Thermal Viability First<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Calculate required thermal vias using: N = (P \u00d7 Rth)\/\u0394T, where P = power (W), Rth = thermal resistance (\u00b0C\/W), and \u0394T = max allowable temp rise. Aim for \u22656 vias (0.5mm dia) under high-power devices.<\/li>\n\n\n\n<li>For LEDs &gt;1W, ensure die attach area covers \u226570% of the aluminum base. Use white solder mask to reflect unused light and reduce thermal load.<\/li>\n<\/ul>\n\n\n\n<p><strong>2. Component Placement Logic<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Group heat sources (e.g., regulators, drivers) in a central &#8220;thermal zone&#8221; with direct aluminum exposure. Keep analog\/RF components \u22655mm from this zone to avoid thermal noise.<\/li>\n\n\n\n<li>Orient power transistors with drain\/collector pads parallel to aluminum grain direction for optimal heat spreading.<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Copper-Aluminum Bonding<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use 35\u00b5m (1oz) copper for signals; switch to 70\u00b5m (2oz) for power traces. Avoid abrupt copper weight transitions (&gt;1oz difference) to prevent lamination cracks.<\/li>\n\n\n\n<li>Specify &#8220;button plating&#8221; for plated through-holes (PTHs) to reinforce aluminum-copper joints.<\/li>\n\n\n\n<li>Dielectric Layer Control<\/li>\n\n\n\n<li>Request dielectric thickness tolerance of \u00b110%. Thinner layers (50\u00b5m) improve thermal performance but risk electrical breakdown; validate with V = E \u00d7 d (E = dielectric strength, d = thickness).<\/li>\n\n\n\n<li>For high-voltage (&gt;100V) designs, add a 50\u00b5m polyimide overlay on critical traces.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Mechanical Stress Mitigation<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Add 1mm chamfered edges to aluminum cores to prevent sharp corners causing board flex. Use 3M&#x2122; thermal tapes instead of screws for non-critical assemblies to reduce thermal impedance.<\/li>\n\n\n\n<li>For assemblies with &gt;5kg weight, specify aluminum thickness \u22652.0mm and add 2mm mounting holes spaced \u226550mm apart.<\/li>\n<\/ul>\n\n\n\n<p><strong>5. Assembly Compatibility<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Require wave soldering temps \u2264260\u00b0C for aluminum PCBs. Use low-melting-point solder (Sn42\/Bi58) for mixed-technology boards (SMT + through-hole).<\/li>\n\n\n\n<li>Add 0.2mm solder mask dams between fine-pitch SMT pads to prevent solder wicking on aluminum surfaces.<\/li>\n<\/ul>\n\n\n\n<p><strong>6. Testing Protocols<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Perform IR thermal imaging at 80% max load for 2 hours. Target \u0394T &lt;15\u00b0C between hottest component and ambient. Validate dielectric integrity with 500V Hipot testing; fail if leakage current &gt;5mA.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/07\/2-3.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/07\/2-3.jpg\" alt=\"Aluminum PCB Design Guidelines\" class=\"wp-image-11197\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Aluminum_Base_PCB_Manufacturing_Processes\"><\/span>Aluminum Base PCB Manufacturing Processes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Below are aluminum base PCB manufacturing processes:<\/p>\n\n\n\n<p><strong>1.
