/tr><tr><td>Breakdown voltage<\/td><td>2 kV \u2013 6 kV<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Common dielectric fillers include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ceramic particles<\/li>\n\n\n\n<li>Aluminum oxide<\/li>\n\n\n\n<li>Silicon compounds<\/li>\n<\/ul>\n\n\n\n<p>These fillers increase thermal conductivity while maintaining insulation strength.<\/p>\n\n\n\n<p><strong>3. Metal Base Layer<\/strong><\/p>\n\n\n\n<p>The bottom layer of a <strong>pcb metal core<\/strong> acts as the primary heat sink. It spreads heat over a large surface area and transfers it to the external environment. Aluminum is widely used because it provides strong thermal performance at a reasonable cost. Copper offers the highest thermal conductivity but is heavier and more expensive. <strong>The most common base materials are:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Metal Base Type<\/th><th>Thermal Conductivity<\/th><\/tr><\/thead><tbody><tr><td>Aluminum<\/td><td>~200 W\/mK<\/td><\/tr><tr><td>Copper<\/td><td>~385 W\/mK<\/td><\/tr><tr><td>Steel<\/td><td>~50 W\/mK<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_choose_metal_core_PCB_material\"><\/span>How to choose metal core PCB material?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Selecting the right <strong><a href=\"https:\/\/www.bestpcbs.com\/blog\/2026\/03\/metal-core-pcb-material-mcpcb\/\" title=\"\">metal core pcb material<\/a><\/strong> depends on several engineering factors. The design must balance thermal performance, mechanical strength, electrical insulation, and manufacturing cost.<\/p>\n\n\n\n<p><strong>1. Thermal conductivity requirement<\/strong><\/p>\n\n\n\n<p>Heat dissipation is the main reason for using <strong>IMS PCB<\/strong> technology. The thermal conductivity of the dielectric layer determines how quickly heat moves into the metal base. Higher conductivity improves cooling performance. <strong>Typical ranges include:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Thermal Conductivity<\/th><th>Application<\/th><\/tr><\/thead><tbody><tr><td>1\u20132 W\/mK<\/td><td>Standard LED lighting<\/td><\/tr><tr><td>3\u20135 W\/mK<\/td><td>Automotive lighting<\/td><\/tr><tr><td>5\u201310 W\/mK<\/td><td>High-power electronics<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>2. Electrical insulation performance<\/strong><\/p>\n\n\n\n<p>Although the metal base conducts heat well, it must remain electrically isolated from the circuit layer. Reliable insulation prevents short circuits and protects sensitive components. <strong>Designers must verify:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dielectric breakdown voltage<\/li>\n\n\n\n<li>Insulation resistance<\/li>\n\n\n\n<li>Long-term reliability under temperature cycling<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Mechanical stability<\/strong><\/p>\n\n\n\n<p>Mechanical strength is also important when selecting <strong>metal core PCB materials<\/strong>. Aluminum substrates provide good rigidity while keeping board weight low. Copper base boards offer superior strength but increase overall board mass.<\/p>\n\n\n\n<p><strong>4. Manufacturing compatibility<\/strong><\/p>\n\n\n\n<p>Manufacturers evaluate whether the material supports standard processes such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>SMT assembly<\/li>\n\n\n\n<li>reflow soldering<\/li>\n\n\n\n<li>drilling and routing<\/li>\n\n\n\n<li>surface finishing<\/li>\n<\/ul>\n\n\n\n<p>A stable material simplifies production and improves yield.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/03\/metal-core-PCB-material-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/03\/metal-core-PCB-material-1.jpg\" alt=\"Metal Core PCB Material | High Thermal Conductivity MCPCB Base Materials\" class=\"wp-image-20890\" style=\"width:350px;height:auto\"\/><\/a><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_material_is_the_MCPCB_made_of\"><\/span>What material is the MCPCB made of?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>An <strong>MCPCB (Metal Core Printed Circuit Board)<\/strong> typically combines three major materials: copper circuitry, thermal dielectric, and a metal substrate.
